OBJECTIVES: Renal neoplasm (RN) and abdominal aortic aneurysm (AAA) are occasionally discovered concurrently. The approach to synchronous malignancy and aortic aneurysm is controversial. METHODS: Between 1981 and 1999, concurrent RN and AAA were diagnosed in 50 patients at the Cleveland Clinic Foundation. Twenty-three patients were managed conservatively because of small asymptomatic AAA or metastatic disease; these patients were excluded from the study. The remaining 27 patients underwent operative management of both entities with a staged or simultaneous approach, and they form the basis of this article. RESULTS: AAA diameter ranged from 4.8 to 13 cm (mean, 6.0+/-1.8 cm). RNs were managed with radical nephrectomy in 11 patients (41%), partial nephrectomy in 10 patients (37%), or both in 6 patients with bilateral renal tumors (22%). The AAA repair was performed at the time of the urologic procedure in 11 patients (41%), before the urologic procedure in 13 patients (48%), or after the urologic procedure in 3 patients (11%). The AAA was addressed with open surgical repair in 24 patients (89%); recently, three patients (11%) underwent endovascular repair of the aneurysm and staged partial nephrectomy. The incidence of major perioperative complications was 23% (6 patients). Acute renal failure was the most common complication (3 [11%]) followed by acute respiratory failure (2 [7.4%]), pulmonary embolism (1 [3.7%]), and stroke (1 [3.7%]). At the mean follow-up of 57 months, there were no graft infections reported. The 5-year overall and cancer-specific survival rates were 62% and 81%, respectively. There was a significant difference in 5-year cancer-specific survival when comparing patients managed simultaneously versus staged (80% versus 35%, P =.007). CONCLUSIONS: The concurrent presentation of RN and AAA should not discourage one from treating both entities simultaneously because long-term survival is common. Endovascular repair of AAA holds promise as an attractive strategy in these complex patients.
