ABSTRACT
PURPOSE:
Sometimes, intracranial pathology in the distal vasculature cannot be accessed by standard endovascular techniques because of occlusion or insurmountable tortuosity of theinternal carotid artery (ICA). A trans-sphenoidal surgical approach can follow a similar trajectory to the course of the supraclinoid ICA. This study evaluates the feasibility of a trans-sphenoidal approach to the supraclinoid ICA for endovascular access. MATERIALS ANDMETHODS:
In a fresh cadaver head, the sphenoid sinus was dissected through a trans-sphenoidal route. Bone over the carotid prominence was removed to expose the ICA. The artery was catheterized using the Seldinger technique, and three-dimensional digital subtraction angiography was performed to evaluate the procedure.RESULTS:
The catheter was successfully inserted into the supraclinoid ICA via the trans-sphenoidal route. Three-dimensional radiographic reconstruction confirmed placement of the catheter and the trajectory of the sheath into the supraclinoid ICA.CONCLUSION:
While the trans-sphenoidal route has innumerable disadvantages over the standard endovascular access techniques, this route could be considered when other treatment options are too risky or impractical.
