Background: Varicose pubic collateral veins are a rare phenomenon secondary to obstruction of the common femoral vein, left external iliac, or common iliac vein. This article aims to describe the clinical case of a 75-year-old female patient who presented with varicose collateral suprapubic veins.Case report: A 75-year-old female patient from a rural area in Colombia presented to the emergency department complaining of a 4-day history of edema, erythema, and pain in the suprapubic region. The patient presented with large varicose veins in the suprapubic region with erythema, warmth, and pain on palpation. A computer tomography scan of the abdomen and pelvis showed suprapubic varicose veins and contrasted in venous phase ruled out iliac vein obstruction. To rule out paraneoplastic syndrome, tumor markers, a transvaginal ultrasound, esophagogastroduodenoscopy and rectosigmoidoscopy were obtained and found to be negative. Anticoagulation with warfarin 5 mg daily and bridge therapy with enoxaparin was initiated.Conclusion: We presented the case of a patient with varicose collateral suprapubic veins of unknown origin, who received anticoagulation with warfarin and analgesic management with subsequent resolution of symptoms.

Background: Equine cutaneous habronemiasis is common in the distal regions of the limbs. Organophosphates, appliedsystemically, one previously used treatment, which is highly effective, but currently in disuse, due to the risks of intoxication. Regional perfusion is a potential technique for distal limb wounds, since, in addition to being used in low doses, itprevents systemic circulation of the drug and possible intoxication, and has a lower treatment cost. The current work aimedto perform clinical, laboratory, and venography evaluations of the use of trichlorfon in regional intravenous perfusion, asa possible form of treatment for cutaneous habronemosis in the distal region of equine limbs.Materials, Methods & Results: Twelve equines were used, divided into 2 groups, with the left thoracic limb (LTL) beingthe test limb, and the right thoracic limb (RTL) the control limb. At moment zero (M0), distal radiography and venographywere performed. The tourniquet was then loosened and after 5 min, at moment one (M1), the tourniquet was repositionedfor 1.25 mg/kg (G1) and 5.5 mg/kg (G2) trichlorfon injections into the left thoracic limb, diluted in 20 mL of Ringers lactate solution, and 20 mL of Ringers lactate solution was applied to the right thoracic limb. The tourniquet was maintainedfor 30 min after infusion in both groups. At moment 2 (M2), 4 days later, blood tests, radiography, and venography wererepeated. Every day between M0 and M2, physical examinations were performed, including measurement of the pastern,fetlock, and coronet band, and a lameness examination. There were no significant alterations in clinical parameters, behavior, and appetite. In the blood cell count, there was an increase in leukocytes on D4 in G2, although remaining withinthe reference values for the species. The biochemical tests showed no alterations. There were no changes in the circumferences evaluated and 4 equines from G2 presented lameness in the LTL and...

Axillary vein puncture guided by ultrasound (US-Ax) versus cephalic vein dissection in pacemaker and defibrillator implant: a multicenter randomized clinical trial is a recently published study in which 88 patients were randomized in a 1:1 fashion to one of the two methods. Even being performed by operators with not previous ultrasound-guided axillary vein puncture experience, this group presented a higher success rate, lower procedural time and comparable complication incidence.
Lay abstract Recently a study evaluating two different approaches to cardiac devices implant was published. In the study, 88 patients were assigned to one of two methods for this procedure. The operators had no previous experience in one of the methods, but it demonstrated a higher success rate, took less time and had the same number of complications as the method the doctors had experience in. This paper evaluated the study and discusses what changes might take place in clinics as a result of these findings.

Cerebral venous thrombosis is a less common but relevant cause of stroke in adults. The clinical manifestations are nonspecific leading frequently diagnostic delays, so imaging findings are is of vital importance. Conventional imaging modalities, namely computed tomography and magnetic resonance imaging (MRI), allow identification of the thrombus and parenchymal involvement due to venous congestion to a variable degree, but this entity may appears as a nonexpected finding in a nonvenographic study. computed tomography and MRI venographies allow noninvasive confirmation of the diagnosis and adequate characterization of the extent of the thrombus and acute complications, both of them being robust diagnostic techniques. MR venography also can be done without the use of contrast media, which is especially important in certain clinical situations. Cerebral venous thrombosis needs follow-up, and imaging plays a key role in detection of late complications of the disease, including dural arteriovenous fistulas and intracranial hypertension due to veno-occlusive disease. Knowledge of other diseases and conditions that may mimic a thrombus is needed to avoid wrong diagnosis. In this article, we conduct a pictorial comprehensive review of cerebral venous thrombosis, including also the technical aspects of different imaging modalities, diagnosis and acute complications, follow-up, late complications and potential imaging mimics.

Abstract Objectives: to analyze, evaluate and describe the usefulness of petrosal sinus sampling for diagnosing central Cushing's syndrome. Materials and methods: the technical aspects and results of bilateral venous sampling of the petrosal sinuses at the Hospital Universitario San Vicente de Paul in Medellín, Colombia, from January 1, 2012 to December 31, 2018, were analyzed. Results: the average age was 43.3 years, with a range from 19 to 69 years. Laterality could be shown in 68.2% of cases, with a tendency to be located on the left in 53.3%. The central source of ACTH production could be shown in 95.4% of cases, with a basal average central/peripheral ratio of 21.7, and 70.8 after stimulation. All samples at 3, 5 and 10 minutes were confirmatory following stimulation. Conclusion: in our retrospective study, petrosal sinus catheterization provided laboratory confirmation of the central source of ACTH production in a high percentage of patients, with no immediate complications.

OBJECTIVE: We evaluated the frequency of significant left renal vein (LRV) compression, also called the nutcracker phenomenon (NCP), in a normal asymptomatic population. METHODS: The present retrospective descriptive anatomic study analyzed the data from high-definition renal computed tomography (CT) angiography of living kidney donors. A total of 324 CT examinations were evaluated for signs of LRV compression, including the beak sign, aortomesenteric angle <41°, LRV diameter ratio ≥4.9, and beak angle ≥32°. The presence of pelvic varicose veins and the left gonadal vein in the proximal and mid-portion (considered dilated if >0.5 cm) were also evaluated. Anthropometric and laboratory (urine erythrocyte count) data were collected from the medical records. Statistical inference was calculated using Fisher's exact test and Student's t test. RESULTS: The mean aortomesenteric angle was 53.1° in women and 58.7° in men (P = .044). The beak sign and beak angle were present in 15.3% and 9.8%, respectively, and both had a greater prevalence in the women (P = .01). An aortomesenteric angle <41° was identified in 30.5%, with a greater prevalence in women (P < .01). The diameter ratio was positive in 0.7% of the cases, with no difference between the sexes. A left gonadal vein >0.5 cm was more prevalent in women in both the proximal and the mid-portions (P < .01). Although analysis stratified by positive criteria (3 or 4) showed no difference between the sexes, a positive correlation was found with younger age (P < .01). The limitations included the absence of a nutcracker syndrome (NCS) population; the lack of a renocaval pressure gradient, because of the need for intervention; the absence of other types of imaging studies, such as duplex ultrasound scan; and the absence of female parity data. CONCLUSIONS: The NCP and NCS CT criteria were present with a high frequency in healthy individuals. Women and younger individuals showed a greater prevalence of compression findings in the aortomesenteric axis. Revision of the current NCP and NCS criteria with a distinct categorization between sex, age, and body mass index is recommended to better evaluate LRV compressive events.

Objective: To investigate power of computed tomography venography (CTV) to identify and characterize iliac vein obstruction (IVO) compared with intravascular ultrasound (IVUS) examination in highly symptomatic patients with chronic venous disease (CVD). Methods: CVD CEAP C3-6 limbs with visual analog scale for pain score of greater than 3 and/or Venous Clinical Severity Scale of greater than 8 were prospectively investigated with CTV and IVUS examination. The segment of maximum IVO was verified and categorically classified: group I, 0% to 49%; group II, 50% to 79%; and group III, 80% or greater. The CTV's screening power to detect the point and degree of maximum IVO was compared with IVUS. Results: The CTV point of maximum IVO was 80% in the left limb, 10% in the right limb, 10% bilaterally; 2% in the inferior vena cava; 91% in the common iliac vein (CIV) confluence (41.6% below the CIV confluence, 34.5 at the CIV confluence, and 23.9% above the CIV confluence); 7% at the external iliac vein (kappa index 0.841; P < .001, when compared with IVUS). The distal venous segment considered free of obstruction was above inguinal ligament: 68% (CIV, 47%; external iliac vein, 21%) 32% below the inguinal ligament (common femoral vein, 26%; deep femoral vein, 6%) (kappa index 0.671; P » .023, when compared with IVUS). The power of CTV to detect an IVO of 50% or greater (groups II and III) when compared with IVUS achieved a sensitivity and specificity ratio of 94.0% and 79.2%, respectively. The positive predictive value was 94%, the negative predictive value was 79.1%, accuracy was 86.7% (kappa, 0.733), and interobserver agreement was 92.1% (95% confidence interval, 87.1-97.7; kappa, 0.899). Conclusions: CTV is a powerful screening method in determining the precise point of compression and classifying IVO in limbs with symptomatic CVD when compared with IVUS. The prevalence of an obstruction above the iliac vein confluence is significant and should be considered in iliac vein stenting treatment strategy. The tomographic classification system proposed here may help to define the optimum technique of treatment, prognosis, and comparison of outcome results. (J Vasc Surg: Venous and Lym Dis 2019;-:1-10.)

PURPOSE: To report final 2-year outcomes with the Sentry bioconvertible inferior vena cava (IVC) filter in patients requiring temporary protection against pulmonary embolism (PE). MATERIALS AND METHODS: In a prospective multicenter trial, the Sentry filter was implanted in 129 patients with documented deep vein thrombosis (DVT) and/or PE (67.5%) or who were at temporary risk of developing DVT/PE (32.6%). Patients were monitored and bioconversion status ascertained by radiography, computed tomography (CT), and CT venography through 2 years. RESULTS: The composite primary 6-month endpoint of clinical success was achieved in 97.4% (111/114) of patients. The rate of new symptomatic PE was 0% (n = 126) through 1 year and 2.4% (n = 85) through the second year of follow-up, with 2 new nonfatal cases at 581 and 624 days that were adjudicated as not related to the procedure or device. Two patients (1.6%) developed symptomatic caval thrombosis during the first month and underwent successful interventions without recurrence. No other filter-related symptomatic complications occurred through 2 years. There was no filter tilting, migration, embolization, fracture, or caval perforation and no filter-related deaths through 2 years. Filter bioconversion was successful for 95.7% (110/115) of patients at 6 months, 96.4% (106/110) of patients at 12 months, and 96.5% (82/85) of patients at 24 months. Through 24 months of follow-up, there was no evidence of late-stage IVC obstruction or thrombosis after filter bioconversion or of thrombogenicity associated with retracted filter arms. CONCLUSIONS: The Sentry IVC filter provided safe and effective protection against PE, with a high rate of intended bioconversion and a low rate of device-related complications, through 2 years of follow-up.

The Bridge Occlusion Balloon is a compliant balloon, specifically designed for temporary Superior vena cava occlusion in case of Superior Vena Cava laceration during lead extraction procedures. We here report the first case, using Bridge Occlusion Ballon for a venous angioplasty in a patient with dysfunctional pacemaker leads and symptomatic Superior Vena Cava occlusion. After successful lead extraction, venography was showing a narrow venous canal. Therefore, venous angioplasty using the Bridge balloon was performed. Especially for high-risk lead extraction cases in patients with Superior Vena Cava stenosis, the Bridge Occlusion Ballon might be used as a combination of a safety-net in case of Superior Vena Cava perforation and for Superior Vena Cava angioplasty.

Malformations of inferior vena cava (IVC) as agenesis are a rare congenital anomaly and cause of deep venous thrombosis (DVT) of lower limbs and should be investigated in young patients of unknown aetiology. Treatment with mechanical thrombectomy and thrombolysis can be considered in certain cases of DVT, promoting rapid clot removal, and has also been shown to be an effective treatment in acute DVT. We present a case of acute lower limb DVT associated with IVC agenesis in which Alteplase thrombolysis was used and thrombus aspiration with catheter bilaterally, with subsequent angioplasty of the common and external iliac, obtaining satisfactory results.

Parastomal variceal bleeding (PVB) is a serious complication occurring in up to 27% of patients with an ostomy and concurrent cirrhosis and portal hypertension. The management of PVB is difficult and there are no clear guidelines on this matter. Transjugular intrahepatic portosystemic shunt (TIPS), sclerotherapy, and /or coil embolization are all therapies that have been shown to successfully manage PVB. We present a case series with five different patients who had a PVB at our institution. The aim of this case series is to report our experience on the management of this infrequently reported but serious condition. We also conducted a systemic literature review focusing on the treatment modalities of 163 patients with parastomal variceal bleeds. In our series, patient 1 had embolization and sclerotherapy without control of bleed and expired on the day of intervention due to hemorrhagic shock. Patient 2 had TIPS in conjunction with embolization and sclerotherapy and had no instance of rebleed 441 days after therapy. Patient 3 did not undergo any intervention due to high risk for morbidity and mortality, the bleed self-resolved and there was no further rebleed, this same patient died of sepsis 73 days later. Patient 4 had embolization and sclerotherapy and had no instance of rebleed 290 days after therapy. Patient 5 had TIPS procedure and was discharged five days post procedure without rebleed, patient has since been lost to follow-up.

O objetivo deste estudo foi descrever a técnica de venografia retrógrada podal em vacas, comparando os acessos da veia digital dorsal comum III com a digital comum II ou IV, nos membros torácicos e pélvicos, mediante a administração de dois diferentes volumes de contraste. Foram utilizados 53 membros torácicos e pélvicos de 14 vacas, com o torniquete de borracha posicionado a 5cm proximal aosparadígitos. Administraram-se 10mL do diatrizoato de meglumina em 24 membros (grupo 1), sendo 13 na veia digital dorsal comum III pelo acesso 1 (A1) e 11 na digital II ou IV no acesso 2 (A2). No grupo 2, administraram-se 20mL em 29 membros, sendo 15 pelo A1 e 19 pelo A2. Após a administração do contraste, as radiografias foram repetidas a cada 20 segundos até 120 segundos. O grau de preenchimento vascular foi maior no grupo 2, não diferindo entre membros e acessos venosos. Conclui-se que a administração de 20mL de contraste apresentou melhor preenchimento vascular e radiopacidade, não havendo diferença entre 20 e 120 segundos após a administração do contraste na qualidade radiográfica, independentemente do acesso venoso.(AU)
The aim of this study was to describe the technique of retrograde venography foot in cows, comparing the approaches of the dorsal common digital vein III with the digital commons II or IV, thoracic and pelvic by administering two different volumes of contrast members. Fifty three fore and hindlimbs of 14 cows were used, a rubber tourniquet was placed at 5cm above accessory digit. Diatrizoatemeglumine was administered at 10mL to 24 members (group 1), 13 dorsal common digital vein III for access 1 (A1), and 11 digital II or IV access 2 (A2). In group 2 20mL was administered to 29 members, 15 by 19 in A1 and A2. After contrast administration, the radiographs were repeated every 20 seconds until 120 seconds. The degree of vascular filling was greater in group 2, independent of venous access, member or moment. There was no significant difference in the degree of radiopacity of radiographic images when compared to the venous access, time and a member of both groups. We conclude that administration of 20mL of contrast showed better vascular filling and radiopacity, with no difference between 20 and 120 seconds after contrast administration in independent radiographic quality venous access.(AU)

BACKGROUND: Pelvic venous insufficiency may cause pelvic congestion syndrome that is characterized by chronic pelvic pain exacerbated by prolonged standing, sexual activity or menstrual cycle. It may be treated by embolizing the dysfunctional pelvic venous drainage and sometimes resecting vulvar, perineal and thigh varices. AIM: To assess the results of embolization of insufficient pelvic or ovarian veins on pelvic congestion syndrome. MATERIAL AND METHODS: Analysis of 17 female patients aged 32 to 53 years, who underwent subjected to a selective coil embolization of insufficient pelvic and/or ovarian veins through the jugular, basilic or cephalic veins. In the preoperative period, all patients had a lower extremity venous duplex pelvic ultrasound examination and some had an abdominal and pelvic CT angiogram. RESULTS: The technical success of the procedure was 100% and no complications were registered. During a 32 month follow up, no patient had symptoms of pelvic venous insufficiency or relapse of vulvar or thigh varices. CONCLUSIONS: Embolization of insufficient pelvic and ovarian veins is a safe and successful procedure for the treatment of pelvic venous insufficiency or vulvar varices.

OBJECTIVE: To investigate treatment-related outcomes, namely radiological clot resolution, post-thrombotic syndrome (PTS), and health related quality-of-life (HRQoL) scores, in children with Paget-Schroetter syndrome (PSS) undergoing multidisciplinary management, including anticoagulation and decompressive rib-resection surgery, with or without thrombolytic therapy. STUDY DESIGN: We identified all patients treated for PSS at our institution between the years 2010 and 2017. Baseline clinical and radiologic data were abstracted from medical records. Two validated survey instruments to quantify PTS and HRQoL were mailed to eligible patients. Standard statistical methods were used to summarize these measures. RESULTS: In total, 22 eligible patients were identified; 10 were treated with thrombolysis followed by anticoagulation and rib resection, and 12 were treated with anticoagulation and rib resection alone. Nineteen patients responded to the survey instruments. Median age at deep vein thrombosis diagnosis and survey completion were 16.3 and 20.4 years, respectively. Nineteen of 22 patients had thrombus resolution on radiologic follow-up. Fourteen of 19 survey respondents reported signs/symptoms of PTS of which the majority (12/14) reported mild PTS. Aggregate total, physical, and psychosocial HRQoL scores reported were 90.6, 96.7, and 93.3, respectively. Thrombolytic therapy was not associated with a significant improvement in radiologic, clinical or HRQoL outcomes. CONCLUSIONS: Most patients with PSS had complete thrombus resolution on imaging. Only 11% of survey respondents reported moderate PTS. The entire cohort reported excellent HRQoL scores. The role for thrombolytic therapy in the management of childhood PSS remains incompletely elucidated.
