Surgical site infection (SSI) is a devastating complication in patients with neuromuscular scoliosis (NMS) undergoing posterior spinal instrumented fusion (PSIF) for progressive scoliosis. Incisional negative pressure wound therapy (INPWT) has been used in other surgical fields to reduce SSI. Our purpose was to examine the prophylactic use of INPWT after NMS surgery to decrease SSI. At a single institution, 71 consecutive patients with NMS underwent PSIF from 2015 to 2019. Starting in 2017, all patients with NMS received INPWT postoperatively until discharge. Rates of deep SSI were compared between the two cohorts of patients. Additionally, patient demographic and operative factors such as American Society of Anesthesiologists score, number of levels instrumented, need for an anterior spinal release, need for spinal fusion to pelvis, blood loss, operative time, fluoroscopy time, length of stay, and transfusion requirement were analyzed for potential influence on deep SSI. There was no significant difference in deep SSI rates between patients who received INPWT (2 of 41) and those treated with a standard postoperative dressing (2 of 30; P =1.0). Although INPWT theoretically can stabilize the wound environment and prevent deep SSI, our findings do not support this. More research is needed to evaluate the efficacy of INPWT after PSIF for NMS.

Clinical and scintigraphic findings are described in a patient in whom acute right-sided pulmonary edema developed during a treadmill exercise test. The patient's SPECT Tl-201 stress images are reviewed along with the pertinent clinical history. The development of unilateral pulmonary edema during an exercise treadmill test was demonstrated with Tl-201 imaging.
