Brief summary
Endovascular revascularization is an effective procedure in treatment of chronic critical limb ischemia. The less invasive procedure in high risk patients produce the benefit to the patients. However, some of the patients cannot tolerate local anaesthesia. These patients need sedation or even general anaesthesia, which increase unnecessary risk to the patients. This study is conducted to evaluate the benefit of popliteal sciatic nerve block or popliteal block compare to sedation in critical limb patients undergoing angioplasty.
Interventions
PROCEDUREPopliteal block
Sciatic nerve block at popliteal fossa would perform before the participant undergoing angioplasty in experimental arm.
OTHERControl
Sciatic nerve at popliteal fossa would be scanned with the ultrasound. The toothpick would be applied to simulate the procedure of nerve block.
