摘要:

AbstractSeven patients with congenital Boyd type II pseudarthrosis of the tibia and fibula were treated with a revascularized osteocutaneous fibular graft from the contralateral side. Follow‐up ranged from 20 to 96 months (mean 67 months). All patients had previously undergone major surgery (mean three operations). Union was successful in all patients although three required further surgery. At follow‐up all patients were able to walk without external support. The results were classified as good in two cases and fair in five cases.The postoperative period was, however, often complicated by stress‐fracture and nonunion. Leg length discrepancy and valgus deformity are still unsolved problems in some cases. It seems probable that a primary reconstruction at an early age will prevent many of these subsequent problems. © 1993 Wiley‐

摘要:

AbstractFrom 1982 onwards, in Groningen, The Netherlands, we have worked on the experimental evaluation and development of microvascular prostheses in rats and rabbits. In this review article a systematic overview of this experimental work is presented and the results are discussed with regard to the literature to come to a current state of the art on (experimental) microvascular grafting with prosthetic conduits. © 1993 Wiley‐Liss I

摘要:

AbstractThis study was designed to test the ability of pre‐ and postischaemic administration of desferrioxamine (DFX), a combination of a preischaemic single passage perfusion with hypertonic citrate solution (HCA) and postischaemic administration of DFX, and pre‐ and postischaemic administration of lipoic acid (LA) to enhance the cold (0°C) ischaemia tolerance in epigastric free flaps in inbred rats. The ischaemic intervals varied between 0 and 120 hr. The area of flap survival 2 weeks after revascularisation as a percentage of original flap size was recorded as an exponent of ischaemic tolerance. None of the treatment regimens was able to increase flap area survival. Histologically, there were no major differences between the different treatment regimens. © 1993 Wiley‐L

摘要:

AbstractWe have previously shown that the epigastric flap in Dark Agouty rats, measuring approximately 6 × 4 cm with borders related to well‐defined anatomical structures, does not exhibit an all‐or‐none survival pattern. This study was designed to investigate the survival pattern of non‐revascularized epigastric flaps in three other rat strains (Sprague‐Dawley, Brown‐Norway, and Lewis). In concordance with our earlier observations, but in contrast to reports by many other groups, in none of the used strains was an all‐or‐none survival pattern observed. Survival varying from 2 to 30% (mean, 12%) of the original flap, without significant differences between the strains, was found. The locations of survival exhibited a clear pattern, probably owing to the fat pad in the subcutis and revascularisation from the recipient wound edges. © 19

摘要:

AbstractPositive results of tubulization in peripheral nerve reconstruction have been established in animals by many investigators. Clinically, tubulization by means of a venous tubulus is accepted as a reliable technique, but histological results are not known and functional analysis is limited. The aim of this investigation was to study the histological effect of venous tubuli in peripheral nerve reconstruction.In 20 rabbits the saphenous nerves were transected and anastomosed. In ten rabbits (series 1) a venous tubulus was placed around the nerve suture. In another ten rabbits (series 2) a venous tubulus was sutured over a 3 mm nerve gap. Conventional suturing was done in ten contralateral saphenous nerves (series 3, controls). Epineurial stitching was performed. The healing was studied after 3 months and after that histological analysis was performed by means of monoclonal antibody staining.The results of our experiments show that covering a nerve anastomosis with a venous tubulus did not enhance healing in comparison to the conventional end‐to‐end anastomosis, but in contrast evoked extensive fibrous tissue, thereby hampering regeneration of axons. © 1993 Wiley‐Li

摘要:

AbstractThe disfigurement of irreversible unilateral facial paralysis can be corrected by cross‐face nerve grafting in conjunction with muscle transplantation. A total of 33 patients underwent cross‐face nerve grafting using the sural nerve prior to undergoing the second stage of the procedure. Before a muscle transplant can be successfully connected to the distal end of the cross‐face nerve graft, the regenerating axons need to have grown from the contralateral facial nerve to the distal end of the nerve graft. This can be tested by the Tinel sign. A retrospective study was performed to determine the rate of growth of regenerating axons through the cross‐face nerve graft. A rate of axon growth of 1.8 mm/day was found, and also an inverse relationship between the age of the patient and the regeneration rate. These results can be used as a guide in planning patients' treatment. © 1993 Wiley

摘要:

AbstractIdeally, in phalloplasty one should aim at 1) a one‐stage procedure that can be predictably reproduced, 2) creation of a competent neo‐urethra to allow for voiding while standing, 3) return of both tactile and erogenous sensibility, 4) enough bulk to tolerate the insertion of a prosthetic stiffener, and 5) a result that is aesthetically acceptable to the patient. We consider 6) minimal scarring or disfigurement, and 7) no functional loss in the donor area further requirements for any ideal procedure. Thanks to ongoing refinements, microsurgical free flap phalloplasty techniques lead to the best results, both functionally and cosmetically. These refinements are presented and discussed, as are our experiences applying them. © 1993 Wiley‐Li

摘要:

AbstractThree weeks after radial forearm free flap phalloplasty, a 28‐year‐old female‐to‐male transsexual presented with ischaemia of the neophallus. A salvage procedure was started 7 hours after onset of ischemia. Thrombectomy of the arterial pedicle did not result in venous return of the arterial inflow. Perfusion of the flap with streptokinase restored venous return. Flap perfusion was confirmed by intraoperative direct angiography of the neophallus. Six months after this salvage procedure, the flap is doing well and tactile sensibility has occurred. © 1993 Wiley
