Coexistence of Multiple Simple Hepatic and Renal Cysts and Aortic Dissection

Abstract

We experienced a rare case of retrograde type-A acute aortic dissection with patent false lumen complicated with multiple simple hepatic and renal cysts. The patients suffered stroke at the onset of aortic dissection and cardiopulmonary bypass was contraindication. Thoracic endovascular aortic repair was performed to exclude the primary entry in the distal aortic arch. For 2 years from January in 2022 to December in 2023, 45 patients underwent surgery (including endovascular repair) for type-A acute aortic dissection in our hospital. Among them, there were 14 cases (31.1%) with simple renal cyst, 11 cases (24.4%) with simple hepatic cyst, 20 cases (44.4%) with either cyst, 5 cases (11.1%) with both cysts, and one case (2.2%) with both multiple simple hepatic and renal cysts. Although matrix metalloproteinases have been suggested to play a role in common etiology of simple hepatic and renal cysts and aortic dissection, further investigations would be required.
