Compromised Flap Salvage With Closed Incision Negative Pressure Therapy Under Real-Time Indocyanine Green Fluorescence Assessment.

BACKGROUND: Skin flap transfer is a commonly used technique by surgeons; however, compromised blood flow may result in flap ischemia and necrosis. We describe the use of closed incision negative pressure therapy (ciNPT) to help manage skin flap reconstructions with indocyanine green fluorescence angiography (ICG-FA) to assess perfusion of the flaps before and after ciNPT. METHODS: Three female and 5 male patients underwent various skin flap reconstructions, including local flaps, pedicled flaps, and propeller flaps, for wound defects related to trauma, infection, or cancer. After flap setting and suturing, ciNPT (-125 mm Hg) was applied to the closed incision for 7 days. Perfusion was assessed using ICG-FA before applying ciNPT and again at 24 hours later. The Shapiro-Wilk test and Wilcoxon signed rank test were used in statistical analysis. RESULTS: Initial postoperative survival was observed for all skin flaps; however, 1 flap failed after 2 weeks due to uncontrolled infection. The remaining 7 flaps healed well without any surgical revision. All patients were initially determined to have impaired flap perfusion; however, skin flap perfusion was significantly higher after ciNPT than before ciNPT in each case (P = 0.012). CONCLUSIONS: This study showed good healing outcomes for skin flap reconstructions without complications, despite the fact that each flap had compromised flap perfusion to some extent during the surgery. This case series is novel in that it used laser-assisted ICG-FA to provide a real-time assessment of skin flap perfusion before and after ciNPT.

Experience of Surgical Treatment for Occipital Migraine in Taiwan.

PURPOSE: Refractory migraine surgery developed since 2003 has excellent results over the past 10 years. According to the pioneer of migraine surgery, Dr. Bahman Guyuron, 5 major surgical classifications of migraines are described in the field of plastic surgery, namely, frontal migraine, temporal migraine, rhinogenic migraine, occipital migraine, and auriculotemporal migraine. In this study, we present the preliminary surgical results of the occipital migraine surgery. MATERIALS AND METHODS: A total of 22 patients with simple occipital migraines came to our outpatient clinic for help from June 2014 to February 2015. Thirteen cases were excluded owing to ineligibility for operation or other reasons. The patients who concurrently experienced other types of migraines were precluded even if they received combined migraine surgery. Therefore, 9 simple occipital migraine cases were enrolled in this study. Migraine severity was evaluated by uniform questionnaires to identify the source of migraine. Neurolysis was performed under general anesthesia, with the patient in a prone position. Postoperative conditions were evaluated at the second, fourth, sixth, and eighth weeks by posttreatment questionnaires. RESULTS: Of all the 9 patients, 5 experienced single-sided migraines of greater occipital nerve origin (2 left-sided and 3 right-sided cases). Two patients had bilateral migraines of greater occipital nerve origin, and unilateral right lesser occipital nerve origin was noted in one patient. The last patient had right-sided migraines of greater and lesser occipital nerve origin. As a result in the follow-up, a response rate greater than 90% was documented, and complete resolution was observed in 2 patients. Drug doses were reduced more than 50% in the remaining patients. The overall efficacy of occipital migraine surgery in this study was 88.8% (8/9 cases). CONCLUSION: Some patients with migraine are good candidates for surgical resolution with appropriate and meticulous selection. Similar to what is observed in Western countries, the migraine surgery is promising and could provide a better quality of life to selected refractory migraine patients in Taiwan.
