Abstract
Angioneurotic headache is a common headache type in clinical treatment. At present, patients with nervous headache are mainly treated with oral western medicine in clinic, but it is usually difficult to obtain the ideal effect. In this study, we analyzed the effects of continuous lidocaine infusion through an ultrasound-guided cervical sympathetic ganglia (SG) catheter on cerebral hemodynamics and thermal imaging characteristics of head and neck in patients with angioneurotic headache and explored the clinical feasibility of this scheme. The results show that continuous infusion of lidocaine under ultrasound-guided SG catheterization can alleviate headache in patients with angioneurotic headache, which may be related to improving cerebral hemodynamics.
