Anomalies of Inferior Vena Cava and Left Renal Vein: Risks in Aortic Surgery

Double inferior vena cava with interiliac vein: A case report and literature review

“…Most duplicated IVC cases are clinically silent and diagnosed incidentally by imaging performed for other reasons. However, these venous anomalies may have significant clinical implications, especially during retroperitoneal surgery and venous interventional radiology 4) . There were several case reports of deep venous thrombosis occurring in patients with duplicated IVC 5) .…”

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

“…Therefore, preoperative contrast-enhanced CT was useful in our case as well as previous reports mentioned. 1,4,5) It has been reported that approximately 3% of the population has retroaortic left renal vein. 6) In these people, the left renal vein does not become a landmark for renal artery during surgery because the vein is located dorsal to the aorta.…”

“…1) A caution is required to control bleeding from this type of fistula when an incision is made in the aortic aneurysm. 4,5) There are many reports in which an occlusion catheter was used in aorto-caval fistula cases to control indicated. When laparotomy was performed by abdominal midline incision, slightly bloody ascites was noted and hematomas of approximately 150 cc were observed proximal to the aneurysm and in the left retroperitoneal space.…”

The Importance of Venous and Renal Anomalies for Surgical Repair of Abdominal Aortic Aneurysms

“…Clamping the aorta is feasible above or below a retroaortic LRV type I. (Shindo et al, 2000). During the control of the patient's lumbar arteries from within the open sac of the aneurysm, there is a risk of damage especially in the case of retroaortic LRV type II.…”
