Distal çölyak arterden origin alan splenik arter diseksiyonu ile kısmen tromboze proksimal splenik arter disekan anevrizması

Splenik arter diseksiyonu oldukça ender rastlanan ve yaşayan hastalarda tanısı zor konan bir antitedir. Splenik arter anevrizması (SAA) ise en sık saptanan abdominal viseral anerizma olup asemptomatik seyretmekte ve genellikle splenik arterin orta veya distal segmentinde saptanmaktadır. Splenik arter diseksiyonları, büyük çoğunlukla postmortem çalışmalarda tanı konmakta öncesinde açıklanamamış üst abdomen semptomları ile seyretmektedir. Bu yazıda, hastamızın çöliak arter distalinden splenik arter 1/3 proksimaline uzanan diseksiyon flebi ile kısmen tromboze olmuş disekan anevrizmayı gösteren çok kesitli bilgisayarlı tomografi (ÇKBT) görüntüleri ile birlikte bu antite tartışılmıştır.

A partially thrombosed dissecting aneurism of the splenic artery extending from the coeliac origin of the artery

Splenic artery dissection is an extremely rare entity rarely diagnosed in living individuals. However, splenic artery aneurysms (SAA) are the most frequent vascular aneurysms of the abdominal viscera and they are asymptomatic, usually located in the middle or distal segment of the splenic artery. Splenic artery dissections are almost always diagnosed at postmortem usually in patients with previous unexplained upper abdominal symptoms. We report multidetector computed tomography (MDCT) scans of a splenic artery aneurysm with a dissecting flap extending from the distal end of the coeliac artery to the proximal one third of the splenic artery with a partially thrombosed false lumen. When we searched the English language literature this is one of the few cases reported as having been diagnosed in a living patient.
