Complication arising from a duplicated inferior vena cava following laparoscopic living donor nephrectomy: a case report

Duplicated Inferior Vena Cava in a Patient With Ampullary Adenocarcinoma: A Case Report and Literature Review of Anatomical Variations

Duplicated inferior vena cava (IVC) is a rare anatomical anomaly as a result of failed regression of the left supracardinal vein during the embryonic stage. This anatomical variation has certain surgical implications and could lead to potential catastrophe perioperatively. We hereby report a case of a 54 years old male in whom a whipple procedure was performed with type 1 duplicated IVC for ampullary adenocarcinoma. Review of current literature of such anatomical anomaly will also be discussed. This venous anomaly must be kept in mind in all surgical procedures involving the retroperitoneum to minimise the risk of incomplete lymph node dissection and life-threatening bleeding, and to guide management for deep vein thrombosis in the post-operative setting.

Wilms tumor with inferior vena cava duplication: a rare case report

Background

Wilms tumor is the most common renal tumor of childhood. Duplication of the inferior vena cava is an uncommon anomaly. In the present study, we present a case of Wilms tumor with the inferior vena cava duplication, which has not been reported previously.

Case presentation

A 14-month-old female presented with an enlarging abdominal mass. Computed tomography imaging demonstrated a large mass in the right kidney, duplication of the inferior vena cava below the renal veins and compression of the right inferior vena cava caused by the enormous mass. A right radical nephrectomy was performed. Final pathology was consistent with Wilms tumor. Postoperative adjuvant chemotherapy was executed. Computed tomography imaging at 3 months postoperatively showed the right inferior vena cava played a dominant role and the left inferior vena cava was not detected clearly. During the follow-up of 18 months, no local recurrence or metastasis has been observed.

Conclusion

It is important to recognize the case of Wilms tumor with the inferior vena cava duplication to avoid injury of retroperitoneal venous anomalies and life-threatening hemorrhage during surgery through preoperative computed tomography.

Pure retroperitoneoscopic donor nephrectomy in duplication of inferior vena cava: A series of four cases

Aim:

Complex vascular anatomy poses a major challenge to the donor surgeon. Here, we have described the technical nuances in retroperitoneoscopic living donor nephrectomy for the left kidney in the situations of a rare vascular anomaly of duplication of inferior vena.

Materials and Methods:

Between September 2005 and June 2016, 1460 retroperitoneoscopic living donor nephrectomy were carried out in single surgical unit of our institution. Out of these four donors were found to have duplication of inferior vena cava (IVC). We retrospectively analyzed the prospectively collected data of these donors and studied the operative details for managing the duplicated limb of the IVC.

Results:

The mean age of the donors was 42.5 (range 30–54) years. Mean body mass index was 26.9 (range 25.2–28.6) kg/m². Mean operative time (defined as between giving skin incision to the skin closure [O. T]), was 230 (range 185–310 min). Mean Warm ischemia time (defined from clamping of the renal artery to the starting of the cold HTK perfusion, [WIT]) was 136 s (range 105–178 s). In two cases, the renal vein could be controlled distal to the duplicated limb. In one case, the duplicated limb was clipped while in another a stapler was used to take a cuff of IVC.

Conclusion:

Retroperitoneoscopic donor nephrectomy can be performed safely in cases of duplication of IVC. Preoperative computerized tomography angiography with vascular reconstruction and surgical expertise is desirable in carrying out the procedure.
