摘要:

AbstractA venous clot model in rats was used to compare the ability of locally infused thrombolytic agents to lyse clots. Urokinase and a combination of streptokinase and human plasminogen (Thrombolysin) proved to be equally effective in lysing clots. In comparison, streptokinase alone was not as effective a thrombolytic agent in this model.

摘要:

AbstractThe histopathologic changes caused by microvascular anastomosis were studied in 178 femoral arteries of rats. While in all vessels the tissue surrounded by the suture loops at the anastomosis showed the strangulating effect of the suture with the process of repair being evident on the endothelial and adventitial surfaces, there were certain differences in the changes between patent and thrombosed vessels in the areas adjacent to the anastomosis. A study of the incidence of various tissue changes showed that endothelial integrity is important for patency of the anastomosis.

摘要:

AbstractIn this article, four cases of free fibular osteocutaneous flap transfer are reported. The advantages of the bone‐attached flap, its microsurgical anatomy, and its design and method of isolation are discussed in detail. Postoperative follow‐up showed success in all four cases with satisfactory functional recov

摘要:

AbstractVascularized grafting with segments of fibula was performed in four men with aseptic necrosis of the femoral head. The patients were restricted to relatively young individuals in whom the necrosis seemed to be confined to two‐thirds or less of the femoral head and in whom the outer shell of the femoral head appeared relatively well preserved. The operative technique is described, and the interim results from follow‐up ranging from one year, two months to three years, eight months are reported. Three of the four hips became asymptomatic after surgery with x‐ray films showing no progression of the necrosis or deformity. In one hip, however, mild pain, bony absorption, and some progression of the deformity persisted. Although the final results in these four cases remain to be seen, vascularized fibular grafting will find a place in the treatment of early avascular necrosis of the femoral

摘要:

AbstractA patient who required excision of a large basal cell carcinoma was left with a scalp defect measuring 23 cm × 23 cm, associated with an underlying bony defect of 18 cm × 16 cm with a similar dural defect. Simultaneous reconstruction of all three layers was performed using a large free latissimus dorsi flap, titanium strips, and lumbar fascia. A satisfactory cosmetic and functional result was obtained using this techniqu

摘要:

AbstractA critical laboratory evaluation of transcutaneous PO2monitoring and tissue pH monitoring in lower abdominal island flaps based on the superficial inferior epigastric vessels in rabbits revealed that transcutaneous PO2values correlate poorly with tissue survival under circumstances of decreased arterial inflow. The inability of the transcutaneous PO2monitor to accurately predict viability of the flaps in this study is attributed to physiologic changes in the microcirculation and not to instrument error. Tissue pH was, in all instances, a reliable index of the perfusion status of the flaps.

摘要:

AbstractIn ten rabbits the nerve branch to the left rectus femoris muscle was prolonged to the contralateral side by a nerve graft. Three months later the distal end of the transplant was connected to the transsected nerve branch to the right rectus femoris muscle. Nerve biopsies were taken from the muscle nerve, the nerve graft at the time of grafting and from the distal end of the nerve graft immediately before nerve suture in the second operation. Six months after the second operation the final assessment of muscle function and of the histology of the muscle and of the muscle nerve was performed. The functional results of the rectus femoris muscle reinnervated by a crossover nerve graft ranged between 6% and 56% of a normal standard muscle and seemed to be insufficient to justify a clinical use for muscle transplant reinnervation in the extremities. The histological findings also confirmed the basic possibility of elongating a motor nerve by nerve grafts, but the second nerve suture, the interposition of a long nerve graft, and the obviously changed reflex system probably caused a moderate and unpredictable muscle function.

摘要:

AbstractTotal arterialization of the liver appears to be a promising clinical method in preventing or reducing encephalopathy after shunting. A new technique for achieving total arterialization of the liver in rats is described and illustrated. This method is fast, simple, and associated with a high patency rate, even in the hands of relatively inexperienced microsurgeons. It can be recommended as an experimental model for additional studies in rats.
