Supraorbital Nerve

Hemicrania continua (HC) is an uncommon primary headache disorder in which the diagnosis centers on unilaterality and its absolute responsiveness to indomethacin. We describe 3 patients with a long standing history of headache diagnosed as hemicrania continua. There was profound response to indomethacin which was limited by side effects. In one patient the therapy with indomethacin was limited secondary to comorbidities. Initial diagnostic blockade provided significant relief of symptoms based on which radio-frequency ablation of the supraorbital nerve was performed with substantial improvement in symptoms. Traditionally, hemicrania continua has been managed exclusively with oral analgesics and is defined by its singular response to indomethacin. Radio-frequency ablation (RFA) has been reported in the literature for multiple indications. This case series is unique in that it describes 3 patients diagnosed with hemicrania continua with pain referred in the supraorbital nerve distribution, who underwent radiofrequency ablation of the supraorbital nerve with resultant resolution of headaches. Traditionally, hemicrania continua has been managed exclusively with oral analgesics and is defined by its singular response to indomethacin. This report is unique in that it describes three patients diagnosed with hemicrania continua with pain referred in the supraorbital nerve distribution who underwent radiofrequency ablation of the supraorbital nerve with resultant resolution of headaches. After the RFA medical management was minimal to none in both patients. Though the utility and cost efficacy of RFA of peripheral nerves needs to be confirmed in well-designed trials we present these cases as an example of how this minimally invasive technique can safely provide analgesia in a difficult to treat cephalgia. Moreover if precise anatomical localization of the headache is possible then diagnostic blockade of the appropriate peripheral nerve may be performed followed by radiofrequency ablation to provide potentially more sustained analgesia in patients where medical management is ineffective or poorly tolerated.

AbstractKnee osteoarthritis (OA) is a common condition associated with pain and physical impairment in a large segment of the population. The traditional treatment algorithm progresses from conservative modalities to nonsurgical options to surgical intervention. Surgical intervention often provides reliable pain relief but not all patients are surgical candidates and there are some patients who prefer not to have surgery. Cooled radio frequency ablation (C-RFA) is a treatment with the potential to provide pain relief for patients who no longer benefit from noninvasive modalities and who desire an alternative to surgery. The objective of this review article is to provide the rationale, available evidence, indications, and outcomes associated with C-RFA for the treatment of chronic knee OA. A total of eight reports that use C-RFA in the treatment of chronic knee pain were identified and analyzed. There were two prospective trials, one retrospective cohort study, and five case reports or case series. C-RFA is an emerging procedure with encouraging early results; however, additional long-term prospective clinical trials are necessary to further characterize how C-RFA can best be used to treat chronic knee pain.

Accessory Pathways

Background Radiofrequency ablation has been established as the curative treatment for most of supraventricular tachycardia since 1987. In SGNHC, ablation has been done routinely since 2003. In our experience, right sided accessory pathway (AP) has been technically difficult and challenging with low success rate as mentioned in literature outside. So, the objective of this article was to analyze the demographic characteristics, success and recurrence rate and complication of right sided AP ablation in our centre. Methods and Materials From 13th Oct 2003 to 9th Sept. 2011, altogether 768 patients who underwent ablation were analyzed. Result Among 768 patients, 416(54.2%) were accessory pathways out of which 72(17.3%) were right sided AP. Majority of right sided accessory pathway were manifest (WPW) comprising 77.1%, significantly higher compare to left sided pathway where manifest AP was only 44.1 % (p< 0.001). Among all attempted ablation of right sided AP, 11 ablations failed so that the success rate was 84.7% lower than that of left sided pathway where success rate was 98.4% (p<0.001). Among 61 successful ablations, 2 relapsed during follow up period, recurrence rate being 3.3%. Although there were few complications in the ablation of other tachyarrhythmia, there was no complication noted during the ablation of 72 right sided AP. Conclusion Right sided pathway are mostly manifest. The success rate of right sided pathway is lower in comparison to left sided pathway. Our success rate is comparable to the result in the literature which indicates that ablation of right sided accessory pathway in our centre is reasonably good.

Renal Masses

Background: Small renal masses are increasingly being discoveredincidentally on imaging performed for another reason. Thestandard of care for these masses involves excision by open orlaparoscopic techniques. Recently, ablative techniques such asradiofrequency ablation (RFA) and cryoablation have taken a moreprominent role in the treatment algorithm for these masses. Wesought to evaluate the efficacy and safety of radiofrequency ablationin the treatment of renal tumours.Methods: We conducted a review of the literature. There was nolanguage restriction. We obtained studies from the followingsources: the Cochrane Library, PubMed, EMBASE, LILACS andCurrent Controlled Trials.Results: We identified no clinical trials in the literature. Thus wedescribed the results from case series and retrospective studieswith a reasonable sample size (number of reported patients in eachstudy > 65). Most patients undergoing RFA had T1a disease witha mean tumour size of about 3 cm. Radiofrequency ablation wasusually performed percutaneously with image guidance. Reportedfollow-up was short and ranged from 1 to 30 months. Most seriesused radiographic response as a surrogate for cancer control. Therates of local recurrence of the tumour were as high as 13.0%(average 8.5%) and were slightly higher than those associated withcryoablation and partial nephrectomy. Complications includedhemorrhage, ureteral strictures and loss of a renal unit.Conclusion: Our review demonstrates that RFA is a suitable andpromising therapy in patients with small renal tumours who areconsidered to be poor candidates for more involved surgery.However, clinical trials with long-term data are needed to establishthe oncological efficacy.Contexte : De petites masses rénales sont de plus en plus souventdécouvertes de façon fortuite lors d’épreuves d’imagerie commandéespour une autre raison. Les soins standard pour ces massesincluent une excision par chirurgie ouverte ou par laparoscopie.Dernièrement, des techniques comme l’ablation par radiofréquence(ARF) et la cryoablation ont pris plus d’importance dans l’algorithmede traitement. Nous examinons l’efficacité et l’innocuité del’ablation par radiofréquence dans le traitement des tumeurs rénales.Méthodologie : Une revue de la littérature a été effectuée, sansrestriction de langue. Des articles ont été obtenus des sources suivantes: la Bibliothèque Cochrane, PUBMED, EMBASE, LILACS etCurrent Controlled Trials.Résultats : Comme aucun essai clinique n’a pu être cerné dans cesbases de données, nous décrivons les résultats d’études de cas etd’analyses rétrospectives avec populations de taille raisonnable(nombre de patients pour chaque étude > 65). La vaste majoritédes patients ayant subi une ARF présentaient une tumeur T1a detaille moyenne d’environ 3 cm. L’ARF était habituellement effectuéepar voie percutanée et guidée par imagerie. Le suivi était court,allant de 1 à 30 mois. La plupart des études sérielles avaient recoursà la réponse radiographique comme paramètre de substitutionde la maîtrise du cancer. Les taux de récidive locale de la tumeuratteignaient 13.0 % (moyenne 8.5%), et étaient en général légèrementplus élevés que les taux notés avec la cryoablation et lanéphrectomie partielle. Les complications signalées étaient les suivantes: hémorragie, sténose urétérale et perte d’une unité rénale.Conclusion : Le présent article montre que l’ARF est une techniqueconvenable et prometteuse chez les patients porteurs depetites tumeurs rénales considérés comme de mauvais candidatspour une intervention plus lourde. Cependant, il est impératifd’effectuer des essais cliniques à long terme afin d’établir dans unavenir rapproché l’efficacité oncologique de cette technique.

AbstractRadiofrequency Ablation of subcapsular lesions poses a challenge due to the risks of tumour seeding along the track, hemorrhage and lower efficacy. “No touch ablation” is a relatively novel technique used in the ablation of subcapsular HCC with good results. This technique avoids direct puncture of the tumour by inserting more than one electrodes adjacent to and outside the tumor and activating them sequentially to perform ablation. The risk of track site seeding and haemorrhage is significantly reduced. We describe a case of a subcapsular HCC in a 65-year-old female patient which was successfully treated with this novel technique.

Abstract Introduction: Radiofrequency ablation (RF) is a minimally invasive technique probed as effective and safe treatment alternative for the manage, We describe the results of efficacy and safety up to 12 months following the first thyroid nodules with ablative radiofrequency in Colombia.Objective: Evaluate the efficacy and safety of RF thyroid radiofrequency ablation for benign thyroid nodules in a protocol in our center in Bogotá Colombia, case series. Methodology: Prospective, observational and descriptive Trial Patients and procedure: From May/2017 to Nov/2019 we Treated 38 patients with 59 mainly solid nodules were treated with a Radiofrequency Ablation system with cooling 2 standard techniques (Trans-isthmic approach and moving Shut technique). Starmed system with cool type antenna of 16 G. and 10 mm active tip (3 cases) and Cosman RF cooled with 15 cm long active tips 5 to 15 mm 18 G electro Teflon. (35 cases). Here the first 59 nodules who completed a clinical and ultrasound follow-up to 12 months. Outcomes: initial volume was 15.4 +/-28 cc (0.03 a 203 cc) After radiofrequency ablation, the volume decreased significantly, in VRR%**. 40%, 55%, 62% y 68% at 1,3,6 & 12 months. final volume was 4.46 cc P= 0.000*. Compressive Symptoms drop from 5.84 to 1.19, 0.17, 1.76 at 1,3 & 6 moths p &lt;0.001, Cosmetic Symptoms from 2.02/4 to 0.73, 0.58, 0.41 at 1,3 & 6 moths p &lt;0.01. and Quality of Life symptoms from 0 to 10 drop from 5.6 to 2.4, 1.27 & 1.53 at 1,3 & 6 moths p&lt;0.001. Not even one serious adverse event happened. Non-serious adverse events that did happened include minimal skin ecchymosis and transitory pain during less than 3 days, average 4/10 VAS (Visual Analog Scale). None developed hypothyroidism or required hospitalization. one patient presents transitory Horner syndrome and other nodule rupture. Two patients present a transitory dysphonia. Conclusions Radiofrequency ablation performed in our institution is effective and safe for the treatment of thyroid nodules. With patient satisfaction, improve the compressive, cosmetic symptoms and quality of life and without severe complications. It is necessary to continue to enrich this experience, because reducing volume and solving compressive and cosmetic problems, is ambulatory procedure.

Spinal Epidural

Object Delayed or inappropriate treatment of spinal epidural abscess (SEA) can lead to serious morbidity or death. It is a rare event with significant variation in its causes, anatomical locations, and rate of progression. Traditionally the treatment of choice has involved emergency surgical evacuation and a prolonged course of antibiotics tailored to the offending pathogen. Recent publications have advocated antibiotic treatment without surgical decompression in select patient populations. Clearly defining those patients who can be safely treated in this manner remains in evolution. The authors review the current literature concerning the treatment and outcome of SEA to make recommendations concerning what population can be safely triaged to nonoperative management and the optimal timing of surgery. Methods A PubMed database search was performed using a combination of search terms and Medical Subject Headings, to identify clinical studies reporting on the treatment and outcome of SEA. Results The literature review revealed 28 original case series containing at least 30 patients and reporting on treatment and outcome. All cohorts were deemed Class III evidence, and in all but two the data were obtained retrospectively. Based on the conclusions of these studies along with selected smaller studies and review articles, the authors present an evidence-based algorithm for selecting patients who may be safe candidates for nonoperative management. Conclusions Patients who are unable to undergo an operation, have a complete spinal cord injury more than 48 hours with low clinical or radiographic concern for an ascending lesion, or who are neurologically stable and lack risk factors for failure of medical management may be initially treated with antibiotics alone and close clinical monitoring. If initial medical management is to be undertaken the patient should be made aware that delayed neurological deterioration may not fully resolve even after prompt surgical treatment. Patients deemed good surgical candidates should receive their operation as soon as possible because the rate of clinical deterioration with SEA is notoriously unpredictable. Although patients tend to recover from neurological deficits after treatment of SEA, the time point when a neurological injury becomes irreversible is unknown, supporting emergency surgery in those patients with acute findings.

Introduction The trigeminal autonomic cephalalgias (TACs) subsume four primary headache disorders. Hemicrania continua is increasingly regarded as an additional TAC. In rare cases patients may present with two different TACs or a TAC and hemicrania continua. Cases We report four patients with two different TACs or one TAC and hemicrania continua. Two patients presented with cluster headache and paroxysmal hemicrania, one patient with cluster headache and hemicrania continua, and one patient suffered from cluster headache and SUNCT. Discussion While the International Classification of Headache Disorders (ICHD-II) proposes specific diagnostic criteria, the variability of clinical presentation may make clear diagnosis difficult. All patients fulfilled the ICHD-II criteria. The manifestation of two different TACs or hemicrania continua in one patient is uncommon but possible and should be taken into account especially when chronic headache patients present with changing headache symptoms.
