RESUMO
Objective:To investigate the clinical effect of free anterolateral thigh perforator flap(ALTPF) in reconstruction of temporal scalp defect after blood circulation reconstruction surgery for moyamoya disease.Methods:From May 2020 to July 2022, 7 patients with scalp defect after revascularisation of moyamoya disease were treated in Department of Hand and Foot Microsurgery, Henan Provincial People’s Hospital (People’s Hospital of Zhengzhou University). The patients were 4 males and 3 females, aged 33-59 years old, at 43 years old in average. There were 5 defects in left tempus and 2 in right tempus. The sizes of scalp defect were 4.5 cm × 5.5 cm-7.5 cm × 9.5 cm. Debridement and VSD management were primarily performed. After wounds were stabilised, ultrasound location of perforator vessels of ALTPFs was performed. Having confirmed that the perforator vessels were suitable for the surgical requirements, flap transfers were then performed. The descending branch of the lateral femoral circumflex artery was end-to-side anastomosed with the superficial temporal artery, and the descending branch of the lateral femoral circumflex vein was end-to-end anastomosed with the superficial temporal vein. Postoperative follow-up was conducted through outpatient clinic visits, telephone and WeChat reviews. Appearance, texture of ALTPFs and the flap donor sites were observed in follow-ups. Comparisons of the changes of nervous system before and after surgery were made. Cognitive function of the patients was assessed with the Mini Mental State Examination (MMSE), together with the Activities of Daily Living (ADL) .Results:All 7 flaps survived. One flap had vascular compromise 6 hours after surgery, and was rectified after surgical intervention. All the patients were included in the postoperative follow-up for 7-33 (average 19) months. All flaps had good appearance with soft texture. There was no obvious difference in colour comparing with the skin around the recipient region. The donor sites healed well without hypertrophic scar. Examinations of nervous system of the patients were found the same as that before surgery. Using Manual Muscle Testing (MMT), the average limb muscle strength of the patients was 4 before surgery and 4 after surgery, without change; Using the Ashworth assessment scale, the average preoperative and postoperative limb muscle tension in this group of patients was 1, without change; The Berg balance scale was used to evaluate the patient's balance function, with an average score of 42 before surgery and 42 after surgery, without any changes; There was no change in limb sensation before and after surgery; Using the MMSE, the average preoperative score and postoperative score of this group of patients were 25 points, without any change. Using the modified Barthel index scoring standard, the average preoperative score for this group of patients was 75 points, and the average postoperative score was 79 points, and the ADL of the patient had improved to various levels.Conclusion:Reconstruction of scalp defect with free ALTPF after revascularisation of moyamoya disease has obvious advantages, such as it closes the wound quickly, prevents infection and achieves a good appearance. This surgical procedure can produce a good clinical effect.
RESUMO
Objective:To retrospectively analyze clinical characteristics, flora distribution characteristics, and antimicrobial sensitivity of type 2 diabetic patients with back abscess.Methods:The clinical data of patients with type 2 diabetes mellitus and back abscess were collected from Endocrinology Department of Henan Provincial People′s Hospital from October 2017 to April 2020. The results of bacterial culture and drug sensitivity test were analyzed, antibiotics were given to treat infection, incision and debridement of abscess were performed according to the situation of abscess, drainage of abscess cavity or continuous negative pressure suction was given when necessary, and the clinical outcome was recorded.Results:A total of 12 type 2 diabetic patients with back abscess were included. The average size of their abscess was(150.3±101.2)cm 2, with over 100 cm 2 in 8 cases(66.7%). Among the 12 patients, 11 patients underwent bacterial culture and drug sensitivity analysis. The positive rate of culture was 100%, and all of them were Staphylococcus aureus, with 10 cases of methicillin-susceptible Staphylococcus aureus(MSSA)and 1 case of methicillin-resistant Staphylococcus aureus(MRSA). MSSA strains were 100% sensitive to oxacillin, vancomycin, linezolid, levofloxacin, moxifloxacin, tetracycline, tegecycline, rifampicin, amoxicillin/clavulanic acid, amikacin, and teicoplanin. Both MSSA and MRSA strains were sensitive to vancomycin, linezolid, rifampin, amikacin, and teicoplanin. The wound of all patients was healed, with 100% cure rate and(35.8±34.0)days of average healing time. Conclusion:The back abscess in type 2 diabetic patients is characteristic of rapid progress, huge abscess, and difficult to treat, which should be treated early, incised and debrided timely. Staphylococcus aureus is its single pathogen and it is helpful to select the antibiotics empirically.
RESUMO
Objective:To investigate the effect of free anterolateral thigh perforator flap on repair of bone exposure of diabetic foot ulcer.Methods:From Sep. 2016 to Dec. 2019, free anterolateral thigh perforator flap was used to repair 19 cases of diabetic foot ulcer with bone exposure. The area of the flap ranged from 5.0 cm×7.0 cm to 10.0 cm×16.0 cm. The donor site of the flap was sutured directly. The patients were followed up regularly by outpatient and telephone.Results:18 of the 19 cases survived completely, in one case, most of the flap were necrotic, healed after second stage skin grafting; 5 flaps developed edema due to low albumin, and healed after stitches removal, dehydration, albumin supplement and secondary suture and antibiotic replacement. Through 6 to 24 months of follow-up study we concluded that flap transfer could functionally and morphologically repair wounds with soft tissue defect and infection.Conclusion:Free anterolateral thigh perforator flap is effective in repairing diabetic foot ulcer and can effectively reduce disability rate.
RESUMO
Objective:To investigate the surgical method and clinical effect of one-stage repair of soft tissue defects of dorsum of hand and multiple fingers by using the polyfoliate conjoined anterolateral thigh perforator flap (ALTP) .Methods:From November, 2015 to September, 2019, 9 cases of soft tissue defects of dorsum of hand and multiple fingers were treated, including 8 males and 1 female. The average age was 32 years old. Causes of injury: 4 cases of thermal injury, 3 cases of strangulation injury, and 2 cases of traffic accident injury. Location of injury: 7 cases of right hand, 2 cases of left hand. Three cases of dorsum of hand with 1st-4th fingers, 3 cases with 2nd-5th fingers, 2 cases with 2nd-4th fingers, and 1 case with 3rd-5th fingers; All with bone, joint and tendon exposure. There were 6 cases with fracture or joint dislocation. All of them had no obvious defect of bone and joint. VSD was used to cover them after debridement. According to the shape and size of the wound, all flaps were designed to repair the soft tissue defect as the polyfoliate conjoined ALTP. The flap size was 7 cm×13 cm-12 cm×17 cm. Regular outpatient, telephone and Wechat follow-up were carried out to evaluate the flap survival, appearance, color elasticity, donor scar, sensory recovery, finger function recovery and patient satisfaction.Results:Nine cases of flap survived well. The average followed-up time was 12 (6-18) months. The postoperative followed-up revealed satisfactory shapes of the flaps, protective touch and recovery of functions. The donor site had good healing and no effect on function. In the last followed-up, according to the trial criteria for function evaluation of upper limbs by Chinese Society of Hand Surgery, 5 cases were excellent, 3 cases were good, and 1 case was fair. The hand function recovered well and returned to work and daily life on average 6 weeks after operation.Conclusion:The polyfoliate conjoined ALTP can repair the soft tissue defect of hand dorsum with multiple fingers at one stage, and the flap is in good shape. There is no need to divide the fingers. It is one of the ideal methods to repair the soft tissue defect of hand dorsum.
