Magnetic resonance findings in spontaneous dissection of the cervical internal carotid artery--case report

Traumatic vascular injuries and their management

Traumatic vascular injury to the intracranial and extracranial circulation can be sequelae of blunt, penetrating, or iatrogenic insults to the head, face, or neck. Treatment options include conservative medical management, or more invasive surgical or endovascular therapy. The appropriate treatment depends on the risk-benefit ratio of each option considering the natural history of each. Injuries include mild intimal irregularities, intimal flaps, pseudoaneurysms, fistulas, and occlusions. Need for treatment is partly determined by the collateral circulation to the brain, and the degree to which the lesion is thrombogenic. Advances in endovascular devices and techniques provide us with less invasive alternatives to surgery intervention or allow the interventionalist to treat lesions not treatable by any other modality.

Endovascular therapy of traumatic injuries of the extracranial cerebral arteries

The field of neuroendovascular therapy is rapidly growing. New technology and operators' expertise are developing at a pace that will make this discipline progressively more available and successful. For patients who have traumatic injuries of the extracranial arteries, endovascular therapy offers a new dimension to the treatment of these injuries and the prevention of stroke. Because many of these patients are likely to be critically ill, it is important to keep in mind the principles of their management before, during, and after the procedure, thus assuring the best chance for a successful outcome. Furthermore, some of the issues related to their neurointensive care will serve as guides for the need for endovascular therapy, as well as its timing.
