Near Infrared Spectroscopy and Transcutaneous Oxygen Pressure in Critical Limb Ischemia Before and After Treatment

Comparison of Near Infrared Spectroscopy (NIRS) and Transcutaneous Oxygen Pressure (TCPO2) Measurements in Critical Limb Ischemia (CLI) Patients After Invasive Treatment (Endovascular or Surgery)

Comparison of two non-invasive methods for measuring tissue oxygenation. One is Transcutaneous Oxygen Pressure (TCPO2) and the other is the new method of Near Infrared Spectroscopy (NIRS) - near infrared spectroscopy in patients with critical limb ischemia (CLI) undergoing invasive treatment (surgical or endovascular).

Comparison of two non-invasive methods for measuring tissue oxygenation. One is TCPO2 and the other is the new method of NIRS - near infrared spectroscopy in patients with critical limb ischemia (CLI) undergoing invasive treatment (surgical or endovascular).

The NIRS probe has been used to measure tissue oxygenation in the cerebral circulation up to now. While TCPO2 is the established method for measuring tissue oxygenation in patients with CLI to evaluate the potential for wound healing.

Inclusion Criteria:

• 10 patients admitted to the vascular surgical department and undergoing invasive treatment (surgical or endovascular)

Exclusion Criteria:

• pregnancy allergy to iod advanced renal failure CCT<50 active peptic ulcer recent bleeding
