Double left renal vein associated with abdominal aortic aneurysm
1Second Department of Surgery, Faculty of Medicine, Kagoshima University, 8-35-1 Sakuragaoka, Kagoshima 890-8520, Japan.
Summary
A rare double left renal vein anomaly complicated abdominal aortic aneurysm surgery, causing hemorrhage. Prompt repair and aortic replacement led to an uneventful recovery, highlighting the need for preoperative imaging.
Area of Science:
- Vascular Surgery
- Anatomical Variations
- Medical Imaging
Background:
- Abdominal aortic aneurysm (AAA) repair is a common vascular procedure.
- Anatomical variations, such as double left renal vein, can complicate AAA surgery.
- Preoperative imaging is crucial for surgical planning.
Observation:
- A 72-year-old male with AAA presented with a rare double left renal vein.
- During surgery, massive hemorrhage occurred due to injury of a retroaortic left renal vein.
- The double left renal vein formed a ring around the abdominal aorta.
Findings:
- The patient underwent successful abdominal aortic replacement and prompt repair of the injured renal vein.
- The patient experienced an uneventful postoperative course with no renal complications.
- The double left renal vein anomaly was identified preoperatively on computed tomographic (CT) scan but was initially missed.
Implications:
- Preoperative contrast-enhanced CT scans are essential for identifying venous anomalies in AAA patients.
- Awareness of venous anomalies is critical for preventing intraoperative complications during AAA surgery.
- Routine inclusion of venous anomaly assessment in preoperative AAA imaging protocols is recommended.
