11/547. Amputated lower limbs as a bank of organs for other organ salvage. Aggressive modern technologies have made it possible to attempt limb salvage in even the most extreme cases. However, it is imperative to remember that prolonged salvage attempts may lead to devastating complications. The decision-making is more problematic in patients with bilateral severely injured mangled lower limbs. In such a case, protocols like the MESS are no longer valid because of the implications of bilateral amputation. In these rare cases, we use a multi-team approach and modern micro-surgical reconstructive techniques in attempting to salvage at least one of the lower limbs. We present here our experience in six patients with bilateral mangled lower limbs where an amputated limb was the source of "spare parts" for the salvage of the contralateral limb. In each of the cases, after evaluation and planning, the harvesting of the required tissues (including skin, muscle, bone, nerve and blood vessels) from the amputated leg was performed and simultaneously, a reconstruction of the contralateral severely injured limb was done. These cases emphasize the importance of modern trauma care, not only the ability to treat multiply traumatized patients, but also the capability to execute sophisticated techniques during the acute phase of treatment with maximal cooperation between teams from different disciplines.

12/547. Variants in the deep circumflex iliac artery: clinical considerations in raising iliac osteocutaneous free flaps. Anomalies of the deep circumflex iliac artery do occur, although they are uncommon. Recently, two cases of these anomalies were encountered by the authors during elevation of iliac osteocutaneous free flaps. In the first case, the deep circumflex iliac artery was absent, and the nourishing artery of the flap was instead connected to the large iliolumbar artery. In the second case, the ascending branch, deriving from the deep circumflex iliac artery as usual, had a separate takeoff directly from the external iliac artery, and provided blood supply to the overlying skin as a musculocutaneous perforator that transversed the three muscle layers of the abdominal wall. This ascending branch was assumed to be a duplication of the deep circumflex iliac artery. Ascertaining the divergence of the deep circumflex iliac artery from the external iliac artery before beginning to raise the flap, and careful dissection of the artery, are essential for minimizing problems in flap transfer.

13/547. Transcranial doppler detection of fat emboli. BACKGROUND AND PURPOSE: The fat embolism syndrome (FES) is characterized by the simultaneous occurrence of pulmonary and neurological symptoms as well as skin and mucosal petechiae in the setting of long-bone fractures or their surgical repair. Its pathophysiology is poorly understood, and effective treatments are lacking. We present 5 patients with long-bone fractures in whom in vivo microembolism was detected by transcranial Doppler. methods: Five patients with long-bone fractures were monitored with transcranial Doppler for microembolic signals (MESs) after trauma. Two patients also had intraoperative monitoring. A TC-2020 instrument equipped with MES detection software was used. Detected signals were saved for subsequent review. Selected signals satisfied criteria defined previously and were categorized as large or small. RESULTS: Cerebral microembolism was detected in all 5 patients and was transient, resolving within 4 days of injury. Intraoperative monitoring revealed an increase in MESs during intramedullary nail insertion. The characteristics of MESs after injury varied among patients, with large signals being more frequent in the only patient with a patent foramen ovale. CONCLUSIONS: Cerebral microembolism after long-bone fractures can be detected in vivo and monitored over time. These findings may have potential diagnostic and therapeutic implications. ( info) |
14/547. gas gangrene in a patient with severe haemophilia A. The haemophilia patient tends to live a more protected life than his normal counterpart, this is particularly so in underdeveloped and developing countries where due to poor health infrastructure, financial constraints and nonavailability of factor concentrates, patients quickly learn that they need to live a protected life. Under such circumstances, gas gangrene seems to be a very unusual infection for this group of patients. We report here a 25-year-old male with severe haemophilia who developed gas gangrene due to inadequate medical management following a road traffic accident. Subsequently, his affected limb was salvaged by conservative therapy. A literature search failed to reveal any reports of similar patients in the English literature. ( info) |
15/547. Primary reconstruction of traumatic bony defects using allografts. We retrospectively reviewed 207 patients suffering from traumatic bone defect who had been treated at our institution between 1973 and 1993. Three types of traumatic bone defects were identified: I, minor; II, major cortical; III, major articular. Each type was further subdivided into: A, open injury; B, closed injury. The proposed treatment modality of each type was included within each classification. Types II and III posed the greatest difficulties in management. However, massive bone allografts can be successfully used in these situations, even in the early phases of treatment, but only given specific prerequisites. ( info) |
| A patient is presented who developed the Compartment Syndrome, following blunt trauma to the lower limb. A "fibulectomy-fasciotomy" was performed. This allowed restoration of normal peripheral circulation of the limb but failed to prevent ischaemic necrosis developing in the anterior tibial, peroneal and posterior tibial compartments. compartment syndromes in the lower limb are discussed, with a view to their early recognition and management.

17/547. Ossification in the rectus sheath following free rectus flap. Heterotopic ossification (HO) is a rare complication of laparotomy wounds. In this report, we describe an unusual presentation of ossification within the closed sheath following the harvest of a free rectus flap for lower limb reconstruction. Of specific interest to this case is that access to the rectus was gained through a lower transverse approach. Furthermore, the extremities of this incision were utilised for harvest of cancellous bone from the iliac crests. Given that one explanation for HO is intraoperative seeding it is of note that no problem was encountered in the wound intimately associated with the bony disruption. ( info) |
18/547. Free flap to the arteria peronea magna for lower limb salvage. A 36-year-old woman sustained an amputation of her right leg at the thigh level and a degloving injury of her left foot and ankle region in an accident during a suicide attempt. Primarily, her left foot was covered with a split skin graft, resulting in a soft-tissue defect at the medial malleolus and at the calcaneus bone. Reconstruction was planned with a free latissimus dorsi muscle flap. Preoperative examinations revealed an arteria peronea magna with a hyperplastic peroneal artery solely providing arterial blood supply to the foot. The arteria peronea magna divided into two branches proximal to the upper ankle joint, replacing the dorsal pedis artery and the medial plantar artery. Tibial posterior and tibial anterior arteries were hypoplastic-aplastic. Microvascular end-to-end anastomoses of the flap vessels to the medial branch ("medial plantar artery") of the arteria peronea magna and its concomitant vein at the medial malleolar bone level were successfully performed. The postoperative course was uneventful. Four weeks postoperatively, the patient started walking assisted by a prosthesis on her right thigh stump. This experience demonstrates that even in a case of arteria peronea magna, free flap surgery for lower limb salvage is a reliable and worthwhile method. ( info) |
19/547. Widely split latissimus dorsi muscle flaps for reconstruction of long soft-tissue defects in lower extremities. Although the latissimus dorsi is one of the largest and longest muscles in the human body, it is still sometimes inadequate for reconstruction of a soft-tissue defect of extensive length and dimension. Eight patients with such lower limb defects were treated with latissimus dorsi muscles split into two hemiflaps sequentially linked, one after the other like a chain. Six transfers were completely successful, one required reexploration for arterial occlusion, and two hemiflaps had a partial loss that could be managed by touching up the skin graft. The average split sequential-link muscle was 42 cm in length. Although two patients had a partial loss, we consider that the widely split single latissimus dorsi muscle can still be used reliably to reconstruct a long slender defect, or two separate, longitudinally located, medium-sized defects in the same leg.
