The patient was an 82-year-old woman. For dysphagia scrutiny, upper gastrointestinal endoscopy and biopsy of a submucosal tumor of the midthoracic esophagus were performed. The patient was urgently admitted to the Department of Gastroenterology for examination and treatment. After admission, enhanced CT showed a descending thoracic aortic aneurysm (DTA) pressing on the esophagus. On the third day of hospitalization, the patient suffered massive hematemesis and went into shock, and emergency thoracic endovascular aortic repair (TEVAR) was performed with resuscitation based on the diagnosis of esophageal perforation of the DTA. The patient was weaned from the ventilator by tracheotomy without cerebrospinal complications and left the intensive care unit on the seventh postoperative day. One month after surgery, a CT scan showed that the DTA had almost disappeared and that the esophageal compression had been released. The patient was managed with antibacterial therapy and nutritional support other than oral intake and was discharged home 7 months after surgery without stent graft infection or mediastinitis. The usefulness of TEVAR for ruptured descending thoracic aortic aneurysms has been reported in many cases. However, in patients with an aortoesophageal fistula (AEF), esophagectomy is required after TEVAR to control infection, and the mortality rate of this disease is high. We report a case in which infection were controlled by antibacterial therapy and nutritional management other than oral intake after TEVAR and the patient survived.

A retrospective observational study was performed. We investigated the relationships between skeletal muscle mass, bone mineral density (BMD), and trabecular bone score (TBS) in patients with osteoporotic vertebral compression fractures (VCFs). The TBS has attracted attention as a measurement of trabecular bone microarchitecture. It is derived from data obtained using dual-energy X-ray absorptiometry (DXA) and is a reported indicator of VCFs, and its addition to the Fracture Risk Assessment Tool increases the accuracy of fracture prediction. BMD, skeletal muscle mass, and TBS were measured in 142 patients who visited Shimoshizu National Hospital from April to August 2019. Patients were divided into a VCF group and a non-VCF group. Whole-body DXA scans were performed to analyze body composition, including appendicular skeletal muscle mass index (SMI; lean mass [kg]/height [m2]) and BMD. The diagnostic criteria for sarcopenia was an appendicular SMI <5.46 kg/m2. A logistic regression analysis was conducted to identify the risk factors for VCFs. The significant ( Patients with VCFs had low BMD, a low TBS, and low skeletal muscle mass. Lower femoral BMD and decreased leg muscle mass were identified as risk factors for VCFs independent of age, whereas the TBS was not identified as a risk factor for VCFs.

We report a successful case of fulminant myocarditis treated with central ECMO with a transapical left ventricular vent (TLVV). A 33-year-old man was diagnosed with fulminant myocarditis with acute biventricular failure. Using a cardio-pulmonary bypass, we introduced central ECMO with ascending aortic perfusion, right atrial venous drainage and TLVV. After ancillary circulation, his cardiac function gradually improved. The endotracheal tube was removed 5 days after the surgery (POD 5), and he was weaned from ECMO on POD 7 and discharged on POD 38. Although there are many cases in which peripheral veno-arterial ECMO (VA-ECMO) is used for fulminant myocarditis, there is a drawback to VA-ECMO : left ventricle (LV) unloading may be incomplete. Insufficient LV unloading may cause pulmonary congestion or disadvantage in myocardial recovery. TLVV can be used as a solution to unload the left ventricle. Central ECMO with TLVV should be useful therapy for fulminant myocarditis.

A 76-year-old man with a complaint of dyspnea was diagnosed with acute severe mitral regurgitation due to ruptured chordae tendineae. For improvement of pulmonary congestion, we introduced IMPELLA 5.0® and extra-corporeal membrane oxygenation before valve surgery. After two-days' IMPELLA 5.0® support, mitral valve replacement surgery with a bioprosthetic valve was performed and IMPELLA 5.0® was withdrawn. We report a successful case of a bridge to surgery using IMPELLA 5.0® with mitral valve regurgitation accompanied by acute left heart failure with severe respiratory failure.

STUDY DESIGN: Retrospective observational study. PURPOSE: We considered the relationship between spinal alignment and skeletal muscle mass on clinical outcomes following a surgery for lumbar spinal stenosis (LSS). OVERVIEW OF LITERATURE: There are no reports of preoperative factors predicting residual low back pain following surgery for LSS. METHODS: Our target population included 34 women (mean age, 74.4 years) who underwent surgery for LSS. Prior to and 6 months after the surgery, systemic bone mineral density and lean soft tissue mass were measured using dual-energy X-ray absorptiometry. Skeletal muscle mass index (SMI) was calculated as the sum of the arm and leg lean mass in kilograms divided by height in meters squared. The spinal alignment was also measured. Clinical outcomes were evaluated using the Japanese Orthopedic Association scoring system, leg and low back pain Visual Analog Scale, and Roland–Morris Disability Questionnaire (RDQ). Additionally, we examined the bone mineral density, skeletal muscle mass, and spinal alignment before and after the surgery. We used the Spearman correlation coefficient to examine the associations among clinical outcomes, preoperative muscle mass, and spinal alignment. RESULTS: Sarcopenia (SMI <5.46) was observed in nine subjects (26.5%). Compared with normal subjects (SMI >6.12), RDQ was significantly higher in subjects with sarcopenia (p=0.04). RDQ was significantly negatively correlated with SMI (r=−0.42, p<0.05). There was a significant positive correlation between postoperative RDQ and pelvic tilt (PT; r=0.41, p<0.05). SMI and PT were significantly negatively correlated (r=−0.39, r<0.05). CONCLUSIONS: Good postoperative outcomes were negatively correlated with low preoperative appendicular muscle mass, suggesting that postoperative outcomes were inferior in cases of decreased appendicular muscle mass (sarcopenia). Posterior PT due to decreased limb muscle mass may contribute to postoperative back pain, showing that preoperatively reduced limb muscle mass and posterior PT are predictive factors in the persistence of postoperative low back pain.

OBJECTIVE: It is important to develop an easy means of diagnosing lumbar foraminal stenosis (LFS) in a general practice setting. We investigated the use of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) to diagnose LFS in symptomatic patients. METHODS: Subjects included 13 cases (mean age, 72 years) with LFS, and 30 cases (mean age, 73 years) with lumbar spinal canal stenosis (LSCS) involving one intervertebral disc. The visual analogue scale score for low back pain and leg pain, the JOABPEQ were evaluated. RESULTS: Those with LFS had a significantly lower JOA score (p<0.001), while JOABPEQ scores (p<0.05) for lumbar dysfunction and social functioning impairment (p<0.01) were both significantly lower than the scores in LSCS. The following JOABPEQ questionnaire items (LFS vs. LSCS, p-value) for difficulties in: sleeping (53.8% vs. 16.6%, p<0.05), getting up from a chair (53.8% vs. 6.6%, p<0.001), turning over (76.9% vs. 40%, p<0.05), and putting on socks (76.9% vs. 26.6%, p<0.01) such as pain during rest, and signs of intermittent claudication more than 15 minutes (61.5% vs. 26.6%, p<0.05) were all significantly more common with LFS than LSCS. CONCLUSION: Results suggest that of the items in the JOABPEQ, if pain during rest or intermittent claudication is noted, LFS should be kept in mind as a cause during subsequent diagnosis and treatment. LFS may be easily diagnosed from LSCS using this established patient-based assessment method.

We report a case of endovascular surgery in a patient of common iliac artery aneurysm with arteriovenous (A-V) fistula. A 60-year-old woman was admitted because of dyspnea. She had a clinical history of lumbar disk surgery at age of 40. On physical examination, we detected a pulsatile mass and pansystolic murmurs in her left lower abdomen. A chest X-ray film demonstrated severe cardiomegaly with 70% of cardiothoracic ratio. Contrast-enhanced CT revealed left common artery aneurysm with A-V fistula between the left common iliac artery and the left common iliac vein. Three-dimensional CT showed hyper-vascularity in the region from the pelvic vein to IVC. We considered that she had high risk of intraoperative massive bleeding for open abdominal surgery. We conducted endovascular repair for this iliac artery aneurysm with A-V fistula by the GORE EXCLUDER C3® stent graft system. Postoperative contrast-enhanced CT showed complete exclusion of both left common iliac artery aneurysm and A-V fistula. After surgery, her symptoms improved significantly.

Diagnosis of lumbar foraminal stenosis remains difficult. Here, we report on a case in which bilateral lumbar foraminal stenosis was difficult to diagnose, and in which diffusion tensor imaging (DTI) was useful. The patient was a 52-year-old woman with low back pain and pain in both legs that was dominant on the right. Right lumbosacral nerve compression due to a massive uterine myoma was apparent, but the leg pain continued after a myomectomy was performed. No abnormalities were observed during nerve conduction studies. Computed tomography and magnetic resonance imaging indicated bilateral L5 lumbar foraminal stenosis. DTI imaging was done. The extraforaminal values were decreased and tractography was interrupted in the foraminal region. Bilateral L5 vertebral foraminal stenosis was treated by transforaminal lumbar interbody fusion and the pain in both legs disappeared. The case indicates the value of DTI for diagnosing vertebral foraminal stenosis.

STUDY DESIGN: Retrospective observational study. PURPOSE: To examine fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values of damaged nerves to discriminate between lumbar intraspinal stenosis (IS) and foraminal stenosis (FS) using diffusion tensor imaging (DTI) OVERVIEW OF LITERATURE: It is important in the selection of surgical procedure to discriminate between lumbar IS and FS, but such discrimination is difficult. METHODS: There were 9 cases of IS, 7 cases of FS, and 5 healthy controls. The regions of interest were established in the lumbar intraspinal zone (Iz), nerve root (N), and extraforaminal zone (Ez). The FA and ADC values were measured on the affected and unaffected sides of the nerves. The FA ratio and the ADC ratio were calculated as the affected side/unaffected side ×100 (%). RESULTS: In the Ez, the FA value was significantly lower in FS than in IS (p<0.01). FA ratio was significantly lower in FS than in IS for the Ez (p<0.01). In the Iz, the ADC value was significantly higher in IS than FS (p<0.01). ADC ratio was significantly higher in FS than in IS for the N and Ez (p<0.05). For the Ez, receiver operating characteristic analysis of parameters revealed that the FA values showed a higher accuracy for the diagnosis of FS than the ADC values, and the FA value cut-off value was 0.42 (sensitivity: 85.7%, false positive: 11.1%) and the FA ratio cut-off value was 83.9% (sensitivity: 85.7%, false positive: 22.2%). CONCLUSIONS: The low FA value in the extraforaminal zone suggests the presence of foraminal stenosis. When the FA value and FA ratio cut-off value were established as 0.42 and 83.9%, respectively, the accuracy was high for the diagnosis of foraminal stenosis. It may be possible to use DTI parameters to help in the discrimination between IS and FS.
