Purpose The authors wish to report their experience with the angiographic appearance and management (selective transcatheter embolization) of arterial lesions following partial nephrectomy. Materials and Methods Between February 2007 and January of 2011, 947 patients underwent a partial nephrectomy at our institution. Of these, 22 patients ages 28-83 (19 men, 3 women), were referred for selective angiography to treat hemorrhage or a suspected arterial lesion. Retrospective chart review was performed for the 22 patients. Angiographic technique and therapy for each patient was at the discretion of the individual operator. Follow-up consisted of clinical evaluation for the cessation of hematuria and cross-sectional imaging as part of the patient’s routine oncologic management. Results 20/22 patients presented with symptomatic postprocedure bleeding occurring within 10 +/- 4 days of partial nephrectomy. Two incidentally-noted and asymptomatic pseudoaneurysms were found in 2 patients on routine follow-up CT exams 120 +/- 2 days postprocedure. The most common bleeding complication for all patients was a solitary pseudoaneurysm formation, documented in 12 of the 22 patients (69%). The second most common complication was AV fistula in addition to pseudoaneurysm formation, documented in 6 of the 22 patients (27%). Solitary AV fistula was documented in only 2 of the 22 patients (9%). 19/22 patients were treated with coil embolization only. 4 of 22 patients were treated with a combination of coil and either alcohol, Gelfoam, PVA-particles or Ivalon-assisted embolization. All patients experienced short-term technical success except for one patient who presented with recurrent bleeding secondary to extravasation from an untreated vessel, which was observed to be partially thrombosed on initial angiographic evaluation. Conclusion Arterial injury secondary to partial nephrectomy presents with variable and recognizable angiographic appearances and often affects more than one segmental or interlobar artery. Angiographic coil embolization with or without particle assistance is an effective treatment strategy allowing for selective branch occlusion.
