Objective To observe the morphological changes of brain and to analyze the cause of coma after open-heart surgery in cases suffered from congenital heart disease. Methods Twenty six autopsy cases were collected from Jan. 1973 to Sep. 1999 in Fuwai Hospital. Their duration of coma was 1 day to 40 days and all of them died earlier later following cardiac surgery. Their surgical procedure, extracorporeal circulation time, and other clinical records and autopsy findings were reviewed. Results The brain lesions included intracranial hemorrhages (n=11), cerebral edema (n=11), encephalitis and encephalomingitis (n=3), and cerebromalacia (n=1). Intracranial hemorrhages occurred in epidural (n=3), subdural (n=3), subarachoid spaces (n=4), and intracerebral parenchyma (n=1). The causes of coma were deduced as follows: lower cardiac output (n=7), air embolism (n=3), pneumonia (n=3) and other infections (n=2), pulmonary hypertension (n=2), and the unknown causes of coma (n=9). But the 6 out of the last 9 cases showed longer duration (more than 100 min) of extracorporeal circulation. Intracranial hemorrhages occurred more frequently in cases with waking period than those without after cardiac operation, and vice versa the cerebral edema. Conclusion Intracranial hemorrhage and cerebral edema were the main changes of brain in the patients suffered from coma, but its causes were complex and difficult to analyze. These results suggest that further improved heart preservation, shorter time of extracorporeal circulation and effective treatment of infection would be benefit to the prevention of coma.

Objective To compare the image quality and radiation dose between prospective ECG-trigering and retrospective ECG gating technique in coronary artery imaging. Methods 33 patients suspected coronary artery disease were included in this study and divided into experimental group (prospective ECG-triggering coronary artery imaging, heart rate < 65 bpm, 16 patients)and control group (retrospective ECG gating coronary artery imaging, heart rate < 75 bpm, 17 patients). Radiation dose was recorded for statistical analysis. At the same time, image quality was evaluated. Results There were no significant differences in image quality 3.2 msy. Effective dose reduced 76.47 %. Conclusions Prospective ECG gating coronary artery imaging can obtain the similar image quality compared with prospective ECG gating coronary artery imaging but the effective dose reduced 76.47 %. Prospective ECG gating coronary artery imaging has clinical value to peoples who are able to not accept high radiation dose and with low heart rate.

Objective To analyze the surgical and pathologic features of isolated ascending aortitis without evidence of rheumatologic or autoimmune diseases by comparing that of Takayasu's arteritis.Methods Consecutive 965 excised ascending aortas were reviewed and 40 cases with aortitis were selected from the pathological archives of past 20 years in Fuwai Hospital.The clinical history,laboratory and angiographic data,surgical findings,steroid therapy and followup results of these 40 cases were reviewed.Pathological parameters included the thickness of aortic wall and its various layers,inflammation activity,multinuclear giant cells,inflammatory necrosis,laminar necrosis and atheroselerosis.The t test and Chi square analysis were used to compare the means and the rates between the two groups.Results Twenty-five of 40 cases were diagnosed with isolated aortitis and its prevalencei was 2.6%(25/965),while 8 cases with Takayasu's arteritis and 7 cases with other vasculitis were confirmed.The age of isolated ascending aortitis was older than that of Takayasu's arteritis[(46±12)y vs(34±14)y,t=2.30,P>0.05] while the male/female ratio was similar in both groups(1.1 vs 1.0,t=0.01,P>0.05).Their main clinical manifestation was aortic aneurysm with a bigger aortic diameter in isolated aortitis than that in Takayasu's arteritis [(59±18)vs(46±12)mm,P>0.05].The asymptomatic cages mostly were found in isolated ascending aortitis (28%vs 0,x2=2.98,P>0.05).The erythrocyte sedimentary rate was normal in isolated aortitis but increased in Takayasu's arteritis[(15±17)mm/1 hvs[27±25)mm/1 h,U=48.50,P<0.05 ].Inflammatory edema,thickening and calcification were noted in more than half cases of both groups.but slighter thickening of aortic wall was foand in isolated ascending aortitis in contrast to the remarkable thickening in Takayasu artefifis[(2506±493)vs (3300±430)μm,t=-3.00,P<0.01].Giant cells,inflammatory necrosis,laminar necrosis and accompanied atherosclerosis were more common in isolated ascending aortitis.Aortic regurgitation was common but inflammatory invasion wege found in few aortic valves. Steroid was prescribed in 5 cases with isolated ascending aortitis and none of them was reported with complications while aortic perivalvular leakage occurred in 3 of 20 cases without steroids therapy. In the Takayasu's arteritis cases, new aneurysm of abdominal aorta was found in 1 of 3 cases with steroid therapy. Meanwhile, perivalvular leakage and subclavian artery stenosis occurred in 2 of 5 cases without steroid. Conclusion Isolated aortitis is more common than Takayasu's arteritis in ascending aortic diseases and there is some definite difference in clinical and pathological aspects between these two diseases. Since the effect of steroid therapy is uncertain and in order to avoid overtreatment, we suggest that steroid should not be given to cases with isolated ascending aortitis after surgery and clinical and angiographic follow-up should be emphasized.

Objective To evaluate large field diffusion-weighted imaging (DWI) in detection of bone metastases of malignant tumors. Methods Eighteen patients with various malignant tumors were enrolled in this study. All the patients underwent large field DWI and 99mTc-MDP bone scintigraphy within one month. Results Fifteen of 18 patients were diagnosed as bone metastases with conventional MRI; 7 of them were found more than 10 bone metastases, and 23 bone metastases were confirmed in the other 8 patients. When seven patients with multiple bone metastases (>10) were excluded, and lesions in the residual 11 patients with or without bone metastases were counted, the diagnostic sensitivity of bone metastases with large field DWI and bone scintigraphy was both 100%, and specificity were 100% and 33.33%, respectively. ROC study showed the area under curve (AUC) of large field DWI and bone scintigraphy were 1.00 and 0.67, respectively (P=0.04). With lesion numbers as study unit, the diagnostic sensitivity of large field DWI and bone scintigraphy were 86.96% and 78.26%, and the specificity was both 60.00%. ROC study showed the AUC of large field DWI and bone scintigraphy was 0.74, 0.69, respectively; and no statistical difference was found. Conclusion Large field DWI can be used in screening the bone metastases of malignant tumors.
