Which type describes an occlusion in the body of tibial arteries?

• A. Type 1
• B. Type 2
• C. Type 3
• D. Combined hybrid approach

Answer: (A)

Understanding where an occlusion sits within the tibial arteries is the key idea. When the blockage lies in the mid-section of the tibial arteries—the body or shaft of the vessel—it is categorized as Type 1. This distinguishes it from occlusions that occur right at the origin (ostial) or at distal segments near the ankle. The option describing a combined hybrid approach is about treatment strategy, not the lesion’s location, so it doesn’t describe where the occlusion is. So a mid-artery blockage in the tibial vessels fits Type 1.
