[The influence of various factors on results of subintimal angioplasty of superficial femoral artery occlusions].
OBJECTIVE
To evaluate prospectively the impact of various factors on subintimal angioplasty of superficial femoral artery.


METHODS
Within a period of 36 months, 44 patients with 45 chronic occlusions in superficial femoral artery were examined. The influence of sex, age, hypertension, diabetes mellitus, smoking, chronic ischemia stage, occlusion length and calcification, flush occlusion of the superficial femoral artery, ischemic cardiac disease, postprocedural medical treatment was evaluated.


RESULTS
Arterial calcification had a significant impact on technical success of subintimal angioplasty (p=0.03). Sex, age, smoking, flush occlusion of the superficial femoral artery, and cardiac disease influenced technical and hemodynamic success (p=0.086-0.295). Hypertension, diabetes mellitus, chronic ischemia stage, occlusion length, and postprocedural medical treatment did not significantly influence technical and hemodynamic success (p>0.05).


CONCLUSIONS
Arterial calcification had a significant impact on technical success of subintimal angioplasty. Sex, age, smoking, flush occlusion of the superficial femoral artery, and ischemic cardiac disease influenced technical and hemodynamic success. Hypertension, diabetes mellitus, chronic ischemia stage, occlusion length, and postprocedural medical treatment had no statistically significant impact on technical and hemodynamic success.
