Detailed Description
Aortic disease is the direct cause of close to 10000 deaths annually in the United States. 1
Aneurysmal disease can affect any segment of the aorta, from the aortic root to the aortic bifurcation. Juxtarenal Aortic Aneurysms (JAA) (where a specialty designed custom -made device (endograft)which has holes, or fenestrations ,on the graft body to maintain the patency of the visceral arteries) account for approximately 15% of abdominal aortic aneurysms.2
Successful aortic aneurysm treatment depends on either open replacement or endovascular exclusion of the aneurysmal segment with healthy artery proximal and distal to the repair.
The decision to treat an AAA is based on the associated risk of treatment, the risk of aneurysm rupture, the patient's life expectancy, and patient preference.
The primary determinant of rupture risk is maximum aneurysm diameter, with negligible rupture risk in aneurysms <4cm in diameter compared with aneurysms >8 cm . 3, 4.
The Society for Vascular Surgery recommends repair for all patients of acceptable perioperative risk with an AAA ≥5.5 cm in diameter as well as all patients with saccular and symptomatic aneurysms.5 ,6
These guidelines also suggest repair for women at a diameter of 5.0 cm.
Fenestrated Endovascular Aneurysm Repair (FEVAR) and Chimney Endovascular Aneurysm Repair (CHEVAR)are both effective methods to treat JAAs

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The primary outcome measure will be clinical success .
Time Frame: One year
|
Clinical success will be evaluated by Measurment of blood pressure by sphygmomanometer in mmhg Serum creatinine level in mg/dL
|
One year
|
One year patency of the endovascular graft
Time Frame: One year
|
One year patency will be assessed by CT angiography ( if it is patent or not). CT angiography can detect successful deployment of the endovascular device at the intended location or post endograft complications as type I or III endoleak , graft thrombosis, aneurysm expansion , aneurysm rupture. |
