RESUMEN
BACKGROUND: Hemorrhoidal artery embolization (Emborrhoid) is a novel method for the treatment of severe hemorrhoidal bleeding. Despite having a technical success rate of 93%-100%, the clinical success ranges between 63% and 94%, with a rebleeding rate of 13.6%. AIM: To evaluate the effectiveness of this procedure in reducing hemorrhoidal flow and hemorrhoidal bleeding. METHODS: This prospective observational pilot study was conducted at Division of General Surgery 1 and Tertiary Referral Pelvic Floor Center, Treviso Regional Hospital, Italy. In a 2 months period (February-March 2022), consecutive patients with hemorrhoidal bleeding scores (HBSs) ≥ 4, Goligher scores of II or III, failure of non-operative management, and a candidate for Emborrhoid were included. Endoanal ultrasound with eco-Doppler was performed preoperatively and 1 month after the procedure. The primary endpoint was to quantify the changes in arterial hemorrhoidal flow after treatment. The secondary endpoint was to evaluate the correlation between the flow changes and the HBS. RESULTS: Eleven patients underwent Emborrhoid. The overall pretreatment mean systolic peak (MSP) was 14.66 cm/s. The highest MSP values were found in the anterior left lateral (17.82 cm/s at 1 o'clock and 15.88 cm/s at 3 o'clock) and in the posterior right lateral (14.62 cm/s at 7 o'clock and 16.71 cm/s at 9 o'clock) quadrants of the anal canal. After treatment, the overall MSP values were significantly reduced (P = 0.008) although the correlation between MSP and HBS changes was weak (P = 0.570). A statistical difference was found between distal embolization compared with proximal embolization (P = 0.047). However, the coil landing zone was not related to symptoms improvement (P = 1.000). A significant difference in MSP changes was also reported between patients with type 1 and type 2 superior rectal artery (SRA) anatomy (P = 0.040). No relationship between hemorrhoidal grades (P = 1.000), SRA anatomy (P = 1.000) and treatment outcomes was found. CONCLUSION: The preliminary findings of this pilot study confirm that Emborrhoid was effective in reducing the arterial hemorrhoidal flow in hemorrhoidal disease. However, the correlation between the post-operative MSP and HBS changes was weak. Hemorrhoidal grade, SRA anatomy and type of embolization were not related to treatment outcomes.

BACKGROUND: The aim of the study was to evaluate the short-term and mid-term technical and clinical outcomes of the Bolton Treo endograft in subjects with abdominal aortic aneurysm (AAA) requiring endovascular aortic repair (EVAR) and assess if presence of hostile proximal neck would represent a risk factor for increased failure rates. METHODS: A retrospective review of all consecutive patients who had undergone elective or non-elective EVAR with the Bolton Treo endograft at 5 institutions located in the North-East of Italy (January 2016-December 2020) was performed. The main exposure variable for this study was presence of hostile (HAN) or friendly (FAN) aortic neck. RESULTS: A total of 137 consecutive patients were treated with the Bolton Treo endograft at participating institutions; of these 63 (46%) presented HAN while 74 (54%) had FAN. At baseline, no significant differences were observed in the distribution of demographics and comorbidities between study groups. Two type Ia endoleaks (EL) were detected at completion angiography, all in patients with HAN but none in patients with FAN (3% vs. 0%, P = 0.04), but no type III EL were identified in the whole cohort. The median duration of follow-up in the study cohort was 30 months (IQR 22-34 months) and was similar between study groups (P = 0.87). At 3-years, survival estimates were 89% and 91% (P= 0.82) in patients with HAN and FAN, respectively. At three years, patients with HAN had significantly lower freedom from type IA endoleak as compared with patients with FAN (87% vs. 94%, P= 0.02). No significant differences were found between study groups in the three-year estimates of freedom from reinterventions (80% vs. 86%, P= 0.28). Using cox proportional hazards, presence of type II EL (HR 3.15, 95%CI 1.18-8.5, P= 0.02) and presence of type IA EL (HR 4.22, 95%CI 1.39-12.85, P= 0.01) were found as independent predictors for reinterventions in univariate analysis, although they were no longer significant in the multivariate model. Freedom from sac increase >5mm at three years were not significantly different between study groups (92% vs 91%, P= 0.95). CONCLUSIONS: Within a contemporary multicentric real-world experience, EVAR with the Bolton Treo endograft shows a satisfactory safety profile in the immediate postoperative phase and acceptable outcomes during mid-term follow-up. Presence of HAN is correlated with development of type Ia EL (either early following stent-graft implantation or late after EVAR) which, in turn, may represent a significant factor leading to reinterventions.

PURPOSE: To assess the technical and clinical success rates of superior rectal artery embolization in the treatment of symptomatic Grades 2 and 3 hemorrhoidal disease. MATERIALS AND METHODS: Since March 2019, 43 patients (24 men and 19 women; mean age, 52 years [18-77 years]) with symptomatic hemorrhoidal disease have been treated and completed the 6-month follow-up with anamnestic questionnaire and disease scores, including French bleeding, Goligher prolapse, visual analog scale for pain, and quality of life. Clinical success was assessed at 7 days, 1 month, and 6 months of follow-up by updating the clinical scores. Statistical analysis was performed using SPSS 25.0. RESULTS: In all, 25 patients had Grade 2 prolapse and 18 patients had Grade 3 prolapse, with 96% and 77%, respectively, having bleeding as a symptom. All patients were discharged within 24 hours. The reduction in the French bleeding score (global and single entity) in Grade 3 prolapse was statistically significant (P = .001). Improvement in the quality of life was significant in both groups (P < .05). No serious complications were registered. CONCLUSIONS: Hemorrhoidal embolization was a safe and effective technique in the treatment of symptomatic hemorrhoidal disease with minimal hospitalization, pain, and disruption of daily activities. It can be offered to patients unwilling to undergo a surgical procedure but can also be indicated in the emergency setting for patients on anticoagulant therapy or those unfit for surgery.

AIMS: Renal vascular malformations, congenital or acquired, are sometimes challenging for urologists and interventional radiologists to resolve. Arterovenous fistulas and pseudoaneuryms are usually embolized by interventional radiologists, with a low rate of complications. We propose a new endourological/interventional radiology technique to treat a source of arterovenous bleeding coming from a renal calyx in a minimally invasive way. METHODS: A combined endourological and interventional radiology procedure is described, using a Flexible Fiberoptic Ureteroscopes to undertake a retrograde intrarenal surgery (RIRS) to identify the source of bleeding; subsequently the VortX Coil® is inserted through a microcatheter to stop the bleeding and the correct position of the VortX coil is evaluated. Furthermore, we made a literature research on Pubmed and Medline to look for similar procedures. RESULTS: In case of a renal bleeding that could not be treated by endovascular way, a combined urological and interventional radiology procedure can be undertaken. We did not find similar endourological and interventional radiology procedure on Pubmed and Medline, so this is the first tecnique of endourological closure of a bleeding point using a coil. CONCLUSION: From our experience this could be a mininvasive technique to solve renal bleedings coming from a calyx that are not found by endovascular approach. Indeed, in our knowledge, the technique here described is the first that provides the use of an endovascular coil by endourological way in renal vascular malformations.

Percutaneous ultrasound-guided renal biopsy (RB) is the gold standard for diagnosis of renal diseases. The standard procedure involves biopsy in the prone position (PP) for the native kidneys. In high risk patients, transjugular and laparoscopic RB have been proposed. In patients suffering from obesity or respiratory diseases, the RB of the native kidney in the supine anterolateral position (SALP) represents an alternative to these invasive and expensive methods. We illustrate the technique of execution of RB in the lateral position (LP) on native kidneys. The procedure is safe, effective and has reduced the path travelled by the needle biopsy compared with PP and SALP.

Goodpasture's disease (GD) is an uncommon and severe autoimmune disorder caused by circulating autoantibodies directed against the glomerular basement membrane cross-reacting with the alveolar basement membrane. GD is clinically characterized by rapidly progressive glomerulonephritis, often associated with pulmonary hemorrhage representing a nephrological emergency. We present the clinical features of 9 cases, diagnosed in 1997-2012, in our Renal Unit. Contrary to previous reports, we found a predominance of GD in females and we observed unusual clinical patterns, such as the association with renal vein thrombosis in a pregnant patient, thrombosis of the pulmonary arteries and a late isolated recurrence of alveolitis. In dialysis-dependent patients, renal transplantation can represent an available treatment option.

Uremia associated with anticoagulant therapy is a high risk factor for bleeding complications in patients undergoing hemodialysis. We report a case of intrarenal hematoma arising in a uremic patient treated with warfarin. The hematoma was rapidly diagnosed by ultrasonography of the abdomen and treated with embolization. Our experience confirms that the availability of an ultrasound facility within the renal unit allows better assessment of our patients, also in the management of the most fearsome and rare complications. Moreover, it strengthens the evidence that uremic patients are at high risk of bleeding complications when treated with oral anticoagulants.
