狭窄

Cervical spondylosis is due to cervical back muscle strain as well as the unbalanced paravertebral muscle strength caused by long-term working with head drop, which thereby leads to a set of syndrome: cervical intervertebral disc degeneration, narrow intervertebral space, unstable vertebrae unit, protruded or extruded nucleus pulpous; hyperosteogeny, ligament pachynsis, narrow neural canal or nerve root canal; oppressed nerve root and spinal cord, stimulated vertebral artery and sympathetic nerve; aching and discomfort cervix; numbness and disability of the body; functional disorder in relieving the bowels; dizziness and nausea, etc.

Methods: In this series,coronary heart disease was proven by clinic,electrocardiogram and selective coronary arteriography.Causes of 30 cases of PICAS were acute coronary occlusion in PTCA (2 cases),coronary arterial dissection (1 cases),preventing coronary arterial restenosis after PTCA (18 cases),coronary arterial restenosis after PTCA (4 cases) and acute myocardial infarction (5 cases).Thirty cases of SCAG were performed by Judkins method.

材料和方法：本组病例均经临床，心电图和选择性冠状动脉造影证实为冠心病。30例经皮冠状动脉内支架植入术的原因有经皮腔内冠状动脉成形术中发生急性冠状动脉闭塞2例，冠状动脉夹层1例，为防止PTCA术后再狭窄18例，PTCA术后再狭窄4例，急性心肌梗塞5例。30例SCAG均采用Judkins法。

S.From all the patients with MB-MCA and whose MCA were encased by the myocardium completely,30 patients were choosed randomly,their datasets were reconstructed seriatim by every 5%R-R interval,the whole cardiac cycle were reconstructed by 20 phases,the diameter of the mural coronary arteries of every phase was reviewed and measured,the phases were found out where the diameters were maximal and minimal,the systolic compression rate was calculated,Pearson correlation analysis was used to analyze the relation between length,depth,and degree of systolic compression of the mural coronary artery.
