BACKGROUND Doxycycline can prevent aortic aneurysms through the inhibition of enzymes that degrade vessel walls. We investigated whether haemodialysis patients who had received one or more courses of doxycycline were at less risk for aneurysms in their vascular accesses than those who had received other antibiotics. METHODS Three hundred and eight patients undergoing chronic maintenance hemod...

Background Vascular anomaly and aneurysmal formation of an anterior communicating artery (Acom) complex has often been reported. Because of such a complicated relationship between the vascular structure and aneurysms, Acom aneurysm is one of the most difficult aneurysms to treat among other common anterior circulation aneurysms. We experienced an extremely rare and difficult-to-treat case of ru...

The common vascular anomalies of cerebral aneurysm and arteriovenous malformation may exist independently, or together as part of a closely related hemodynamic pairing. Resection or embolization of an AVM may be followed by a decrease in local blood flow, and lead to regression of a suitably situated proximal aneurysm. However, aneurysms located outside the angioarchitecture of the AVM, which r...

In this study, the case of a 46-year-old female patient with localized aortic root dissection and a superior mesenteric artery (SMA) aneurysm is described. Computed tomographic angiography could not clearly delineate an intimal flap in the aortic root, but it detected SMA aneurysm, which implied the presence of a vulnerability of the aortic wall. Finally, transesophageal echocardiography (TEE) ...

OBJECTIVE To examine the postoperative complications and death rate of major elective vascular surgery procedures in patients with end-stage renal disease (ESRD). BACKGROUND DATA Patients with ESRD undergoing elective major vascular surgical procedures are thought to have a high rate of postoperative complications and death. METHODS The American College of Surgeons-National Surgical Quality...

Endovascular aneurysm repair is a new and minimally invasive repair for patients with abdominal aortic aneurysm (AAA). This method has potential advantages that are incomparable with other repair methods. However, the enlargement of aneurysm in the absence of endoleak, which is known as endotension, may occur as one of post-operative compliances of this method. Typically, endotension is mainly ...

is a catastrophic complication of endo− vascular graft placement [1]. The typical symptom of secondary AEF is massive gastrointestinal bleeding with a history of thoracic aortic aneurysm repair [2]. En− doscopy is the most sensitive and specific diagnostic study [3]. Endoscopy should be carefully performed, as it excludes other, more common causes of upper gas− trointestinal bleeding, but shoul...

Recent technological advances in the diagnosis and therapy of abdominal aortic aneurysm and renovascular disease are continuing to bring about changes in the way patients suffering from these conditions are treated. The prevalence of both these conditions is increasing. This is due to greater life-expectancy in patients with arteriosclerosis, a pathogenetic factor underlying both conditions. Th...

1. An experimental study in rodents evaluated the long-term results of nanofibrous bioabsorbable polycarbonate urethane (dPCU) graft implantation for small diameter vessel replacement. Which following is true according to this study?1A.Anti-inflammatory signalling downregulated with dPCU grafts.B.dPCU grafts have inferior patency compared PTFE grafts.C.dPCU are prone aneurysm formationD.dPCU sh...

Objective: During cerebral aneurysm embolization using intracranial stents, platelet aggregation increases owing to increased wall shear stress and a loss of vascular endothelial function at the stent implantation site. Preoperative multiple antiplatelet therapy was introduced prevent severe thromboembolic complications due aggregation. However, specific guidelines for administration pharmacolo...
