Splanchnic Artery Aneurysms

The Endovascular Treatment of a Ruptured Aneurysm of the Middle Colic Artery Combined With an Isolated Dissection of Superior Mesenteric Artery

“…Isolated SMAD has been shown to be associated with cystic medial degeneration, atherosclerosis, and fibromuscular disease. 2 Coexistence of SAM and cystic degeneration was reported in a patient with aneurysms of the abdominal aorta and the iliac artery. 4 However, in this case, the etiologic association of middle colic artery aneurysm with SMAD is not definite.…”

Pancreaticoduodenal Artery Aneurysm Formation with Superior Mesenteric Artery Stenosis

“…1) PDAAs are classified as either true or false aneurysms. While false PDAA results from surrounding inflammation such as pancreatitis or trauma, true PDAA is degenerative or related to atherosclerosis and remains elusive in origin.…”

“…While false PDAA results from surrounding inflammation such as pancreatitis or trauma, true PDAA is degenerative or related to atherosclerosis and remains elusive in origin. 1) Sutton, et al reported that true PDAA is associated with celiac stenosis or occlusion, and that 80% of patients with true PDAA had celiac stenosis. 2) Celiac stenosis or occlusion, which is a result of atherosclerosis, fibromuscular hyperplasia or compression by the median arcuate ligament may induce hemodynamic changes in the pancreatic arcade.…”

Aneurisma sacular de arteria esplenica: tratamento endovascular ou cirurgico convencional?

“…Although uncommon, with an incidence that accounts for around 5% of intra-abdominal aneurysms, the risk of mortality is great if this kind of aneurysm ruptures. This is why it is important to raise awareness of this vascular disease 3,4 .…”

“…The most common site of splanchnic aneurysms is at the splenic artery 4 (60% of cases), with a prevalence in the general population of 0.1 to 2% 3 . Pregnancy is one of the clinical conditions that favors the appearance these aneurysms 4 .…”
