Figure 2: Sequence of events with alteration in blood flow in a vascular territory flap before and 7 days after flap elevation. Figure shows the sequence of changes in choke vessels pre- and post-flap elevation in plastic and reconstructive surgeries. (A) Shows choke vessels under normal physiological conditions where they encounter balanced pressure from source arteries. (B) Immediately after flap elevation there is a disbalance in pressure in choke zone and there is increased blood flow in choke vessels. (C) 7 days after flap elevation choke vessels become tortous with increase in vessel wall thickness and diameter, transforming into functional arteries
