A 59-year-old woman with blunt multiple trauma was transferred to our emergency unit. A computed tomography revealed both an intimal flap of the descending aorta and cerebral bleeding. Immediate aortic surgery was considered, however full heparinized cardiopulmonary bypass (CPB) was not suitable because of acute brain hemorrhage. We performed surgery 55 days after the trauma. On operation 75% of the intima at the descending aorta was disrupted circumferentially. The descending aorta was replaced by a prosthetic graft under CPB. The postoperative course was uneventful and the patient has been well for 30 months after surgery. In treating aortic dissection associated with blunt trauma, emergency surgery should be performed immediately when possible, however there can be some limitations because of other acute organ injury. Accurate information concerning other injured organs, obtained by careful examination, may help an appropriate decision to be reached.

We encountered a patient with platypnea-orthodeoxia syndrome. This rare syndrome is characterized by right-to-left shunt, which appears in the upright position. A 76-year-old woman with symptomatic hypoxemia was referred for evaluation and treatment. She did not complain of dyspnea while in a supine position, but experienced dyspnea with severe hypoxemia in a sitting or standing position. She did not have any pulmonary diseases that can be cause of dyspnea. Echocardiography revealed a patent foramen ovale and mild left-to-right shunt when the patient was supine. However in an upright position, right-to-left shunt appeared and the arterial oxygen saturation dropped from 95% to 80% with dyspnea. Cardiac catheterization revealed normal pulmonary artery pressure and right-to-left shunt through the patent foramen ovale in the sitting position. We then diagnosed platypnea-orthodeoxia syndrome. The chest CT showed deformity of the right atrium caused by compression of the elongated ascending aorta. The patent foramen ovale was closed and the ascending aorta was shortened by open heart surgery. Her dyspnea and hypoxemia in the upright position was completely resolved after surgery.

We report successful operative treatment of a ruptured coronary artery saccular aneurysm associated with a coronary-pulmonary artery fistula. A 66-year-old woman experienced sudden onset of unconsciousness due to cardiac tamponade. Echocardiogram and chest CT on admission showed pericardial effusion and a 50-mm diameter saccular coronary artery aneurysm. Coronary angiogram revealed coronary artery aneurysm which arose on the conus branch of the right coronary artery. The connection between the aneurysm and the pulmonary artery was not clarified. Cardiac tamponade due to rupture of the saccular coronary artery aneurysm was suspected and emergency operation was performed. Operative findings revealed coronary-pulmonary artery fistula. Closure of the orifice of the draining artery to the pulmonary artery, and aneurysmorrhaphy were performed. Postoperative coronary angiogram and chest CT showed no residual fistula, and the postoperative course was uneventful.

We applied electrical acupuncture to the spinal nerve root by inserting needles under x-ray control in two cases with radicular sciatica as a non-pharmacological substitute for the lumbar spinal nerve block. In both cases, symptoms were markedly reduced after electrical acupuncture to the spinal nerve root. The sustained effect was noticeably longer than that of caudal anesthesia previously performed one time on one of the cases. We suggest that descending inhibitory control, inhibitory control at the spinal level, or changes in nerve blood flow may be involved in the mechanism of the effect of electrical acupuncture to the spinal nerve root. These results suggest that electrical acupuncture to the spinal nerve root may be superior to lumbar spinal nerve block or caudal anesthesia when it is applied appropriately in certain cases of radicular sciatica, taking into consideration of patient age, severity of symptoms and duration of the disorder.

Objective: Snapping finger is the result of gliding disorder of the superficial and deep digital flexor tendon and the flexor pollicis longus muscle tendon at the synovial and ligamentous tendon sheath (A1 pulley). In this study, acupuncture was performed at the A1 pulley of the affected finger to determine its effect on pain during snapping and the degree of the snapping phenomenon. Methods: Acupuncture was performed on 19 fingers of 15 patients. No control group of untreated patients was included in the study, and the same acupuncture treatment was used for all of the patients. The acupuncture needles were inserted in the radial and ulnar sides of the flexor tendon (left inserted for 10 min) at the A1 pulley of the affected finger. Treatment was performed a maximum of 5 times (once every 5 to 7 days). Before and after each treatment, the pain during snapping and the degree of the snapping phenomenon were evaluated using a visual analogue scale (VAS) ranging from 0 mm (no symptoms) to 100 mm (intolerable symptoms). Symptoms before the first treatment and before the fifth treatment were compared to determine the degree of change, taking a 50% improvement as the criterion for judging whether there was an improvement or not, and the relationship between improvement or lack of improvement and the duration of the disorder was examined. Results: VAS evaluation showed a significant improvement in pain during snapping and the degree of the snapping phenomenon with scores before the first treatment and before the fifth treatment of 57.1±22.2 (mm, mean±SD)→26.0±29.8, 61.2±23.1→26.1±27.6 respectively. VAS evaluation directly after the first treatment also showed a significant improvement in pain and the degree of the snapping phenomenon with scores of 40.8±19.6 and 44.3±23.9 respectively. Furthermore, by the fifth treatment, pain and the snapping phenomenon were observed to have completely disappeared in 4 and 6 fingers respectively. In patients showing an improvement in pain and the snapping phenomenon, the duration of the disorder was significantly short. Discussion: It is unlikely that acupuncture had an influence on the degeneration and thickening of the ligament tendon sheath. Improvement in the snapping phenomenon is thought to be the result of acupuncture treatment changing regional blood flow and thereby exerting a favorable influence on inflammatory swelling. The alleviation of pain during snapping is believed to be the result of improved flexor tendon gliding as well as the involvement of acupuncture in activation of the pain inhibitory system. Since no control group of untreated patients or sham treatment group were included in the study, the possibility of a placebo effect influencing the results cannot be completely excluded. However, because a difference was observed in the efficacy of the treatment depending on the duration of the disorder, the view is that acupuncture at the impaired A1 pulley could be effective treatment for snapping finger when the main cause is inflammatory swelling of the synovial membrane of the tendon sheath and when the duration of the disorder is short.
