Renal Transplant Patient After Type A Aortic Dissection and Renal Malperfusion.

Acute type A aortic dissection (AAD) is a life-threatening emergency with high mortality. Preoperative organ malperfusion significantly worsens surgical outcomes. Isolated renal malperfusion is common in acute type A aortic dissection, increasing the risk of postoperative renal ischemia and early mortality. This case involves a young patient with renal malperfusion due to left renal artery closure by an intimal flap and true lumen compression of the abdominal aorta affecting both renal arteries. Endovascular intervention was not feasible. The patient later underwent a successful kidney transplant and has been followed up for years without complications.
