Abstract

A true aneurysm is defined as an enlargement of an artery resulting in a diameter more than 1.5 times the anatomic
1 size .It can be fusiform when it covers the entire perimeter of the vessel,or saccular when it bulges on one side of
the artery.The pseudoaneurysm is a pulsating encapsulated haematoma in communication with the lumen of the
ruptured vessel,which affects the the intima and the media and which is stopped from developing by the adventitia
2 and the surrounding connective tissue. Geographically, aneurysm can be broadly divided into intracranial and
extracranial types.While the neurosurgeon manages the intracranial types, the vascular surgeon manages the
3 extracranial types .Vascular surgeons also do divide the extracranial types into central(abdominal-aorto-iliac,
thoracic including ascending, transverse aortic arch and descending), peripheral(extremities) and
4` visceral(splanchnic arteries) . Splanchnic artery aneurysm includes the coeliac, superior mesenteric, inferior
mesenteric arteries including their branches. Of all intra-abdominal aneurysms, only around 5% are due to the
5 6 splanchnic arteries,which could be either true or pseudo . The prevalence has been estimated at 0.1-0.2% .
