The idea of early endovascular aortic repair (EVAR) of "small" abdominal aortic aneurysms (AAAs) has gained attention over "watchful waiting," mostly due to the concern for losing the anatomic suitability for endovascular repair over time. Generally, small AAAs have longer, smaller, less angulated necks, and less tortuous iliac arteries than ...

Osteogenesis imperfecta (OI) is an inherited connective tissue disorder with skeletal dysplasia of varying severity, predominantly caused by mutations in the collagen I genes (COL1A1/COL1A2). Extraskeletal findings such as cardiac and pulmonary complications are generally considered to be significant secondary features. Aga2, a murine model for human OI, was systemically ...

BACKGROUND: Traditionally, single subcortical infarction has been considered to be caused by lipohyalinosis of small perforating arteries. However, atherosclerosis in the parental artery produces similar single subcortical infarction by blocking the orifice of branching arteries. The purpose of this paper is to review the evolving concepts, clinical characteristics, and classification ...

BACKGROUND: The technique of pancreatoduodenectomy (PD) has evolved. Previously, non-resectability was determined by involvement of the portal vein-superior mesenteric vein. Because venous resection can be achieved safely and with greater awareness of the prognostic significance of the status of the posteromedial resection margin, non-resectability is now determined by involvement of ...

BACKGROUND: Management of high-risk peptic ulcer bleeding (PUB) consists in a high-dose infusion of proton pump inhibitors (PPIs) with double endoscopic treatment. If bleeding recurs, a second endoscopic treatment is required. Surgical management should be performed in case of endoscopic treatment failure, or if a second rebleeding occurs. Arterial embolization ...

Object The small size and tortuous anatomy of intracranial arteries require that flow-diverter stents in the intracranial vasculature have a low profile, high flexibility, and excellent trackability. However, these features limit the degree of radiopacity that can be incorporated into the stents. Visualization of these stents and the degree of ...

IntroductionDual antiplatelet therapy (DAPT) with aspirin and a thienopyridine (eg, clopidogrel) prevents stent related thromboembolic events in cardiac patients and is frequently utilized during neurointerventional surgery. However, recent data suggest that many patients exhibit clopidogrel resistance. Prasugrel-a newer thienopyridine-lowers the rate of cardiac stent thromboses in clopidogrel non-responders but a ...
