Unusual Nerve-Artery Relationship in Microvascular Exploration for Tic Douloureux

Neurovascular decompression with selective partial rhizotomy of the trigeminal nerve for tic douloureux.

Fourteen patients with classic tic douloureux were treated with neurovascular decorapression of the trigeminal nerve at its zone of entry into the pons. In addition, selective rhizotomy of the portio major was performed in each patient. This combined procedure gave excellent relief of pain with no recurrences in a 23-month postoperative period. Technical observations and postoperative complicat...

Dolichoectasia of vertebrobasilar system: a rare cause of tic douloureux.

The usual outcome of rudimentary horn pregnancy is rupture in second trimester in 90% of cases.[1] Early diagnosis of this rare form of pregnancy prior to rupture is essential for successful management in order to prevent maternal morbidity and mortality.[2] Though uterine anomalies can be suspected on bimanual or ultrasonographic examination,[2,3] these can be diagnosed in only 14% cases befor...

The differential diagnosis and treatment of tic douloureux.

Electromagnetic Induction Aberration: The Possible Mechanism of Tic Douloureux

A theory based on the principles of electromagnetic induction aberration is presented as the possible mechanism of classic trigeminal neuralgia, tic douloureux. The anatomy of the dorsal root entry zone of the trigeminal nerve at the pons in the proximity of the superior cerebellar artery presents a scenario conducive to the phenomenon of electromagnetic induction. When the action potentials tr...

Identification of Meckel cave during percutaneous glycerol rhizotomy for tic douloureux.

A new percutaneous treatment of tic douloureux has been developed . Transovale injection of glycerol into the retrogasserian trigeminal fibers in Meckel cave results in complete pain relief in 77%-89% of patients [1-3]. The major advantages of percutaneous retrogasserian glycerol rhizotomy include simplicity, radiograph ic confirmation of accurate need le placement, and a much reduced incidence...
