A 51-year-old man with a ruptured pancreaticoduodenal artery (PDA) aneurysm caused by compression of the celiac artery by the median arcuate ligament and aortic dissection involving the celiac axis was transferred to our hospital for endovascular treatment. A 4-F catheter was advanced into the superior mesenteric artery through the narrow true lumen via the left brachial artery, and coil embolization of the aneurysm was successfully performed. In this case, rapid increase of blood flow in the superior mesenteric artery, which compensated for the decreased celiac blood flow by aortic dissection, increased hemodynamic stress on the PDA, leading to aneurysmal rupture.
一名51岁男性,因正中弓状韧带压迫腹腔干导致胰十二指肠动脉(PDA)动脉瘤破裂,且主动脉夹层累及腹腔干,被转至我院接受血管内治疗。通过左肱动脉经狭窄的真腔将一根4F导管推进至肠系膜上动脉,成功实施了动脉瘤的弹簧圈栓塞术。在该病例中,肠系膜上动脉血流迅速增加,弥补了主动脉夹层导致的腹腔干血流减少,但同时增加了PDA的血流动力学压力,导致动脉瘤破裂。
