Two-year Mortality in CLTI Patients Provide Crucial Factors We Should Fight

As mentioned by Hata et al., 2-year mortality in patients with chronic limb-threatening ischemia (CLTI) is an important factor for understanding the management of CLTI. In the 2007 Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial, it was reported that bypass surgery is appropriate as first-line revascularization if CLTI patients have durable veins and an expected life expectancy of > 2 years. Additionally, the European Society of Cardiology guidelines and the 2005 American College of Cardiology Foundation/American Heart Association updated guidelines were revised to indicate that life expectancy of > 2 years is an important factor for the initial revascularization in CLTI patients. However, this concept is extremely limited because there is no obvious definition of 2-year life expectancy.
