[Diagnosis of middle cerebral artery spasm by determination of flow velocity and the Lindegaard index with transcranial color Doppler sonography].
Recent reports have demonstrated the high utility of transcranial color-coded duplex sonography (TCCS) in the diagnosis of advanced spasm of the middle cerebral artery, whereas its accuracy in the diagnosis of mild vasospasm is reported to be lower. Relation of blood flow velocity in the middle cerebral artery (MCA) to that in the extracranial internal carotid artery (VMCA/VICA index) is recommended as being helpful in the diagnosis of vasospasm (the so called Lindegaard Index). Nevertheless, the exact diagnostic value of this index using the TCCS method remains to be established. The purpose of this study is to estimate the accuracy of TCCS in the diagnosis of MCA vasospasm, as based on the VMCA/VICA index. ⋯ The use of VMCA/VICA index improves the accuracy of TCCS in the diagnosis of mild vasospasm of the middle cerebral artery.

The association between migraine and functional gastrointestinal disorders has been confirmed by many clinical observations and epidemiological studies. In most patients during the attacks of migraine, apart from various neurological and vascular symptoms, gastrointestinal disturbances occur including nausea, vomiting, abdominal pain or diarrhea. Functional gastrointestinal disorders, such as irritable bowel syndrome (IBS), are reported in migraine patients in periods between the attacks as well. ⋯ Nowadays, agonists and antagonists of serotoninergic receptors are the most efficacious drugs for IBS and migraine therapy. Some side effects of triptans, 5-HT(1B/D) agonists, used in migraine treatment may be connected with the influence of triptans on the gastrointestinal functions. A better understanding of the relationship between migraine and IBS may result in more effective treatment of both diseases.
