â¢Extrarenal mycotic pseudoaneurysms are rare complications after kidney transplant.â¢Treatment of post-transplantation mycotic pseudoaneurysms often lead to loss of graft.â¢Early diagnosis and treatment can preserve grafts, lower limbs, and lives.â¢Success with the use of debridement, arterial reconstruction, and antifungal drugs is described.
BackgroundVascular complications after kidney transplantation may cause allograft loss. Here, we describe 2 patients with extrarenal mycotic pseudoaneurysm after kidney transplantation.PatientsPatient 1 was a 54-year-old man who developed pseudoaneurysm 60 days after transplantation, and patient 2 was a 48-year-old woman who was diagnosed with a pseudoaneurysm 5 months after transplantation.ResultsPatient 1 had a deceased-donor kidney transplant with end-to-side external iliac arterial anastomosis that was reconstructed 8 days after transplantation owing to rupture and major bleeding. At 60 days after transplantation, he had high serum creatinine level and Doppler ultrasonography showed a pseudoaneurysm of the arterial graft anastomosis and postanastomotic renal artery stenosis. Treatment included surgical excision of the pseudoaneurysm, vascular reconstruction, and fluconazole, with mycologic culture of the resected pseudoaneurysm showing Candida albicans. Patient 2 developed nondisabling intermittent claudication at 5 months after kidney transplantation, with a pseudoaneurysm subsequently observed on Doppler ultrasonography and computerized tomographic angiography. Treatment included renal artery thrombectomy and common iliac bypass to the hilar donor renal artery with inverted ipsilateral long saphenous vein. Operative samples showed C albicans, and she was treated with fluconazole. Both patients had satisfactory outcomes, and both kidney allografts were preserved.ConclusionsExtrarenal mycotic pseudoaneurysms after kidney transplantation require a high index of suspicion for early diagnosis, and preservation of the kidney graft may be achieved with the use of surgical treatment and antifungal therapy.
