A Study Of The Image Anatomy In The Ramicentrales Of Middle Cerebral Artery

Objective:A research of MCA central branch’s initiation, contorts,fragmentation and its diameter; Statistical measurements to study theissue through the characteristics and related anatomic data. The purposeis to better understand the central branch of the middle cerebral artery’sanatomy structure, provide clinical phenomenon of frequent occurrenceof middle cerebral artery aneurysm anatomy, and the security of thelateral fissure approach for treating brain diseases to provide theanatomical data.Materials and methods:Built between January2006and January2013, Bethune medicalcollege Jilin university first hospital patients of the brain artery MRAimages, selection criteria are:1) children aged less than15;2) no seriousheart disease affects the brain normal blood supply, large vascular disease;3) no cerebral venous lesions, and affects the brain venous reflux disease,4) have been excluded from cerebrovascular malformation, stenosis andaneurysm. Using GE DiscoveryTMMR7503.0T magnetic resonanceimaging machine to scan head of subjects, the image on to AW VolumeShare after4AW4.5workstations before processing to observe.The results:1.Backbone is a continuation of the internal carotid arteries in thebrain, ending the most in the island before it is bifurcation threshold, it is12.3±2.1mm, the length of the pipe diameter is11.9±2.8mm2.Middle cerebral artery perforators of the medial group number is on the left side of the5.1±2.1mm, the right side.8±2.4, the lateralgroup of perforators number is on the left side of the4.68±2.1,5.1±2.41mm on the right side.3.MCA central branch of the medial group of perforators pipediameter to the left of1.0±0.4mm,1.8±0.4mm, the right side ofthe middle cerebral artery central branch of the lateral group ofperforators of the pipe diameter is on the left side of the1.2±0.4mm,0.1±0.3mm, right4.The trunk of the middle cerebral artery is often a not a branch, thelength of the segment for5.Middle cerebral artery in island threshold will continue contortsissued a multilevel branching mostly, common middle cerebral arterybranch has, one branch, double branches and multiply branches. Thisexperimental results show that the one branch accounted for about25%,double branches accounted for about50%, multiply branches accountedfor about25%more.Conclusion:1. In the trunk of middle cerebral artery and contorts the circuity, aswell as the special branch way is one of the multiple causes of brainaneurysms.2. The central branch of the middle cerebral artery in perpendicularto the artery branch, the cause of the cerebral hemorrhage happens here.3. The horizontal section at the end of the middle cerebral arterybifurcation is a good location, middle cerebral artery aneurysms andaneurysms in GaBi here should particularly pay attention to protect thesurrounding MCA central branch and cortical branches..
