Which type describes flush/ostium occlusion of tibial?

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

Answer: (C)

The key idea is how tibial artery occlusions are categorized by where the blockage sits. A flush or ostial occlusion means the artery is blocked right at its origin from the parent vessel, with no proximal portion left open. In this labeling scheme, that pattern is described as Type 2. So Type 2 is the best match for flush/ostium occlusion of the tibial artery. This distinction matters because an ostial flush occlusion can be tougher to treat from a proximal approach since there’s no proximal landing zone to engage with wires or devices; clinicians may need alternative strategies, such as retrograde access or specialized wiring techniques. The other patterns describe different lesion locations or approaches (for example, a long diffuse occlusion away from the origin, or a treatment strategy rather than a lesion type), so they don’t match the described flush/ostial pattern.
