Multistage closure of a congenital extrahepatic portosystemic shunt.

Background: Congenital extrahepatic portosystemic shunts (CEPS) are rare shunts connecting the extrahepatic portal system with the inferior vena cava. Shunt dimensions and the risk of portal hypertension determines the closure strategy. Endovascular treatment is indicated for single stage occlusion of longer length shunts, whereas the remaining shunt types are preferentially surgically occluded.

External Iliac Artery Laceration Caused by Hip Prosthesis Migration.

Hip arthroplasty is a common and safe intervention in orthopedic surgery. However, the proximity of this joint to large vessels makes the occurrence of vascular injury a rare but serious and possibly lethal complication of this surgical technique. Acute vascular injuries in the context of a hip arthroplasty have variable etiologies and clinical presentations, and are more common in revision surgeries and in situations of medial intrapelvic migration and of chronic infection of the hip prosthesis.

Endovascular Removal of Foreign Bodies.

Introduction: Intravascular or catheter embolization of a foreign body, either by fracture or migration, is a rare condition, occurring in approximately 1%. This study is focused on the migration of catheters since they represent the majority of cases of embolization. We present one of the largest published series of removal of foreign bodies with endovascular techniques.

[The role of percutaneous renal fenestration in the management of acute aortic dissection. Case report].

Aortic dissection is one of the most feared vascular disease, coursing with high rate of complications. Depending on the location of the intimal tear, aortic dissection could implicate the ascending aorta, the heart and descending aorta, or only the descending aorta. The first case (type A) has absolute surgical indication.

Renal artery aneurysm: an endovascular treatment for a rare cause of hypertension.

Renal artery aneurysms are a rare cause of secondary hypertension. Endovascular treatment with a polytetrafluoroethylene (PTFE)-coated stent can exclude aneurysms and treat hypertension. We report the case of a 23-year-old man with hypertension diagnosed three years earlier and in whom renal angiography revealed three aneurysms involving the right renal artery.
