Coverage of complex tissue defects following open cervicothoracic spine surgery with a lower trapezius island myocutaneous flap-an interdisciplinary approach.

The study design is a clinical case series. The objective of this study was to present the concept and efficacy of the lower trapezius island myocutaneous flap (LTIMF) for management of complex wound healing disorders following open cervicothoracic spine surgery. Wound healing disturbances with myocutaneous defects after open spine surgery at the cervical and upper thoracic spine are well-described complications. In severe cases, plastic reconstructive coverage is often required as a last resort. A review of all adult patients with deep wound dehiscence and tissue defects following open cervicothoracic spine surgery, who were managed with plastic surgery reconstruction using a LTIMF at our institution, was conducted. Synopses of these cases are presented. Seven patients with a mean age of 73 years ± 13 (range 50 to 89 years) were included in this case series. Six out of seven patients had instrumented posterior fusion added to their decompression. All patients were managed with a LTIMF for wound coverage. No spinal implants were removed prior to LTIMF surgery. The mean follow-up was 5.2 months (± 5.4 months). No major flap failure occurred, and all patients presented with satisfactory cosmetic results. The only minor complication was development of a sterile subcutaneous seroma in two patients, which were successfully managed by puncture and aspiration. The LTIMF is an effective and reliable salvage treatment option for spine surgery patients offering stable coverage of deep tissue defects resulting from complex wound healing disorders at the cervical and upper thoracic spine

Space-expanding flap in decompressive hemicraniectomy for stroke.

OBJECTIVE Decompressive hemicraniectomy (DCE) is the standard of care for space-occupying malignant infarction of the medial cerebral artery in suitable patients. After DCE, the brain is susceptible to trauma and at risk for the syndrome of the trephined. This study aimed to assess the feasibility of using temporary space-expanding flaps, implanted during DCE, to shield the brain from these risks while permitting the injured brain to expand. METHODS The authors performed a prospective feasibility study to analyze the safety of space-expanding flaps in 10 patients undergoing DCE and evaluated clinical and radiological outcomes. RESULTS The relatives of 1 patient withdrew consent, leaving 9 patients in the final analysis. No patients required removal of the space-expanding flap because of uncontrolled increase of intracranial pressure or infection. One patient required additional external ventricular drainage and 1 received mannitol. The mean (range) midline shift decreased from 6.67 (3-12) mm to 1.26 (0-2.6) mm after DCE with the space-expanding flap. The authors observed no cases of sinking skin flap syndrome, other complications, or deaths. One patient underwent further treatment due to infection of the reimplanted autologous bone flap. Two patients later refused cranioplasty, preferring to keep the space-expanding flap and thus avoid the potential risks of cranioplasty. CONCLUSIONS This feasibility study showed that the concurrent use of space-expanding flaps appeared to be safe in patients who underwent DCE for malignant infarction of the medial cerebral artery. Moreover, space-expanding flaps may permit patients to avoid a second surgery for reimplantation of the autologous bone flap and the risks inherent to this procedure
