Objective To explore the effect and evaluation criterion of the transplantation of autologous peripheral blood stem cells(PBSC)for blood flow remodeling in the critical limb ischemia (CLI).
MethodsThirty six patients with 39 limbs suffered from CLI at Yunnan Provincial Center of Vascular Surgery and Department of Vascular Surgery of The First Affiliated Hospital of China Medical University from March 2003 to January 2007 were included in this study.These patients were divided into two groups. One groupconsisted of 20 cases in all 22 limbs used the transplantation of autologous PBSC,and another group included 16 cases in all 17 limbs were not use this technique.Multifunction monitoring device,dopplor ultrasound monitoring device,per cutem oxygen partial pressure monitoring device and digital subtraction angiography were used to measure effect degree of limbs regional blood flow from cutaneous covering,blood vessel and blood on the preoperative and postoperative days and the follow-up time was six months.
ResultsThe effect indexes of limbs regional blood flow of the case by transplantation of autologous PBSC was as follows:skin temperature index(STI)was(1.5±0.3) ℃, per cutem oxygen partial pressure monitoring device(TcPO2)was(36.6±9.3)mm Hg,ankle-brachium index(ABI)was0.7±0.1,photoplethysmograpy index(PPGI) was0.8±0.1,saturation of blood oxygen(SaO2)was(78.3±15.9)%,digital subtraction angiography score was1.5±0.3,the rate of limbs salvage was 82%,the distance of intermittent claudication was(150.3±41.1)meters,and the change of index was consistent with ameliorative tendency of symptom(0.415<r<0.592, P<0.05).
ConclusionThe transplantation of autologous PBSC can promote blood flowremodeling in limbs
ischemia,and the effect indexes of limbs regional blood flow can objectively reflect the degree of blood flow remodeling.
