Emergent Embolization of a Very Late Detected Pseudoaneurysm at a Lower Pole Subsegmental Artery of the Kidney after Clampless Laparoscopic Partial Nephrectomy

We reported a case of a renal artery pseudoaneurysm occurred about four months after a clampless laparoscopic PN. A 49-year-old female underwent a clampless laparoscopic PN for a right renal tumor with high surgical complexity. The patient experienced an intraoperative blood loss from renal bed and the surgeons performed a deep medullary absorbable suture. Three months after surgery the patient underwent a renal ultrasonography with good results. The patient came to our emergency department 115 days after surgery with a hypovolemic shock stage 3. Her CT scan showed a pseudoaneurysm of a lower pole vessel of the right kidney. She underwent a superselective embolization of the segmental renal artery. The surgical complexity of the tumor, the anatomical relationships with the renal sinus and the deep medullary suture could be responsible for the development of the pseudoaneurysm. The authors presented an unusual case of a very late detected pseudoaneurysm of a renal vessel, suggesting that all very complex renal tumors removed with a minimally invasive technique should be followed up closely at least during the first six-months in order to early detect this major complication.Curr Urol 2016;10:105-107
