Surgical anatomy of petrous part of the internal carotid artery
نویسندگان
چکیده
Exposition of the petrous part of the internal carotid artery (pICA) necessitates close control during surgery for proximal internal carotid artery aneurysms. The most difficult manipulation is the exposure of the internal carotid artery on the level of the carotid canal, and in most cases it is accompanied by local neurological complications in postoperative period that are results of the trauma to the nerves during the dissection stage of the corresponding region. The purpose of our study was to investigate the anatomical relationships of the internal carotid artery in petrous part of the temporal bone in two segments: a vertical and a horizontal segment.

Accuracy of computer-aided geometric three-dimensional reconstruction of the human petrous bone based on serial unstained celloidin sections
The aim of this study was to present a comprehensive three-dimensional (3D) morphology of the petrous bone with computer image-processing technology, which could be beneficial for the teaching of anatomy and for surgical procedures. The unstained celloidin sections of human temporal bone were digitized with high resolution and quality, and then processed with Amira® software to include alignmen...

BACKGROUND AND PURPOSE The petrous and cavernous segments of the extradural internal carotid artery take a complex course through the skull base before entering the subarachnoid space distal to the cavernous sinus. Despite the protection from trauma afforded by the anatomy, the petrous and carotid internal carotid artery (ICA) segments of the vessel remains subject to disease, the most importan...
متن کاملCT of petrous carotid aneurysms.
Aneurysms arising from the petrous part of the internal carotid artery (ICA) are exceedingly uncommon. Only 21 angiographically proven cases have appeared in the literature [1-6) . The CT appearance of these rare lesions has not previously been reported. In the two cases described here, the CT pattern closely resembles that of the more common petrous apex meningioma. Consideration of a petrous ...
متن کاملAnalysis of the petrous portion of the internal carotid artery: landmarks for an endoscopic endonasal approach.
OBJECTIVES/HYPOTHESIS While there are many benefits to the endoscopic endonasal approach to the infratemporal fossa, involvement of the petrous portion of the internal carotid artery (ICA) poses a unique challenge. The endoscopic endonasal approach requires establishing the relationship of the petrous ICA to anatomical landmarks to guide the surgeon. This study evaluates the relationship of pet...
متن کاملBilateral aberrant internal carotid arteries with bilateral persistent stapedial arteries and bilateral duplicated internal carotid arteries.
A 5-year-old boy was evaluated for a left retrotympanic mass found at otoscopy. Subsequent petrous bone CT and MR angiographic examinations demonstrated bilateral aberrant internal carotid, bilateral stapedial artery persistence, and bilateral duplicated internal carotid arteries. Imaging findings and their clinical relevance are discussed. A second case of unilateral aberrant internal carotid ...
