“…1,2 They are commonly mycotic in origin. [3][4][5][6] Repair of these aneurysms poses a great challenge to restore the continuity of the recipient's native vessels. Use of synthetic vascular grafts may result in persistent infection; therefore, repair with autogenous grafts is preferable.…”

Repair of vascular defects in the presence of infection remains a challenging task in immunocompromised patients. We report two patients with postrenal transplant Aspergillus mycotic aneurysms of the allograft renal artery involving the external iliac artery which were excised along with the allograft. The defect in the external iliac artery was repaired successfully with interposition of autogenous internal iliac artery graft. Use of an internal iliac artery graft in such settings has been rarely reported in English literature. Autogenous internal iliac artery grafts provide a useful method to bridge the vascular defects created by radical debridement in the presence of fungal infections.

“…Although surgical repair or transplant nephrectomy was most commonly used, Fujikata et al reported a case of conservative treatment for mycotic aneurysm without rupture. 4,6,9,10 In recent years, endovascular or percutaneous treatment of extrarenal pseudoaneurysms has been widely used. Although endovascular embolization is the most suitable technique in the treatment of intrarenal pseudoaneurysms and fistulas, there are limited endovascular techniques for treatment of the extrarenal pseudoaneurysms of transplanted kidneys.…”

Extrarenal Pseudoaneurysm of the Arterial Anastomosis in a Renal Transplant: Endovascular Coil Embolization with Balloon Remodeling Technique

et al. 2011

Anastomotic pseudoaneurysms of transplanted kidneys are a very rare complication and encountered in less than 1% of such operations. They may be devastating and cause functional impairment and even loss of the graft. In this report, we present the first case of treatment of extrarenal pseudoaneurysm of arterial anastomosis in a renal transplant patient with endovascular coil embolization with the balloon remodeling technique. This method is mostly used in the treatment of wide-neck intracranial aneurysms.

“…Less common vascular complications include venous thromboses, anastomotic bleeding, arteriovenous fistulas, and PAs. As in liver transplants, PAs in renal allografts may form at the arterial anastomosis (5,11,12), occur after renal biopsy (13), or be due to infection (5,14,15).…”

“…Sonography has likewise proved useful in the diagnosis of splenic (25), hepatic (26)(27)(28)(29)(30), superior mesenteric (31,32), and celiac (33) artery aneurysms and PAs. In renal allografts PAs have traditionally been diagnosed with angiography, but they may also be detected with sonography (12,13) and CT (34). Recent reports have stressed the value of duplex sonography in the diagnosis of aneurysms, since it can demonstrate flow within the aneurysm (25,27,35).…”

Pseudoaneurysms Complicating Organ Transplantation: Roles of CT, Duplex Sonography, and Angiography

In a retrospective study of proved pseudoaneurysms (PAs) in 15 patients with transplanted organs (11 liver, three kidney, one pancreas), the results of computed tomography (CT), duplex sonography, and angiography were reviewed. Of the 15 cases of PA, eight occurred at the arterial anastomosis and seven were nonanastomotic. Three of the eight anastomotic PAs were caused by infection. Of the seven nonanastomotic PAs, four were caused by percutaneous biopsy, two were caused by infection, and one was of undetermined cause. In nine (60%) of the 15 patients the PAs were incidentally detected at imaging studies performed for other reasons. Diagnosis requires a high degree of suspicion. CT was performed in nine cases and duplex sonography in ten. The diagnosis of PA was made with CT in six (67%) patients and with duplex sonography in five (50%). CT and duplex sonography could not enable diagnosis when the PA was small, when the arterial anastomosis was not included in the field of study, or when enhancement with intravenously administered contrast material was suboptimal. Angiography depicted the PAs in all 15 patients. In three liver transplant recipients with gastrointestinal tract bleeding, the causative PAs were detected only with angiography.
