Hemifacial spasm consists of involuntary contractions of the facial muscles, usually caused by vascular compression of cranial nerve VII , near its exit zone from the brainstem [17]. Arteriovenous malformations (AVMs) are a rare cause of this condition [2, 3]. We report a case of hemifacial spasm caused by an extensive cerebellar AVM, which was successfully treated by intravascular embolization .

Coronary artery spasm after coronary artery bypass grafting (CABG) is a rarephenomenon often resulting in heart failure. We report a case of 56-yearr-old male, who had coronary artery spasm after CABG, which was successfully treated with intracoronary injection of nitroglycerine and heparin.

Objective—Phospholipase C1 activity is enhanced in patients with coronary artery spasm, and a p122 protein was recently cloned to potentiate phospholipase C1 activity. To investigate the role of p122 in enhanced vasomotility, we examined p122 expression in the cultured skin fibroblasts obtained from patients with and without coronary spasm, intracellular Ca concentration ([Ca ]i) at baseline an...

The present study investigated whether the circadian rhythm of sympathovagal activity is related to the severity of coronary spasm or multivessel coronary spasm. Heart rate variability was examined in 22 consecutive patients with vasospastic angina provoked by intracoronary injection of acetylcholine, who had either multivessel spasm (Group M, n=11 ) or single vessel spasm (Group S, n= 11), in ...

A type of rigid flat foot which is accompanied by contraction of the peroneal muscles has long been recognised. The etiology is obscure. Correction of the deformity seems to be prevented by tension of the peroneal muscles, and there has been wide acceptance of the thesis that the deformity is caused by peroneal muscle spasm induced by painful stimuli arising from the tarsal joints. It has been ...

Cerebrospinal fluid from patients with subarachnoid haemorrhage and cerebral arterial spasm contracted the isolated basilar artery and potentiated contractions produced by 5-hydroxytryptamine, noradrenaline, and six prostaglandins. The unidentified substance in cerebrospinal fluid probably plays a role in the aetiology of cerebral arterial spasm.

The correlation between obstructive sleep apnea (OSA) and hemifacial spasm has never been reported in the literature. Here, we report a case of OSA-induced hypertension with intractable hemifacial spasm in which both conditions improved after continuous positive airway pressure treatment.

We used neurointerventional techniques to conduct a functional investigation of the artery responsible for hemifacial spasm in a 48-year-old woman. Insertion of a microcatheter into the posterior inferior cerebellar artery stopped the hemifacial spasm immediately and completely. The artery was verified intraoperatively as the vessel compressing the root exit zone of the facial nerve.

Bell palsy occurs in different rheumatic diseases, causes hemifacial weakness, and targets the motor branch of the 7th cranial nerve. Severe, persistent, and refractory otalgia having features of neuropathic pain (ie, burning and allodynic) does not characteristically occur with Bell palsy. Whereas aberrant regeneration of the 7th cranial nerve occurring after a Bell palsy may lead to a variety...
