对角支

对角支向侧方走行，主要供应LV游离壁。

The diagonal branches course laterally and predominantly supply the LV free wall .

切割球囊经皮腔内冠状动脉血管成形术治疗对角支开口病变47例

Cutting balloon coronary angioplasty treats 47 patients with diagonal branches ostial lesion

LAD的主要分支有对角支和室间隔支。

The major branches of the LAD artery are the diagonal and septal perforating arteries .

方法25～3kg家兔16只，随机分为2组，对照组（control）：单纯结扎冠状动脉左对角支；

Methods Sixteen rabbits ( 2.5 ~ 3 kg ) were randomly divided into two groups , control group : only left coronary artery was occluded ;

结果：①前间隔AMI患者前降支闭塞位置大都发生在第1间隔支和第1对角支开口远端，且单支病变多见。

Results : ① The location of the LAD coronary artery occlusion occured at distal to the origin of the first septal breach ( S1 ) and the first diagonal branch ( D1 ) in the most of the patients with anteroseptal AMI .

选民转而支持左派.分离左冠状动脉左前降支，第二对角支远端结扎。

Voters have / Voting has swung to the left . Left descending arteries were ligated at the distal side of the second diagonal branch .

分叉病变部位：前降支和对角支处分叉病变29例，回旋支和钝缘支处分叉病变16例，左心室后侧支与后降支处分叉病变8例。

29 bifurcation lesions were related to left anterior descending artery and diagonal branch artery . 16 bifurcation lesions were in left circumflex and obtuse marginal branch position .

其中前降支占40%，对角支和钝缘支分别占27%和22.3%，回旋支为6.7%，右冠（后降支）5.0%。

The location in left anterior descending artery was 40 % , diagonal artery 27 % , left obtuse marginal branch 22.3 % , left circumflex artery 6.7 % , right coronary artery 5 % .

分叉病变的类型为前降支/对角支62例（54.9%），左冠状动脉主干分叉病变32例（28.3%），回旋支/钝缘支18例（15.9%），右冠状动脉远端分叉病变1例。

Sixty-two of the bifurcation lesions were located in LAD / diagonal ( 54.9 % ), 32 in distal left main coronary arteries ( 28.3 % ), 18 in LCX / OM ( 15.9 % ) and 1 distal RCA ( 0.9 % ) .
