RESUMEN

BACKGROUND: SARS-CoV-2 infection involves the phase of viral replication and inflammatory response predicting the severity of COVID-19. Vascular involvement in SARS-CoV-2 infection has been well established. Thrombotic complications are common, while only few cases of dilatative diseases have been reported. CASE REPORT: We herein report the case of a 65-year-old male patient with an inflammatory 25-mm saccular popliteal artery aneurysm detected six months after symptomatic COVID-19 (pneumonia, and pulmonary embolism). The popliteal aneurysm was surgically managed with aneurysmectomy, and reversed bifurcated vein graft. Histological examination detected the infiltration of monocytes and lymphoid cells into the arterial wall. CONCLUSIONS: Popliteal aneurysm could be related to inflammatory response related to SARS-CoV-2 infection. The aneurysmal disease should be considered mycotic and surgically managed without prosthetic grafts.

RESUMEN

OBJECTIVE: Extrapulmonary localization of tuberculosis accounts for about 15-20% of cases. Several cases of Mycobacterium tuberculosis with vascular involvement have been described, but only few cases for limb vessels. CASE REPORT: We report the case of a 33-year-old man from Gambia with a symptomatic pseudoaneurysm of the right superficial femoral artery. Total body positron emission tomography/computed tomography with [18F]FDG revealed an active infection. The patient underwent vascular reconstruction with a straight reversed vein graft. Molecular testing for Mycobacterium tuberculosis was non-diagnostic. Cultures of the pseudoaneurysm wall and thrombus removed during surgery grew Mycobacterium tuberculosis. CONCLUSIONS: The diagnosis of vascular tuberculosis infection due to Mycobacterium tuberculosis is a challenge. Epidemiology remains the primary criterion for maintaining a high index of suspicion.

RESUMEN

We report the case of a 72-year old man previously treated with an aortic endograft for an abdominal aortic aneurysm. After 3 years the patient developed a sepsis. Imaging and blood exams detected an endograft infection related to Listeria monocytogenes. Patients underwent endograft removal and in-situ aortic reconstruction with a cryopreserved allograft. A continuous antibacterial therapy has been established. One-month follow-up revealed the absence of clinically relevant infection with patency of the graft and absence of biochemical inflammatory markers.

RESUMEN

OBJECTIVE: Intravenous iloprost is an important option in the treatment of ischemic disease of the lower limbs; however, the administration of therapy is frequently compromised because of the need for long cycles of infusion in a hospital setting. The aim of the study is to evaluate the efficacy, safety, feasibility, and the economic impact of infusion therapy in the outpatient setting. PATIENTS AND METHODS: Twenty-four consecutive patients were treated with iloprost at their homes where they were administered a slow rate of infusion for 24 hours a day, during 9.9 ± 2.3 days, with a portable syringe pump (Infonde®). RESULTS: The clinical condition of patients evaluated with the modified SVS/ISCVS scale significantly improved after treatment (+1.29 ± 1.04 points vs. baseline, p<0.001). The drug was well tolerated; neither significant adverse events associated with medication nor problems related to venous access were recorded at home. Ninety-six percent of patients successfully completed the entire treatment cycle, and the evaluation questionnaire showed a high acceptance of the therapy. From the perspective of the hospital authority, lower direct medical costs were estimated for the domiciliary infusion process compared with the inpatient infusion setting. CONCLUSIONS: Treatment with iloprost in the outpatient setting is effective, safe, feasible, and more acceptable to patients than infusion at the hospital. In addition, it has a favorable economic and organizational impact on the medical ward.

RESUMEN

Focal stenosis or occlusion of the infrarenal aorta is a relatively rare entity. In particular, soft-plaque of atherothrombotic origin in the aortic segment is linked to high-risk for peripheral embolisation. To our knowledge, the present case report describes for first time in the literature successful percutaneous treatment of a symptomatic soft-plaque infrarenal aortic stenosis with severe calcification of the iliac vessels by stent-graft, in particular by the new Endurant. Endovascular exclusion of the thrombotic lesion by endoprosthesis covers the atherosclerotic wall treating the potential underlying cause of the thrombus formation. The radial force of the endoprosthesis seems to be sufficient achieving complete expansion. However, long-term results are warranted.

RESUMEN

AIM: Aim of this study was to retrospectively analyze the experience of a single center in the hybrid treatment of aortic arch aneurysms. METHODS: From January 2005 to August 2008 a hybrid treatment for complex aortic aneurysms (aortic arch, thoracoabdominal aorta or thoracic and abdominal segments at the same time) was performed in 34 patients. In 11 cases a hybrid exclusion of an aortic arch aneurysm was carried out. Perioperative results in terms of morbidity and mortality were assessed. Follow-up examination consisted of computed tomography scan and chest X-ray at discharge, 6 and 12 months, and yearly thereafter. Mid-term survival and graft-related complications were analyzed. RESULTS: All the patients were males with a mean age of 74 years, range 68-81. Intraoperative technical success was achieved in all the cases. At 30 days one patient died for an acute stroke. The overall 30-day mortality rate was 9.1%. One frenic nerve paralysis and one acute re-spiratory failure with pneumonia were observed with an overall 30-day major morbidity rate of 18.2%. During follow-up (mean duration 19.3 months, range 1-36) no death, reintervention, conversion, aneurysm-related complication or graft thrombosis were recorded. CONCLUSION: Hybrid approaches to the treatment of complex aortic lesions involving the arch can be successfully used. However, perioperative complications remain still not irrelevant and long-term efficacy has to be proved.

RESUMEN

AIM: The aim of this study was to evaluate the authors' experience in below-knee revascularization in patients with critical limb ischemia, comparing long-term outcomes in primary and secondary interventions. METHODS: From January 2000 to December 2006, 140 consecutive below-knee revascularizations in patients with critical limb ischemia were performed at the Department of Vascular Surgery of the University of Florence (Italy). In 105 patients (75%) a primary intervention was performed (Group 1). Early and long-term results in terms of survival, patency and limb salvage were compared with those obtained in the remaining 35 patients (25%) secondarily operated on in the same period for a late (>30 days) bypass graft thrombosis (Group 2). RESULTS: One patient died in the early postoperative period. Thirty-day thrombosis and amputation rates were poorer in Group 2 than in Group 1 (17.1% and 4.8%, P=0.02; 37.1% and 16.2%, P=0.01, respectively). Mean duration of follow-up was 25.1 months. At 60 months there were no differences between the two groups in terms of survival (90.1% in Group 1 and 90.9% in Group 2; P=NS), primary patency (43.5% in Group 1 and 31.9% in Group 2; P=NS) and secondary patency (48.4% in Group 1 vs 43.8% in Group 2; P=NS). Estimated 60-month limb salvage rate was significantly poorer in Group 2 than in Group 1 (64.1% and 77.7%, respectively; P=0.05). In Group 2 prosthetic graft material significantly affects 60-month limb salvage rate. CONCLUSION: Redo below-knee revascularization in patients with critical limb ischemia provides acceptable long-term results in terms of primary and secondary patency; however, limb salvage appeared to be slightly worse in patients undergone redo surgery.

RESUMEN

OBJECTIVES: The aim of the study was to evaluate early and mid-term results of surgical repair of isolated iliac artery aneurysm (IAA) in patients with non aneurysmal abdominal aorta. METHODS: From January 1996 to December 2006, 34 patients with IAA had elective surgery. In 32 cases open repair was performed. Two patients had endovascular repair using a tube endoprosthesis and internal iliac artery coil embolization. The diameters of the abdominal aorta and iliac arteries were measured preoperatively and during follow-up. Early and late results in terms of mortality, major morbidity, reinterventions and graft-related complications were recorded. Mean pre and postoperative diameters of abdominal aorta were compared. RESULTS: The site of the IAA was the common iliac artery in 29 cases (10 bilateral), internal iliac artery in 4 cases and external iliac artery in 1 case. Preoperative mean abdominal aortic diameter was 22.2mm (SD 7.6). There were no perioperative deaths and two major complications (retroperitoneal bleeding and limb ischemia) occurred. At the median follow-up time of 24 months survival was estimated as 91%. No reinterventions, graft thrombosis and graft related complications occurred. There were no cases of abdominal aorta aneurysm development. Mean aortic diameter at the most recent imaging was 23.1mm, which was not significantly different from preoperative values (p=0.2). CONCLUSIONS: Surgical treatment of IAAs provides good early and mid-term results. During mid-term follow-up the diameter of abdominal aorta remains stable, suggesting IAA may be a localized aneurysmal disease.

RESUMEN

OBJECTIVE: Intraoperative quality control after carotid endarterectomy (CEA) has been advocated to improve the results of surgical treatment of extracranial carotid artery disease. The aim of this study was to evaluate the usefulness of completion angiography (CA) in prevention of stroke and restenosis after CEA in a single center experience. MATERIALS AND METHODS: Data concerning 914 consecutive CEAs performed in 3 years (2000-2002) were prospectively collected in a dedicated database. Patients were divided into two groups: in the first group (mandatory-CA group; 430 cases) CA was routinely carried out, except in presence of contraindications to iodinate contrast agents; in the second group (selective-CA group, 484 cases) CA was performed only in selected cases, at surgeon's discretion. RESULTS: There were no significant differences between the two groups in terms of neurological complications at awakening (0.5% in mandatory-CA group and 0.4% in selective-CA group; p=n.s.) and in 30-day stroke and death rate (1.9% and 1.4%, respectively; p=n.s.). A surgical revision on the basis of CA findings was performed in 5 cases in mandatory-CA group and in 2 cases in selective-CA group (1.2% and 0.4%, respectively; p=n.s.). In the second group, the conditions significantly associated with the need for CA examination were internal carotid near-occlusion, preoperative symptoms, shunt insertion, kind of surgical reconstruction, redo surgery. Estimated absence of ipsilateral stroke and absence of restenosis at 18 months was 98.9% and 89.7% in mandatory-CA group and 99.3% and 93.4% in selective-CA group (p=n.s.) respectively. CONCLUSIONS: Based on our experience, routine CA following CEA is not suggested. A policy of selected CA at the surgeon's discretion seems to make the intervention safe and durable as well.

RESUMEN

Healthcare managers are demanding ever more flexible and sophisticated capabilities from their management information systems, without sacrificing software reliability. This is paradoxical, since, all things being equal, the number of bugs residing in a program is a function of how complex it is. One method of addressing the problem of software reliability is to focus on software testing tools and techniques within the framework of an effective Quality Assurance methodology. The purpose of this article is to discuss the integral role Quality Assurance plays in the software life cycle that forges the development of new and enhanced software. An in-depth discussion of the software life cycle is beyond the scope of this article; it will be discussed only in its relation to the role of Quality Assurance.
