Microvascular decompression for trigeminal neuralgia using the 'Stitched Sling Retraction' technique in recurrent cases after previous microvascular decompression.
Microvascular decompression is a well-known therapeutic option for trigeminal neuralgia. It is considered safe and effective, and is the surgical treatment of choice for the malady. However, there is no standard technique for it and different authors have proposed different techniques of performing it. In this study, we observe the clinical results of the so-called 'stitched sling retraction' technique for recurrent cases of trigeminal neuralgia. ⋯ The 'stitched sling retraction' technique shows promising preliminary results in recurrent cases of trigeminal neuralgia after previous microvascular decompression(s). Since it is a 'transposing' technique, it might be associated with less recurrence rates (due to resuming of the neurovascular conflict) than the classic interposing technique, which uses a prosthesis between the offending vessel and the trigeminal nerve.

Review Case Reports
Symptomatic vertebral artery loop: a case report and review of literature.
Vertebral artery loop formation is a rare anatomical variant capable of causing bony erosion, encroachment on cervical neural foramen, neurovascular compression, or vertebrobasilar insufficiency. Health professionals should keep the diagnosis of vertebral artery loop formation in mind, especially when the plain radiograph of the cervical spine shows enlargement of the intervertebral foramen. ⋯ This case report aims at increasing the awareness of both clinicians and radiologists of this entity as a known rare cause of cervical radiculopathy. In suspected cases, Magnetic resonance imaging & Magnetic resonance angiography should always be the first choice in this regard.

Continuous intraoperative monitoring of abnormal muscle response in microvascular decompression for hemifacial spasm; a real-time navigator for complete relief.
Intermittent monitoring of abnormal muscle response (iAMR) has been reported to be useful for improving the surgical outcome of microvascular decompression (MVD) for hemifacial spasm (HFS). However, iAMR has not elucidated the relationship between AMR change and the corresponding surgical procedure, or the pathogenesis of AMR and HFS. The purpose of this study is to clarify the usefulness of continuous AMR monitoring (cAMR) for improving the surgical results of MVD and for understanding the relationship between AMR change and corresponding surgical procedure, and the pathogenesis of AMR and HFS. ⋯ Facial spasm remained in four patients despite permanent AMR disappearance. cAMR monitoring improves the outcome of MVD. Although the main cause of HFS and AMR is vascular compression at the facial nerve, hyperexcitability of the facial nucleus is also involved in the pathogenesis of HFS and AMR. The proportional involvement of these causes differs between patients.

Microvascular decompression (MVD) is an established surgical therapy for patients with idiopathic trigeminal neuralgia (TN). The role of MVD in patients with definite or suspected multiple sclerosis (MS) remains controversial. ⋯ Facial pain outcomes after MVD in patients with suspected MS-related TN are poor compared with outcomes for patients with idiopathic TN. This study provides further support that many patients with MS-related TN have pain that is centrally mediated, reducing the effectiveness of procedures performed on the trigeminal root, ganglion, or divisions.

The role of percutaneous balloon compression in the treatment of trigeminal neuralgia recurring after other surgical procedures.
Trigeminal neuralgia (TN) recurring after surgery can be difficult to treat. Treatment algorithms have not been standardized or universally accepted. Here we investigated the effectiveness of percutaneous balloon compression (PBC) in the treatment of patients with TN recurrence after other surgical techniques and analyzed the role of some clinical and operative factors in determining the prognosis. ⋯ No patients had an uncontrolled pain. The lack of history of MS (p = 0.0174), the pear-like shape of the balloon at the operation (p = 0.0234) and a compression time <5 min (p < 0.05) were associated to higher pain-free survival. Considering these results PBC could be considered a useful technique for patients whose pain recurs after other procedures.
