This article provides an in-depth review of carotid endarterectomy for the treatment of occlusive carotid disease. Topics range from preoperative diagnostic assessment to postoperative complications. Key issues related to operative management, including anesthetic technique, intraoperative monitoring, cerebral protection, anticoagulation therapy, and intraluminal shunting, are emphasized. Operative techniques are discussed and illustrated in detail.

ReviewThe role of angiography in the evaluation of cerebral vascular malformations.
Although magnetic resonance imaging has become the modality of choice for the diagnostic evaluation of cerebral vascular malformations, cerebral angiography remains indispensable for the evaluation of cerebral arteriovenous malformations. Super-selective angiography allows detailed endovascular exploration of the various vascular elements composing cerebral arteriovenous malformations and is essential in elucidating their angioarchitecture and for treatment planning. Clinicoangioarchitectural correlations further our understanding of the natural history of cerebral arteriovenous malformations.

Ameliorated computed tomography techniques and new magnetic resonance sequences have led to an important improvement in temporal bone imaging. Computed tomography is still the method of choice for imaging of temporal bone fractures, middle ear disease, and conductive hearing loss, although magnetic imaging can add important information. ⋯ In some cases, however, such as congenital malformations and petrous apex lesions, magnetic resonance imaging and computed tomography are complementary. The value of both modalities is discussed.

Recent changes in sinonasal imaging are a direct result of the development of functional endoscopic sinus surgery. Because of this technique, radiologists have noted an increased volume of sinus imaging, developed new imaging techniques, and are interpreting films in a different manner. This article covers the common variants seen on coronal computed tomography, discusses the complications of functional endoscopic sinus surgery, reviews the radiographic criteria for sinusitis, and addresses the role of computed tomography and magnetic resonance imaging in evaluating the sinonasal cavity.

ReviewRadiologic assessment of trauma and foreign bodies of the eye and orbit.
The detection and definition of orbital trauma is a frequent clinical problem. Therefore, the radiologic assessment is crucial. This article discusses the radiologic techniques and types of injuries that occur to the orbit.
