AI Article Synopsis

  • Multi-detector row computed tomography (MDCT) allows visualization of blood vessels in the anterolateral thigh (ALT) flap, crucial for certain surgeries.
  • * This report explores the use of augmented reality (AR) to improve the harvesting process of the ALT flap in a cancer patient undergoing tongue reconstruction.
  • * The AR technology accurately predicted the location of blood vessels during surgery, leading to a successful flap transfer without complications in the patient at a 6-month follow-up.

Article Abstract

Multi-detector row computed tomography (MDCT) makes it possible to visualize the peripheral perforators of the anterolateral thigh (ALT) flap. However, to transfer the preoperative MDCT angiography data to the operative field requires effective techniques. In this report, we describe an application of augmented reality (AR) technology to harvest the anterolateral thigh flap. A 36-year-old female presented with a T2N2 squamous cell carcinoma of the lateral tongue. The patient underwent hemiglossectomy and microsurgical reconstruction using the left ALT flap. Three dimensional (3D) images the vascular image, vascular with muscles and vascular with outline of the thigh ware prepared. Then these images were exposed to an AR device. The location of the perforator was determined using the 3D vascular image on AR. The intraoperative location of the cutaneous perforator corresponded with the predicted location which was confirmed using the AR technique. A 6 × 15 cm left ALT flap was transferred to the defect. Microsurgical anastomosis was performed on the left superior thyroid artery and the internal jugular vein. There were no complications during the postoperative course. At the 6-month follow-up, the patient showed no evidence of flap and donor site complications. Our experience suggests that AR technology may effectively support the transfer of MDCT angiography images onto surgical sites.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

Chimeric anterolateral thigh flap for reconstruction of complex defects in oral cancer: a report of three cases.

It is crucial to reconstruct extensive soft tissue defects following oral cancer resection to restore both function and aesthetics. Single anterolateral thigh flaps may not suffice for large defects. This report highlights the use of chimeric flaps, which feature multiple paddles with individual perforators, to reconstruct large intraoral and extraoral defects, adapting to wide defects, and covering areas with extensive tissue damage.

We present the case of a 36-year-old male patient with a posttraumatic composite defect of the lower two-thirds of the anterior aspect of the left leg with exposed necrotic tibia in an old, neglected type 3b fracture of the tibia of 9-month duration. The options for definitive soft-tissue cover include microvascular free tissue transfer and cross-leg flaps. In trauma cases, the surrounding tissue is usually damaged, and the recipient vessels are frequently implicated, ruling out the use of a microvascular free flap.

A 21-year-old male laborer sustained bilateral degloving injury of the hands with multiple digital amputations and devascularized digits. After X-rays, preliminary debridement was done, when digital amputations were completed, including index ray amputation on both sides. The next day, two anterolateral thigh (ALT) flaps and one second toe transfer were done to restore coverage in the palm and the web and reconstruct the lost thumb.

Background: Complex lower extremity defects are difficult to cover and often require multiple free tissue transfers. Chimeric anterolateral thigh free flaps (ALTF) and peroneal artery perforator free flaps (PAPF) have been designed specifically as an alternative for reconstruction with arterial end-to-side (ETS) anastomosis. We aimed to assess our institutional experience with this technique and to define its role in complex lower extremity reconstruction.
