AI Article Synopsis
- * The patient also had Leriche syndrome, which causes blockage in the aorta and affects blood flow to the legs, and the CT angiography revealed collateral arteries that help with circulation.
- * A robot-assisted laparoscopic partial nephrectomy was performed to remove the tumor while carefully marking and avoiding the collateral arteries to maintain blood flow, and the final pathology confirmed clear cell renal cell carcinoma.
Article Abstract
A 71-year-old man was referred to our hospital for treatment of a 2 cm-sized right renal mass incidentally found by computed tomography (CT) and was diagnosed with right renal cell carcinoma cT1aN0M0. Contrast-enhanced CT revealed that the aorta was completely occluded below the inferior mesenteric artery origin, and Leriche syndrome was diagnosed. CT angiography showed several collateral arteries along the abdominal wall. A robot-assisted laparoscopic partial nephrectomy was performed to treat renal cell carcinoma. Preoperatively, we marked the collateral arteries using ultrasonography to avoid injury during trocar insertion. We did not observe any decrease in blood flow in the right leg during the operation. The pathological diagnosis was clear cell renal cell carcinoma. Leriche syndrome is a chronic occlusive disease involving the infrarenal aorta and the iliac arteries. Since lower limb blood flow is dependent on collateral circulation, it is important to avoid injuring the collateral arteries during surgery.
