Pseudoaneurysms following allograft nephrectomy are rare and associated with significant morbidity and mortality. Ruptured iliac artery pseudoaneurysm in a septic patient is a challenge to treat due to limited options. This case report highlights a novel technique of using ipsilateral internal iliac artery to repair an infected pseudoaneurysm of the iliac artery related to explanted renal transplant.

| Case Study|| |
A 26-year-old young male presented to the emergency in shock, with a history of pain and expanding mass in the abdomen for 2 weeks. There was a significant increase in the bloody discharge from the left flank incision for the last 2 days. This patient is a case of chronic kidney disease on regular hemodialysis. He underwent graft nephrectomy (left) 1 month back for rejection. On examination, there was a large swelling occupying left half of the abdomen, extending into the pelvis and groin. The dressing was soaked with blood-mixed purulent discharge with a foul smell from the previous incision site. An urgent computed tomography angiogram revealed a large ruptured infected pseudoaneurysm of 20 cm × 15 cm arising from the left external iliac artery [Figure 1] and [Figure 2]. After resuscitation with fluids, blood products, and hemodialysis, he was planned for the surgery. For the procedure, our reconstruction options were limited, as the patient was in septic shock with hostile abdomen with a large ruptured infected aneurysm involving the pubic and groin. Reconstruction with a vein or synthetic graft,either anatomic or extra anatomic, carries a significant risk of secondary infection and bleeding. The risk continued to be same even with endovascular techniques. Among available vascular conduits, an arterial graft seems to be more resistant to infections, so we planned to use left internal artery as a conduit for the reconstruction. After vascular control, the infected pseudoaneurysm was excised with the evacuation of infected hematoma. After identifying rent in the external iliac artery, the artery was transected at the healthy area and closed. Then, the internal iliac was dissected, transected distally after ligation, and transposed to the distal part of the external iliac artery with end-to-end anastomosis [Figure 3]. His culture grew Acinetobacter species, sensitive to only carbapenems. The patient was kept on long-term antibiotics and he made a smooth recovery in postoperative period with normal vascularity to the leg [Figure 4]. Hence, we highlight the successful use of our novel technique of transposing internal iliac artery for the reconstruction of the external iliac artery in a septic hostile abdomen.

Pseudoaneurysms following allograft nephrectomy are uncommon, having been reported in 0.9%–14% of cases, but are associated with poor outcomes.,, The most important risk factor for the development of such complications is local infection or sepsis leading to anastomotic disruption with consequent pseudoaneurysm formation or rupture.,, Ruptured large infected pseudoaneurysms should be considered for an open surgical approach with the excision, debridement, and reconstruction with a graft. A two-staged approach has also been advocated with initial iliac artery ligation followed by extra-anatomical revascularization; however, the risk of amputation stands high if the ischemic insult is more.,,, Endovascular exclusion is currently the preferred option for the management of iliac artery pseudoaneurysm because it is a safe and with lower incidence of postoperative complications. However, durability and long-term outcomes have not been reported, more so in sepsis.
