A study of the accuracy and consistency of augmented reality (AR) in identifying the perforating vessels of the posterior tibial artery when repairing soft tissue lesions of the lower limbs with a posterior tibial artery perforator flap approach.
In ten cases, the posterior tibial artery perforator flap was employed to address defects in the skin and soft tissues adjacent to the ankle between June 2019 and June 2022. The group included 7 male and 3 female individuals, with an average age of 537 years; a range in age of 33-69 years. In five cases, the injury was a result of a traffic accident; in four cases, bruising from a heavy object was the cause; and in one, a machine was responsible. Wound sizes demonstrated a range from a minimum of 5 cm by 3 cm to a maximum of 14 cm by 7 cm. The timeframe between the moment of injury and the subsequent operation extended from 7 to 24 days, averaging 128 days. The lower limbs were subjected to CT angiography prior to surgery, and the generated data enabled the reconstruction of three-dimensional models of perforating vessels and bones within Mimics software. The skin flap was designed and precisely resected, after the above images were projected and superimposed onto the surface of the affected limb using augmented reality technology. Flap sizes ranged between 6 cm by 4 cm and 15 cm by 8 cm. Skin grafting or direct sutures were used to repair the donor site.
AR technology was used to locate, preoperatively, the 1-4 perforator branches of the posterior tibial artery in 10 patients; a mean of 34 perforator branches was observed. Preoperative AR assessments of vessel location largely mirrored the findings during the surgical placement of perforator vessels. Spatial separation between the two sites was observed to vary between 0 and 16 mm, presenting a mean distance of 122 mm. In accordance with the preoperative plan, the flap was successfully collected and mended. The nine flaps escaped the perils of vascular crisis without incident. Local skin graft infections affected two patients, and one case demonstrated necrosis in the distal edge of the flap. This necrosis was ameliorated after the dressing was changed. synthetic genetic circuit Miraculously, the remaining skin grafts survived, and the incisions healed without complication, conforming to first intention. Patients were tracked throughout a period of 6 to 12 months, with a mean follow-up duration of 103 months. No signs of scar hyperplasia or contracture were observed in the soft flap's structure. The final follow-up assessment, utilizing the American Orthopaedic Foot and Ankle Society (AOFAS) scale, revealed eight cases of excellent ankle function, one case of good function, and one case of poor function.
AR-guided preoperative planning of posterior tibial artery perforator flaps can help determine the location of perforator vessels, reducing the likelihood of flap necrosis, and facilitating a simpler operation.
To reduce the risk of flap necrosis and simplify the surgical procedure, AR technology can precisely determine the location of perforator vessels during the preoperative planning of posterior tibial artery perforator flaps.

In order to encapsulate the methodologies and optimization strategies inherent within the harvest procedure for the anterolateral thigh chimeric perforator myocutaneous flap, a summary is presented.
Retrospectively examined clinical data from 359 oral cancer patients admitted between June 2015 and December 2021 revealed insights. The group consisted of 338 males and 21 females, exhibiting an average age of 357 years, distributed across an age range between 28 and 59 years. 161 cases of tongue cancer were reported, adding to 132 cases of gingival cancer and 66 cases of buccal and oral cancer. The UICC's TNM staging methodology revealed 137 cases featuring T-stage characteristics.

The disease manifested over a period of one to twelve months, averaging sixty-three months in duration. Free anterolateral thigh chimeric perforator myocutaneous flaps were employed to address the soft tissue defects resulting from the radical resection, specifically those with dimensions varying between 50 cm by 40 cm and 100 cm by 75 cm. The myocutaneous flap's collection was largely categorized into four procedural steps. immune diseases In step one, the perforator vessels, principally those arising from the oblique and lateral branches of the descending branch, were meticulously exposed and dissected. In step two, the procedure involved isolating the main trunk of the perforator vessel pedicle and determining the muscle flap's vascular pedicle's origin, which might be the oblique branch, the lateral branch of the descending branch, or the medial branch of the descending branch. Step three involves pinpointing the source of the muscle flap, specifically the lateral thigh muscle and the rectus femoris. The muscle flap's harvesting method was specified during step four, taking into account the muscle branch type, the distal portion of the main trunk, and the lateral portion of the main trunk.
359 anterolateral thigh chimeric perforator myocutaneous flaps, free, were procured. Anterolateral femoral perforator vessels were demonstrably present in each instance. In 127 instances, the perforator vascular pedicle of the flap originated from the oblique branch, while the lateral branch of the descending branch provided the source in 232 cases. The oblique branch supplied the vascular pedicle to the muscle flap in 94 cases, while the lateral branch of the descending branch supplied the pedicle in 187 cases, and the medial branch of the descending branch supplied it in 78 cases. A surgical technique for collecting muscle flaps used the lateral thigh muscle in 308 cases and the rectus femoris muscle in 51 cases. Muscle flaps harvested included 154 cases of branch muscle type, 78 cases of distal main trunk type, and 127 cases of lateral main trunk type. Noting a difference in dimensions, skin flaps were found to have sizes ranging from 60 cm by 40 cm to 160 cm by 80 cm, and the muscle flaps showed a variation from 50 cm by 40 cm up to 90 cm by 60 cm. The superior thyroid artery was found to anastomose with the perforating artery in 316 instances, and the superior thyroid vein likewise anastomosed with the accompanying vein. Forty-three cases demonstrated an anastomosis between the perforating artery and the facial artery, along with an anastomosis between the accompanying vein and the facial vein. Six instances of hematoma occurrence and four occurrences of vascular crises were noted post-operation. After emergency exploration, 7 cases were saved successfully; in one, a partial skin flap necrosis was observed, which healed with conservative dressing changes. Two other cases experienced complete necrosis of the skin flap, necessitating repair with a pectoralis major myocutaneous flap. Across all patients, the follow-up period extended from 10 to 56 months, averaging 22.5 months. We found the flap's appearance to be satisfactory, and the swallowing and language functions had returned to full functionality. A linear scar was the exclusive residual mark at the donor site, not causing any significant impact on the functionality of the thigh. PMA activator datasheet Subsequent monitoring revealed 23 patients with local tumor recurrence and 16 patients experiencing cervical lymph node metastasis. A three-year survival rate of 382 percent (137 out of 359) was observed.
The harvest procedure of the anterolateral thigh chimeric perforator myocutaneous flap benefits significantly from a clear and adaptable classification of key points, leading to more optimized protocols, improved safety, and reduced surgical difficulty.
The harvest process of anterolateral thigh chimeric perforator myocutaneous flaps can be optimized in its entirety by employing a clear and adaptable classification of key elements, thus increasing surgical safety and lowering the operational difficulty.
