Trigeminal neuralgia (TGN) is a very peculiar disease, mostly characterized by unilateral paroxysmal facial pain, often described by patient as ‘one of the worst pain in my life’. This condition is also known as ‘Tic Douloureus’. The annual incidence of TN is about 4.7/100000 population, male and female are equally affected. The diagnosis is usually made by history, clinical fi ndings and cranial imaging is required to rule out compressing vascular loop, organic lesions and Multiple Sclerosis (MS) at Trigeminal nerve (TN). Treatment of TGN ranged from medical to surgical intervention. Between September 2007 and April 2015, 20 patients underwent micro vascular decompression (MVD) of TN for TGN who were refractory to medical treatment at department of Neurosurgery, Bir Hospital. All decompressions were performed using operating microscope. Follow up period ranged from 22 months to 8 years.There were 9 males and 11 females and age ranged from 30-70 years. The neuralgic pain was localized on right side in 13 patients and left on 7 patients. Pain distribution was on V3 (mandibular branch) dermatome in 11, V2( Maxillary branch ) in 4, V2-3 in 2 and V1- 2-3 in 3 patients respectively. On intraoperative fi ndings TN was compressed by superior cerebellar artery ( SCA ) in 8, tumors in 4, unidentifi ed vessels in 3, veins in 2, anterior inferior cerebellar artery ( AICA ) in 1 and no cause was found in 2 patients. 7 patients suffered postoperative complications which included hyposthesia in 3, pseudomeningocele in 3 and meningitis in 1. There was no mortality in this series. 20 patients felt pain relief immediately after procedure and 1 patients came after 3 years with recurrent pain requiring second surgery. In conclusion, MVD for TGN in younger patients who are refractory to medical treatment is one of the best treatment options which is safe and long term pain relief is achieved in majority of cases.Nepal Journal of Neuroscience, Vol. 14, No. 2,  2017 Page:11-15

Long Term Follow Up

Background: Hemodynamic flow is one of the major factors in the progression and rupture of intracranial aneurysms (IA). Flow diverter devices (FD) reduce blood flow in the aneurysm sac, allow gradual stagnation, thrombosis and neointimal remodeling while maintain outflow in the side branches and perforators. Objectives: We present our experience and long-term follow-up on endovascular reconstruction of complexes IA using flow diverter device. Particularly we analyze our experience with (Pipeline endovascular device) PED. Methods: Since March 2006 to July 2015, 1000 patients (pt) with IA were treated with FD or FD/coils. Of this group 633 pt were with PED, 113 Surpass (SNEG), 111 P64, 78 Cardiatis, 40 WEB and others 25. Angiographic follow-up was performed at 3, 6, 12 months and yearly until 8 y Fup. An inclusion criteria was unfavorable anatomy for coil, dome to neck ratio ≥ 2, Neck ≥ 4 mm and recurrence following previous treatment. Results: We treated 633 Pt with 704 IA with 932 PED. (77 % female); mean age 55 y (range 7-88). History of SAH was present in 18,5%; 81,5% were unruptured IA; mass effect in 125 pt; incidental IA 96 pts; headache 77 pts, others 23 pts. Large/giant IA were present in 51,2%, and wide neck (>4mm) 65%. The technical success was 98,4%. Occlusion rate at 1yr was 90 % and 8 yr 100 %, without recurrences. Peri-procedural (30 days) morbi-mortality rate was 5.9%: 2.7% had definitive neurologic defects; death rate was 3.2%. Conclusion: Endovascular treatment of complex IA with FD is a safe, effective and stable procedure, with an acceptable morbi-mortality rate.

Abstract Background: Microvascular decompression is an accepted, safe, and useful surgical technique for the treatment of trigeminal neuralgia. Autologous muscle or implant materials such as shredded Teflon are used to separate the vessel from the nerve but may occasionally be inadequate, become displaced or create adhesions and recurrent pain. Objective: The authors evaluated the use of arachnoid membrane of the cerebellopontine angle to maintain the transposition of vessels from the trigeminal nerve. Methods: The authors conducted a retrospective review of microvascular decompression operations in which the offending vessel was transposed and then retained by the arachnoid membrane of the cerebellopontine cistern, specifically by the lateral pontomesenchepalic membrane. Results: This technique was used in 30 patients of the most recently operated series. Postoperatively, complete pain relief was achieved in 90% of the patients without any observed surgical complications. Conclusion: To the authors’ knowledge this is the first report in which the arachnoid membrane is used in the microvascular decompression of the trigeminal nerve. While this technique can be used only for selected cases, the majority of the vascular compressions on the trigeminal nerve are due to the SCA, so this sling transposition technique can be useful and effective.

Abstract Background and Objective Trigeminal neuralgia is a common neurologic disease that seriously impacts a patient's quality of life. We retrospectively investigated the efficacy and safety of internal neurolysis (nerve combing) for trigeminal neuralgia without vascular compression. Patients and Methods This study was a retrospective review of all patients with trigeminal neuralgia who were admitted between January 2014 and February 2019. A subgroup of 36 patients had no vascular compression at surgery and underwent internal neurolysis. Chart review and postoperative follow-up were performed to assess the overall outcomes of internal neurolysis. Results Thirty-six patients were identified, with a mean age of 44.89 ± 7.90 (rang: 31–65) years and a disease duration of 5.19 ± 2.61 years. The immediate postoperative pain relief (Barrow Neurological Institute [BNI] pain score of I or II) rate was 100%. The medium- to long-term pain relief rate was 91.7%. Three patients experienced recurrence. Facial numbness was the primary postoperative complication. Four patients with a score of III on the BNI numbness scale immediately after surgery had marked improvement at 6 months. No serious complications occurred. Conclusion Internal neurolysis is a safe and effective treatment for trigeminal neuralgia without vascular compression or clear responsible vessels.

Abstract INTRODUCTION Trigeminal neuralgia has always been a disease of conflict from pathological and management perspectives. Despite advances in the radiological imaging, evidence from autopsy studies, and intraoperative findings, concrete answers are not in sight. GKRS has been a strong contender among available treatment options for the management of trigeminal neuralgia. METHODS All patients were evaluated on clinical criteria, BNI scale for intensity of pain, and facial hypoesthesia (if any) in a protocol-based manner. Only patients with BNI III to V were offered GKRS as a treatment modality. The Marseille point was targeted with a 70 to 90 Gy dose at 50% isodose. Patients were informed about all available treatment options with long-term prognosis and pain control rates. Patients in need of an immediate pain relief, in failed GKRS, and in a severe pain jeopardizing routine life and eating habits were not offered GKRS and were managed with microvascular decompression. RESULTS A total of 108 (65 males, 43 females) patients received GKRS with the Perfexion model since 2009. Eighty-two percent of the patients received GKRS for primary trigeminal neuralgia, while the rest received GKRS for secondary trigeminal neuralgia due to skull base lesions (meningioma, schwannoma, cerebellar AVM, etc). A total of 78% of the patients had preoperative BNI scale IV, while 19% and 3% of the patients had grade III and V scale pain, respectively. Ninety-four percent patients gained BNI scale III intensity pain within 3 mo of GKRS. The 3-yr pain control rate (BNI I-II) could be attained in 81% of the patients. Twelve percent of the patients remained in BNI grade III. Two patients needed redo GKRS for their pain recurrence. CONCLUSION It remains uncontested that MVD provides the best long-term pain-free control in patients of trigeminal neuralgia; however, GKRS remains a valuable feasible option for a selected group of patients. GKRS should be offered as an alternative treatment modality in patients not in urgent need of pain relief. In failed GKRS, authors did not encounter any difficulty in microvascular decompression.

Object. Microvascular decompression (MVD) has become one of the primary treatments for typical trigeminal neuralgia (TN). Not all patients with facial pain, however, suffer from the typical form of this disease; many patients who present for surgical intervention actually have atypical TN. The authors compare the results of MVD performed for typical and atypical TN at their institution. Methods. The results of 2675 MVDs in 2264 patients were reviewed using information obtained from the department database. The authors examined immediate postoperative relief in 2003 patients with typical and 672 with atypical TN, and long-term follow-up results in patients for whom more than 5 years of follow-up data were available (969 with typical and 219 with atypical TN). Outcomes were divided into three categories: excellent, pain relief without medication; good, mild or intermittent pain controlled with low-dose medication; and poor, no or poor pain relief with large amounts of medication. The results for typical and atypical TN were compared and patient history and pain characteristics were evaluated for possible predictive factors. Conclusions. In this study, MVD for typical TN resulted in complete postoperative pain relief in 80% of patients, compared with 47% with complete relief in those with atypical TN. Significant pain relief was achieved after 97% of MVDs in patients with typical TN and after 87% of these procedures for atypical TN. When patients were followed for more than 5 years, the long-term pain relief after MVD for those with typical TN was excellent in 73% and good in an additional 7%, for an overall significant pain relief in 80% of patients. In contrast, following MVD for atypical TN, the long-term results were excellent in only 35% of cases and good in an additional 16%, for overall significant pain relief in only 51%. Memorable onset and trigger points were predictive of better postoperative pain relief in both atypical and typical TN. Preoperative sensory loss was a negative predictor for good long-term results following MVD for atypical TN.

The Pipeline Embolization Device (PED) was approved for the treatment of intracranial aneurysms from the petrous to the superior hypophyseal segment of the internal carotid artery. However, since its approval, its use for treatment of intracranial aneurysms in other locations and non-sidewall aneurysms has grown tremendously. The authors report on a cohort of 15 patients with 16 cerebral aneurysms that incorporated an end vessel with no significant distal collaterals, which were treated with the PED. The cohort includes 7 posterior communicating artery aneurysms, 5 ophthalmic artery aneurysms, 1 superior cerebellar artery aneurysm, 1 anterior inferior cerebellar artery aneurysm, and 2 middle cerebral artery aneurysms. None of the aneurysms achieved significant occlusion at the last follow-up evaluation (mean 24 months). Based on these observations, the authors do not recommend the use of flow diverters for the treatment of this subset of cerebral aneurysms.

Abstract Trigeminal neuralgia (TN) due to vertebrobasilar dolichoectasia (VBD) is a rare disease that can be challenging to treat. The objectives of this study are to investigate the characteristics of patients with TN due to VBD and to analyze the efficacy of microvascular decompression (MVD) by the interposition method for treatment of the condition. From 2010 till 2020, the data of 30 patients with TN due to VBD who were treated with MVD by the interposition method were analyzed retrospectively. The characteristics of the patients were compared with those of patients with non-VBD TN (n = 815). Kaplan–Meier survival analysis was performed to determine pain-free survival. The 30 patients (21 males, 9 females; mean age, 63.03 years) accounted for 3.55% of all patients with TN during the study period. In 30 patients, the offending vessel was the basilar artery (BA) in 1 patient, the vertebral artery (VA) in 6 patients, the VA plus the superior cerebellar artery (SCA) in 6 patients, the VA plus the anterior inferior cerebellar artery (AICA) in 12 patients, and the VA+SCA+AICA in 5 patients. Compared to non-VBD TN patients, those with TN due to VBD were significantly more likely to be male, to have TN of the left side, and to have hypertension (all P < 0.001). Mean age at surgery (P = 0.057) and symptom duration (P = 0.308) were comparable between the two groups. All 30 patients had immediate relief of facial pain after MVD and could stop medication. There were no postoperative complications. Over mean follow-up of 76.67 months, 3 patients had recurrence. The mean duration of pain-free survival was 70.77 months. In conclusions, TN due to VBD appears to be more likely in males, in those with hypertension, and to involve the left side. The interposition method performed by experienced and skilled neurosurgeons is a safe and effective treatment for TN due to VBD. Further studies are needed to analyze the associated long-term results and the pain recurrence rate among this special population.

Idiopathic Trigeminal Neuralgia

Abstract Background. We aimed to present the immediate and long term effect of percutaneous balloon compression (PBC) for idiopathic trigeminal neuralgia (ITN). Methods. ITN patients who underwent PBC for the first time in the past seven years were enrolled. Base line data and immediate postoperative outcomes were collected by reviewing the medical records and long term results. Kaplan-Meier curve, life-table analysis proportional-hazards analysis were utilized to assess the long term results and the likelihood of tic recurrence. Results. 12,797 patients were enrolled. Immediate after the PBC procedure, complete and partial pain relief were achieved in 95.6% and 1.1% patients respectively, with no relief in 1.7 % patients; the common side effects on the affected side of face included the sense loss in 98.9% patients, with 3.8% of them experienced sense loss combined abnormal sense; masseter weakness in 90.6%, herpes eruption in 51.4%, corneal reflex weakness or loss in 12.7% patients. The fewer perioperative complications covered diplopia in 139 patients (1.1%), partial hearing loss in 190 patients (1.5%), vascular complications in 5 patients (0.05%), brainstem hematoma in one patient (0.01%), ischemic stroke in two patients (0.02%), intracranial hemorrhage in 11 patents (0.09%), and intracranial infection in one patient (0.01%) patients. Of three deaths happened in the perioperative period, two died of intracranial hemorrhage, and the other one died of intracranial infection. 5794 (49.2%) patients, who were followed than one year after the procedure, were included in the follow-up study, with the median follow-up period of 7.2 years. Complete and partial pain relief were obtained in 82.9% and 6.8% patients respectively, while the pain recurrence occurred in 8.5% patients. Side effects included sense loss without abnormal sense in 54.3%, with acceptable abnormal sense in 6.0%, and with severe abnormal sense in 2.0% patients. Masseter weakness was reported by 7.5% patients. 96.4% patients were satisfied with the procedure. Conclusion. Our study shows PBC is a safe, simple and effective procedure, with both immediate and long-term success rates, acceptable side effects and fewer deadly complications, should be considered as one of the best choice for the treatment of ITN patients.

OBJECTIVE Gamma Knife radiosurgery (GKRS) is an established surgical option for the treatment of trigeminal neuralgia (TN), particularly for high-risk surgical candidates and those with recurrent pain. However, outcomes after three or more GKRS treatments have rarely been reported. Herein, the authors reviewed outcomes among patients who had undergone three or more GKRS procedures for recurrent TN. METHODS The authors conducted a multicenter retrospective analysis of patients who had undergone at least three GKRS treatments for TN between July 1997 and April 2019 at two different institutions. Clinical characteristics, radiosurgical dosimetry and technique, pain outcomes, and complications were reviewed. Pain outcomes were scored on the Barrow Neurological Institute (BNI) scale, including time to pain relief (BNI score ≤ III) and recurrence (BNI score > III). RESULTS A total of 30 patients were identified, including 16 women and 14 men. Median pain duration prior to the first GKRS treatment was 10 years. Three patients (10%) had multiple sclerosis. Time to pain relief was longer after the third treatment (p = 0.0003), whereas time to pain recurrence was similar across each of the successive treatments (p = 0.842). Complete or partial pain relief was achieved in 93.1% of patients after the third treatment. The maximum pain relief achieved after the third treatment was significantly better among patients with no prior percutaneous procedures (p = 0.0111) and patients with shorter durations of pain before initiation of GKRS therapy (p = 0.0449). New or progressive facial sensory dysfunction occurred in 29% of patients after the third GKRS treatment and was reported as bothersome in 14%. One patient developed facial twitching, while another experienced persistent lacrimation. No statistically significant predictors of adverse effects following the third treatment were found. Over a median of 39 months of follow-up, 77% of patients maintained complete or partial pain relief. Three patients underwent a fourth GKRS treatment, including one who ultimately received five treatments; all of them reported sustained pain relief at the extended follow-up. CONCLUSIONS The authors describe the largest series to date of patients undergoing three or more GKRS treatments for refractory TN. A third treatment may produce outcomes similar to those of the first two treatments in terms of long-term pain relief, recurrence, and adverse effects.

We evaluated the usefulness of endovascular treatment of posterior circulation aneurysms with GDCs and IDCs, Five cases were treated with IDCs, and 15 cases were treated with GDCs. In this study, 8 aneurysms were identified at the basilar bifurcation, 3 at the P1 segment of the pasterior cerebral artery, 1 at the origin of the superior cerebellar artery, 2 at the vertebrobasilar junction, 1 at the origin of the posterior inferior cerebellar artery, 1 at the distal anterior inferior cerebellar artery, and 4 dissecting aneurysms at the vertebral artery. Thirteen of the aneurysms were small (< 12 mm), 5 were large (13–24 mm), and 2 were giant (> 25 mm). Of the 20 patients, 14 patients returned to their previous occupation. Patients with permanent deficits included 2 patients with infarction caused by thromboembolic complications during the embolization procedure, and 2 with infarction caused by vasospasm. There were 2 deaths. The outcomes of the patients seemed favorable. However, long-term follow-up is necessary to determine the usefulness of detachable coils.
