ABSTRACT
Objective:To investigate the removal of ALTPF pedicled with the lateral branch of the descending branch of the lateral femoral circumflex artery and its application in wound repair.Methods:From January, 2019 to March, 2021, 32 cases of limb wounds were repaired with ALTPF pedicled with the lateral branch of the descending branch of the lateral femoral circumflex artery, including 25 males and 7 females. The age ranged from 21 to 63 years, with an average of 34 years. Injury mechanism: there were 12 cases of traffic accident injury, 8 cases of machine injury, 6 cases of heavy object crushing injury and 6 cases of chronic infectious wound. The area of soft tissue defect was 8.2 cm × 6.3 cm-18.6 cm × 11.2 cm. There were 25 cases of direct suture and 7 cases of free skin grafting. All patients who needed flap repair underwent CTA and high-frequency CDU before operation to judge the approximate direction of the lateral branch of the descending branch of the lateral femoral circumflex artery and the position of the perforating branch. All patients were followed-up regularly for 3 - 13 months, with an average of 11 months.Results:All patients who underwent free flap surgery had no vascular crisis and the flap survived smoothly. At the last follow-up, the appearance of the flap was beautiful without bloating and there were no complications in the donor area.Conclusion:Compared with the traditional ALTPF, the perforator flap of the lateral branch of the descending branch of the anterolateral femoral artery is relatively simple, which can replace the traditional ALTPF to a certain extent, and is worthy of popularization and application in clinic.
ABSTRACT
Objective: To explore the clinical application of vascular augmentation of an extra-long latissimus dorsi flap through an intercostal artery in limb wound repair. Methods: Between January 2016 and December 2017, 5 patients with limb wounds were treated with the extra-long latissimus dorsi flaps. The vascular augmentation of the extra-long latissimus dorsi flap through the intercostal artery was applied during the operation. There were 4 males and 1 female, with an average age of 45.8 years (range, 43-59 years). The time from post-traumatic admission to flap repair was 7-25 days (mean, 12.3 days). The causes of injury included machine injury in 2 cases, traffic accident in 2 cases, and roller crush injury in 1 case. The wounds were located at the anterior of upper limb in 3 cases, the posterior of upper limb in 1 case, and the posterior of leg in 1 case. The size of wounds ranged from 26 cm×8 cm to 38 cm×10 cm. The size of the latissimus dorsi flap ranged from 36 cm×6 cm to 43 cm×7 cm. The size of the muscle flap ranged from 36 cm×10 cm to 43 cm×15 cm. The donor sites were closed directly. Results: The distal flap necrosis occurred in 1 case and healed after symptomatically treatment. The other flaps survived completely. The wounds and incisions at donor sites healed by first intention. All patients were followed up 8-18 months with an average of 14.9 months. At last follow-up, the flaps had satisfactory appearances, soft textures, and function of sweating. Conclusion: Application of vascular augmentation of the extra-long latissimus dorsi flap through the intercostal artery in repair of limb wound can reduce the incidence of distal flap necrosis and achieve satisfactory effectiveness.
ABSTRACT
Objective To investigate the clinical effect of using pedicled flap to reconstruct skin and soft tis-sue defect after resection of sarcoma around extremities joint. Methods Retrospectively analysis 103 cases of sar-coma around extremities joint who was treated from June, 2012 to June, 2017 and used the pedicled fasciocutaneous flaps or pedicled musculocutaneous flaps to reconstruct the defect after sarcoma resection. There were 61 males and 42 females, with a mean age of 52.3 (14-82 ) years old. Among these patients, there were 32 initial diagnosis, 30 had been resected in other units, and 41 recurrent tumor. There were 13 patients that tumor around wrist:reconstructed by radial wrist upper branch fasciocutaneous flap, dorso-ulnar flap based on supracarpal perforator, and posterior in-terosseous artery flap. Eight patients with tumor around elbow: reconstructed by lateral arm flap and media arm flap. Eight patients with tumor around shoulder: reconstructed by latissimus dorsi musculocutaneous flap and lateral tho-racic flap. Fourteen patients with tumor around hip: rectus femoris musculocutaneous flap, tensor fascia lata musculo-cutaneous flap, and posterior thigh fasciocutaneous flap. Sixteen patients that tumor around knee:reconstructed by an-terolateral low leg flap, and sural calf fasciocutaneous flap. Forty-four patients that tumor around ankle: reconstructed by saphenous neuro-veno-fasciocutaneous flap, sural neuro-veno-fasciocutaneous flap, lateral supramalleolar flap, and medial plantar flap. The defect area after tumor resection were:3 cm ×4 cm-18 cm×25 cm. After surgery, observe the situation and fitness of flap, complication, joint mobility, and tumor recurrence and metastasis. Results Allflaps survived except 6 died or partial died, with a survival rate of 94.2％, of which dead flap were replaced by a new flap or covered by free skin graft. Infection occurred in 4 cases (2 in donor site and 2 in recipient site), were cured by dressing and antibiotic. Except for 12 cases dropped, all rest 91 cases were followed-up by 33 months on average (1-5 years), flaps' shape and texture were good, without swollen and fester, and fit well. Superficial sensibility of direct fasciocuta-neous flaps and musculocutaneous flaps were normal, protective sensation of reverse fascial flaps were recovered. The mobility of affected joint show no difference compared with the other side. No ulcer occurred on flaps of plantar and but-tocks, that helps normal sit position and gait. There were 17 recurrences and 32 metastasis occurred, 21 patients died so far. There was a statistical difference between recurrent cases with first shot(10.3％) second widely resection(11.5％) and recurrent resection(30.6％)(P<0.05). Conclusion Using pedicled flap to reconstruct skin defect after the resection of sarcoma around extremities joint, can get good clinical result, with simple and reliable operation. It is worth to popularize.
ABSTRACT
Objective This experiment aimed at exploring a limb wound guard to avoid the clothing being stained by bleeding or drainage on llmb wounds, keep them dry and clean inside, enable the limbs to move conveniently and protect the wounds untouched so as to increase patients' sense of security. Methods 180 surgical patients with limb wounds were randomly divided into two groups, 94 cases in the observation group who used limb wound guards and 86 patients in the control group who did not. The treatment effect and comfort degree were compared between the two groups by X2 test and Ridit analysis. Results Statistically sig-nificant differences between the two groups could be observed in the per capita frequency of clothing replace-ment, the wound infec- tion rate, the average days of hospital stay and patients" comfort degree. Conclusions The results indicate that using limb wound guards can prevent the clothing from being polluted by wound exu-clarion, keep them dry and clean inside, make the patients feel comfortable and reduce wound infection, facili-tate the activities of the injured limbs, reduce patients" fatigue and discomfort, protect the wound untouched and therefore, increase pa-tients' sense of security.
