PURPOSE To study mid-term outcomes in patients admitted to receive treatment for acute type B aortic dissection. METHODS The study group comprised 229 patients with acute type B aortic dissection treated between January 2000 and July 2010. 128 patients had a thrombosed false lumen, and 101 had a patent false lumen. RESULTS In the thrombosed group, 6 had rupture, 4 had malperfusion, and 118 ...

BACKGROUND AND PURPOSE Stent-assisted endovascular treatment and flow diversion techniques are increasingly used for the management of wide-neck intracranial aneurysms. We report our initial clinical experience using a new flow diversion technique for the endovascular management of bifurcation aneurysms. MATERIALS AND METHODS Eight bifurcation aneurysms were treated by placing 2 stents in Y-c...

BACKGROUND Native arteriovenous fistula is one of the important routes for hemodialysis patients because of increased long-term survival and preservation of quality of life. We reported on a single-center experience with using pharmacomechanical thrombolysis for the treatment of thrombosed native arteriovenous fistula. MATERIAL/METHODS This was a retrospective study of 12 hemodialysis patient...

A patient with a spontaneously thrombosed arteriovenous malformation (AVM) presented with epilepsy. The CT and MRI appearances were of an intrinsic cerebral neoplasm with extensive surrounding vasogenic cerebral oedema and a mass effect. Histopathology confirmed a large thrombosed AVM. The natural history of AVMs and spontaneous thrombosis are reviewed.

BACKGROUND AND PURPOSE Destruction of microbubbles by transcutaneous low-frequency ultrasound (LFUS) has been used to lyse adjacent clot and recanalize acutely thrombosed vessels. LFUS with intraarterial microbubbles has been shown to lyse cerebral clot rapidly in pigs without thrombolytic drugs. We hypothesized that intravenous platelet-targeted microbubbles with LFUS may be a rapid noninvasiv...

A 42-year-old male was hospitalized with acute-onset aphasia and right hemiparesis due to acute middle cerebral artery (MCA) superior division infarction. A computerized tomography angiography (CTA), obtained for evaluation of stroke etiology and vessel status, revealed a partially thrombosed unruptured saccular aneurysm on left MCA bifurcation (figure a, b). Following fractional Figure:CT angi...

PURPOSE To assess the feasibility of combining stent implantation in the parent artery with endosaccular coil placement for the treatment of experimentally created wide-necked aneurysms. METHODS Wide-necked aneurysms were surgically created on the common carotid artery in 12 swine. A metal stent was endovascularly implanted across each aneurysm neck and its effect documented anigiographically...

BACKGROUND Technical problems such as graft and vascular size are more common in living donor liver transplantation (LDLT) than in deceased donor liver transplantation. It is usually possible to get enough length of vessels on the graft, but the opposite situation is devastating. Finding the suitable vessel graft is life-saving in those situations. In this paper we present a case of gonodal vei...
