Could prior endovascular interventions affect the results of lower extremity below the knee autologous vein bypasses?

Background: Performing a non-selective primary endovascular approach involves risk of performing ineffective procedures and could compromise future treatments. The objective of this research is to determine if previous failed endovascular intervention could affect bypass results.

Methods: Retrospective cohort study including 77 below the knee (BTK) bypasses with great saphenous vein (GSV) in patients with critical limb ischemia, carried out between 2008-2018.

Development of an individualized scoring system to predict mid-term survival after carotid endarterectomy.

Background: Carotid endarterectomy (CEA) is a prophylactic surgery focused in preventing stroke in the mid-long term. The purpose of this study was to analyze mid-term mortality in patients undergoing CEA, identify predictors of 3-year mortality and design a score to estimate individual risk of mortality in this population.

Methods: A retrospective single-center study including consecutive patients undergoing CEA between 1997-2010.

Endograft-assisted coil embolization of a celiac trunk aneurysm.

Background: Celiac trunk aneurysms are rare but potential life-threatening lesions. Endovascular techniques are more often used for their treatment because of low rates of morbidity and mortality.

Case Report: We describe a modification of stent-assisted coil embolization technique more commonly used in the treatment of intracranial aneurysm, to exclude a 50-mm diameter celiac trunk aneurysm.

[Natural history of moderate-degree carotid stenosis in patients with peripheral artery disease].

Background And Objective: To understand the evolution of moderate asymptomatic carotid stenosis, the factors that influence its progression and the related morbimortality.

Patients And Methods: Retrospective observational study of 133 patients with asymptomatic carotid stenosis between 50-69% in one or both carotids between 2002 and 2009. Included patients were subjected to screening for peripheral arterial disease (PAD), aneurysmal disease or carotid bruit.

Endovascular repair of an iliac arteriovenous fistula secondary to perforation from a common iliac aneurysm in a patient with Ehler-Danlos syndrome.

Background: Type IV Ehler-Danlos syndrome (EDS) patients are prone to life-threatening vascular complications. Surgical management of those complications is challenging owing to vessel wall fragility, which may result in hemorrhagic events and high mortality rates. Here we report a case of left common iliac aneurysm perforation of the ipsilateral iliac vein repaired using endovascular technique in a patient with EDS.

Interaction of cerebrovascular disease and contralateral carotid occlusion in prediction of shunt insertion during carotid endarterectomy.

Introduction: To assess the possible role and the interaction of cerebrovascular disease and vascular stenosis on the necessity of shunt insertion during carotid endarterectomy (CEA).

Material And Methods: Eighty consecutive patients undergoing CEA under regional anaesthesia were prospectively enrolled. Patients were divided into two groups depending on whether they were shunted or not.

Primary aortoduodenal fistula in a patient with pararenal abdominal aortic aneurysm.

Primary aortoenteric fistula is a rare and extremely serious condition. In most cases, it is caused by an abdominal aortic aneurysm presenting with symptoms of gastrointestinal bleeding. Diagnosis is difficult owing to its rarity and the fact that diagnostic tests are not definitive in many cases.

Popliteal artery aneurysm in patient with Klippel--Trénaunay--Weber syndrome.

Background: The association of Klippel-Trénaunay-Weber syndrome (KTWS) with artery aneurysms is very rare.

Methods And Results: A 61-year-old man, diagnosed with left lower limb KTWS, presented with a venous ulcer and a popliteal aneurysm measuring 3.5 cm in diameter in the same limb.

Endovascular treatment of a ruptured iliac aneurysm previously excluded.

We report a case of an isolated ruptured iliac artery aneurysm that had previously been treated, 25 months before, with iliac endovascular exclusion. Urgent computed tomographic (CT) scan showed the retroperitoneal hematoma and a type IA endoleak. On an emergency basis, at the operating room, an aortouni-iliac graft and femorofemoral crossover bypass were performed, successfully.

Comparative analysis of renal function after treatment of infrarenal abdominal aortic aneurysms with a suprarenal fixation device as opposed to open surgery.

We analyzed the repercussions on renal function between suprarenal endograft fixation and open surgery in the treatment of infrarenal abdominal aortic aneurysms (IAAAs) and determined the influential factors. Between 1999 and 2005, 59 IAAAs were treated with elective OS and 56 with SEF. The serum creatinine (Cr) level and its clearance were determined before the procedure, in the intensive care unit (ICU), on discharge, and after 1, 6, 12, and 24 months.

[Clinical and therapeutic characteristics of limb emboli].

Introduction: To treat an extremity embolus seems to be a simple and safe procedure. However, it is not exempt from potentially serious complications. We review our experience of treating acute peripheral arterial occlusion due to emboli.

[Value of the Doppler-ultrasonography for the diagnosis of temporal arteritis].

Background And Objective: The aim of this study was to investigate the accuracy of color Doppler-ultrasonography (CDU) compared with biopsy for the diagnosis of temporal arteritis (TA).

Patients And Method: Twenty-three patients with suspected TA on the basis of clinical criteria were evaluated with CDU prior to temporal artery biopsy. The presence of a hypoechoic halo, suggesting edema of the inflamed vessel, and inflammatory stenoses were registered.

[Effect of renal revascularization techniques on renal function and blood pressure control].

Background And Objective: Our objective was to assess the effect of renal revascularization on renal function and blood pressure control.

Patients And Method: Retrospective analysis of primary renal revascularization procedures performed during a 6-year period. Parameters of renal function and blood pressure control were assessed before and after the procedure.
