Abstract

Currently, partial nephrectomy for patients with malignant renal tumors has become the procedure of choice for elective indications. Attempts have been made to use minimally invasive endoscopic procedures to replace the standard open partial nephrectomy. Laparoscopic partial nephrectomy can be technically challenging and be associated with vascular complications such as pseudoaneurysm. We report here on a case of renal artery pseudoaneurysm that occurred after laproscopic partial nephrectomy for renal cell carcinoma treated by percutaneous selective angioembolization.

CT scan reveals a 2.6x2.5 cm heterogeneously enhancing solid mass at the left lower renal pole.

Fig. 2.

(A) Follow-up contrast CT scan of the kidney shows a large collection of contrast in the left lower renal pole, which was compatible with a pseudoaneurysm. (B) the 3-D volume rendered CT scan with intravenous contrast demonstrates a 3.5 cm sized saccular pseudoaneurysm (white arrow) arising from the lower segmental branch of the left renal artery.

Fig. 3.

Digital subtraction angiogram of the left renal artery shows a saccular pseudoaneurysm, about 3 cm in diameter, in the lower field of the remaining renal parenchyma.

Fig. 4.

The follow-up 3-D volume rendered CT scan at 1 month after the embolization shows total occlusion of the pseudoaneurysm with histoacryl/lipiodol mixtures (white arrow).
