Transplant renal artery False Aneurysm
Clinical kidney journal, 2012Co-Authors: Ana Rocha, S. Pedroso, Diogo SilveiraAbstract:The transplant renal artery False Aneurysm is a rare event but can be fatal. We report the case of a patient with a False Aneurysm, which appeared 6 years after transplantation. The clinical presentation was an increase of the creatinine value and de novo graft hydronephrosis. The first ultrasound performed showed no Aneurysm, leaving doubt whether this would not have been caused iatrogenically with the nephrostomy catheter placement. On the other hand, the resolution of hydronephrosis with Aneurysmectomy leads us to believe that the Aneurysm had existed previously. We consider this an interesting case by the manner of presentation and the success of the approach. A 44-year-old male patient received a first kidney transplant from a cadaveric donor in August 2005. Active bleeding was detected in the early post-operative period. He was reoperated and an arterial anastomotic dehiscence needing a vascular reconstruction was found. The remaining post-transplant period was unremarkable with a baseline serum creatinine of 2.0 mg/dL. In October 2011, he had an asymptomatic increase in serum creatinine to 2.7 mg/dL and urine analysis was completely normal. Ultrasonography showed a de novo hydronephrosis. Provisional diagnosis of obstruction was contemplated and a percutaneous nephrostomy was placed. Renal function did not improve. Ultrasonography was repeated showing a hypoechoic mass with a pulsatile flow pattern by colour Doppler scanning and maintained hydronephrosis. Subsequent computed tomography angiography confirmed a 4 × 4 cm False Aneurysm at the anastomosis of the transplanted renal artery with the right external iliac extern (Figure 1). Digitally subtracted angiography was done prior to surgery (Figure 2). The resection of the False Aneurysm was performed and the transplanted renal artery was anastomosed to the external iliac artery. Post-operatively, creatinine improved to basal value and ultrasonography showed no hydronephrosis. Fig. 1.

Digitally subtracted angiography showing the False Aneurysm at the junction of the transplanted renal artery with the right external iliac artery. False Aneurysms following kidney transplantation are rare, but can be potentially devasting and cause functional impairment and even loss of the graft due to the risk of rupture [1]. Patients are usually asymptomatic and they are diagnosed incidentally. They can be managed conservatively with regular monitoring if the False Aneurysms are small. When they cause clinical signs or risk rupture, interventional treatment is required.

False Aneurysm of the popliteal artery a rare complication of total knee replacement
Knee Surgery Sports Traumatology Arthroscopy, 2000Co-Authors: C D Karkos, G J L Thomson, S P Dsouza, V PrasadAbstract:We describe a 72-year-old woman with a False Aneurysm of the mid-popliteal artery after a total knee replacement, presenting with a pulsatile swelling and an audible bruit in the popliteal fossa. The diagnosis was confirmed by duplex ultrasound. Surgical repair was undertaken using a saphenous vein patch to reconstruct the arterial defect. A False Aneurysm of the popliteal artery following total knee replacement is an extremely rare occurrence. To our knowledge, only four other cases have been reported in the English-language literature.

False Aneurysm of the superior lateral geniculate artery following total knee replacement
Knee, 2002Co-Authors: Matthew Moran, John Hodgkinson, William F TaitAbstract:Arterial complications following Total Knee Replacement are uncommon. We present a case of False Aneurysm of the superior lateral geniculate artery presenting in the immediate postoperative period with continued bleeding from the surgical wound. This is the first case of False Aneurysm of this vessel described following Total Knee Replacement. A method of treatment is outlined. Early consultation with vascular surgery colleagues is recommended to prevent delayed diagnosis of serious vascular complications.

False Aneurysm 14 years after total hip arthroplasty
Journal of Arthroplasty, 2000Co-Authors: Christian Bach, Iris Steingruber, Cornelius Wimmer, Michael Ogon, Bernhard FrischhutAbstract:Many reports of complications after total hip arthroplasty have been published concerning typical orthopaedic problems. Relatively little attention has been paid to serious vascular injuries, such as the development of a False Aneurysm. To our knowledge, 10 cases have been described in the English literature. The mean time interval between surgery and initial manifestation of the Aneurysm was 9 months in these cases. Our patient developed first symptoms of a False Aneurysm 14 years after surgery. A minimally invasive technique was used to cut the Aneurysm from perfusion. Removal of the total hip arthroplasty was performed through a retroperitoneal and lateral approach.

False Aneurysm of the profunda femoris artery after total hip arthroplasty
Journal of Arthroplasty, 2000Co-Authors: Masahiko Nozawa, Masahiro Irimoto, Katsuo Shitoto, Tomohiko Hirose, Katsuhiko Maezawa, Hisashi KurosawaAbstract:Abstract A False Aneurysm of the profunda femoris artery occurred after metal-on-metal total hip arthroplasty in 70-year-old woman. At 39 days after the operation, the wound suddenly opened, and a large hematoma was discharged. Eleven tornade coils were inserted into the base of the False Aneurysm, and the bleeding was arrested. The prevention and management of this complication are discussed.
