The authors report the use of acute free flaps in head, upper and lower limb injuries. The series includes 9 clinical cases, 2 latissimus dorsi muscle and 2 fasciocutaneous radial forearm flaps for coverage and 1 flow-through cephalic antebrachial dermal venous flap for coverage and venous drainage and 4 flow-through fasciocutaneous radial mid-forearm flaps for coverage and revascularisation of the ischaemia extremities. There were no postoperative infections and no failures, confirming the reliability of this concept.  相似文献

PURPOSE: The exact distances from the cutaneous dorsal branches of the digital artery to the proximal interphalangeal joint have been established in a previous anatomic study. The aim of this report is to incorporate these anatomic data into the current way of designing the homodigital adipofascial turn-over flap for cutaneous coverage of the dorsum of the finger. Our clinical experience with this modified surgical technique to this flap is reported. METHODS: The clinical series presented here consists of 40 patients with loss of cutaneous coverage at the dorsal aspect of the middle and distal phalanges. Based on our anatomic findings the flap was designed to include at least 1 dorsal branch in its pedicle. RESULTS: The flap survival was excellent and no donor site complications were observed. CONCLUSIONS: The adipofascial turn-over arterial flap has appeared as an excellent alternative for achieving early coverage of cutaneous wounds at the dorsal aspect of middle and distal phalanges of the long fingers. This flap can be designed as an arterial flap in a predictable and reliable way based on new anatomic data on the vascularization of the dorsum of the finger.  相似文献

The limitations of the Limberg, Dufourmentel, and Webster flaps are analyzed.

Adequate coverage of dorsal finger wounds is often a challenge. The reversed cross finger subcutaneous flap to cover defects on the dorsum of phalanx constitutes an excellent option for coverage of wounds over the middle and distal phalanges of the index, middle, ring, and small fingers. It''s an easy flap and represents our first choice to cover those defects.  相似文献

Objective

The choice between local flap designs for burn reconstruction is largely shaped by aesthetic, vascularity, procedural complexity, and wound-closure considerations. However, another key consideration is how well specific local flap designs release post-burn scar contractures. This is because constant tension on wound edges can generate pathological scarring. However, the ability of specific local flap to release post-burn scar contractures is poorly understood. This question was addressed by this study of patients who underwent local flap surgery to release post-burn scar contractures.

Methods

The flap type, its original size, and the degree to which the flap extended 6 months after surgery were recorded.

Results

Of the 40 patients enrolled, 20 received an island flap and 20 received a skin-pedicled flap. The scars were most commonly located on the anterior chest, axilla, and cubital fossa, followed by the lateral chest, abdomen, thigh, and popliteal fossa. Six months after surgery, the skin-pedicled and island flaps had extended on average by 1.53- and 1.28-fold, respectively.

Conclusions

While it was technically easier to transfer island flaps to the recipient site, they released contractures less effectively than skin-pedicled flaps. The postoperative extensibility of flaps should be considered when determining which flap design is optimal for the individual patient.  相似文献

Summary Transcutaneous oxygen tension (pTcO2) in various types of flap is described and compared. Random and arterial flaps showed different pTcO2 patterns. The value of delay was shown. The results indicated the potential of the pTcO2 technique for flap research and for clinical monitoring of flap circulation.  相似文献
