|Complex Aortic Aneurysms Thoracoabdominal Aneurysms Pararenal Aneurysms Juxtarenal Aneurysms||Device: Physician modified stent graft||Not Applicable|
Endovascular repair of complex aortic aneurysms is limited by the need to maintain blood flow to the critical organs that receive blood from the aorta, such as the kidneys, liver and intestines. While there are some commercially available devices that may treat some of these patients these devices may not be suitable or available for a given patient. In this study we will use custom made devices manufactured by Cook, Inc, Zenith t-Branch devices and off-the-shelf, FDA approved devices which are altered by creating fenestrations (holes) in the stent graft that allow additional stents to be inserted into the blood vessels that supply blood to these critical organs.
Determination of which type of endograft to use will be based on the patient's anatomy and the perceived urgency of the need for repair. This decision will be made by the study team and confirmed by a 3rd party reviewer who is not an investigator on the study team. After ensuring that a patient meets inclusion and exclusion criteria for participation in the CARPE-CMD study, the perceived urgency for repair will be evaluated given the 8-10 week required time for manufacture of a CMD device.
If the patient's aneurysm is not symptomatic and if, at the discretion of the treating surgeon, the patient is deemed safe to wait 8 weeks until repair, the patient will be considered non-urgent. Non-urgent patients will undergo repair with a CMD device.
If the patient's aneurysm is symptomatic and if, at the discretion of the treating surgeon, the patient is deemed unsafe to wait 8 weeks until repair, the patient will be considered urgent. Urgent patients will undergo repair with a t-branch device (if anatomy suitable) if they are deemed safe to wait for the device to be obtained (<72 hours). Urgent patients who do not have anatomy suitable to a t-branch device or patients who are not deemed safe to wait for the device to be obtained, will undergo repair with a physician modified device.
The device is inserted into the body through two small punctures or incisions in the groin. Small stents will be inserted through the stent graft fenestrations into the major blood vessels affected by the aneurysm so that blood flow is maintained to these organs.

Experimental: Endovascular repair
Endovascular repair of Complex Aortic Aneurysm using a physician modified stent graft
Device: Physician modified stent graft
The surgeon will modify commercially available stent grafts to match the anatomy of the patient being treated. Small fenestrations (holes) will be made in the stent graft so that additional stents can be inserted through the fenestration and into the blood vessels that lead to the kidneys, intestines or liver. These stents allow blood to flow freely to these organs. This surgery is done through small incisions in the groin.
- The effectiveness of physician modified endovascular grafts will be determined by evaluating the proportion of patients that achieve Treatment Success [ Time Frame: 12 months post procedure ]Treatment success is a combination of technical success, and freedom at 12 months from the following: Type 1 and 3 Endoleaks, Stent migration of more than 10 mm, aortic aneurysm enlargement sac enlargement of more than 5 mm, aneurysm rupture and conversion to open repair.
- Incidence of Major Adverse Events [ Time Frame: Within 30 days of the initial procedure ]Major adverse events include death, myocardial infarction, stroke, respiratory failure, paralysis, bowel ischemia, and procedural blood loss of greater than 1 liter.
