Assessing the precision and robustness of augmented reality (AR) procedures for pinpointing perforating vessels of the posterior tibial artery in treating soft tissue defects of the lower limbs using the posterior tibial artery perforator flap method.
Ten patients, during the period from June 2019 to June 2022, benefited from ankle skin and soft tissue repair through the application of the posterior tibial artery perforator flap. There comprised 7 males and 3 females; their average age was 537 years (a mean 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 dimensions varied from 5 cm by 3 cm to 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. In order to prepare for the surgery, lower limb CT angiography was performed, and the obtained data was used to create three-dimensional images of the perforating vessels and bones, utilizing Mimics software. Via augmented reality, the above images were projected and superimposed onto the surface of the affected limb, which allowed for the precise design and resection of the skin flap. There was a range in the flap's size, starting at 6 cm by 4 cm and extending up to 15 cm by 8 cm. The donor site was either directly sutured or restored with a skin graft.
Ten patients underwent preoperative localization of the 1-4 perforator branches of the posterior tibial artery (mean, 34 perforator branches) by means of an augmented reality technique. The operational positioning of perforator vessels demonstrated a substantial alignment with the preoperative AR data. Spatial separation between the two sites was observed to vary between 0 and 16 mm, presenting a mean distance of 122 mm. The flap was successfully and precisely harvested and repaired, replicating the preoperative design. Despite the potential for vascular crisis, nine flaps remained unaffected. 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. consolidated bioprocessing The survival of the other skin grafts was accompanied by the first-intention healing of the incisions. Patients were monitored for 6-12 months, yielding an average follow-up time of 103 months. The flap's softness was not compromised by the absence of scar hyperplasia or contracture. At the conclusion of the follow-up period, the American Orthopaedic Foot and Ankle Society (AOFAS) score demonstrated excellent ankle function in eight patients, good function in one patient, and poor function in one patient.
To reduce flap necrosis risk and simplify the operation, augmented reality (AR) facilitates precise preoperative localization of perforator vessels in posterior tibial artery flap procedures.
Utilizing augmented reality (AR) in preoperative planning for posterior tibial artery perforator flaps, the precise location of perforator vessels can be determined, leading to a lower risk of flap necrosis, and a simpler surgical approach.
A summary of the various techniques for combining elements and optimizing the harvest strategy of anterolateral thigh chimeric perforator myocutaneous flaps is presented.
A review of clinical data from 359 patients diagnosed with oral cancer and admitted between June 2015 and December 2021 was performed retrospectively. Among the study participants, 338 individuals identified as male, alongside 21 females, with an average age of 357 years, and an age range spanning 28 to 59 years. 161 cases of tongue cancer were reported, adding to 132 cases of gingival cancer and 66 cases of buccal and oral cancer. A review of TNM staging data from the Union International Cancer Center (UICC) showed 137 cases of T-stage cancer.

A period of one to twelve months encompassed the duration of the illness, with a mean of 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. Dactinomycin cell line 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. To successfully proceed with the procedure, step two mandates the isolation of the main trunk of the perforator vessel pedicle and the determination of the origin of the muscle flap's vascular pedicle—either the oblique branch, the lateral descending branch, or the medial descending branch. To ascertain the origin of the muscle flap, encompassing the lateral thigh muscle and rectus femoris, is step three. To ascertain the harvest method for the muscle flap, factors such as the branch type of the muscle, the distal type of the main trunk, and the lateral type of the main trunk were evaluated in step four.
Free chimeric perforator myocutaneous flaps from the anterolateral thigh were gathered: 359 in total. Without exception, the anterolateral femoral perforator vessels were observed in each of the instances reviewed. Among the cases studied, 127 involved the oblique branch as the source of the flap's perforator vascular pedicle, and the remaining 232 cases utilized the lateral branch of the descending branch. The oblique branch provided the vascular pedicle for the muscle flap in 94 cases; the lateral branch of the descending branch served as the origin in 187 cases; and the medial branch of the descending branch supplied the pedicle in 78 cases. In 308 cases, the lateral thigh muscle was used to harvest muscle flaps, while the rectus femoris muscle was used in 51 cases. From the harvest, 154 specimens were of the muscle branch type, 78 of the main trunk distal type, and 127 of the main trunk lateral 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. Of the 316 cases examined, the perforating artery's anastomosis with the superior thyroid artery was observed, and the corresponding vein anastomosed with the superior thyroid vein. In a sample of 43 cases, an anastomosis of the perforating artery with the facial artery was observed, and this was accompanied by an anastomosis of the associated vein with the facial vein. After the operation, a total of six patients demonstrated hematoma formation and four developed vascular crises. Seven cases were successfully salvaged during emergency exploration. One case experienced partial necrosis of the skin flap, healing following conservative dressing changes. Two additional cases demonstrated complete necrosis of the skin flap, necessitating repair using a pectoralis major myocutaneous flap. Patients were observed for follow-up periods of 10 to 56 months, yielding a mean duration of 22.5 months. We found the flap's appearance to be satisfactory, and the swallowing and language functions had returned to full functionality. Following the procedure, the only indication of intervention was a linear scar at the donor site, without any appreciable effect on thigh function. Empirical antibiotic therapy Following the initial treatment, 23 patients demonstrated local tumor recurrence, while 16 patients exhibited cervical lymph node metastasis during the follow-up period. Of the 359 patients, 137 survived for three years, representing an impressive 382 percent survival rate.
