AbstractRenal retransplantation after a failed prior kidney and pancreas transplant is being increasingly performed. In these complex cases, both iliac fossae have been used for prior transplants, and the placement of the new allograft can be problematic. We describe our experience with an alternative technique for renal retransplantation (RRTx) in the setting of severe bilateral aortoiliac atherosclerosis or scarring and fibrosis on the iliac vessels. Nephrectomy of the failed allograft is performed, and the renal vessels of the failed allograft (RVFA) are preserved. The new kidney is implanted on RVFA at the same operative time. This technique was attempted and successfully accomplished in a total of six patients (mean operative time = 240 ± 63 min). One postoperative complication occurred: poor arterial inflow to the allograft, being corrected reoperatively. Hospitalizations ranged from five to eight d. Five of the six patients were alive with a functioning allograft at last follow‐up (a single graft failure occurred 21 months postoperatively in the setting of post‐transplant lymphoproliferative disease that also led to patient death). Renal vessels of the failed allograft seem to be suitable alternative vascular conduits for renal retransplantation after prior kidney and pancreas transplants.

Background and Aims . EUS-FNA is an accurate and safe technique to biopsy mediastinal lymph nodes. However, there are few data pertaining to the role of EUS-FNA to biopsy central lung masses. The aim of the study was to assess the diagnostic yield and safety of EUS-FNA of indeterminate central mediastinal lung masses. Methods . Design: Retrospective review of a prospectively maintained database; noncomparative. Setting: Tertiary referral center. From 10/2004 to 12/2010, all patients with a lung mass located within proximity to the esophagus were referred for EUS-FNA. Main Outcome Measurement: EUS-FNA diagnostic accuracy and safety. Results . 73 consecutive patients were included. EUS allowed detection in 62 (85%) patients with lack of visualization prohibiting FNA in 11 patients. Among sampled lesions, one patient (1/62 = 1.6%) had a benign lung mass (hamartoma), while the remaining 61 patients (61/62 = 98.4%) had a malignant mass (primary lung cancer: 55/61 = 90%; lung metastasis: 6/61 = 10%). The sensitivity, specificity, and accuracy of EUS-FNA were 96.7%, 100%, and 96.7%, respectively. The sensitivity was 80.8% when considering nonvisualized masses. One patient developed a pneumothorax (1/62 = 1.6%). Conclusions . EUS-FNA appears to be an accurate and safe technique for tissue diagnosis of central mediastinal lung masses.
