Aortic rupture is a rare but potentially catastrophic complication following a balloon aortoplasty for recoarctation. The treatment of aortic ruptures remains challenging. We present here a 9-year-old girl with Turner syndrome who experienced a life-threatening rupture in her aorta after a balloon aortoplasty for recoarctation. She was successfully rescued by ...

Congenital cerebral vascular anomalies include a spectrum of conditions that result from perturbation of normal developmental processes. Although some of these conditions are asymptomatic and well compensated by collateral circulation, others can cause significant morbidity or produce a range of complications for affected patients. Knowledge of the underlying developmental etiologies ...

Background Brain arteriovenous malformations are vascular lesions that are increasingly being treated with endovascular embolization. A potential complication with endovascular embolization is microcatheter entrapment within the embolic material. In the present report, a novel technique for the retrieval of microcatheters retained during Onyx embolization of intracranial lesions is described. Clinical ...

Aneurysms that develop in arteriovenous accesses as a result of repeated punctures are sometimes complicated by infection or ischemia causing sloughing of the overlying skin, which may endanger the access and risk major bleeding and other complications. Surgical revision may necessitate the temporary use of a central venous catheter until ...

Acute dissection of the ascending aorta is a rare complication of percutaneous coronary intervention (PCI). Its mechanism involves disruption of the coronary intima by mechanical trauma, followed by subintimal injection of contrast, which, in turn, contributes to subsequent extension of the dissection. In contrast to spontaneous aortic dissection of ascending ...

Balloon angioplasty maturation is emerging as an important method to increase utilization and improve function of autogenous arteriovenous hemodialysis accesses (AVFs). Through the sequential dilation of small veins, large-diameter AVFs can be created with the inherent benefits of easier cannulation, greater overall surface area, improved patency, and fewer complications. A ...

Cystic adventitial disease is rare, but it is one of the well-recognized causes of non-atherosclerotic arterial stenosis or obstruction. Despite one of its most common symptoms being chronic intermittent claudication, it may be misdiagnosed as arterial embolism when presented with acute ischemic symptoms. Surgical resection is recommended because of recurrence ...

Endovascular stent grafting has emerged as an effective method for the treatment of complicated acute type B aortic dissections. In cases where access to the aorta cannot be established through the ileofemoral trunks, the axillary arteries are used as an alternative route. Often, however, these arteries are too small to ...

Stent-graft infections after endovascular aneurysm repair are rare but can have devastating consequences. Open surgery to treat such infections is associated with considerable morbidity and mortality. Removal of the stent-graft is technically challenging, especially when it has a suprarenal fixation. Several in situ reconstructions have been described, with varying results. ...

BACKGROUND: Aneurysms of the visceral branches of the abdominal aorta are uncommon and potential life-threatening entities. Although hepatic and splenic artery aneurysms have the highest prevalence among splanchnic aneurysms, superior mesenteric artery aneurysms are even more uncommon. For ruptured visceral arteries aneurysms, a mortality rate of between 20% and 100% ...
