Background & Importance: Our study was performed based on the first case, reported in English, of a patient with three contemporary lesions, an extra-axial malformation and two vascular ones. Case Presentation: A 62-year-old man referred to our clinic due to right hand tremor associated to a slowing of idea-forming function and movements. The neuroradiological evidence showed a right fronto-te...

PURPOSE The purpose of this study was to determine the impact of an endovascular stent-graft program on vascular training in open aortic aneurysm surgery. METHODS The institutional and vascular surgery fellow experience in aortic aneurysm repair during a 6-year period was reviewed. The 3-year period before introduction of endovascular repair was compared with the 3-year period after introduct...

Superior mesenteric artery aneurysms are rare and associated with high mortality rates in cases of rupture. Current Society for Vascular Surgery guidelines recommend treatment all superior regardless size. A 53-year-old woman who was admitted abdominal pain found a 14-cm, ruptured branch aneurysm. Endovascular approach performed microvascular plug embolization feeding aneurysm sac exclusion ste...

isolated third nerve palsy develops in numerous intracranial pathologies such as closed head trauma, tumor, and aneurysm. this report describes a 61 years old female with an abrasion on the left forehead and ptosis of the left eye. initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. high-resolution and multi-axial enhanced mag...

An 85-year-old man was found to have a 9 cm diameter true aneurysm of an obtuse marginal saphenous vein graft. The graft was fed by a relatively narrow neck from the proximal remnant of the obtuse marginal graft 10 years after prior coronary artery bypass graft surgery. An Amplatzer vascular plug was used successfully to occlude the neck of the aneurysm. Follow-up CT scan 1 month afterward demo...

acoma aneurysms are complicated and high incidence lesions. the successful treatment depends on understanding the anatomical location of aneurysm. the early surgery and selecting the superior method of surgery and post-operative cares affect the surgical outcomes of these patients. in this study 30 patients who were admitted to firoozgar hospital in a 3-year period (2001-2004), undergone surger...

INTRODUCTION Ultrasound can visualize and update the vessel status in real time during cerebral vascular surgery. We studied the depiction of parent vessels and aneurysms with a high-resolution 3D intraoperative ultrasound imaging system during aneurysm clipping using rotational digital subtraction angiography as a reference. METHODS We analyzed 3D intraoperative ultrasound in 39 patients wit...

abstract: introduction & objective: in patients with chronic renal failure who need chronic hemodialysis, av fistula is one of the most proper ways of vascular access. the aim of this study was to assess the patency and complications of av fistulas in patients with chronic hemodialysis. materials & methods: in this descriptive study 82 patients with chronic renal failure, who underwent av fistu...

Nitric oxide (NO) receptor soluble guanylyl cyclase (sGC) is a key regulator of several important vascular functions and is important for maintaining cardiovascular homeostasis and vascular plasticity. Diminished sGC expression and function contributes to pathogenesis of several cardiovascular diseases. However, the processes that control sGC expression in vascular tissue remain poorly understo...

Hereditary Haemorrhagic Telangiectasia (HHT) is an autosomal dominant disorder characterized by vascular dysplasia. Hepatic Vascular Malformations (VMs) range from small telangiectases to significant shunting. Here we report two cases of HHT. Case 1 had diffuse ectasia the hepatic artery along its intrahepatic and extrahepatic course with a arterial aneurysm. 2 presented ileal telangiectases. K...
