ABSTRACT
[Abstract] Objective To track and make statistics of the right pulmonary arteries’ branches and to study the clinical significance. Methods Technologies of vascular volume rending were used to analyze the 350 CT pulmonary angiography images. And the three-dimensional display was used to classify the pulmonary arteries. Results According to the 350 reconstructed result, the right upper pulmonary arteries were divided into 6 types: anterior trunk+ post ascending artery, anterior trunk, anterior trunk+ anterior ascending artery+ post ascending artery, superior anterior trunk + inferior anterior trunk+ post ascending artery, anterior trunk+ anterior ascending artery and superior anterior trunk+ inferior anterior trunk. The right middle pulmonary arteries were divided into 2 types: one branch and two branches. As for the right lower pulmonary arteries, the apical arteries were divided into 3 types: one branch, two branches and three branches. The basal segmental arteries were divided into 3 types: medial basal segmentalartery+anterior basal segmental artery+lateroposterior basal segmental artery, medioanterior basal segmental artery+lateroposterior basal segmental artery and medial basal segmental artery+anterior and lateral basal segmental artery +posterior basal segmental artery. To be specific, anterior trunk+ post ascending artery type (56. 6%) occupied the most in the right upper pulmonary arteries. The majority type of right middle pulmonary artery was one branch(57. 4%). In the right lower pulmonary arteries, apical artery of the lower lobe (one branch)+medial basal segmental artery+anterior basal segmental artery+lateroposterior basal segmental artery type(32. 5%) was most common. Conclusion The classification of the right pulmonary arteries based on the three dimensional reconstruction of CT pulmonary angiography is of significant to surgical precision therapy of lung tumor.
ABSTRACT
@#Objective To investigate the effect of early rehabilitation on neurological function and cerebral blood flow of patients with acute cerebral infarction.Methods100 cases of acute cerebral infarction were randomly divided into the rehabilitation group(53 cases) and control group(47 cases).Both groups received the routine treatment;besides,patients in the rehabilitation group were treated with early rehabilitation training.The treatment efficacy was assessed by neurological function deficit evaluation,and the cerebral blood flow was measured by transcranial Doppler(TCD) before and 30 days after treatment.ResultsThe scores of neurological function deficit evaluation of all patients in each group decreased after treatment,but the scores of the rehabilitation group were obviously lower than that of the control group(P<0.01);and the results of TCD of the rehabilitation group were also superior to that of the control group(P<0.01).ConclusionEarly rehabilitation training may obviously improve neurological function and cerebral blood flow of patients with acute cerebral infarction.
