Superior mesenteric artery aneurysm

The superior mesenteric artery aneurysm is the third most common VAA but only accounts for 6% of all splanchnic aneurysms. It is typically associated with an infectious etiology such as endocarditis. Thrombosis and dissection can be seen with these lesions and patients can present with symptoms of mesen-... 

Catheterisation of coeliac and superior mesenteric arteries is usually performed from the femoral artery. The radial or brachial approach may be preferred especially where the patient is thin and the angle with the aorta very acute. A 4- or 5-F visceral curved Glidecatheter (Terumo) and hydrophilic wire will allow more distal catheterisation which may be required to diagnose and cross the aneurysm or... 

Australian, British and American surgeons have looked at the intermediate results of the US trial for the fenestrated graft to evaluate the safety and shortterm effectiveness of the device.Thirty patients with short proximal necks were enrolled in the trial and treated with the Cook Zenith custom-fenestrated devices. None of the visceral arteries, renal or superior mesenteric, were lost as a result of the surgery. After 24 months there were no aneurysm-related deaths, ruptures, or conversions to open surgeries. There were 6 incidences of type II endoleak at 12 months and 4 at 24 months. In all patients the diameter...
