乳腺癌3例(占12.5%)，其中导管原位癌2例，浸润性导管癌1例；良性乳腺病变21例(占87.5%)，其中囊性小叶增生9例，乳腺导管增生及扩张6例，硬化乳腺病5例，导管内乳头状瘤1例。

Emblica have many different forms and most of them have tails and their perforation plates divide into two types:(1)there is one simple perforation plate at each end of the vessel elements and (2) there is one simple perforation plate at one end of the vessel elements and two simple perforation plate at the other end;(3)a few vessel elements have special inclusions;(4)the intervascular pits are alternate pits;(5)the pits between the vessels and rays are mixed pits ,pits with transverse gashes and scalariform pits.

结果发现，余甘子次生木质部导管分子中存在着许多不同的样式，导管分子大多数具尾；其穿孔板存在着两种类型：(1)两端均为1个单穿孔板；(2)一端为1个单穿孔板；另一端为2个单穿孔板；(3)极少数的导管分子具有特殊的内含物；(4)管间纹孔式为互列纹孔式；(5)导管射线间纹孔式为混合型纹孔与横列刻痕状纹孔以及梯状穿孔。

The causes were right auricle injury by violently placing a electric catheter to it (n=2),coronary sinusinjury by violently placing a electric catheter to distal CS (n=3) and by intracardiac electric defibrillation using electric catheter electrodes of high right atrium and CS as current loop(n=1),perforations of right atrial wall (n=3) and left atrial wall(n=2) by sliding up of the transseptal set,and perforation of left auricle by misplacing the mapping catheter of left superior pulmonary vein to it (n=1). 10 cases of acute tamponade occurred during operation, and 2 after operation.12 patients were treated successfully with urgent pericardiocentesis, and no patients required emergency surgery.

引起心包填塞的原因有：①放置电极导管至右心耳时用力过大致右心耳损伤(2例)；②放置电极导管至冠状静脉窦时，因导管不易进入远端而用力过大致CS损伤(3例)；③心内电除颤时采用高位右房和CS电极作回路，致CS损伤(1例)；④房间隔穿刺系统向上滑动穿破右房(3例)和左房(2例)；⑤放置左上肺静脉标测电极时导管误入左心耳致其穿孔(1例)。10例急性心包填塞出现于术中，另2例术后发生。12例患者经紧急心包穿刺引流均成功治愈，无1例需外科急诊手术。
