Inferior pancreaticoduodenal artery aneurysm associated with celiac artery occlusion diagnosed by multidetector computed tomographic angiography

Visseral arter anevrizmaları yaygın değildir ve tüm damar anevrizmalarının %0.1-0.2'sini oluşturur. Tüm visseral arter anevrizmalarının yalnızca %2'sini oluşturan pankreatikoduodenal arter anevrizmaları nadir görülürler. Pankreatikoduodenal arterlerin yalancı anevrizmaları pankreatit veya travmanın sonucu iken, ateroskleroz, fibromüsküler displazi ve konnektif doku hastalıkları gerçek anevrizmaların başlıca nedenleridir. Çöliyak arter oklüzyonu ile birliktelik gösteren inferior pankreatikoduodenal arter anevrizması nadir bir durumdur ancak rüptür riski ve bu durumda görülen yüksek mortalite oranı nedeniyle erken tanı ve acil tedavi gerektirir. Bu nadir durumun doğru tanısı çok kesitli bilgisayarlı tomografik anjiyografi ile kolaylıkla ve güvenilir bir şekilde konulabilir. Çok kesitli bilgisayarlı tomografik anjiyografi yüksek kaliteli üç boyutlu görüntüler sağlama olanağı verir ve anevrizmanın kesin lokalizasyonu ve boyutunun non-invaziv olarak belirlenmesine izin verir. Biz bu raporda çöliyak arter oklüzyonu ile birliktelik gösteren inferior pankreatikoduodenal arter anevrizmasının çok kesitli bilgisayarlı tomografik anjiyografi bulgularını sunuyoruz.

Çok kesitli bilgisayarlı tomografik anjiyografi ile tanı alan çöliyak arter oklüzyonu ile birliktelik gösteren inferior pankreatikoduodenal arter anevrizması

Aneurysms of the visceral arteries are uncommon and represent 0.1 to 0.2% of all vessel aneurysms. With only 2% of all visceral arterial aneurysms, aneurysms of the pancreaticoduodenal arteries are a rarity. False aneurysms of the pancreaticoduodenal arteries are the result of pancreatitis or trauma, whereas atherosclerosis, fibromuscular dysplasia and connective tissue disorders are the main causes of true aneurysms. Aneurysm of the inferior pancreaticoduodenal artery associated with occlusion of the celiac artery is a rare event, but the risk of rupture and the high mortality rate seen in this setting require early diagnosis and prompt management. An accurate diagnosis of this uncommon condition can be easily and reliably made by multidetector computed tomographic angiography. Multidetector computed tomographic angiography enables high quality three-dimensional reconstructed images and allows noninvasive determination of the exact location and the size of the aneurysm. In this report, we present multidetector computed tomographic angiography findings of the inferior pancreaticoduodenal artery aneurysm associated with celiac artery occlusion.
