Challenges in Diagnosis of Non-A Non-B Acute Aortic Dissection.

Background: Non-A non-B (NANB) aortic dissections are uncommon and frequently unrecognized diseases. However, their proper identification is crucial given the unpredictable behavior of the dissected aorta with potential mortality and increased morbidity. We investigate the accuracy of radiological computed tomography angiography (CTA) reports in the diagnosis of acute NANB and the risk related to delayed recognition or misdiagnosis.

Type Ia endoleaks after fenestrated and branched endografts may lead to component instability and increased aortic mortality.

Objectives: Fenestrated and branched endografts allow for proximal sealing zone extension into or above the visceral aorta to optimize landing in healthy aorta. We describe the incidence, causes, and implications of proximal endoleak development in patients undergoing complex endovascular aortic aneurysm repair.

Methods: All patients undergoing a fenestrated/branched repair were entered onto a prospective database, and this analysis included all those with at least one postoperative contrast computed tomography scan.

A minimally invasive approach to the treatment of aberrant splenic artery aneurysms: a report of two cases.

Symptomatic aneurysms of an aberrant splenic artery originating from the superior mesenteric artery are rare, with only five previous reports in the literature. The retropancreatic position renders their treatment more complex than aneurysms of orthotopic splenic arteries. Traditional treatment has been open surgical repair, with or without maintenance of flow through the splenic artery.
