Aneurysms of the portal vein and its branches have been rarely described. Their natural history is unknown although large ones (>3 cm in diameter) have been reported to cause rupture, thrombosis, duodenal or biliary obstruction, inferior vena cava compression and/or portal hypertension. We report the case of an incidentally diagnosed 4.5 cm splenic vein aneurysm repaired by endovascular treatment through a transhepatic route. The aneurysm was successfully excluded using a covered stent (Viabahn, Gore). The transhepatic route opens the possibility of offering a minimally invasive approach to vascular lesions of the portal vein system.

Introduction In 1934 von Rosen first described a posttraumatic thrombosis of the distal ulnar artery resulting from blunt a trauma to the hypothenar region. But it was Conn in 1970 who named it the hypothenar hammer syndrome (HHS) 1-2 .

In the last 20 years, endovascular procedures have radically altered the treatment of diseases of the aorta. The objective of endovascular treatment of dissections is to close the entry point to redirect blood flow toward the true lumen, thereby achieving thrombosis of the false lumen. In extensive chronic dissections that have evolved with the formation of a large aneurysm, the dissection is maintained from the end of the endoprosthesis due to multiple orifices, or reentries, that communicate with the lumens. In addition, one of the primary limitations of this technique is when the visceral arteries have disease involvement. In this report we present a case where, despite having treated the entire length of the descending thoracic aorta, the dissection was maintained distally, leading to progression of the diameter of the aneurysm. After reviewing the literature, and to the best of our knowledge, we describe the first case in which renal autotransplant was performed to allow for subsequent exclusion of the aorta at the thoracoabdominal level using a fenestrated endoprosthesis for the celiac trunk and the superior mesenteric artery.

Arterial prosthetic graft infection is one of the most challenging issues in vascular surgery. We report a case of an infected descending thoracic aorta endograft, presenting itself several years after placement, with hemoptysis and back pain as referred symptoms. The patient was successfully treated by removing the thoracic aorta and replacing the infected endografts with a cryopreserved aortic allograft, running from the left subclavian artery to the aortic diaphragmatic hiatus.
