Microsurgical Treatment of Ruptured True Posterior Communicating Artery Aneurysm in the Distal Portion of the Posterior Communicating Artery

摘要

The true posterior communicating artery (PCoA) aneurysms in the distal portion of the posterior communicating artery are rare. The authors describe a 63-year-old woman with 1 true PCoA aneurysms in the distal portion of the PCoA, which was treated surgically through modified pterional approach. No neurologic deficit was present at the postoperative period. Although endovascular intervention is more and more widely used in the treatment of aneurysms, the authors have also emphasized that true PCoA aneurysms in the distal portion of the PCoA can also be surgically treated in suitable patients.
