RESUMO
BACKGROUND: The decision between local and free tissue coverage for distal lower leg defects has long been dictated by the location and size of defects. Recent reports of distal defects treated successfully with pedicled perforator flaps demonstrate equivalent clinical outcomes; however, the complication rate can be high. The goal of this study was to evaluate the cost equivalence of free versus pedicled perforator flap to assist decision-making and guide clinical care. METHODS: The institutional database was searched for patients with acute injury over the distal lower extremity requiring free or pedicled perforator flap. Demographic, clinical, and total resource cost was gathered. Patients were matched to Gustilo-Anderson or Arbeitsgemeinschaft fur Osteosynthesefragen classification as well as size of defect and outcomes, and cost compared. RESULTS: We have included 108 free flaps and 22 pedicled perforator flaps in the study. There was no difference in complication rate between groups. Free flaps had significantly more reoperations, required longer operative time, and had longer intensive care unit (ICU) care with higher cost of surgery and overall cost than pedicled flaps. When controlling for size of defect, surgical cost remained significantly different between groups (p = 0.013), but overall cost did not. Multivariable regression analysis indicated flap type to be the primary driver of cost of surgery, while body mass index elevated the total cost. CONCLUSION: Pedicled perforator flap coverage for small to medium-sized defects (< 70 cm2) is a viable and cost-effective option for distal lower leg soft tissue reconstruction after acute traumatic injury with similar clinical outcomes and shorter operative duration and ICU stay.

BACKGROUND: Aeromonas necrotizing fasciitis (NF) causes high rates of amputation and mortality, even after aggressive surgical debridement and antibacterial therapy. This study investigated the effects of rational use of antibiotics and education by infectious disease (ID) physicians on Aeromonas NF treatment outcomes. METHODS: Retrospective review for conducted for four years (period I, without an ID physician, December 2001 to December 2005) and 15 years (period II, with an ID physician, January 2006 to March 2021). In period II, the hospital-wide computerized antimicrobial approval system (HCAAS) was also implemented. A pretest-posttest time series analysis compared the two periods. Differences in clinical outcomes, demographics, comorbidities, signs and symptoms, laboratory findings, Aeromonas antibiotic susceptibility, and antibiotic regimens were compared between the two periods. RESULTS: There were 19 patients in period I and 53 patients in period II. Patients had a lower rate of amputation or mortality in period II (35.8%) compared with period I (63.2%). Forty-four patients (61.1%) had polymicrobial infections. In the emergency room, the rate of misdiagnosis decreased from 47.4% in period I to 28.3% in period II, while effective empiric antibiotic usage increased from 21.1% in period I to 66.0% in period II. After the ID physician's adjustment, 69.4% received monotherapy in period II compared to 33.3% in period I. CONCLUSIONS: Because Aeromonas NF had a high mortality rate and was often polymicrobial, choosing an antibiotic regimen was difficult. Using the HCAAS by an experienced ID physician can improve rational antibiotic usage and clinical outcomes in Aeromonas NF.
RESUMO
BACKGROUND: The medial sural artery perforator flap is a versatile option in reconstructive microsurgery. However, most reports of this flap have been limited by sample size. This study reviews the experience of a single large-volume center using the medial sural artery perforator flap and its variants for a variety of reconstructive purposes. METHODS: A retrospective review of all patients who received the medial sural artery perforator flap reconstruction between March of 2006 and July of 2014 was performed. RESULTS: Two-hundred medial sural artery perforator flaps were used at three anatomical regions: head and neck (n = 129), upper extremity (n = 47), and lower extremity (n = 24). Flaps were transferred as free (n = 189) and pedicled (n = 11). Overall flap survival was 96 percent. Flap variants used included chimeric flap (n = 11) and dual skin paddle (n = 2). Plantaris tendon and saphenous/sural nerve graft were harvested in conjunction in 20 and seven patients, respectively. In 5 percent of the cases harvested in the conventional manner, a reliable perforator could not be found. CONCLUSIONS: The medial sural artery perforator flap is a reliable, alternative workhorse flap for nearly any small- to medium-size defect. It can be harvested as free or pedicled and the option to include multiple tissue components further expands its versatility. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Patient-reported outcome measures are an important metric in evaluating treatment efficacy of reconstructive surgery. Toe-to-hand transfer can restore vital prehensile function; however, this surgery is complex, extensive rehabilitation is required, and there are concerns about donor-site morbidity. This study longitudinally explores the benefits of this procedure, from the patient's perspective, using patient-reported outcome measures. METHODS: Twenty-three patients who underwent free toe-to-hand transfers from 2012 to 2015 were evaluated preoperatively and postoperatively using the following validated questionnaires: the Michigan Hand Outcomes Questionnaire, the 36-Item Short-Form Health Survey, and the Lower Limb Outcomes Questionnaire. Subgroup analysis was performed between dominant and nondominant reconstructed hands. RESULTS: Mechanism of injury was crush in 83 percent; the remainder sustained cutting, avulsion, and burn injuries. Thirty-four toes were transferred: nine great toes, 20 second toes, and five third toes. Michigan Hand Outcomes Questionnaire results showed significant improvement in overall activities of daily living, work, aesthetics, and patient satisfaction (p < 0.05). The results of the 36-Item Short-Form Health Survey showed significant improvements in physical and emotional roles (p < 0.05). The Lower Limb Outcomes Questionnaire showed no deterioration of foot function (p = 0.55). Subgroup analysis showed significant improvement in patient-reported outcome measures for patients undergoing dominant hand reconstruction but no difference between thumb reconstruction and finger-only reconstruction. CONCLUSIONS: Patient-reported outcome measures demonstrate the significant utility of toe-to-hand transfer procedures in both functional and psychosocial domains in that there are relatively greater benefits in reconstructing the dominant hand, and that donor-site morbidity is well tolerated. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: The medial sural artery perforator (MSAP) flap has become increasingly popular because it is thin and pliable for small to moderate defect soft tissue reconstruction. Furthermore, chimeric MSAP flap, which includes a skin paddle and a separated piece of medial gastrocnemius muscle, allowed more freedom for flap insetting, especially in 3-dimensional defect reconstruction. Here we describe our experience regarding this clinical application. PATIENTS AND METHODS: From 2007 to 2016, 14 male patients (average age, 46.9 ± 14.4 years) who received either a free or pedicled chimeric MSAP flap were included. Of these 14 patients, 7 received this flap for reconstruction in the head and neck, 2 in the upper extremities, and 5 in the lower extremities. Demographic data were collected and analyzed, and a literature review was performed. RESULTS: Ten patients received free chimeric MSAP flap, and 4 received the pedicled type. Thirteen of the 14 flaps (92.6%) survived, and 1 failed 2 days later owing to venous insufficiency. Venous congestion-related partial loss occurred in another case. CONCLUSIONS: The chimeric MSAP flap is a good alternative for deep space obliteration or reconstruction of adjacent but separate defects in both free and pedicled flap design. Donor site morbidity is limited. However, the perforator needs to be mobilized carefully to prevent postoperative venous compromise.
