Abstract:

Objective:

To investigate the short-and-long-term effects of bidirectional intimal angioplasty - in clinical application of lower extremity arterial occlusive disease.

Methods:

A retrospective analysis was performed among 32 patients with lower extremity arterial occlusion who received subintimal arterial flossing with antegrade-retrgrade retrograde intervention (SAFARI) between June 2012 - August 2015 in our hospital.

Results:

The success rate of the treatment was 100%, with Fontaine grading levels of post-treatment I in 5 cases and II in 27 cases, showing a statistically significant difference compared with the preoperative data (Z=5.293, P <0.05), after ABI is (0.86±0.13), and preoperative (0.41±0.12) (t=4.923, P <0.05). A follow-up study showed that among the 32 patients after 13 to 29 months, one-year patency remained in 20 patients, two years in 16 cases. Based on the Kaplan-Meier curve analysis, the 1-year, and 2-year patency rate among these patients was 60.93% and 45.28%, respectively.

Conclusions:

The two-way subendometrial angioplasty treatment of lower extremity arterial occlusive disease is safe and effective.
