Objective : We assessed the surgical results of percutaneous balloon compression in 50 patients with idiopathic trigeminal neuralgia. Methods : Fifty patients with follow-up period of more than 12 months were retrospectively analyzed. The mean follow-up period was 42 months (range, 12-82). The mean age was 65.8 years (range, 27-83). Seventeen patients (34%) had other previous surgical procedures. The balloon was inflated by injecting radio-contrast media under brief general anesthesia according to Mullan’s technique. The mean inflating time was 88 seconds (range, 60-120). The whole procedure took about 20 minutes. Results : We reported excellent and good results in 70% of the cases, poor in 6% as annoying dysesthesia, recurrence in 16%, and 8% failure due to technical deficiencies. Forty-six patients (92%) were initially relieved of their pain. There were permanent motor weakness of the masseter muscle in 4% of patients and transitory diplopia in 8%. Neither anesthesia dolorosa nor keratitis occurred. Almost all patients (92%) were discharged postoperatively within two days. Conclusion : These results indicate that balloon compression would be an effective method with acceptable morbidity, technically, It can be performed rapidly and simply in the treatment of idiopathic trigeminal neuralgia.

Objective : To prospectively compare facial pain outcomes for patients having either a repeat microvascular decompression (MVD) or percutaneous balloon compression (PBC) as their surgery for trigeminal neuralgia (TN) recurrence. Methods : Prospective cohort study of 110 patients with TN recurrence who had either redo MVD (n=68) or PBC (n=42) from July 2010 until September 2016. The mean follow-up was 45.6 months. Results : After redo MVD, 65 patients (95.6%) experienced immediate relief of pain. After PBC, 34 patients (81%) were immediately relieved of their neuralgia. After 1 month, the clinical effect of redo MVD was better than PBC (p<0.01). Patients who had redo MVD more commonly were pain free off medications (93.4% at 1 year, 78.2% at 4 years) compared with the PBC patients (85.1% at 1 year, 59.3% at 4 years). However, mean length of stay was longer (p>0.05). Patients after PBC who occurred developed herpes simplex (35.7%), facial numbness (76.2%), and annoying dysesthesia (21.4%) more frequently compared with patients after redo MVD who occurred developed herpes simplex (14.7%), facial numbness (8.8%), and hypoesthesia (5.9%) (p<0.05). The symptoms recurred respectively in 15 patients (22.1%) and 19 patients (45.2%) after redo MVD and PBC within the entire 6-year follow-up period. Conclusion : For the patients with TN recurrence, redo MVD was a more effective procedure than PBC. The cure rate and immediate relief of pain were better, and the incidence of complications was lower.

Percutaneous vertebroplasty and balloon kyphoplasty have been accepted as effective treatment modalities for vertebral compression fractures in patients with vertebral metastasis. However, when these procedures are conducted in patients with lytic lesions of the vertebral pedicle, polymethylmethacrylate leakage through the lytic lesions that occurs during percutaneous pediculoplasty can increase the procedural risks due to the immediate vicinity of neural structures. In spite of this risk, there are not many available reports on safer methods of pediculoplasty. Here we report a case of vertebral metastasis in which the pedicle infiltration of cancer was successfully treated by pediculoplasty using a bone filler device that contained thick bone cement during a balloon kyphoplasty procedure.

Epidural adhesions cause pain by interfering with the free movement of the spinal nerves and increasing neural sensitivity as a consequence of neural compression. To remove adhesions and deliver injected drugs to target sites, percutaneous epidural adhesiolysis (PEA) is performed in patients who are unresponsive to conservative treatments. We describe four patients who were treated with a newly developed inflatable balloon catheter for more effective PEA and relief of stenosis. In the present patients, treatments with repetitive epidural steroid injection and/or PEA with the Racz catheter or the NaviCath did not yield long-lasting effects or functional improvements. However, PEA and decompression with the inflatable balloon catheter led to maintenance of pain relief for more than seven months and improvements in the functional status with increases in the walking distance. The present case series suggests that the inflatable balloon catheter may be an effective alternative to performing PEA when conventional methods fail to remove adhesions or sufficiently relieve stenosis.

Microvascular decompression is the gold standard for the treatment of trigeminal neuralgia (TN). However, percutaneous techniques still play a role in treating patients with TN and offer several important advantages and efficiency in obtaining immediate pain relief, which is also durable in a less invasive and safe manner. Patients' preference for a less invasive method can influence the procedure they will undergo. Neurovascular conflict is not always a prerequisite for patients with TN. In addition, recurrence and failure of the previous procedure can influence the decision to follow the treatment. Therefore, indications for percutaneous procedures for TN persist when patients experience idiopathic and episodic sharp shooting pain. In this review, we provide an overview of percutaneous procedures for TN and its outcome and complication.

Objective: We analyze pain relief, deformity correction and complication rate after percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Methods: The authors retrospectively reviewed medical records and radiological findings of 32 patients who underwent percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Results: The patients had significant pain improvement with the procedure. The visual analogue scale score reduced from 8.6 to 3.4 significantly after the procedure. The midline vertebral body height significantly increased postoperatively, but mean kyphotic angle did not. There was no serious complication except one case of epidural cement leakage without neurological impairment. Conclusion: Balloon kyphoplasty safely can reduce severe back pain and returned geriatric patients to higher activity levels. The midline vertebral height is restored significantly. However kyphotic deformity correction is not significant as contrary to what we expected from the present study before it was carried out.

Vertebral compression fractures can occur due to trauma, a malignancy, or most commonly, osteoporosis. These fractures are frequently seen in elderly women; 30% of postmenopausal women are affected by vertebral compression fractures. These fragile fractures frequently result in both acute and chronic pain, but more importantly, are a source of increased morbidity and possibly, mortality. These injuries can be treated both conservatively and with surgery. The use of percutaneous vertebral augmentation offers a minimally invasive approach for the treatment of vertebral compression fractures. We experienced two cases of compression fractures diagnosed during the treatment of thoracic postherpetic neuralgia. Two patients suffering from postherpetic neuralgia with a sharp and stabbing pain in the thoracic dermatomes that was unresponsive to conservative treatment were transferred to our clinic. During the management of postherpetic neuralgia, we incidentally found thoracic compression fractures after obtaining fluoroscopic guided images. After a balloon kyphoplasty, the preoperative pain related to the postherpetic neuralgia was successfully relieved soon after the procedure, and there were no complications.

Trigeminal neuralgia is a condition associated with severe episodic lancinating facial pain subject to remissions and relapses. Trigeminal neuralgia is often associated with blood vessel cross compression of the root entry zone or more rarely with demyelinating diseases and occasionally with direct compression by neoplasms of the posterior fossa. If initial medical management fails to control pain or is associated with unacceptable side effects, a variety of surgical procedures offer the hope for long-lasting pain relief or even cure. For patients who are healthy without significant medical co-morbidities, direct microsurgical vascular decompression [MVD] offers treatment that is often definitive. Other surgical options are effective for elderly patients not suitable for MVD. Percutaneous retrogasserian glycerol rhizotomy is a minimally invasive technique that is based on anatomic definition of the trigeminal cistern followed by injection of anhydrous glycerol to produce a weak neurolytic effect on the post-ganglionic fibers. Other percutaneous management strategies include radiofrequency rhizotomy and balloon compression. More recently, stereotactic radiosurgery has been used as a truly minimally invasive strategy. It also is anatomically based using high resolution MRI to define the retrogasserian target. Radiosurgery provides effective symptomatic relief in the vast majority of patients, especially those who have never had prior surgical procedures. For younger patients, we recommend microvascular decompression. For patients with severe exacerbations of their pain and who need rapid response to treatment, we suggest glycerol rhizotomy. For other patients, gamma knife radiosurgery represents an effective management strategy with excellent preservation of existing facial sensation.

Objective : Avascular necrosis (AVN) of the vertebral body is known as a relatively uncommon phenomenon in a vertebral compression fracture (VCF). The outstanding radiologic findings of AVN are intravertebral vacuum phenomenon with or without fluid collection. Several reports revealed that PVP or balloon kyphoplasty might be the effective treatment modalities for AVN. We also experienced excellent results when using PVP for the treatment of AVN of the vertebral body, and intend to describe the treatment's efficacy in this report. Methods : Thirty-two patients diagnosed with AVN of the vertebral body were treated with PVP. We measured the pre- and post-operative anterior body height and kyphotic angulation. The visual analogue scale (VAS) was used to determine the relief of back pain. Results : The anterior body height (pre-operative : 1.49 cm, post-operative : 2.22 cm) and kyphotic angulation (pre-operative : 14.47 degrees, post-operative : 6.57 degrees) were significantly restored (p<0.001). VAS was improved from 8.9 to 3.7. Pseudoarthrosis was corrected in all cases, which was confirmed by dynamic radiographs. Fluid collection was found in sixteen cases and was aspirated with serous nature. No organism and tumor cell were noted. Conclusion : PVP proved to be an effective procedure for the treatment of AVN of the vertebral body, which corrected dynamic instability and significantly restored the anterior body height and kyphotic angulation.
