Официальное название

Feasibility, Safety, and Clinical Outcomes of Endovascular Treatment of Thoracoabdominal Aortic Aneurysms and Aortic Arch Aneurysms Using Fenestrated and Branched Stent Grafts

Обзор

Prospective, nonrandomized, single-center, two-arm study to assess the feasibility and safety and to evaluate clinical outcomes of endovascular repair of complex aortic aneurysms (thoracoabdominal aortic aneurysms and aortic arch aneurysms) in patients at high risk for open surgery.

Подробное описание

To assess the feasibility and safety and to evaluate clinical outcomes of endovascular repair of complex aortic aneurysms (thoracoabdominal aortic aneurysms and aortic arch aneurysms) in patients at high risk for open surgery in two study arms:

1. TAAA (thoracoabdominal aortic aneurysm) Study Arm: To assess the feasibility and safety and to evaluate clinical outcomes of endovascular stent graft implantation using either a multibranched stent graft (Off-the-Shelf TAAA Device) or custom-manufactured physician-specified branched and/or fenestrated stent graft (Physician-Specified TAAA Device) to treat aortic aneurysms involving the mesenteric and/or renal arteries (TAAA) in patients at high risk for open surgery. 2. Aortic Arch Study Arm: To assess the feasibility and safety and to evaluate clinical outcomes of endovascular stent graft implantation using 1) physician-specified aortic arch stent graft device with up to 3 antegrade and/or retrograde branches or 2) a physician-specified retrograde left subclavian branch stent-graft with double or triple wide scallop to the left common carotid artery\] to treat aortic aneurysms involving the aortic arch in patients at high risk for open surgery.

• Устройство Endovascular treatment of Thoracoabdominal Aortic Aneurysm
  A TAAA is an abnormal enlargement (ballooning out) of the main artery (the aorta) and involves all or part of the aorta in your chest as well as all or part of the aorta in the abdomen. It also involves the part of the aorta where the arteries that bring blood to the liver, stomach and intestines and kidneys are attached. This investigational procedure that is being studied uses stent-grafts (cylindrical fabric tubes (grafts), with metal springs (stents) attached). The stent-grafts are placed i
• Устройство Endovascular treatment of Aortic Arch Aneurysms
  An aortic arch aneurysm is an abnormal enlargement (ballooning out) of the main artery (the aorta). The ascending aorta and aortic arch is the first part of the vessel as it exits the heart and makes a turn around the area of the collar bone. This part of the aorta gives branches that supply the head, brain and arms. The arch branch endovascular graft includes the main aortic arch portion and one to three cuffs (side branches) that allow the graft to be located in the aortic arch. The number of
