Anaplastic thyroid tumor as an embolic source of metastasis.

Tumor-based arterial thromboembolism in patients with cancer is a poorly described concept that lacks evidence for surgical indications owing to its unusual occurrence. The study and understanding of this condition's etiology is, however, essential because it could constitute the initial presentation or determine the prognosis of oncologic disease. In the present report, we have described the case of a 77-year-old female patient with multiple cerebral, splenic, and upper limb arterial embolic episodes.

Predictors of cervical bleeding after carotid endarterectomy.

Background: The aim of this study is to determine the incidence of severe cervical bleeding requiring reintervention after carotid endarterectomy (CEA), to identify its predictive parameters, and to find out the influence of these on major complications.

Methods: This was a retrospective review of 502 CEAs carried out in 455 consecutive patients between 1995-2011 in our institution. The end points were: postoperative cervical bleeding that required reoperation and major postoperative complications (i.

[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.

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.
