Postoperative infections should be comprehensively controlled in the context of infection control, rather than as activities of individual surgeons. We started a surgical site infection (SSI) surveillance program in 2009 in which prophylactic measures for preventing SSIs were applied. These measures were as follows : 1) screening for nasal carriage of methicillin-resistant Staphylococcus aureus ; 2) dental checks and oral screening ; 3) antibiotic prophylaxis in the intra- and postoperative period ; 4) control of glucose levels to ≤160 mg/dl in the immediate postoperative period ; and 5) early removal of surgical drain. After the introduction of prophylactic measures, we reexamined SSI surveillance and added the following prophylactic measures at the beginning of 2011 : 6) data concerning SSI and compliance with prophylactic measures for all surgical and ward staff were published monthly, and the Infection Control Team (ICT) and surgeons performed weekly ward visits to assess SSIs ; 7) recommendations were made for wearing two pairs of gloves and surgical hoods to cover the hair, scalp, ears and neck ; and 8) collaboration with diabetologists was implemented to control glucose levels in diabetics. We compared incidences of SSI in cardiovascular surgery from the periods before (469 cases, Group B) and after (118 cases, Group A) introduction of the additional prophylactic measures. Clinical characteristics of patients in each group did not differ significantly. Operative time was significantly shorter in Group A (400±116 min) than in Group B (434±145 min). Compliance with antibiotic prophylaxis in the intraoperative period improved progressively from 93% in Group B to 99% in Group A. Compliance with control of glucose levels to ≤160 mg/dl on postoperative day 1 improved progressively from 71% in Group B to 81% in Group A. Duration of drain placement was significantly shorter in Group A (2.9±1.8 days) than in Group B (3.6±2.9 days). Incidence of SSI decreased significantly from 6.0% in Group B to 0.8% in Group A. Revision of preventive measures based on the results of surveillance and enhancement of cooperation between the ICT and surgeons could help to decrease the incidence of SSI.

We herein report a case of a ruptured vertebral artery dissecting aneurysm involving the origin of the posterior inferior cerebellar artery that was treated using the stent-jack technique. After parent artery occlusion of the distal vertebral artery, stenting of the posterior inferior cerebellar artery was performed. Further coiling was needed because distal vertebral artery recanalization occurred due to transformation of the coil mass. The stent-jack technique for a ruptured vertebral artery dissecting aneurysm involving the origin of the posterior inferior cerebellar artery is effective; however, careful attention to recanalization after stenting is needed due to transformation of the coil mass.

We present the case of a 72-year-old man with constrictive pericarditis due to tuberculous pericarditis, who was treated with the waffle procedure via left anterolateral thoracotomy. The preoperative catheterization study showed the dip-and-plateau pattern, and the echocardiographic study shown the thickened pericardium and dilatation impairment. The surgery was able to be performed without cardiopulmonary bypass. The thickened pericardium was abraded with a Harmonic Scalpel. The waffle procedure was effective in this patient. The postoperative course was good, with improvement of NYHA status and cardiac pressure study results. We suggest that this procedure is useful for the patients with constrictive pericarditis.

STUDY DESIGN: Retrospective study. PURPOSE: To investigate the relationship between preoperative total spinal sagittal alignment and the early onset of adjacent segment degeneration (ASD) after single-level posterior lumbar interbody fusion (PLIF) in patients with normal sagittal spinal alignment. OVERVIEW OF LITERATURE: Postoperative early-onset ASD is one of the complications after L4–L5 PLIF, a common surgical procedure for lumbar degenerative disease in patents without severe sagittal imbalance. A better understanding of the preoperative characteristics of total spinal sagittal alignment associated with early-onset ASD could help prevent the condition. METHODS: The study included 70 consecutive patients diagnosed with lumbar degenerative disease who underwent single-level L4–L5 PLIF between 2011 and 2015. They were divided into two groups based on the radiographic progression of L3–L4 degeneration after 1-year follow-up: the ASD and the non-ASD (NASD) group. The following radiographic parameters were preoperatively and postoperatively measured: sagittal vertebral axis (SVA), thoracic kyphosis (TK), lumbar lordosis, pelvic tilt, and pelvic incidence (PI). RESULTS: Eight of the 70 patients (11%) experienced ASD after PLIF (three males and five females; age, 64.4±7.7 years). The NASD group comprised 20 males and 42 females (age, 67.7±9.3 years). Six patients of the ASD group showed decreased L3–L4 disc height, one had L3–L4 local kyphosis, and one showed both changes. Preoperative SVA, PI, and TK were significantly smaller in the ASD group than in the NASD group (p <0.05). CONCLUSIONS: A preoperative small SVA and TK with small PI were the characteristic alignments for the risk of early-onset ASD in patients without preoperative severe sagittal spinal imbalance undergoing L4–L5 single-level PLIF.
