Objective To investigate the prevalence of morphological abnormalities of the internal carotid artery and relationship with ischemic cerebrovascular disease and carotid atherosclerosis.Methods A total of 511 consecutive patients were enrolled in this study and carotid abnormalities were classified according to the criteria of Wain and Metz by combining high-and low-frequency ultraaonography prospectively.Relationship of carotid abnormalities to ischemic cerebrovascular disease and carotid atherosclerosis were analyzed.Results Of the 511 cases,abnormalities of the internal carotid artery were found in 256(50.1 ％),the unilateral carotid abnormalities were found in 121(23.7％),and the bilateral in 135(26.4％),respectively.There was significantly difference in prevalence of kinking and coiling between ischemic stroke and asymptomatic group(P＜0.001),and prevalence of carotid abnormalities in the plaques and arteriosclerosis groups were statistically higher than the normal group(P＜0.001).Conclusions The kinking and coiling of the internal carotid artery could be additive risk factors in the pathophysiology of an ischemic stroke,and carotid morphological abnormalities could be responsible for carotid atherosclerosis partly.

Objective To evaluate the diagnostic value of the ultrasonography in greater omentum lesions.Methods The ultrasonic findings in 33 patients with greater omentum lesions were compared with the pat hological result of operation,celioscope or ascites cytology.Results The lesions in 27 of 33 patients(81.8%)were localed within the treater omemurn,and pathological changes of 26/33(78.8%)were found by ultrasonography.These greater omentum lesions appeared as characteristics of thickened,shifted and peculiar-echo.Conclusion The lOcation and pathological nature of the primary affection can be approximately estinlated according to the localizatiOn and sonographic appearance of the greater omentum by experienced physicians.

Objective To evaluate clinical value of ultrasonography before and after stent implantation in the patients with obstructive jaundice.Methods Ultrasonic findings before and after stent implantation in 38 patients with obstructive jaundice were analyzed respectively,and location and pathological natures of the obstruction were compared with those of stent implantation.Results Stent implantation was successfully achieved in all the cases with hilum (15/15,100%) and common bile ducts obstruction(12/12,100%),ampulla of Vater (5/6,83%) ,and duodenal nipple(1/5,20%).A success rate of stent implantation was 100%(8/8) in benign lesions,and 83.3% (25/30) in malignant ones.The total success rate was 86.8%.The significant difference was found between the obstruction location and success rate of stent implantation ( P 0.05 ).Conclusions Ultrasonography not only contributes to diagnosis of location and pathological nature of the obstruction for successful stent implantation but also explores complications early.

Objective To investigate color Doppler flow imaging features of the ophthalmic artery,external carotid artery,which is known the secondary compensatory collateral circle,in patients with unilateral internal carotid artery occlusion.Methods A total of 42 patients with unilateral internal carotid artery occlusion were enrolled,and ipsilateral and contralateral ophthalmic artery,external carotid artery were examined by color Doppler flow imaging,prospectively,peak systolic velocity,pulsatility index and resistance index were analyzed and compared with findings of control group.Results In the 42 cases with internal carotid artery occlusion,the compensatory collateral circle was observed by the external carotid artery and ophthalmic branches,through their communicating arteries in 40 (95.2％) cases of chronic occlusion.Compared with the contralateral side,the ophthalmic arteries were characterized by retrograde blood flow,peak backward shifting,increase of diameter [(1.91 ± 0.53) mm vs (1.69 ± 0.34) mm,P =0.009] and peak systolic velocity [(43.41 ± 27.28) cm/s vs (29.91 ± 14.16) cm/s,P =0.003],reduced pulsatility index (1.18 ± 0.49 vs 1.69 ± 0.73,P =0.000) and resistance index (0.65 ± 0.26 vs 0.75 ±0.12,P =0.000),and prolonged acceleration time [(147.71 ± 56.16)ms vs (51.80 ± 7.81)ms,P =0.000].Ophthalmic arteries had antegrade blood flow with a decrease of peak systolic velocity and resistance in another two cases of acute thrombosis of ICA.Conclusions External-ophthalmic-internal carotid artery passway is another compensatory collateral circle for the chronic occlusion,but only by ipsilateral and contralateral internal carotid artery circle,for acute thrombosis.

Objective:To investigate the current use situation of hemostatics in preventing re-bleeding in the patients with sub-arachnoid hemorrhage. Methods:The records of patients with subarachnoid hemorrhage were selected from a hospital in 2016 and the types,dosage,course and drug adverse reactions of hemostatics were recorded and evaluated according to the drug information leaflets/related guideline,drug utilization researches and adverse drug actions monitoring. Results:Totally 81 cases with hemostatics involved 3 varieties of hemostatic drugs,the combination proportion was 16.05%,the reasonable use rate was 86.42%,the reasonable rate of administration route was 100%,the reasonable solvent rate was 98.77% and the course no more than 72 h was 88.89%. The drug uti-lization index of etamsylate injection and tranexamic acid injection was greater than one,indicating that the dosage was unreasonable. There were no adverse reactions in the 81 cases.Conclusion:The use of hemostatics in the patients with subarachnoid hemorrhage is common,and there is still unreasonable use (such as dosage and course etc) that we should pay attention to.
