Microsurgical single-stage repair of pericallosal artery multiple aneurysms
Keywords:pericallosal artery, arterial aneurysm, inter-hemisphere fissure
Nowadays there are two methods of surgical treatment of brain arterial aneurysms (AA): microsurgical transcranial and endovascular. Method selection is based on AA morphological, anatomical and topographical characteristics and estimation of patients’ condition.
Aneurysms of pericallosal arteries (PCA) are revealed in 2–6% cases of all intracranial AA.
In 15% cases in the structure of multiple AA of distal segments of anterior cerebral artery aneurysms are located only on the A3 segment of pericallosal artery, among them 71% — on the opposite side, 29% — on the same side.
An observation of multiple aneurysms of PCA A3 segment transcranial single-stage microsurgical turn off from the blood flow is given. Aneurysms were located on opposite arteries, two — on the right, and one — on the left side. Microsurgical approach to PCA in inter-hemisphere fissure was used, AA were clipped.
The patient was operated urgently due to her critical condition.
Complex clinical and instrumental examination allowed to choose method of surgical treatment (transcranial microsurgical), to determine an optimal surgical tactics (single-stage turn off) and to plan surgery.
