*8.5.2 Indirect revascularization*

The various surgical procedures are


The last two surgeries are performed as primary or after failed revascularization by other techniques.

Indirect revascularization is relatively easier to perform than direct surgeries, and the incidence of hyperperfusion is also less. However, the improvement in cerebral revascularization takes longer than the direct surgeries where the effect is immediate.

After indirect revascularization, patients experienced 0–14.3% postoperative annual stroke rate [41].

Thus either of the indirect and direct revascularization procedures can be performed to rectify the underlying pathology, but the risk of recurrence is much less with the direct revascularization surgeries without any delay to the benefit.
