Role of Extracranial Ultrasound and Angioscopy in Thrombolytic Therapy
Thrombolysis as a stroke therapy means, more or less, the acute and aggressive treatment of the embolic occlusion. The majority of emboli go directly to the intracranial arteries, because the size of the embolic material is not large enough to obstruct the diameter of the extracranial arterial portion, especially the carotid bulb. Consequently, in the overwhelming majority of acute embolic stroke, thrombolysis must take place intracranially, and thus extracranial ultrasound plays only a minor role in diagnosing and monitoring the distal obstruction indirectly. The better access to the extra-cranial occlusions is used to a much lesser extent.
