Objective:
To discuss the technique details of subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) to improve technical success in the treatment of chronic total occlusions (CTO) diseases in lower extremity when there is failure to reenter the distal true lumen.
Methods:
Between May 2009 and Aug 2010, 15 patients underwent endovascular recanalization with SAFARI technique. There were 8 male and 7 female patients with a mean age of 74.9 years. There were 3 patients with severe claudication (Rutherford category 3) and 12 patients with critical limb ischemia (Rutherford category 4 to 6). The clinical and follow-up data of these patients were analyzed retrospectively.
Results:
Fourteen patients were treated with SAFARI technique successfully. The technique success rates were 93.3%. The mean ankle brachial index increased from 0.39 to 0.83.Symptoms were relieved in 86.6% patients, Ulcer were healed in 93.3%patients.
Conclusions:
SAFARI technique is a safe and effective method in treating CTO diseases, when it is failure to renter the distal true lumen with subintimal angioplasty technique.
