Evaluation of the relationship between computed tomography angiography collateral scores and clinical outcome.

BACKGROUND: The relationship between collateral circulation and prognosis after endovascular treatment in anterior circulation strokes has been reported in many studies. OBJECTIVE: In this study, we aimed to compare the predictive power of clinical outcome by comparing five different collateral scores that are frequently used. METHODS: Among the patients who underwent endovascular treatment in our clinic between November 2019 and December 2021, patients with premorbid mRS < 3, intracranial ICA and/or MCA M1 occlusion, and a pre-procedural multiphase CTA examination were included in the study. Demographic, technical, and duration information about the procedure, major events after the procedure, and clinical outcomes at 3 months were recorded. The mCTA, Tan, Maas, Miteff, and rLMC collateral scores of the patients were evaluated. RESULTS: Clinical outcome at 3 months were good in 37 of the 68 patients included in the study (mRS ≤ 2). Only the mCTA and rLMC collateral scores were statistically significantly higher in those with a good clinical outcome. Significant correlation with 3-month mRS was detected only in mCTA and rLMC scores. Although rLMC and mCTA collateral scores showed a statistically significant association with prognosis, they were not sufficient to be an independent predictor of prognosis. CONCLUSION: mCTA and rLMC were found to have the highest predictive power of clinical outcome and the highest correlation with the 3-month clinical outcome. Our study suggests that it would be beneficial to develop a new scoring system over multiphase CTA, which combines regional and temporal evaluation, which are the strengths of both collateral scoring.

ANTECEDENTES: A relação entre circulação colateral e prognóstico após tratamento endovascular em acidentes vasculares cerebrais de circulação anterior tem sido relatada em muitos estudos. OBJETIVO: Neste estudo, nosso objetivo foi comparar o poder preditivo do desfecho clínico comparando cinco escores colaterais diferentes que são frequentemente utilizados. MéTODOS: Entre os pacientes submetidos a tratamento endovascular em nossa clínica entre novembro de 2019 e dezembro de 2021, foram incluídos no estudo pacientes com mRS pré-mórbido < 3, oclusão intracraniana de ICA e/ou MCA M1 e exame de CTA multifásico pré-procedimento. Foram registradas informações demográficas, técnicas e de duração sobre o procedimento, eventos importantes após o procedimento e resultados clínicos em três meses. Foram avaliados os escores colaterais mCTA, Tan, Maas, Miteff e rLMC dos pacientes. RESULTADOS: Os resultados clínicos aos três meses foram bons em 37 dos 68 pacientes incluídos no estudo (mRS ≤ 2). Apenas os escores colaterais mCTA e rLMC foram estatisticamente significativamente maiores naqueles com boa evolução clínica. Correlação significativa com mRS de três meses foi detectada apenas nos escores mCTA e rLMC. Embora os escores colaterais de rLMC e mCTA tenham mostrado uma associação estatisticamente significativa com o prognóstico, eles não foram suficientes para serem um preditor independente de prognóstico. CONCLUSãO: Verificou-se que mCTA e rLMC têm o maior poder preditivo do resultado clínico e a maior correlação com o resultado clínico de três meses. Nosso estudo sugere que seria benéfico desenvolver um novo sistema de pontuação em vez de CTA multifásico, que combinasse avaliação regional e temporal, que são os pontos fortes de ambas as pontuações colaterais.

Evaluation of the efficacy of peripheral nerve block alone in episodic and chronic migraine patients.

BACKGROUND: Peripheral nerve block (PNB) is usually performed in patients with migraine who are resistant to treatment with medications. OBJECTIVE: To compare the efficacy of PNB alone and PNB combined with prophylactic medications in migraine patients. METHOD: The data on migraine patients who underwent PNB in our clinic between November 2019 and January 2022 were retrospectively reviewed. Blocks of the greater occipital nerve (GON), lesser occipital nerve (LON) and supraorbital nerve (SON) were performed upon admission and in the second week. RESULTS: The study included 116 patients. While 21 out of 39 episodic migraine (EM) patients continued to use prophylactic medications, 18 were followed up with PNB alone. While 49 out of 77 chronic migraine (CM) patients continued to use prophylactic medications, 28 were followed up with PNB alone. Comparison of the admission and second-month data of the patients who only underwent PNB and those who continued the drug treatment together with PNB in both the EM and the CM group showed that the number of days with pain, number of analgesics taken and scores on the Visual Analog Scale (VAS) and the Migraine Disability Assessment (MIDAS) were significantly reduced in both groups (p < 0.01). Comparison of the second-month data of the patients followed up with PNB alone and those followed up with PNB together with prophylactic medications showed that there was no significant difference between the EM and CM patients (p > 0.05). CONCLUSION: Bilateral GON, LON and SON block with lidocaine injection seems to be an effective treatment on its own, without the need for prophylactic medications, in both EM and CM patients during a two-month follow-up.

ANTECEDENTES: O bloqueio de nervos periféricos (BNP) geralmente é realizado em pacientes com migrânea resistentes ao tratamento medicamentoso. OBJETIVO: Comparar a eficácia do BNP isolado e do BNP combinado com medicamentos profiláticos em pacientes com enxaqueca. MéTODO: Os dados de pacientes com enxaqueca submetidos a BNP em nossa clínica entre novembro de 2019 e janeiro de 2022 foram revisados retrospectivamente. Bloqueios do nervo occipital maior (NOM), nervo occipital menor (NOM) e nervo supraorbital (NSO) foram realizados na admissão e na segunda semana. RESULTADOS: O estudo incluiu 116 pacientes. Enquanto 21 dos 39 pacientes com enxaqueca episódica (EE) continuaram a usar medicamentos profiláticos, 18 foram acompanhados apenas com BNP. Enquanto 49 dos 77 pacientes com enxaqueca crônica (EC) continuaram a usar medicamentos profiláticos, 28 foram acompanhados apenas com BNP. A comparação dos dados de admissão e do segundo mês dos pacientes que fizeram apenas BNP e daqueles que continuaram o tratamento medicamentoso junto com BNP, tanto no grupo EE quanto no grupo EC, mostrou que o número de dias com dor, o número de analgésicos tomados e os escores da Escala Visual Analógica (EVA) e da Avaliação da Incapacidade da Enxaqueca (AIE) foram significativamente reduzidos em ambos os grupos (p < 0,01). A comparação dos dados do segundo mês dos pacientes acompanhados apenas com BNP e aqueles acompanhados com BNP juntamente com medicações profiláticas mostrou que não houve diferença significativa entre os pacientes EE e EC (p > 0,05). CONCLUSãO: O bloqueio bilateral de NOM, NOM e NSO com injeção de lidocaína parece ser um tratamento eficaz por si só, sem a necessidade de medicamentos profiláticos, tanto em pacientes EE quanto com EC durante um seguimento de dois meses.

Effectiveness of peripheral nerve blockage on the symptoms of both diseases in patients with fibromyalgia and chronic migraine coexistence.

OBJECTIVE: Peripheral nerve blockage treatments reduce central sensitization and are effective in patients with migraine. We wanted to evaluate the efficacy of peripheral nerve blockage in patients with fibromyalgia and migraine whose etiology may be responsible for central sensitization, and their associations are common. METHODS: The files of patients with chronic migraine who had peripheral nerve blockage treatment in our clinic and had fibromyalgia were scanned. The patients underwent bilateral great occipital nerve, lesser occipital nerve, and supraorbital nerve blockage at baseline and in the second week. The revised Fibromyalgia Impact Questionnaire, Migraine Disability Assessment Scale, Visual Analog Scale scores, the number of days in pain, and the number of analgesics taken in the last month were recorded. RESULTS: In the third month, Fibromyalgia Impact Questionnaire, Migraine Disability Assessment Scale, and Visual Analog Scale scores were significantly lower from baseline. While Fibromyalgia Impact Questionnaire scores in the third month were significantly lower than in the first month, no significant difference was observed between Visual Analog Scale scores. In the third month, the number of days in pain and the number of analgesics taken in the last month was significantly lower than the baseline but higher than the first month. CONCLUSION: Peripheral nerve blockage has been found to be an effective treatment for the symptoms of both diseases in patients with migraine and fibromyalgia coexistence.
