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 the period stretching from June 2019 to June 2022, the repair of skin and soft tissue deficiencies encircling the ankle was accomplished in ten patients employing the posterior tibial artery perforator flap. Observing the group, 7 males and 3 females presented an average age of 537 years (meaning an age range of 33-69 years). Traffic incidents led to injuries in five cases, four cases involved injuries from being hit by heavy objects, and machinery caused one injury. Wound sizes demonstrated a range from a minimum of 5 cm by 3 cm to a maximum of 14 cm by 7 cm. The period spanning from the occurrence of the injury until the surgical intervention ranged from 7 to 24 days, with an average duration of 128 days. Lower limb CT angiography, conducted pre-operatively, yielded data enabling the generation of three-dimensional images for the perforating vessels and bones, achieved using Mimics software. With the aid of augmented reality, the above images were projected and superimposed onto the surface of the affected limb, and the skin flap was subsequently designed and resected with utmost precision. Size-wise, the flap varied between 6 cm by 4 cm and 15 cm by 8 cm. Skin grafts or direct sutures closed the donor site.
Using augmented reality (AR), the 1-4 perforator branches of the posterior tibial artery were preoperatively determined in 10 patients. The mean number of these branches was 34. Operative perforator vessel localization was remarkably similar to the pre-operative AR assessment. The extent of the separation between the two locations was found to vary from 0 mm to 16 mm, with a mean distance of 122 millimeters. The flap's successful harvest and repair aligned perfectly with the preoperative design specifications. In a testament to their resilience, nine flaps were spared from vascular crisis. Two separate cases were marked by local skin graft infections, and a single case also displayed necrosis at the flap's distal edge. This necrosis successfully healed after the dressing was changed. Marine biology The other skin grafts demonstrated remarkable resilience, resulting in the incisions healing completely by first intention. Each patient's health was observed for a span of 6 to 12 months, producing an average of 103 months of follow-up. The flap displayed a soft texture, free from the presence of scar hyperplasia and contracture. In the final follow-up assessment, the American Orthopedic Foot and Ankle Association (AOFAS) score revealed excellent ankle function in eight instances, good function in one case, and poor function in a single patient.
The preoperative assessment of posterior tibial artery perforator flap locations using augmented reality (AR) technology can minimize the risk of flap necrosis, and the surgical procedure is straightforward.
Preoperative assessment of posterior tibial artery perforator flap procedures can be enhanced by AR techniques, which aids in identifying the precise location of perforator vessels, minimizing the risk of flap necrosis and streamlining the surgical process.
The combination techniques and optimization strategies applied during the harvest process for anterolateral thigh chimeric perforator myocutaneous flaps are reviewed and summarized.
The clinical records of 359 oral cancer patients admitted between June 2015 and December 2021 were subjected to a retrospective analysis. A total of 338 males and 21 females showed an average age of 357 years, with ages ranging 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. According to the UICC TNM staging protocol, 137 cases were identified with a T-stage characteristic.

The duration of the illness spanned from one to twelve months, averaging sixty-three months. Following radical resection, free anterolateral thigh chimeric perforator myocutaneous flaps were utilized to repair the soft tissue defects, ranging in size from 50 cm by 40 cm to 100 cm by 75 cm. Four distinct steps formed the core of the myocutaneous flap harvesting process. genomic medicine Step one entailed the careful exposure and separation of the perforator vessels, predominantly those originating from the oblique and lateral branches of the descending branch. Identifying the primary perforator vessel's pedicle in step two, and pinpointing the muscle flap's vascular pedicle's origin—whether from the oblique branch, the lateral branch of the descending branch, or the medial branch of the descending branch—is crucial. The third stage in this process defines the source of the muscle flap, including the lateral thigh muscle and the rectus femoris muscle. Step four entailed determining the harvesting approach for the muscle flap, encompassing the muscle branch type, the distal type of the principal trunk, and the lateral aspect of the principal trunk.
The surgical procedure resulted in the collection of 359 free anterolateral thigh chimeric perforator myocutaneous flaps. In all subjects, the anterolateral femoral perforator vessels were seen. 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. In 94 instances, the vascular pedicle of the muscle flap emanated from the oblique branch; in 187 cases, it arose from the lateral branch of the descending branch; and in 78 cases, it stemmed from the medial branch of the descending branch. The collection of muscle flaps from the lateral thigh muscle was performed in 308 patients, coupled with 51 instances of rectus femoris muscle flap harvesting. A total of 154 muscle flaps of the muscle branch type, 78 muscle flaps of the distal main trunk type, and 127 muscle flaps of the lateral main trunk type were part of the harvest. The skin flaps' dimensions ranged between 60 centimeters by 40 centimeters and 160 centimeters by 80 centimeters; muscle flaps, conversely, spanned dimensions from 50 cm by 40 cm to 90 cm by 60 cm. In a study of 316 cases, the perforating artery exhibited an anastomosis with the superior thyroid artery, and concordantly, the accompanying vein exhibited an anastomosis with the superior thyroid vein. In 43 instances, the perforating artery interconnected with the facial artery, and its accompanying vein likewise interconnected with the facial vein. Following the operation, six cases exhibited hematoma formation, while four cases experienced vascular crisis. Of the total cases, seven survived after emergency exploration; one experienced partial skin flap necrosis, ultimately recovering with conservative dressing adjustments; and two cases presented complete skin flap necrosis, treated with pectoralis major myocutaneous flap reconstruction. The duration of follow-up for all patients ranged between 10 and 56 months, yielding a mean of 22.5 months. A pleasing presentation was afforded by the flap, and both swallowing and language functions returned to normal. The sole evidence of the procedure was a linear scar on the donor site, with no consequential effect on the thigh's performance. click here In the subsequent patient evaluation, 23 cases showed local tumor recurrence and 16 cases showed cervical lymph node metastasis. Remarkably, 382 percent of patients survived for three years, as demonstrated by the survival of 137 patients from a cohort of 359.
