[Ischemic stroke due to paradoxical embolism through pulmonary arteriovenous malformation in a young patient].

Paradoxical embolism due to an isolated pulmonary arteriovenous malformation (PAVM) is a rare cause of ischemic stroke. PAVMs are abnormal high-flow connections between pulmonary arteries and veins, diverting deoxygenated blood into the systemic circulation and they represent a less common source of paradoxical embolisms, especially in young individuals. Endovascular embolization is the preferred treatment for clinically significant PAVMs.

Chronic abdominal aortic dissection, endovascular treatment using a new Stent-graft for in situ Fenestration.

Background: Although endovascular treatment of the thoracic aorta (TEVAR) has become an elective procedure for treatment of complicated type B aortic dissection, its role in treating post dissection thoraco-abdominal aortic aneurysm (TAAA), is still limited. This is a case of aortic vascular disease, which reports the use of a new endovascular device.

Case Presentation: We present the case of a 62 year old male patient with a history of hypertension, active smoker, who presented penetrating descending thoracic aortic ulcer in the setting of a chronic abdominal aortic dissection.

Left subclavian artery coverage during thoracic endovascular aortic aneurysm repair does not mandate revascularization.

Objective: This study assessed the risk of left subclavian artery (LSA) coverage and the role of revascularization in a large population of patients undergoing thoracic endovascular aortic aneurysm repair.

Methods: A retrospective multicenter review of 1189 patient records from 2000 to 2010 was performed. Major adverse events evaluated included cerebrovascular accident (CVA) and spinal cord ischemia (SCI).

Safety and feasibility of balloon-expandable stent implantation for the treatment of type I endoleaks following endovascular aortic abdominal aneurysm repair.

Aims: The occurrence of type I endoleaks represent an ominous sign after endovascular aneurysms repair (EVAR). We report our experience using balloon-expandable stents (BES) for the treatment of proximal Type I endoleaks at five high-volume hospitals in Argentina.

Methods And Results: Of 1,395 patients who underwent EVAR, we retrospectively collected data of 29 (2%) consecutive patients who underwent additional BES to repair proximal type I endoleaks.

A branched, balloon-deployable, Aortomonoiliac stent-graft for treatment of AAA in a patient with a solitary intrapelvic kidney.

Purpose: To report the use of a branched, balloon-deployable stent-graft to treat abdominal aortic aneurysm (AAA) in the setting of a solitary kidney.

Case Report: A 72-year-old man with a solitary intrapelvic kidney and multiple comorbid conditions was diagnosed with an asymptomatic 5.3-cm abdominal aortic aneurysm (AAA); the renal artery emerged from the aneurysm sac.
