Aorto-Left Renal Vein Fistula Caused by a Ruptured Abdominal Aortic Aneurysm

Abstract

Retroaortic left renal vein is a malformation in which the left renal vein courses dorsal to the abdominal aorta. In patients with abdominal aortic aneurysm, an aorto-left renal vein fistula can form if the left renal vein is sandwiched between the aneurysm wall and lumbar vertebrae. The patient was an 84-year-old man with lower back pain. We performed a contrast-enhanced computed tomography (CT), although renal dysfunction was noted. The CT showed a ruptured juxta-renal abdominal aortic with aorto-left renal vein fistula. This clinical condition can cause severe renal dysfunction, in spite of which an enhanced contrasted CT scan would be extremely informative preoperatively.

Variation of right renal artery duplication with retroaortic left renal vein: a case report

“…[16] It can be associated with abdominal aort aneurysm which may be ruptured into the retroaortic left renal vein forming an aorto-left vein fistula and causing numerous clinical findings. [4,17,18] It is reported that 94% of patients with this type fistulas had retroaortic left renal vein. [18] Arslan et al [19] investigated the etiological role of retroaortic left renal vein in the development of varicocele and found varicocele in 77% of patients with retroaortic left renal vein, which suggests its possible role.…”

Renal cysts and nephrolithiasis were the most frequently diagnosed conditions in patients with renal vascular variations, and these were considered to be due to negative effects of variations on renal function and hemodynamics.…”

Coexistence of the Aortic Aneurysm with the Main Vein Anomalies: Its Potential Clinical Implications and Vascular Complication

“…The fistula of the aorto-left renal vein in abdominal aortic aneurysms often co-occurs with the retroaortic left renal vein [51]. Mansour et al [52] reported that 94% of the patients with aorto-left renal vein fistula also had a retroaortic left renal vein.…”
