One hundred forty-seven flaps in 135 consecutive patients undergoing microvascular transplantation were monitored using a miniature Doppler ultrasonic probe. Using a modification of a technique described previously by Swartz, the probes were secured to the outflow vein of the flap with Vicryl mesh. Twenty instances of thrombosis or spasm were detected in 16 patients, and all flaps were salvaged (100 percent). There were four false positive and no false negative results. This probe allows for safe, continuous monitoring of flap blood flow, which permits the rapid detection and hence rapid treatment of postoperative complications. Our experience suggests that a significant improvement in the salvage rate of microvascular transplants may be attainable with the use of this device.

The long-term results and costs of bone transport and flap coverage strongly support complex limb salvage in this patient population.

Every attempt should be made at scalp replantation when the patient is stable and the parts salvageable. Larger avulsion defects had higher success rates after replantation than smaller defects (<300 cm(2) ), with the superficial temporal artery and vein most commonly used for recipient vessels (P = 0.0083). Microvascular tissue transfer remains a mainstay of treatment for scalp defects, with LD-based flaps, demonstrating excellent versatility for a range of defects.

The aesthetic outcome of dorsal hand reconstruction is dependent on flap choice, with statistically significant differences in revision surgeries and aesthetics among flap types.
