[EC-IC bypass for occlusion of the internal carotid artery].

BACKGROUND

There are barely any alternative treatment options to the drug treatment of hemodynamically caused cerebral ischemia, as in occlusion of the internal carotid artery.

OBJECTIVE

For secondary prevention of an ischemic stroke due to carotid occlusion and hemodynamic instability, extracranial-intracranial (EC-IC) bypass surgery can be an important option in selected patients.

MATERIAL AND METHODS

The development, study situation, indications and surgical technique for placement of an EC-IC bypass in cases of occlusion of the internal carotid artery are presented.

RESULTS

With appropriate expertise and strict selection of patients, the placement of an EC-IC bypass enables stabilization of cerebral perfusion with a low rate of complications.

CONCLUSION

The study situation is controversially discussed; nevertheless, surgical treatment in a specialized neurovascular center should at least be considered.
