This is a case of a 78-year-old male patient with multiple angiomyolipomas of a solitary right kidney. The largest of these tumors (maximum diameter: 13.4 cm) caused significant extrinsic compression of the inferior vena cava complicated by thrombosis of this vessel. Treatment of thrombosis with anticoagulants had been ineffective and the patient had experienced a bleeding episode from the largest right renal angiomyolipoma, which had been treated by transarterial embolization in another institution, 4 months prior to our intervention. Our approach included superselective transarterial embolization of the dominant, right kidney angiomyolipoma with hydrogel microspheres, which was combined, 20 days later, with ultrasonographically guided radiofrequency ablation. Both interventions were uneventful. Computed tomography 2 months after ablation showed a 53% reduction in tumor volume, reduced space-occupying effect on inferior vena cava, and resolution of caval thrombus. Nine months after intervention the patient has had no recurrence of thrombosis or hemorrhage and no tumor regrowth has been observed. The combination of superselective transarterial embolization and radiofrequency ablation seems to be a feasible, safe, and efficient treatment of large renal angiomyolipomas.

Effective Treatment Modality

AbstractRenal artery pseudoaneurysm (RAP) is a serious complication that can lead to severe hematuria, blood loss, and life-threatening hemorrhagic shock. A pseudoaneurysm is defined as an arterial wall deficiency that results in the accumulation of oxygenated blood in the nearby extraluminal region. Partial nephrectomy, a parenchymal sparing method, carries a lower risk of postoperative development of chronic kidney disease than total nephrectomy but a higher risk of iatrogenic vascular lesions such as RAP or arteriovenous fistulas. Pseudoaneursyms may develop secondary to arterial transection during tumor resection or due to arterial puncture during suture ligation of the resection bed. Emergency transarterial embolization is an effective treatment modality for patients with hemodynamic instability that does not lead to significant worsening of renal function. The recent literature reports an incidence of 2.7 to 21.7% of RAP or arteriovenous fistulas after partial nephrectomy. We report a case of severe bleeding with massive hematuria due to RAP, which was detected with duplex sonography.
