1/27. Salvage of the lower leg using a reversed long free fibular flap.The advantages of end-to-side anastomoses have been well documented in microvascular surgery. The vessels of the fibular flap do not usually permit end-to-side anastomosis to recipient vessels in the proximal part of the lower leg because the pedicle length of the free fibular flap is usually too short. Therefore, vein grafts are used to elongate the vessels. If a harvested long free fibular flap that is used to bridge a massive defect of the tibia is reversed and placed into the medullary cavity of the tibia, the flap vessels can be anastomosed, using the end-to-side technique, to the recipient vessels without vein grafts in the distal part of the lower leg. Thus, the flap artery (the peroneal artery) fills in a retrograde fashion. The patient reported was reconstructed with a reversed long free fibular flap. The postoperative period was uneventful. The patient can stand and walk with a protective shoe 2 years postoperatively.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/27. Recognition and significance of pulmonary bone embolism.embolism of bone marrow to the lungs is a quite frequent finding after trauma but transport and deposition of solid bone is rarely seen, which may simply be because pulmonary calcifications are not recognized as bone fragments. We report on three patients with embolism of bone spicules to small lung arteries of about 0.5 mm in diameter which were plentiful in two of the patients on postmortem examination. However, the true nature of the emboli was only recognizable after decalcification of lung tissues. It appears that trauma occurring in a septic bone lesion has the greatest chance to provoke bone embolism. The bone spicules do not usually occlude vessel lumina and thus do not severely disturb the blood circulation in the lungs. The bone fragments become covered by endothelium and can remain recognizable for months or even years.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
3/27. Reverse venous outflow of a free fibular osteocutaneous flap: a salvage procedure.The authors report 2 patients with a massive bony defect of the tibia due to chronic osteomyelitis. They reconstructed the defect using a free vascularized fibular osteocutaneous flap. Unfortunately, venous insufficiency was diagnosed 24 hours postoperatively. The previous anastomosed veins were promptly explored. The peroneal veins of the vascularized fibular bone graft were noted to be full of thrombi. After thrombectomy, the vessels became very fragile and broke down easily. It was impossible to achieve normal antegrade venous outflow from the previous vein of the donor graft; however, they found that distal runoff of the peroneal vein achieved a reverse venous outflow from the donor graft. The great saphenous vein was dissected and reanastomosed to achieve adequate venous drainage. This procedure may offer an alternative treatment for a flap with venous insufficiency.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
4/27. Cross-leg pedicled free scapular flap for neuropathic foot ulcer: case report.A case is reported of the treatment of a chronic neuropathic ulcer on the lateral aspect of the foot with osteomyelitis. Extensive debridement and free scapular flap transfer were performed. Because the leg had only one patent vessel, the anterior tibial artery, which was unsuitable for anastomosis, the vascular anastomosis of the flap was performed to the posterior tibial vessel of the contralateral leg, which was used as a termporary carrier. The vascular pedicle was divided after 3 weeks, and the flap survived completely. This case report extends the indications of the cross-leg free flap for complex defects on a single-vessel foot.- - - - - - - - - - ranking = 0.6keywords = vessel (Clic here for more details about this article) |
5/27. Blood supply of hemipelvectomy flaps: the anterior flap hemipelvectomy.In posterior flap hemipelvectomy, preservation of the gluteus maximus with the flap guarantees its viability regardless of the level of ligation of the iliac vessels. In anterior flap hemipelvectomy with the quadriceps femoris attached to the flap, the dominant blood supply is through the lateral femoral circumflex branches of the profunda vessels, which is sufficient to maintain the flap.- - - - - - - - - - ranking = 0.4keywords = vessel (Clic here for more details about this article) |
6/27. Free gluteal artery perforator flap with a short, small perforator.The introduction of supermicrosurgery has led to the development of a new gluteal perforator flap nourished only by a musculocutaneous perforator of the superficial gluteal artery system. This flap has a perforator that is short (3-4 cm in length) and small (less than 1 mm). The successful transference of a free gluteal perforator flap for the coverage of soft-tissue defects in the foot and face in two patients is described in this article. With this flap, deeper and longer dissection for a pedicle vessel is unnecessary, flap elevation time is shorter, thinning of the flap with primary defatting and creation of an adiposal flap with customized thickness for tissue augmentation are possible, the donor site is in a concealed area with minimal donor site morbidity, and application of the flap as a scarred flap for previous operations in the gluteal region is possible. The disadvantages of this flap are necessity of dissection for a smaller perforator and of anastomosis of small-caliber vessels of less than 1.0 mm.- - - - - - - - - - ranking = 0.4keywords = vessel (Clic here for more details about this article) |
7/27. Retroperitoneal hematoma after spinal anesthesia with the paramedian approach.We present a case of a patient who developed a retroperitoneal bleeding after spinal anesthesia using 22-gauge Quincke needle, with the paramedian approach. Two attempts were needed to accomplish the block. Four hours later the patient complained of back pain radiating to her left calf, with weakness of the quadriceps muscle. Computed tomography revealed a large retroperitoneal hematoma from bleeding lumbar artery. angiography failed to demonstrate the vessel. The patient was transfused with packed red blood cells and recovered gradually. She had normal coagulation tests throughout the event. IMPLICATIONS: We describe a case of a large retroperitoneal hematoma after the placement of an uneventful spinal block. The patient required four units of packed red blood cells despite having normal coagulation profiles throughout the event. The diagnosis and treatment of retroperitoneal hematoma are discussed.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
8/27. Microvascular anastomosis through the tibial tunnel: a new technique in free-tissue transfer to the leg.Free-tissue transfer to a severely traumatized leg has a high rate of vascular complications. We present three successful cases using a new technique of microvascular anastomosis through the tibial tunnel. Because of the unavailability of anterior tibial artery due to posttraumatic vascular disease, donor vascular pedicles were passed posterior to the tibia through the tibial tunnel and anastomosed to the posterior tibial artery or its branch in an end-to-end fashion. The flaps survived perfectly, without any vascular complication. This technique represents a safe route, and the shortest route, to an expected anastomosis point. Our technique is indicated especially in cases with a single-vessel leg.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
9/27. limb salvage of infected diabetic foot ulcers with free deep inferior epigastric perforator flaps.Soft-tissue reconstruction of the feet in diabetic patients with angiopathy, sensorial neuropathy, and immunopathy is a complicated problem. Until the mid-1980s, chronic foot ulcers in diabetic patients were treated conservatively, because flap surgery was regarded as too risky. However, in recent years, early debridement and flap coverage have become popular reconstructive methods for diabetic foot wounds. Several flap donor sites are available, depending on the nature of the defect. The deep inferior epigastric artery perforator (DIEP) flap is a relatively new flap that developed as a modification of the transverse rectus abdominis muscle (TRAM) flap. It provides a large amount of skin and subcutaneous tissue, without the donor-site morbidity of the ordinary TRAM flap. Furthermore, using the DIEP flap avoids the loss of major vessels. In this study, we report on the successful use of the DIEP flap in four cases of diabetic foot ulceration.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
10/27. Gastrocnemius muscle flap of both heads on a single vascular pedicle.We present a case of a muscle flap of both heads of gastrocnemius on a single vascular pedicle for reconstruction of a tibial defect. The flap was based on the medial sural vessels alone. The vascular supply to the lateral head was achieved through the anastomotic vessels along the gastrocnemial raphe.- - - - - - - - - - ranking = 0.4keywords = vessel (Clic here for more details about this article) |
