目的:了解介入性活检技术的可行性及分流道狭窄的组织构成,探讨分流道狭窄的形成机制。材料与方法:10例分流道狭窄或闭塞者,采用心肌活检钳和Simposon旋切导管经颈静脉途径对狭窄组织进行了活检,其中8例采用活检钳法,2例采用导管旋切法。所取病理标本行常规HE染色及免疫组化染色检查。结果:10例病人的介入活检操作全部成功,无并发症发生。光镜下狭窄组织主要为纤维结缔组织和不同机化阶段的血栓,并有大量泡沫细胞及炎性细胞。结论:1.介入性活检技术是安全而有效的活检方法;2.分流道内的狭窄与血栓的形成和机化有关。
OBJECTIVE: To understand the feasibility of interventional biopsy and the structure of shunt narrow and to discuss the formation mechanism of shunt stenosis. MATERIALS AND METHODS: Tissue biopsy was performed in 10 patients with narrow or occluded bypass. Myocardial biopsy forceps and Simposon revascularization catheter were used to biopsy the stenotic tissue. Among them, biopsy was performed in 8 cases and biopsy in 2 cases. Pathological specimens taken routine HE staining and immunohistochemical staining. Results: The interventional biopsy of 10 patients was successful and no complication occurred. Light microscopic stenosis mainly fibrous connective tissue and different stages of the thrombus, and a large number of foam cells and inflammatory cells. Interventional biopsy is a safe and effective biopsy method.2. The stenosis in the shunt is related to the formation and mechanization of thrombus.
