Deep Arteriovenous Malformations
15 Deep Arteriovenous Malformations Microsurgical Anatomy Brain Deep arteriovenous malformations (AVMs) are situated in the insula and central core of the hemisphere. Although these areas lie beneath portions of frontal,…
Brainstem Arteriovenous Malformations
16 Brainstem Arteriovenous Malformations Microsurgical Anatomy Brain Structures in the posterior fossa occur in “3’s.” The brainstem is composed of midbrain, pons, and medulla; superior, middle, and inferior cerebellar peduncles…
Parieto-Occipital Arteriovenous Malformations
13 Parieto-Occipital Arteriovenous Malformations Microsurgical Anatomy Brain Divisions between the parietal and occipital lobes are somewhat arbitrary. Although they are divided by the parieto-occipital sulcus on the medial hemisphere, there…
Cerebellar Arteriovenous Malformations
17 Cerebellar Arteriovenous Malformations Microsurgical Anatomy Brain The cerebellum is composed of two hemispheres joined in the midline by the vermis (Fig. 17.1). The cerebellum has three surfaces: suboccipital, tentorial,…
Temporal Arteriovenous Malformations
12 Temporal Arteriovenous Malformations Microsurgical Anatomy Brain The temporal lobe has four surfaces: lateral, basal, sylvian, and medial (Fig. 12.1). The lateral temporal surface consists of three horizontal gyri that…
Frontal Arteriovenous Malformations
11 Frontal Arteriovenous Malformations Microsurgical Anatomy Brain The frontal lobe has four surfaces: lateral, medial, basal, and sylvian (Fig. 11.1). The lateral surface is composed of three horizontal gyri (superior,…
Ventricular and Periventricular Arteriovenous Malformations
14 Ventricular and Periventricular Arteriovenous Malformations Microsurgical Anatomy Brain The cerebrum separates neatly into frontal, temporal, and parieto-occipital lobes, and arteriovenous malformations (AVMs) located in the cerebral hemispheres are based…
