  Postanastomotic narrowing resulting from subintimal hyperplasia is a well-known phenomenon. In the current study the authors compared a metallic circle and conventional suture technique inPostanastomotic narrowing resulting from subintimal hyperplasia is a well-known phenomenon. In the current study the authors compared a metallic circle and conventional suture technique in anastomoses performed in two ends of external jugular vein grafts interposed in carotid arteries of rabbits. They recorded the patency rates, fluid flow rates, and histological effects of the circle on the anastomotic line and compared them with conventional suture anastomoses. In 16 rabbits (experimental group) a standard suture was used in both ends of the jugular vein graft transposed to the carotid arteries on one side. On the other side, circle anastomoses were performed on both ends of the vein graft. In an additional 8 rabbits (control group), the anterior jugular veins and carotid arteries were dissected on both sides and left. During postoperative week 12, in 8 rabbits of the experimental group, the flow rates of carotid arteries were measured in vitro, and intraluminal silicone casts were prepared. In the remaining 8 experimental rabbits, carotid angiographies were performed and anastomotic segments were harvested for histological examination. Flow rates were also measured in the control group, and artery and vein segments were harvested. The patency rates of the vein grafts with metallic circle anastomoses were 100%, whereas conventional suture patency was 75% at week 12. Flow rates were significantly higher in the metallic circle-anastomosed vein grafts (74 ml per minute vs. 123 ml per minute, mean values; p < 0.05). Histological examination revealed reduced intimal thickness in the metallic circle anastomoses compared with conventional suture anastomoses. Dilatation of the arteriovenous end-to-end anastomotic line by a rigid circle prevents anastomotic narrowing in the long term.

  The authors present two unsuccessful clinical cases of end-to-side neurorrhaphy. In the first patient the distal median nerve was coapted in an end-to-side manner to the intact ulnar nerve. In theThe authors present two unsuccessful clinical cases of end-to-side neurorrhaphy. In the first patient the distal median nerve was coapted in an end-to-side manner to the intact ulnar nerve. In the other patient four cables of sural nerve graft were used to bridge the ulnar nerve and the intact median nerve by two end-to-side coaptations. Neurorrhaphies were performed via epineural sutures through epineural windows. Both of the cases failed to demonstrate any signs of regeneration either clinically or as evidenced by electromyography, Semmes-Weinstein monofilament test, or 256-Hz vibration tests at 18 and 21 months' follow-up respectively.

  Bone fixation in digital replantation must provide adequate rigidity, and must be applied in a fast and easy manner. Various fixation methods have been used so far with certain advantages andBone fixation in digital replantation must provide adequate rigidity, and must be applied in a fast and easy manner. Various fixation methods have been used so far with certain advantages and disadvantages. The authors report two new intramedullary proximal phalangeal implant designs to secure two amputated bone segments tightly. They compare their intramedullary implants with commonly applied K-wire fixation methods and plate fixation via biomechanical analysis in terms of bending rigidity and distraction strength. Their two-sided asymmetrical screw provided the highest rigidity and distraction strength, whereas the hook-trap system was nearly equal to cross-K-wire fixation. Intramedullary bone fixation may be a feasible method of bone fixation, and resorbable implant materials and different implant configurations deserve further investigation.

We report on a new microvascular end-to-side anastomosis technique using a silver ring around the anastomotic circumference. The purpose of this study was to compare the effectiveness of this technique with conventional end-to-side vessel anastomosis.Forty Sprague-Dawley rats were divided into two groups. Twenty rats were used to assess the external ring method in end-to-side anastomosis between carotid arteries and anterior jugular veins and the remaining 20 formed the control group with conventional end-to-end anastomosis.The anastomosis time was 26.4 min for standard suture anastomosis and 18.4 min for the external ring technique (P< 0.01). Patency was 95% with standard technique and 100% using the external ring (P> 0.05). The external ring technique of end-to-side microvascular anastomosis is a safe and reliable method and may reduce the operation time. Its clinical applicability should be further evaluated.

Lesions of the upper leg and lower trunk are the most difficult to remove, because they are often the largest ones encountered and also because they tend to extend proximally into the retroperitoneal tissues. Chyle reflux, usually associated with lymphedema of the extremity, has not been reported to be caused by lymphatic malformation. We report a case of intrapelvic retroperitoneal lymphatic malformation with an extension of gluteal-thigh soft-tissue involvement causing intractable chylorrhagia. The tumor was subtotally excised, and the defect was closed by a distally based, peninsular latissimus dorsi myocutaneous flap. The flap served both as a filling material and as a "bridge" between the residual tumor, including abnormal lymphatics, and normal lymph flow.

Potential benefits of developing modified coaptation techniques cannot be disregarded. The authors report a new coaptation technique in which the nerves are cut in an oblique fashion to increase the coaptational surface. The sciatic nerves of male Wistar albino rats were cut at an angle of 30 and 45 deg (experimental groups), and 90 deg (control group). The nerves were repaired with nine 10-0 epineural stitches. Functional and histological studies were performed at week 12 on 7 rats from the 30-deg group, 15 rats from the 45-deg group, and 7 rats from the 90-deg group. Mean sciatic function index values of walking track analysis were the following: 30-deg group, -42.4+/-15.4; 45-deg group, -44.7+/-17.9; and 90-deg group, -52.9+/-13.9 (p>0.05). The mean values of myelinated axonal counts for the 30-deg, 45-deg, and 90-deg transection groups were 196.2+/-3.7, 196.1+/- 3.7, and 176.1+/- 5.6 respectively for proximal nerve segments and 180.1+/-6.8, 178.2+/-3.8, and 114.1+/-17.3 respectively for distal samples. Both the 30-deg and 45-deg coaptational groups had a significantly lower reduction of myelinated axonal counts at the regeneration zone in comparison with the 90-deg group (p<0.01). Mean myelinated axonal diameters in the proximal nerve segments were 8.2+/-2.6 microm, 8.4+/-3.1 microm, and 8.1+/-3.2 microm respectively, and were 7.1+/-3.6 microm, 6.9+/-3.4 microm, and 6.7+/-3.4 microm respectively in the distal nerve segments (p>0.05). The oblique nerve coaptation technique may enhance nerve regeneration by enabling a larger sprouting and contact area for nerve fibers, but additional investigation by more experienced centers is needed before relying on the preliminary results of this simple modification.

Affected infants usually die perinatally. The authors present an 8-month-old female infant with manifestations of this syndrome and some additional traits including fusion of the lips, intraoral filiform bands, alopecia totalis, and posterior fusion failure of the vertebrae. The fused lips were opened by incising the fibrotic bands closing her mouth. Details of this patient and a brief review of the literature is presented.

We report on a new microvascular anastomosis technique that uses a metallic circle around the anastomotic circumference. Sutures are first passed inside the circle and tied outside and over the circle so as to stretch open the anastomotic site. By retraction of vessel ends, the circle is totally exteriorized and thus there is no contact with blood. In 48 rats, the external circle method was compared with the conventional technique for constructing end-to-end anastomosis between carotid arteries (1 to 1.2 mm) and femoral veins (1 to 1.5 mm). The external circle method proved to be superior to the conventional end-to-end technique in speed of execution for both arterial and venous anastomoses. Patency rates at the third week were significantly higher in the venous group using the metallic circle (100 percent versus 70.8 percent, p < 0.05). This new method may be applicable in clinical microvascular surgery.
