骨髓于细胞移植治疗慢性下肢缺血性疾病

动脉粥样硬化及血栓闭塞性脉管炎所引起的慢性下肢缺血在临床上最常见,对于血管流出道好的采用血运重建或介入下球囊扩张及支架置入,但对于血管流出道差的严重慢性下肢缺血上述方法 则不适用.干细胞移植是近年来发展起来的新技术,它是利用于细胞多重分化括性及高度自我更新的潜能,定向分化为具有血管活性的内皮细胞,在治疗慢性下肢缺血性疾病中有很好的前景.

Transplantation of bone-marrow stem cell on chronic lower extremity ischemia

Atheroselerosis and thrombangiitis obliterans are the chief factors of chronic lower extremity ischemia. Usually we utilize intervcntional treatment which includs balloon dilatation and stent implantation or surgical revascularization for the patients who have good target vessels, but those methods are not suitable for the patients who have small target vessels. The transplantation of bone marrow stem cells is the new tech-nology for chronic lower extremity isehemia, which utilize the capacity of stem cells that have multiple differ-entiation activity and high self renewal potentiality. It can direetionally differentiated into endothelial cells. It has a good perspective in chronic lower extremity isehemia.
