Purpose: The detection of type II endoleak one month after endovascular aneurysm repair (EVAR) is usually neglected or considered benign. Aim of this report is to present a case of post-EVAR rupture, due to type II endoleak, and discuss on pathophysiology and differential diagnosis.

Case Report: We present a case of a 67-year-old male who was treated with EVAR for an asymptomatic abdominal aortic aneurysm and four months later, he presented with a contained rupture due to a type II endoleak.

Background: This review aims to collect all available data on early and late outcomes in patients undergoing fenestrated endovascular aortic aneurysm repair (F-EVAR) for pararenal or juxtarenal abdominal aortic aneurysms (AAAs).

Methods: The Pubmed, Embase, Scopus and Cochrane Library databases were systematically searched to identify eligible studies. Studies reporting at least early mortality after F-EVAR in patients with pararenal or juxtarenal AAA were included.

Dorsalis pedis artery (DPA) aneurysms are very rare and fewer than 60 cases have been reported in the literature. Most affected patients present with false aneurysms after orthopedic surgery or trauma. Here we report an unusual case of a giant DPA pseudoaneurysm after cannulation for arterial line placement in a patient newly diagnosed with systemic lupus erythematosus (SLE).

Objective: The aim of this study was to compare open and endovascular treatment of patients with subclavian artery atherosclerotic disease (SAAD) as far as early and late outcomes are concerned.

Methods: A systematic literature review conforming to established criteria was conducted to identify eligible articles published before January 2018. The following online search engines were used: PubMed, Embase, Scopus, and Cochrane Library (search conducted between December 2017 and January 2018).

Background: This meta-analysis aimed to evaluate randomized trials (RTs) that compare outcomes among asymptomatic patients with significant carotid stenosis undergoing carotid endarterectomy (CEA) versus carotid stenting (CAS) or best medical treatment (BMT).

Material And Methods: The Pubmed, Embase, Scopus and Cochrane Library databases were systematically searched to identify eligible studies. Data were analyzed by using the StatsDirect Statistical software (Version 2.

We report an unusual case of an 83-year-old man who was admitted with dizziness and repeated drop attacks. He was diagnosed with bilateral carotid artery occlusion and he underwent a left subclavian to left carotid bypass with ringed polytetrafluoroethylene graft. The patient's postoperative course was uneventful and no symptoms presented during a 6-month follow-up.

The incidence of combined neurovascular injuries among patients with high-energy shoulder trauma ranges from 27% to 44%. However, the presentation of an axillary artery pseudoaneurysm (PSA) due to shoulder dislocation without an associated osseous fracture is a very rare condition. Moreover, treatment of combined neurologic and vascular injuries of the shoulder remains controversial.

Objectives Low-molecular-weight heparins are recommended in the treatment of superficial vein thrombosis but with low grade of evidence. This study was conducted to assess the treatment outcomes of acute superficial vein thrombosis with intermediate dose of Tinzaparin. Methods Retrospective analysis of records from outpatients over a period of 16 months treated in seven centers with Tinzaparin 0.

Chronic totally thrombosed abdominal aortic aneurysms (AAAs) comprise a rare medical situation, with only a few cases reported in literature. Optimal management has been controversial, although an early risk for rupture is present. Therefore, we present a rare case of late rupture in a patient with a totally thrombosed AAA, and we discuss proper treatment.

Background: Proper management of patients with thromboangiitis obliterans (TAO) or cannabis-associated arteritis (CAA), presenting with critical lower limb ischaemia (CLI) remains controversial, and data are limited.

Patients And Methods: Patients with TAO or CAA presenting with CLI between 2011 and 2016 were retrospectively evaluated. Patients requiring primary intervention were excluded.

Peripheral artery disease (PAD) has been associated with severe morbidity and mortality worldwide, affecting the quality of life for millions of patients. Acute thrombosis has been identified as a major complication of PAD, with proper management including both open as well as endovascular techniques. Thrombolysis has emerged as a reasonable option in the last decades to treat such patients although data produced by randomized trials have been limited.

This report aims to present an unusual case with isolated bilaterally located internal iliac artery aneurysms (IIAAs) that were incidentally detected. Owing to the high surgical risk of the patient and anatomical location of the aneurysms, an endovascular management was preferred. Initially, the patient underwent a percutaneous embolization of the right-sided aneurysm with coiling.

A 75-year-old patient with severe comorbidities was treated with an Endurant (Medtronic, USA) II endograft due to a ruptured abdominal aortic aneurysm (AAA). After four years of unremarkable follow-up, bilateral limb separation was detected. The patient underwent endovascular bridging without any complication.

Leiomyosarcoma is an aggressive soft tissue sarcoma derived from smooth muscle cells. Of all soft tissue sarcomas, approximately 5-10% are leiomyosarcomas. Vascular leiomyosarcoma constitutes about 2% of all leiomyosarcomas and involves veins 5 times more than arteries.

Background: Aim of this study is to present the experience of an urban trauma center concerning the management of vascular trauma.

Methods: All data on major arterial injuries of the extremities treated during a 6-year period (August 2008 - August 2014) were retrospectively collected and analyzed. All cases were classified into iatrogenic and non-iatrogenic injuries, and comparisons were made between the two groups.

Arterial stenting has been broadly utilized for the management of peripheral arterial occlusive disease. The evolution of stent materials has led to the introduction of newer bioabsorbable scaffolds that have been extensively evaluated in the treatment of coronary artery disease. However, the utilization of bioabsorbable stents in the lower extremities remains challenging and has not been evaluated in the same degree.

Background: Carotid chemodectomas or carotid body tumors are rare neoplasms, generally benign and frequently asymptomatic, which represent 0.6 % of all head and neck tumours. Schwannomas or neurilemmomas are benign, slow growing tumours that derive from the sheath of peripheral and cranial nerves.

Osteochondromas are the most common benign bone tumors. Vascular complications are unusual, with false arterial aneurysms being the majority among them. Although there are several reports of false aneurysms because of an exostosis in the femoro-popliteal region, cases presenting with a false aneurysm of the brachial artery are quite rare.

Systemic lupus erythematosus (SLE) is a chronic inflammatory multisystemic disease, which affects primarily small-sized vessels, arterioles, venules, and capillaries in the cardiovascular system. Less often, medium-sized vessels are affected, and large-sized vessels are affected rarely. We report an unusual case of a 52-year-old female patient with SLE under treatment and multileveled arterial obstructive disease of the lower limb, who presented with critical limb ischemia.
