Natural course of incidentally detected isolated Celiac Artery Dissection with hepatic artery occlusion.

Isolated celiac artery dissection (ICAD) is a rare entity with over 160 cases described in literature. We report a case of incidentally detected isolated celiac artery dissection during computed tomography evaluation for occult gastrointestinal bleeding. Though most cases of isolated celiac artery dissection are initially managed conservatively with antiplatelet and anticoagulants, some patients may require endovascular or occasionally surgical treatment. In our case, the celiac artery dissection had already progressed to cause hepatic artery occlusion and secondary collateral formation in the porta hepatis region. We retrospectively analyze the natural course of celiac artery dissection with hepatic artery occlusion in an asymptomatic patient for over 3 years.
