Left Brachiocephalic Vein Stenosis due to the Insertion of a Temporal Right Subclavian Hemodialysis Catheter.

Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma.

Spontaneous rupture of a giant renal angiomyolipoma-Wunderlich's syndrome: Report of a case.

Introduction: Herein we present a rare case of pontaneous rupture of a giant renal angiomyolipoma (AML), with symptoms of hypovolemic shock (Wunderlich's syndrome), which was managed by urgent total nephrectomy.

Presentation Of Case: A 53 year old female was transferred to the emergency room with progressive acute painful swelling of the left lateral abdominal area, duration of 5h. An emergent ultrasonic examination, revealed a heterogeneous-solid mass with maximum diameter of 23cm, with probable origin from the left kidney.

Giant extra gastrointestinal stromal tumor of lesser omentum obscuring the diagnosis of a choloperitoneum.

Introduction: Herein we present an extremely rare case of a giant extra gastrointestinal stromal tumor (EGIST) of the lesser omentum obscuring the diagnosis of a choloperitoneum.

Presentation Of Case: A 79 years old female was admitted to our hospital with symptoms of vomiting and epigastric pain. Abdominal computer tomography revealed a sizable formation that was diagnosed as a tumor of the pancreas.

Unusual malpositioning of hemodialysis catheter into the hepatic veins.

Malpositioning of long-term hemodialysis catheter is a known complication that may lead to a gradual decline in blood flow. We report two rare catheter malpositions in the hepatic veins in two patients with end-stage renal disease in whom a dialysis catheter was inserted through the left external jugular vein and the right external jugular vein. Because of gradual reduction of catheters' blood flow, an angiography was performed, which confirmed catheters' tip positioning into the hepatic veins.
