Brief Summary:

Patient with occluded below the knee arteries and chronic limb ischemia Rutherford class V-VI are enrolled.

During endovascular recanalisation procedure changes in tissue oxygen amount is recorded using near infrared spectroscopy (NIRS).

Primary hypothesis - NIRS can be used to determine sufficient amount of blood reaching the ulcered ishemic area.

Secondary hypothesis - NIRS can be useful in detecting early recoil after BTK recanalisation.
