RESUMEN
INTRODUCTION: Retained wound swabs although classified as a 'never event' and well documented in many surgical specialties are uncommon in spinal surgery. The aim of this article is to highlight the perioperative circumstances of an incident of a retained surgical swab and present a prevention protocol, in an attempt to eliminate its incidence. CASE REPORT: The perioperative management of a 53-year-old male undergoing spinal surgery in whom a surgical swab was retained is reported. In addition to existing safety procedures such as the World Health Organization checklist, a Retained Surgical Swab-Prevention Protocol was implemented in our hospital and is presented to eliminate the occurrence of this 'never event' occurring again. CONCLUSION: Retained surgical swabs or instruments are rare in spinal surgery occurring mostly in the lumbar spine, during emergency and prolonged procedures in patients with high body mass index. Maintaining a high index of suspicion and utilising a prevention protocol will prevent further harm to the patient.

AIMS: Morphological assessment of neointimal tissue using optical coherence tomography (OCT) is important for clarifying the pathophysiology of in-stent restenosis (ISR) lesions. The aim of this study was to determine the impact of OCT findings on recurrence of ISR after various types of percutaneous coronary intervention (PCI) including plain old balloon angioplasty (POBA), paclitaxel-coated balloon (PCB) dilatation, and drug-eluting stent (DES) implantation. METHODS AND RESULTS: Between June 2008 and August 2013, we performed PCI for 428 ISR lesions in 379 patients using POBA (78 lesions, POBA group), PCB dilatation (202 lesions, PCB group), and DES implantation (148 lesions, DES group). Morphological assessment of neointimal tissue at the minimum lumen area site to determine restenotic tissue structure (homogeneous, heterogeneous, or layered type) using OCT was performed. We examined the association between tissue structure and midterm results including ISR and target lesion revascularization (TLR) rates. The patients were 308 men and 71 women with a mean age of 68.9 ± 9.4 years. The mean follow-up period was 211 ± 40 days. ISR and TLR rates of lesions with a homogeneous structure were significantly higher in the POBA group than in the PCB group (ISR: 54.8 vs. 19.1%, P < 0.001; TLR: 38.7 vs. 10.6%, P < 0.001) and DES group (ISR: 54.8 vs. 19.6%, P = 0.002; TLR: 38.7 vs. 10.7%, P = 0.005), whereas there were no differences in ISR and TLR rates between the three groups in lesions with a heterogeneous structure. CONCLUSION: Morphological assessment of ISR tissue using OCT might suggest favourable types of PCI for ISR lesions.
