Arterial System

INTRODUCTION:The posterior communicating artery is the main anastomotic channel of circle of willis.It joins internal carotid artery and vertebra-basilar arterial system. The size of posterior communicating artery varies frequently.The hypoplasia or aplasia of posterior communicating artery can detrmine the prognosis of neurological diseases. AIM:To study the variations and caliber of posterior communicating artery MATERIALS AND METHODS: A total of 104 specimens were collected,cleaned ,dissected and xed in formalin.Anatomical variations and caliber of posterior communicating artery were carefully recorded and photographed. RESULTS: In the present study,the hypoplasia of posterior communicating artery was one of the frequent variations which were observed in 16.7% of the subjects followed by aplasia in 15.5% and duplication in 1% . CONCLUSION: Awareness of these variations is important in diagnosis of neurological disorders and in neurovascular surgeries.

Abstract This 41-years-old female presented with somnolence, confusion and nuchal rigidity. Preoperative angio-CT scan showed two aneurysm located on both internal carotid artery (ICA) at the site of posterior communicating artery (PComA). During surgery we discovered another dilatation on the origin of left ophtalmic artery that proves to be an infundibullum. We clipped the two communicating posterior aneurysm from the left side and the ophtalmic infundibullum was wrapped. Seven days after surgery the neurological status was improved and she was transferred to the Neurological department.

Abstract Intraoperative oculomotor nerve injury in a patient with a true posterior communicating artery aneurysm is reported in detail. A comparison of internal carotid artery aneurysms at the posterior communicating artery junction with true posterior communicating artery aneurysms deserves special attention, because the vascular relationships of the aneurysm are more complex. A clip along the internal carotid artery does not occlude blood flow to the aneurysm, and the aneurysmal neck and the distal posterior communicating artery are closer to the oculomotor nerve. This is the 27th reported case of a true posterior communicating artery aneurysm. The incidence of true posterior communicating artery aneurysms ranges from 0.1 to 2.8% of all aneurysm patients. Such aneurysms constitute 4.6 and 11% of so-called posterior communicating aneurysms in two series. Difficulty associated with a preoperative diagnosis has been documented in at least 4 cases. An awareness of this rare aneurysm is stressed in order to avoid operative complications.

Embolization Procedure

Abstract OBJECTIVE AND IMPORTANCE Traumatic carotid-cavernous fistula (CCF) is currently treated with interventional neuroradiological embolization procedures. A rare case of posttraumatic CCF that resulted from an intradural pseudoaneurysm is presented. The patient was treated by direct surgery because an embolization procedure was not suitable. CLINICAL PRESENTATION A 16-year-old boy developed chemosis in the right eye 17 days after a traffic accident. Angiography revealed a pseudoaneurysm that arose from the site of origin of the posterior communicating artery, drained directly into the cavernous sinus, and formed a high-flow CCF. INTERVENTION Direct surgery was performed to repair the arterial laceration at the junction of the internal carotid artery and the posterior communicating artery. A clip was applied along the internal carotid artery. The posterior stump of the damaged posterior communicating artery was also included in the clip. Postoperatively, the CCF and pseudoaneurysm were completely obliterated, and the symptoms were cured. CONCLUSION Awareness of an unusual intradural origin of a CCF and the possibility of a direct surgical treatment should be kept in mind.
