A variety of clinical variables and physiological parameters have been discussed in relation to postoperative survival and symptoms in aortic regurgitation (AR). Many of them have been derived from left ventricular morphology and functions, but there has been no parameter from aortic functions. As the heart is united with the aortic tree to form a circulatory system and both heart and aorta affect each other, aortic functions also have an important prognostic value after aortic valve replacement (AVR). This study was performed to clarify the participation of aortic functions in determining the prognosis after AVR. Fifteen consecutive patients undergoing isolated AVR for AR were evaluated. Twenty-one preoperative hemodynamic and dimensional variables of both heart and aorta were analyzed to determine the risk factors for early postoperative morbidity. These variables were obtained from chest X-ray film, electrocardiogram, echocardiogram, cine-aorto-ventriculogram and pressure manometries. All patients were divided in two groups according to the postoperative course. Group I composed of 10 patients took relatively smooth postoperative course, except two patients suffering from cardiac tamponade. Group II composed of 5 patients suffered from low cardiac output syndrome (LOS) and/or dangerous arrhythmias postoperatively. Two out of them died of uncontrollable ventricular arrhythmias. There were no statistic differences between two groups in the factors derived from preoperative examinations, i.e. CTR, LVDsI, PWT, R/Th, %FS, EDVI, EF, CI, LVEDP, etc. Mean aortic compliance of group II, (3.8 +/- 2.1) X 10(-4) mmHg-1, was, however, significantly lower than that of group I, (21.7 +/- 4.8) X 10(-4) mmHg-1, (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Sonographically guided core-needle biopsy of focal splenic lesions: report of four cases 总被引:1,自引:0,他引:1

There are few published reports about the use of splenic needle biopsies in the investigation of focal splenic lesions. We report our experience with sonographically guided core-needle biopsies of splenic lesions in 4 patients. The biopsies resulted in the following diagnoses: sarcoidosis, malignant lymphoma, infarction, and scar tissue. Surgery was avoided in the 3 patients diagnosed with sarcoidosis, infarction, and scar tissue by ruling out the possibility of a malignant splenic tumor. None of the patients experienced significant complications. We conclude that splenic core-needle biopsy is a useful and safe diagnostic tool for the evaluation of focal splenic lesions. 相似文献

Background
It is known that complex regional pain syndrome (CRPS) occurs after arthroscopic rotator cuff repair (ARCR); however, few studies have investigated this complication. Therefore, the purpose of the present study was to evaluate CRPS after ARCR.Methods
A total of 182 patients who underwent ARCR were enrolled in this study. The average age of patients was 62.8 ± 10.0 years, with an average follow-up period of 21.5 ± 38.1 months. CRPS criteria outlined by the Ministry of Health, Labor, and Welfare study team for CRPS in Japan (MHLWJ) and International Association for the Study of Pain (IASP 2005) were utilized for diagnosis. There are two rating systems for the “clinical purpose” and “research purpose” in both criteria, respectively. Clinical outcomes, including Japanese Orthopedic Association (JOA) and University of California, Los Angeles scores, were evaluated using univariate and multivariate analysis.Results
CRPS exclusively occurred in the hand of the operated limb, developing within 3 months of surgery. Two or more of the following symptoms were noted in patients with the hand lesion associated with CRPS: edema (93.4%), restricted range of motion (83.4%), hyperalgesia (30.1%), paridrosis (20.4%), and atrophic change (12.2%). Under these conditions, the incidences of CRPS were 24.2% (44/182) when evaluated by the MHLWJ rating system for the “clinical purpose;” 11% (22/182) by the MHLWJ rating system for the “research purpose;” 6% (11/182) by the IASP 2005 for the “clinical purpose;” and 0.5% (1/182) by the IASP 2005 for the “research purpose.” Results of multivariate analysis demonstrated that “Function” in the JOA score was a risk factor for the development of CRPS after ARCR, when evaluated by a system for the “clinical purpose” of the MHLWJ.Conclusion
Following ARCR, CRPS-induced hand lesions occur more frequently than is generally believed, thereby suggesting that its impact on surgical outcomes should be clarified in the future. 相似文献104.

Percutaneous microwave coagulation therapy for superficial hepatocellular carcinoma on the surface of the liver 总被引:1,自引:0,他引:1

BACKGROUND/AIMS: This study was performed to evaluate the efficacy and safety of percutaneous microwave coagulation therapy for superficial hepatocellular carcinoma located on the surface of the liver. METHODOLOGY: Among 58 cirrhosis patients with 71 hepatocellular carcinomas measuring < or = 20 mm in greatest dimension, 18 patients had a solitary superficial lesion located on the liver surface (superficial hepatocellular carcinoma group) and the other 40 patients had 53 lesions that were not in contact with the liver surface (non-superficial hepatocellular carcinoma group). All patients were treated by percutaneous microwave coagulation therapy alone and the response was assessed by using contrast-enhanced CT. The survival, tumor recurrence, and adverse effects were compared between the superficial and non-superficial hepatocellular carcinoma groups. RESULTS: The 4-year survival rates of the superficial hepatocellular carcinoma group (64.2%) and the non-superficial hepatocellular carcinoma group (58.9%) were not significantly different, and neither were the 4-year local recurrence rates (27.1% vs. 29.8%). Although there was a significantly higher incidence of severe pain during microwave irradiation in the superficial hepatocellular carcinoma group (23/47) when compared with the non-superficial hepatocellular carcinoma group (25/148), there were no differences between them in the incidence of fever or the changes in liver function after treatment. There were no serious adverse effects, such as hemorrhage or tumor cell seeding, in either group. CONCLUSIONS: Percutaneous microwave coagulation therapy can be performed safely, even in patients with superficial hepatocellular carcinoma and cirrhosis, so this method is effective for treating hepatic neoplasms regardless of the tumor location. 相似文献

We treated two patients with atrial fibrillation and stringlike left atrial appendage thrombus: a 66 year-old man who had
apical hypertrophic cardiomyopathy and a 86 year-old woman with no underlying heart disease. In the patient with hypertrophic
cardiomyopathy, transesophageal echocardiography showed a highly mobile stringlike echo protruding from the left atrial appendage
and sometimes falling into the mitral orifice. Pathologic examination after excision proved the stringlike echo to be a pedunculated
structure composed of red and white thrombi. Excision of thrombus was also planned for the woman, who had a history of recurrent
cerebral embolism. Because her cerebral CT showed infarction with bleeding, however, surgery was postponed. The stringlike
mobile thrombus was not detected by transesophageal echocardiography 1 month later, when a new embolic episode affected a
foot. Clinical outcomes of these two patients differed remarkably. The critical findings by transesophageal echocardiography
which facilitated differential diagnosis from cardiac tumors were: spontaneous contrast echo accompanying mural thrombuslike
echo, and low flow velocity in the left atrial appendage. However, the differential diagnosis may be quite difficult in cases
of tumors associated with atrial fibrillation. 相似文献

BACKGROUND: The toxicity of dietary nitrate (NO3-) is controversial. One reason is nitrate metabolism in the intestine is so complicated that it is far from fully understood. There is no study measuring breath nitric oxide (NO) and nitrous oxide (N2O) after ingesting vegetables and high-nitrate food at the same time. METHODS: Breath samples from 10 healthy young and 10 healthy old subjects were collected at 15-min intervals for 5 h after ingestion of 100 g of lettuce and during fasting (control). Breath NO and N2O were analyzed by a chemiluminescence and an IR-PAS analyzer respectively. RESULTS: N2O maximum concentration and excretions increased significantly after ingesting lettuce in each group [303 (30) vs. 750 (81) ppb, 771 (72) vs. 1668 (146) microg in young; 442 (52) vs. 1092 (109) ppb, 1088 (125) vs. 2100 (183) microg in old subjects; mean (SE), P<0.01], while NO did not. In addition, breath NO was strongly influenced by ambient NO, which varied greatly. N2O maximum level in old subjects after ingesting lettuce was higher than that of young subjects (750 vs. 1092 ppb, P<0.05), and significantly higher N2O concentration levels were seen at 30, 45, 60, and 105 min in old subjects. CONCLUSIONS: A large amount of N2O produced in the intestine and normal nitrate intake do not influence the breath NO concentration, probably due to its relatively small production. Higher maximum N2O concentration after ingesting lettuce in old subject is probably because more bacteria, which rapidly reduce dietary nitrate in the upper intestinal tract, inhabit the gut in old age. Our results suggested that breath N2O is a useful noninvasive maker to estimate dietary nitrate reduction in the intestinal tract. 相似文献

We have developed an iso-integral mapping technique that uses magneto-cardiogram (MCG) data to obtain a map as projected total current image on the torso from the heart. We have also investigated the applicability of iso-integral mapping to the diagnosis of ischemic heart disease. We simulated and measured the characteristics of two types of iso-integral maps: one using tangential (B xy ) components, and one using the normal component (B z ). Each vector component was measured by two types of superconducting quantum interference device (SQUID) system to determine the tangential and normal components. The tangential component of the magnetic field appeared to be equivalent to the current image in the myocardium projected on the observing plane, and we were able to obtain a projected total current image by integration of the tangential components during the depolarization and repolarization processes. And we found that the iso-integral maps of normal hearts showed similar pattern in both processes; however, those of ischemic hearts showed different patterns. 相似文献
