赘生物

Macroscopic and microscopic assessments were done on the explanted devices. RESULTS: Macroscopic examination showed no excrescence, thrombus formation, arm fractures and corrosion.

结果：肉眼观：所有装置表面均没有发现赘生物、血栓形成、支架断裂及被腐蚀，术后3月装置大部分已被组织包埋，术后6月完全被包埋。

ResultsMacroscopic examination showed no excrescence,thrombus formation,arm fractures and corrosion.The devices were covered with collagen fibrosis and discrete endocardial cells,apparent inflammatory infiltration in the devices and around the devices 1 month after implantation.The implants were nearly endothelialized,while the inflammatory reaction relieved gradually,with myocardial cells ingrowth at the edges of the device 3 months after implantation.The devices were completely covered with endocardium and fibrous tissue.Moreover,endothelial cells could be found on the smooth microscrew adaptor.The inflammatory reaction diminished with a few chronic inflammatory cells existing.Neovascularization and lymphatic vessels ingrowth could be observed 6 months after implantation.

结果所有封堵装置表面均没有发现赘生物、血栓形成、支架发生断裂及被腐蚀；术后1个月，封堵装置表面被胶原纤维和散在内皮细胞所覆盖，大量炎症细胞浸润，封堵装置边缘有小灶性炎症细胞浸润；术后3个月，封堵装置表面几乎被内皮细胞所覆盖，炎症细胞较1个月时明显减少，封堵装置内见纤维化，封堵装置边缘心肌细胞浸入；术后6个月，封堵装置表面完全被心内膜和纤维组织所覆盖，伞尖表面光滑并有内皮细胞上爬，炎症反应明显消散，但仍有少量慢性炎症细胞存在，装置内有新生的血管、淋巴管长入。

It appears pink because it is composed of fibrin and platelets.

此赘生物呈现红色，是由纤维素和血小板构成的。

The friability explains how portions of the vegetation can break off and embolize.

赘生物的质地较脆，可以脱落，随着血流的运行引起栓塞。

The knobby excrescences at the left side of this vertebral column are due to degenerative osteoarthritis.

左边脊柱多节的赘生物是由退变性骨关节炎引起的。

Irregular reddish tan vegetations overlie valve cusps that are being destroyed.

不规则的红棕色疣状赘生物覆盖在主动脉的表面，而引起主动脉瓣膜被损伤。

Compared with nonembolism, IE patients with embolism are more likely to develop fever (92.1%), positive blood cultivation (76.3%), pseudomonas aeruginous infection (10.5%), larger neoplasm, higher white blood cell count, and poorer prognosis.

与对照组比较，栓塞组发热常见(92.1%)、血培养阳性率高(76.3%)、绿脓杆菌感染相对多见(10.5%)、赘生物直径较长及预后差。

However, they are very prone to embolize.

但是，此赘生物易脱落，形成栓塞。

These vegetations appear in about 4% of SLE patients and rarely cause problems because they are not large and rarely embolize.

系统性红斑狼疮病人仅有4%出现，并且赘生物小不易脱落，因此对机体的影响较小。

The friability explains how portions of the vegetation can break off and embolize.

由于赘生物的易碎，因此极易脱落和引起栓塞。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
