Morphological and Hemodynamic Parameters for Middle Cerebral Artery Bifurcation Aneurysm Rupture Risk Assessment
OBJECTIVE To investigate the morphological and hemodynamic parameters associated with middle cerebral artery (MCA)bifurcation aneurysm rupture. METHODS A retrospective study of 67 consecutive patients was carried out based on 3D digital subtraction angiography data. Morphological and hemodynamic parameters including aneurysm size parameters (dome width, height, and perpendicular height), long...
متن کاملThe transsylvian approach to middle cerebral artery bifurcation/trifurcation aneurysms.
A transsylvian approach to treat aneurysms located at the bifurcation/trifurcation of the middle cerebral artery (MCA) is described. This surgical route traces a distal MCA branch retrogradely into the Sylvian fissure whereupon a secondary MCA branch and the main stem of the MCA (M1) are identified before aneurysm clipping. The advantages, and disadvantages of this approach are discussed. The t...
متن کاملA New Classification Of Unruptured Middle Cerebral Artery Bifurcation Aneurysms
MCA aneurysms comprise 20% to 25% of intracranial aneurysms.Majority of middle cerebral artery aneurysms are treated with microsurgical clipping. Most of the classifications are based on size, location or pathology which are effective for description but are less useful in preoperative planning and also in deciding the technique or type of clip application. The aim of our study was to study the...
متن کاملVariation in Bifurcation Pattern of Brachial Artery
Recognizing the arterial variations of human upper extremities is of potential clinical practice because this area is involved in arterial handling and invasive medical procedure. During dissection of the left upper limb of a 35-year-old male embalmed cadaver, we saw brachial artery bifurcation in the middle third of proximal portion of the arm. Its medial branch descended along the medial side...
متن کاملRuptured middle cerebral artery bifurcation aneurysm manifesting as caudate head hemorrhage extending into the ventricle: case report and literature review
Ruptured intracranial aneurysm usually manifests as subarachnoid hemorrhage (SAH) or SAH with hematoma. Aneurysms that only present with intracerebral hemorrhage or intraventricular hemorrhage are mostly confined to the distal artery. It is very rare that ruptured middle cerebral artery bifurcation aneurysms manifest signs of caudate head hemorrhage extending into the cerebral ventricle. One su...
