There is limited information on BTK artery variants and comparative outcome of endovascular revascularization of BTK arteries in men and women.
We analyzed core laboratory adjudicated angiographic data from BTK interventions included in the Excellence in Peripheral Artery Disease (XLPAD) registry between January 2006 and March 2015. BTK arteries were classified into Type I (based on BTK origin), Type II (based on above-the knee origin) and Type III (based on hypoplastic arteries) anatomical variants, and lesion severity in men and women. 12-month major adverse limb events (MALE) are reported for BTK interventions in men and women.
Distribution of 398 BTK arteries (559 patients) in each anatomical type and lesion severity grade from 275 men and 123 women is shown in Figure 1a. Frequency of Types II (3.9% vs. 4.2%) and III (3.2% vs. 1.7%) were similar in men and women, respectively, hypoplasia of anterior tibial artery (4.7% vs. 2.4%; p=0.02) and posterior tibial artery (3.2% vs. 0%; p=0.003) was more commonly observed in men. Presence of heavy calcification (75% vs. 24%; p=0.001) and chronic total occlusion or CTO (75% vs. 25%; p=0.001) were more frequently reported in men. 12-month MALE (a composite of all-cause death, need for endovascular target lesion /surgical revascularization and any amputation) were more in men (17%) than in women (7%; OR=1.17; 95%CI: 0.79-1.95; p=0.5; Figure 1b).
There are important gender differences in anatomical variations, lesion types of BTK arteries and 12-month MALE in patients referred for endovascular revascularization of BTK arteries.
