Background: To study the microsurgical anatomy of supraclinoid ICA, the size and number of perforators, any anomalies in normal anatomy of ICA, its branches and surrounding structures in North West Indian population.
Materials and Methods: Twenty cadaveric brain dissections were performed under operating microscope (Carl ZeissNC31). Sylvian fissure was meticulously dissected from distal to proximal. Anterior clinoid process (ACP) was drilled intradurally using M-80 pneumatic drill. Vessels, their branches and perforators were dissected with measurement of their length, diameter and number. Supraclinoid ICA was dissected till its bifurcation into anterior and middle cerebral arteries. The length of falciform ligament was also measured.
Results: The length of ophthalmic segment was largest varying from 5.5 to 13.0 mm (average 9.75mm).The communicating segment was the shortest varying from 1.5 to 6.0 mm (average 3.2mm). The number of perforating arteries excluding the OphA, PComA and AChA arising from C4 varied from 3-10(average 6). The maximum perforators were from Cho Seg and least from Com Seg.
Conclusion: The overall anatomical details of supraclinoid ICA in North West Indian population were comparable to existing literature.
