Microsurgical Clip Reconstruction of a True Posterior Communicating Artery Aneurysm.

Approximately 25% of intracranial aneurysms originate at the internal carotid artery and posterior communicating artery (PCoA) junction. In contrast to typical PCoA aneurysms, which are usually saccular, a subset known as true PCoA aneurysms arise directly from the PCoA. These represent about 1.

How I do it: The microsurgical clipping of the giant paraclinoid aneurysm using the retrograde suction decompression technique.

Background: Paraclinoid aneurysms account for 5.4% of all intracranial aneurysms. Giant aneurysms are found in 49% of these cases.

Management of postoperative CSF rhinorrhea after retrosigmoid craniotomy: how I do it.

Background: Cerebrospinal fluid (CSF) rhinorrhea as a complication of retrosigmoid craniotomy does not occur often today. This complication is primarily associated with the petrous bone drilling during surgery.

Method: The management of this complication is shown by the example of the patient with a trigeminal schwannoma located in posterior cranial fossa operated through resrisigmoid craniotomy.

Case Report: Simultaneous Resection of Bone Tumor and CAD/CAM Titanium Cranioplasty in Fronto-Orbital Region.

Simultaneous resection of bone tumors in the fronto-naso-orbital region is a great challenge due to the need for adequate reconstruction of the facial skeleton. Pre-operative virtual planning of resection margins and the simultaneous fabrication of the cranioplasty using computer-aided design/computer-aided manufacturing (CAD/CAM) technology could allow combining the tumor resection and cosmetic restoration steps into a single procedure. We present five consecutive cases of patients with bone tumors of the fronto-naso-orbital region.
