Pedal and plantar loop angioplasty: technique and results.

Endovascular and subintimal approaches fails in obtaining a below-the-knee recanalization in 10-40% of cases, even in high-volume and expertise centers. The presence of long calcified occlusions, characterized by a complex anatomy, often necessitate the use of alternative techniques in order to obtain a direct blood flow to the foot arteries. Recanalization using pedal and plantar loop angioplasty could improve outcomes in the presence of a communication between the dorsal and plantar arch of the foot, if conventional techniques are not effective.
