Aim:Radiocephalic arteriovenous fistula (AVF) at wrist is the vascular access of choice for dialysis. In the absence of a suitable vein at the wrist, a brachiocephalic fistula at elbow is usually constructed. In order to avoid the complication of vascular steal syndrome associated with the brachiocephalic fistula, an alternative operative technique involving the creation of radio-median cubital vein / radiocephalic fistula at elbow was evaluated.Settings and Design:Retrospective study.Materials and Methods:Between January 1990 and October 2005, 320 patients underwent creation of radio-median cubital vein / radiocephalic AVF at elbow as a primary procedure or following failure of a fistula at the wrist. A transverse skin incision was made 4cm below the elbow crease, centering in line with the brachial artery pulsation. The median cubital vein / cephalic vein was anastomosed to the radial artery in end to side fashion. The surgical complications and patency of the fistulae were analyzed in the immediate and late postoperative period.Results:Mean operative time was 55 ± 7.15 min. There were no major intraoperative complications. Immediate patency and a palpable distal radial pulse were present in all the patients. Mean time to fistula maturation was 26 ± 5.2 days. No patient developed a vascular steal syndrome at a median follow-up of 54 months (range 12–168 months) Early fistula failure was seen in 16 (5%) patients whereas eight (2.5%) fistulas failed at a later date. Pseudoaneurysm of the arterialized vein at the fistula site developed in only one (0.3%) patient. Pseudoaneurysm proximal to the anastomosis developed in three (0.9%) patients. Sixteen (5%) patients requested for closure of the fistula following successful renal transplant due to unsightly dilated veins and continuous noisy murmur disturbing their sleep.Conclusions:The radio-median cubital vein / radiocephalic AV fistula at elbow is safe and is a better vascular access procedure for hemodialysis than brachiocephalic fistula because it leads to the dilatation of both the cephalic and the basilic veins with no incidence of vascular steal phenomenon in our experience. Patency and flow rates are similar to brachiocephalic fistula.
BackgroundTraumatic amputation of the penis is a rare surgical emergency. Although repair techniques have been well described in literature, failure of replantation and its causes are poorly understood and reported. Herein, we report the case of a 9 year old boy who underwent replantation of his amputated penis with delayed failure of the surgery, along with a discussion of recent advances in the management of this condition.Case PresentationA 9-year-old boy was referred to our hospital for traumatic amputation of the penis. Papaverine aided microsurgical replantation of the severed part was performed, but by 48 h, the glans became discoloured and necrosis set in by 4 days. Unfortunately, by day 12 two thirds of the re-implanted penis was lost along with overlying skin.ConclusionReplantation of an amputated penis in a pediatric patient is a daunting task even for experienced surgeons. The vasodilatory effect of papaverine for vascular anastomosis is well described, but the use of a paediatric cannula for identification and instillation of papaverine into penile vasculature, has not been described for the repair of penile amputation. Despite its apparent failure, we believe this technique may be valuable to surgeons who might encounter this rare event in their surgical practice, especially in resource limited settings like ours.
The supernumerary kidney especially on right side is a rare diagnosis. Only few case reports are documented in literature. We report a case of Right supernumerary kidney with partial fusion of right accessory kidney to upper kidney.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
