Timing of presentation of the first signs of vascular compromise dictates the salvage outcome of free flap transfers.

Background: Microsurgical free tissue transfer has become a reliable technique. Nevertheless, 5 to 25 percent of transferred flaps require re-exploration due to circulatory compromise. This study was conducted to evaluate the timing of occurrence of flap compromise following free tissue transfer, and its correlation with salvage outcome. Methods: Between January of 2002 and June of 2003, 1142 free flap procedures were performed and 113 flaps (9.9 percent) received re-exploration due to compromise. All patients were cared for in the microsurgical intensive care unit for 5 days. Through a retrospective review, timing of presentation of compromise was identified and correlated with salvage outcome. Results: Seventy-two flaps (63.7 percent) were completely salvaged and 23 (20.4 percent) were partially salvaged. Eighteen flaps (15.9 percent) failed completely. Ninety-three flaps (82.3 percent) presented with circulatory compromise within 24 hours; 108 (95.6 percent) presented with circulatory compromise within 72 hours, and 92 flaps (85.2 percent) were salvaged within this period. One out of the three flaps presenting with compromise 1 week postoperatively was salvaged. Flaps presenting with compromise upon admission to the microsurgical intensive care unit had significantly lower complete salvage rates as compared with those without immediate abnormal signs (40.9 percent versus 69.2 percent, p = 0.01). Conclusions: The time of presentation of flap compromise is a significant predictor of flap salvage outcome. Intensive flap monitoring at a special microsurgical intensive care unit by well-trained nurses and surgeons allows for early detection of vascular compromise, which leads to better outcomes.

The importance of limb preservation in the diabetic population

OBJECTIVE Limb salvage in the diabetic population is complex, controversial, costly and variable throughout the world. Within the diabetic population, the indications and morbidity surrounding major leg amputation have not been well defined. RESEARCH DESIGN AND METHODS A retrospective study of the Georgetown Limb Salvage Registry was conducted to determine outcomes in diabetic patients undergoing proximal forefoot/midfoot (PF/M) amputations and to help define the indications for major leg amputation in ambulatory diabetic patients. RESULTS Of the 937 ambulatory diabetic patients identified during this time period, 808 who presented with superficial ulcers or distal forefoot disease and who did not go on to PF/M or higher amputation were eliminated. Records of 88 patients (92 limbs) in the PF/M amputation group and 25 patients in the below the knee amputation (BKA) group were reviewed (no above knee amputations were performed). At 2 years in the PF/M amputation group, 80% (70/88) of patients were still alive, 73% (68/92) of the limbs remained intact, and 64% of patients (56/88) were ambulatory. In contrast, in the BKA population at 2 years, 52% (13/25) of patients were deceased and 64% (16/25) were ambulating with a prosthetic limb (or had been ambulating at the time of death). The only statistically significant difference between these two groups was the presence of Charcot collapse and rear-foot disease in the BKA group. CONCLUSION Aggressive efforts at salvage with PF/M amputation procedures should be entertained prior to higher level amputations due to the increased morbidity and mortality evidenced.

Resource cost comparison of implant-based breast reconstruction versus TRAM flap breast reconstruction.

Relatively little has been published to date comparing the resource costs of transverse rectus abdominis musculocutaneous (TRAM) flap and prosthetic breast reconstruction. The data that have been published reflect the experience at just one medical center with a previously known clear preference for autologous breast reconstruction. The goal of this study was to compare the resource costs of TRAM flap and prosthetic reconstruction in an institution where both procedures continue to be performed using modern techniques and at a relatively equivalent frequency. All available medical records were reviewed for patients who had completed their breast reconstruction between 1987 and 1997. Records of patients who had undergone TRAM flap or prosthetic reconstruction were reviewed to compare resource costs, including hospital stay, operating room time, anesthesia time, prosthetic devices, and physician’s fees. Of 835 patients reviewed who had completed breast reconstruction, a total of 140 suitable patients were identified who had all the necessary financial information available. The patient population comprised 64 patients who received TRAM flaps and 76 patients who had undergone prosthetic reconstruction. The length of stay for the TRAM flap group, including all subsequent admissions for each patient, ranged from 2 to 24 days (mean, 6.25 days), and that for the prosthetic reconstruction group ranged from 0 to 20 days (mean, 4.36 days). Operating room time for the complete multistage reconstructive process for a TRAM flap ranged from 5 hours, 20 minutes to 12 hours, 25 minutes (mean, 7 hours, 34 minutes); with implant-based reconstruction, operating time ranged from 1 hour, 45 minutes to 8 hours, 56 minutes (mean, 4 hours, 6 minutes).
