A 77-year-old woman was admitted to our hospital because of low-grade fever and lightheadedness 7 days after the removal of a carious broken tooth. Neurological examination revealed disturbed consciousness and meningeal sign with mild ophthalmoplegia. Cerebrospinal fluid examination showed elevated levels of polymorphonuclear cells and enhanced magnetic resonance imaging revealed a left masticator space abscess. On the basis of these findings, the diagnosis was meningitis complicated by a masticator space abscess. Although her symptoms were ameliorated after the administration of antibiotics, her consciousness deteriorated accompanied by bilateral total ophthalmoplegia. Enhanced head computed tomography revealed a filling defect of the superior orbital veins with enhancement of the cavernous sinus, suggesting cavernous sinus thrombosis. After the addition of anticoagulants to antibiotic therapy and surgical drainage of the abscess, she recovered without residual neurological impairment. Because cavernous sinus thrombosis is potentially life-threatening, early diagnosis and initiation of appropriate therapy are extremely important.

Spinal cord injury is a dreaded and serious complication of operative procedures on the descending aorta. To avoid this serious complication, 53 patients underwent somatosensory evoked potential (SEP) monitoring during operations on the aorta which required cross-clamping of the descending aorta. 38 patients whose SEPs were kept normal during and after operations did not develop spinal cord injury. Among the 14 patients who developed both abnormal decrease in amplitude and elongation of peak latency, 13 lost their SEPs during aortic cross-clamping. Peripheral nerve ischemia seemed to be the cause of those abnormalities in 8 to whom cross-clamping was given to the abdominal aorta. Inadequate perfusion of the distal aorta was suspected in 6 to whom cross-clamping was given to the descending thoracic aorta. In these cases, however, SEP monitoring was not specific in differentiating spinal cord ischemia from peripheral nerve ischemia. Spinal cord injury was noted in only one of the 6 patients. The remaining one patient developed complete loss of SEP and spinal cord injury on the first postoperative day despite the well preserved SEP during the operation. Since this patient underwent flow reversal and thromboexclusion method for the dissecting aneurysm, gradual thrombotic occlusion of the important radicular arteries draining to spinal cord might have resulted delayed appearance of the spinal cord injury. In conclusion, SEP monitoring is the reliable method to detect the spinal cord ischemia which might be developed during cross-clamping of the descending aorta. However, this method bears limitation in its clinical application due to the following reasons. First, intraoperative SEP monitoring cannot predict delayed occurence of spinal cord injury. Secondly, this method cannot detect the qualitative extent of ischemia of spinal cord and the safe range of the cross-clamp time.

A 13-year-old girl with congenital mitral incompetence had undergone valvoplasty using the De Vega technique at age 5. The patient was referred by the pediatric department due to recurrence of mitral incompetence. Transesophageal echocardiography indicated regurgitation from A2 and P3, mild mitral leaflet tethering and left ventricular dilatation. Intraoperative findings showed valvular agenesis of the posterior leaflet around P3. No leaflet prolapse was observed at A2, but leaflet P2 had fallen to the left ventricular side compared with leaflet A2, thereby inducing regurgitation due to coaptation gap. In a procedure similar to folding plasty, leaflet P3 was folded down and sutured to the annulus extending up to the posteromedial commissure. This technique not only controlled regurgitation at P3 but also improved the coaptation between A2 and P2. Annuloplasty was conducted using a 28-mm Physio-ring. Folding plasty may be an effective surgical option for patients with congenital mitral incompetence because a broad valve orifice area can be maintained because there is no need for annular plication.

STUDY DESIGN: A retrospective case review. PURPOSE: To assess the clinical and radiographic outcomes and identify the predictive factors associated with poor clinical outcomes after lumbar spinous process-splitting laminectomy (LSPSL) for lumbar spinal stenosis (LSS). OVERVIEW OF LITERATURE: LSPSL is an effective surgical treatment for LSS. Special care should be taken in patients with degenerative lumbar scoliosis (DLS). METHODS: A consecutive retrospective case review of patients undergoing LSPSL for LSS with a minimum 2-year follow-up was performed. Mild DLS and mild degenerative spondylolisthesis (DS) were included in the study. The Japanese Orthopedic Association (JOA) score and recovery rate were reviewed. Poor clinical outcome was defined as a recovery rate <50% using Hirabayashi's method. RESULTS: A total of 52 patients (mean age, 72 years) met the inclusion criteria and had a mean follow-up of 2.6 years (range, 2-4.5 years). The preoperative diagnosis was LSS in 19, DS in 19, and DLS in 14 cases. The mean JOA score significantly increased from 14.6 to 23.2 at the final follow-up. The overall mean recovery rate was 60.1%. Thirteen patients (25%) were assigned to the poor outcome group. A higher rate of pre-existing DLS was observed in the poor outcome (poor) group (good, 15%; poor, 62%; p=0.003) than in the good outcome (good) group. None of the patient factors examined were associated with a poor outcome. A progression of slippage > or =5 mm was found in 8 of 24 patients (33%) in the DS group. A progression of curvature > or =5degrees was found in 5 of 14 patients (36%) in the DLS group. The progression of scoliosis and slippage did not influence the clinical outcome. CONCLUSIONS: The clinical and radiographic outcomes of LSPSL for LSS were favorable. Pre-existing DLS was significantly associated with poor clinical outcome.

Perivalvular leakage (PVL) is one of the serious complications of mitral valve replacement. Between 1991 and 2006, 9 patients with mitral PVL underwent reoperation. All of them had severe hemolytic anemia before surgery. The serum lactate dehydrogenase (LDH) level decreased from 2,366±780 IU/l to 599±426 IU/l after surgery. The site of PVL was accurately defined in 7 patients by echocardiography. PVL occurred around the posterior annulus in 3 patients, anterior annulus in 2, anterolateral commissure in 1, and posteromedial commissure in 1. The most frequent cause of PVL was annular calcification in 5 patients. Infection was only noted in 1 patient. In 4 patients, the prosthesis was replaced, while the leak was repaired in 5 patients. There was one operative death, due to multiple organ failure, and 4 late deaths. The cause of late death was cerebral infarction in 1 patient, subarachnoid hemorrhage in 1, sudden death in 1, and congestive heart failure (due to persistent PVL) in 1. Reoperation for PVL due to extensive annular calcification is associated with a high mortality rate and high recurrence rate, making this procedure both challenging and frustrating for surgeons.

The purpose of this study is to evaluate the efficacy of hochuekkito for late-onset hypogonadism (LOH) patients. We administered hochuekkito 7.5 g/day for 8 weeks to 47 patients with LOH whose AMS scale was more than 27. We assessed the patients' symptom change with the AMS, SHIM, SDS, BDI, and SF-36. We measured their endocrine profiles and levels of their cytokines. At the end of study, 31 of 47 patients were evaluable. No significant difference in subjective symptoms was seen with any questionnaire after 8 weeks hochuekkito administration. However, hochuekkito significantly increased free testosterone and decreased ACTH/cortisol levels. Thus we believe hochuekkito is beneficial for the treatment of LOH.

Methods: This study included 229 patients (107 men and 122 women; mean age, 68.9 years) who received one or two levels of MISTLIF, and the patient’s age, gender, disease, paralysis, preoperative physical functions, duration of symptom(s), and surgery-associated factors (waiting for surgery, number of surgical levels, surgical time, and intraoperative blood loss) were studied. Radiographic characteristics and clinical outcomes such as Oswestry Disability Index (ODI) scores and Visual Analog Scale (VAS; 0–100) ODI scores for low back pain, leg pain, and numbness were studied. One year following surgery, patient satisfaction (defined as satisfaction for surgery and for present condition; 0–100) was assessed using VAS and its relationships with investigation factors were examined. Results: The mean VAS scores of satisfaction for surgery and for present condition were 88.6 and 84.2, respectively. The results of multiple regression analysis showed that preoperative adverse factors of satisfaction for surgery were being elderly (β =-0.17, p =0.023), high preoperative low back pain VAS scores (β =-0.15, p =0.020), and postoperative adverse factors were high postoperative ODI scores (β =-0.43, p <0.001). In addition, the preoperative adverse factor of satisfaction for present condition was high preoperative low back pain VAS scores (β =-0.21, p =0.002), and postoperative adverse factors were high postoperative ODI scores (β =-0.45, p <0.001) and high postoperative low back pain VAS scores (β =-0.26, p =0.001). Conclusions According to this study, significant preoperative low back pain and high postoperative ODI score after surgery are linked to patient unhappiness.

We report a case of aortic arch replacement and extraanatomic bypass from a branched graft to both bifemoral arteries in a patient with aortic dissection complicated by ischemia in the lower extremities. A 61-year-old woman was found to have thrombosed type II aortic dissection by enhanced computed tomography (CT). Because she had no clinical symptoms, we chose conservative pharmacotherapy. A year later, she suddenly felt severe back pain and dyspnea. CT demonstrated type IIIb aortic dissection. She developed lower extremity ischemia because the true lumen in the abdominal aorta was severely compressed by the false lumen. Two weeks after onset, we planned a bilateral axillo-femoral bypass because the right lower limb ischemia had worsened, with severe pain. However, CT showed ascending aortic dissection. Hence, emergency graft replacement of aortic arch was required. A T-shaped graft was anastomosed to the bilateral femoral arteries, and was used as a delivery line during cardiopulmonary bypass. Although distal anastomosis of the arch was constructed only to the true lumen, leg ischemia persisted. Therefore, the T-shaped graft was connected to the branched graft used for antegrade systemic perfusion. We used INVOS as an indicator of intraoperative lower limb ischemia, which was useful for judging whether or not revascularization of lower extremity was achieved. After the operation, the bypass graft was patent, and ischemia in the lower extremities disappeared.
