RESUMO
BACKGROUND: In a kidney transplant tertiary referral center; we compared 3 operating team configurations of different surgical specialties to highlight the effect of the operating surgeon's specialty on various operative details and procedural outcome. METHODS: A total of 50 cases of living donor transplantations were divided into 3 main groups according to the operating surgeons' specialty, the first group (A) includes 12 patients exclusively operated on by urologists with advanced training in transplantation, the second group (B) includes 35 patients operated by combined surgical specialties; a urologist and a vascular surgeon both with advanced transplantation training, and a third group (C) includes 3 cases where the transplant operation commenced with operating urologists as in group (A) but required intraoperative urgent notification of a vascular surgeon to manage unexpected intraoperative technical difficulties or major complications. Cases were studied according to operative details, anastomosis techniques, ischemia times, total procedure time, recovery of urinary output, intensive care unit (ICU) stay, postoperative surgical complications and serum creatinine level for up to 3 years of follow-up. RESULTS: Study of operative details revealed that total duration of graft ischemia was significantly shorter in group (B) and significantly longer in group (C) (P value 0.001), Total procedural duration also varied significantly between the 3 groups, group (B) being the shortest while group (C) was the longest (P value less than 0.001). Technically; group (A) used only end to end arterial anastomosis as a standard technique, while group (B) used both end-to-end and end-to-side anastomoses as required per each case. End to side anastomosis in group (B) yielded better immediate graft response in the form of change in color, texture, earlier and more profuse postoperative urine volumes (P value 0.025). Furthermore, anastomosis to common and external iliac arteries (group B) yielded earlier and higher urine volumes than the internal iliac artery (P values 0.024 and 0.031 respectively). Group (B) recorded significantly less postoperative perigraft hematomas and lymphoceles compared to the other 2 groups. Equal rates of urine leaks, ICU stay, creatinine levels, patient and grafts survival rates among groups (A) and (B), while postoperative recovery and ICU stay duration were more lengthy in the complicated group (C). CONCLUSIONS: A vascular surgeon operating in a transplantation team would deal comfortably and efficiently with various vascular related challenges and complications, thus avoiding unnecessary time waste, complications and costs.

Blunt trauma of the brachial artery (BA) in pediatric age is often associated with neurological and orthopaedic injuries. Acute ischemic hands warrant immediate exploration, but the management of warm-pulseless hands following elbow trauma is controversial. This study evaluates the role of conservative treatment of blunt BA injuries in children with non-threatened hands. Eleven children with blunt trauma onto the BA having warm-pulseless hands were studied retrospectively. After a mean follow-up period of 2.5 ± 0.9 years, all cases had thorough clinical examination and duplex scan to assess the treatment outcomes. At the end of follow-up period, all subjects had well-perfused hands with intact wrist pulses. The duplex scan revealed those who had interposition grafts to be patent and one case had an aneurysmal dilatation. There was no statistical significance difference between affected and healthy forearms regarding the mean peak systolic velocity at the wrist, affected side was 62 ± 0.82 cm/s versus 68 ± 0.57 cm/s for opposite side ( p -value = 0.14). Patients with blunt BA trauma and warm-pulseless hands could be managed safely with conservative treatment, leaving surgical exploration for those who did not regain pulses after 48 hours. Duplex ultrasound can safely verify the patency of surgical repair and can be used for surveillance to detect future complications.
