Spontaneous dissections of multiple visceral arteries: an extremely rare case.

Spontaneous dissections of visceral arteries without aortic involvement are very rare. The etiologies of these entities are unclear and their clinical managements remain controversial. We report a case of spontaneous multiple dissections affecting 4 visceral arteries including the superior mesenteric artery, the celiac artery and the bilateral renal arteries.

Can Pre-Retrieval Computed Tomography Predict the Difficult Removal of an Implementing an Inferior Vena Cava Filter?

Purpose: Implementing an inferior vena cava (IVC) filter is a relatively safe procedure but potential negative long-term effects. The complications for filter retrieval have been noted. We examined filter characteristics on pre-retrieval computed tomography (CT) that were associated with complicated retrieval (CR) of IVC filters.

Platelet count evolution as a predictor of outcome after splenectomy for immune thrombocytopenic purpura.

Splenectomy is the definitive second-line therapy for refractory immune thrombocytopenic purpura (ITP), and has a reported response rate of 50-80%. Medical attention should be reconsidered when there is no evidence of accessory spleen in refractory ITP patients after splenectomy. The purpose of this study was to determine whether platelet count evolution differs between patients with a successful or unsuccessful result after splenectomy for ITP.

Mechanical thromboprophylaxis is sufficient to prevent the lower extremity deep vein thrombosis after kidney transplantation.

Purpose: Deep vein thrombosis (DVT) is a severe and common complication that occurs after the major operation. Despite the commonality of DVT there is limited data on the incidence of DVT after kidney transplantation (KT).

Mechanical thrombectomy with Trerotola compared with catheter-directed thrombolysis for treatment of acute iliofemoral deep vein thrombosis.

Background: Mechanical thrombectomy (MT) of acute deep vein thrombosis (DVT) is safe and effective in reducing thrombus burden. MT utilizing a percutaneous thrombectomy device confers a great advantage because it may reduce both the dose of the thrombolytic agent and the overall procedure time compared with a conventional catheter-directed thrombolysis (CDT). We examined the results of MT using the Trerotola device and evaluated factors affecting patient outcome.
