ABSTRACT
Abstract INTRODUCTION: Left atrial ganglionated plexi ablation is an adjuvant technique used to increase the success rate of surgical ablation of atrial fibrillation. Ganglionated plexi ablation requires previous detection. We aimed to assess determinants of successful ganglionated plexi detection and to correlate range of ganglionated plexi ablation with risk of early atrial fibrillation recurrence. METHODS: The study involved 34 consecutive patients referred for surgical coronary revascularization with concomitant atrial fibrillation ablation. Ganglionated plexi detection was done by inducing vagal reflexes in the area of the pulmonary veins and left atrial fat pads. RESULTS: Detection of GP was successful in 85% of the patients. There was no difference in preoperative characteristics nor in atrial fibrillation type between patients in whom ganglionated plexi detection was successful and others. The number of detected ganglionated plexi correlated significantly only with preoperative resting heart rate. Significant negative correlation was found in patients with preoperative heart rate>75 beat/min in terms of total number of detected ganglionated plexi (P=0.04). Average number of detected ganglionated plexi was significantly higher in patients with in-hospital atrial fibrillation recurrence requiring electrical cardioversion (3.8±3) in comparison to rest of the study population (2±1.3; P=0.02). In patients in whom 4 or more ganglionated plexi were detected, significantly increased risk of in-hospital atrial fibrillation recurrence was observed (OR 15; 95% CI 1.5-164; P=0.003). CONCLUSION: Left atrial ganglionated plexi detection was unsuccessful in a considerable percentage of patients. Preoperative heart rate significantly influenced positive ganglionated plexi detection and number of ablated ganglia. Higher number of detected ganglionated plexi was related with early recurrence of atrial fibrillation.

PURPOSE: To investigate the effects of dorsal root ganglion destruction in patients with postherpetic neuralgia (PHN). METHODS: Seventy-two patients with PHN selected were randomly divided into two groups (n=36). Group A was the control group (treated by injection) and group B was the group of dorsal root ganglion destruction by adriamycin. Visual analog scale scores (VAS), SAS, SF-MPQ scores. Clinical effects and therapy safety were evaluated before therapy, one week, three and six months after therapy. Forty-four patients were available for intention-to-treat analysis. RESULTS: The average pain scores on the Likert scale were significantly reduced at each point in group B. Patients in group B reported clinical effectiveness at six months as excellent response, good response, improved but unsatisfactory or unchanged 16, 12 and 8.VAS scores at each time point after the operation were lower than that before operation and in group A, there was significant difference. Patients showed significant improvement in sleep scores in group B. There was significant difference at T2 in group A than T1. There was no significant difference in group A at T3, T4 after the operation than that before operation. Between group comparison: there was significant difference between group A and group B at each time point after the operation. CONCLUSIONS: Dorsal root ganglion destruction by adriamycin under guidance of C-arm perspective, the puncture operation was accurate without any adverse reaction or serious complications, which could effectively relieve pain of patients with postherpetic neuralgia, but the long-term effects needed further study.
OBJETIVO: Investigar os efeitos da destruição da raiz dorsal ganglionar em pacientes com neuralgia pós-herpética. MÉTODOS: Setenta e dois pacientes selecionados com neuralgia pós-herpética foram randomicamente distribuídos em dois grupos (n=36). Grupo A foi o grupo controle (tratado por injeção) e o grupo B foi o grupo com destruição da raiz dorsal do gânglio pela adriamicina. Os escores da Escala Analógica Visual (VAS), SAS, SF-MPQ escores, efeitos clínicos e segurança terapêutica foram avaliados as antes da terapia, uma semana, três e seis meses após a terapia. Quarenta e quatro pacientes foram avaliados pela análise de intenção-em-tratar. RESULTADOS: A média dos escores de dor na escala de Likert foi significativamente reduzida em cada ponto no grupo B. Pacientes no grupo B relataram efetividade clínica aos seis meses com excelente resposta (16), boa resposta (12), melhora mais insatisfatória ou sem modificações (8). Escores VAS a cada tempo após o procedimento foram melhores em comparação ao pré-operatório. No grupo A não foi observada diferença significativa. Pacientes mostraram melhora nos escores de dormir no grupo B. Houve diferença significante no T2 no grupo A que T1. Não houve diferença significante no grupo A nos tempos T3 e T4 após a cirurgia em relação a antes. Comparação entre os grupos: houve diferença significante entre os grupos A e B a cada tempo após a cirurgia. CONCLUSÕES: A destruição da raiz dorsal ganglionar pela adriamicina sob perspectiva guiada pelo C-arm, a cirurgia pontual foi acurada sem qualquer reação adversa ou complicação séria, que pode efetivamente aliviar a dor em pacientes com neuralgia pós-herpética, mas os efeitos de longo prazo necessitam mais estudos.

This study investigates the role of cervical sympathectomy in the prevention of acute vasospasm induced by meningeal haemorrhage in rabbits. Sixteen adult English Norfolk rabbits were divided into 2 experimental groups: bilateral cervical sympathectomy of the superior sympathetic ganglion (SSSG, n=8), and bilateral SSSG and sympathectomy of the inferior sympathetic ganglion (SISG, n=8). Other 24 animals were used as controls. Basilar artery diameter was evaluated by angiography. SSSG protected the animals against developing cerebral vasospasm; SSSG associated with SISG did not increase this effect.
Este estudo investiga o papel da simpatectomia cervical na prevenção do vasoespasmo agudo induzido por hemorragia meníngea em coelhos. Para tanto, foram utilizados 16 coelhos adultos da raça Norfolk inglesa, divididos em 2 grupos experimentais: simpatectomia cervical bilateral do gânglio simpático cervical superior (SSSG, n=8) e SSSG associada a simpatectomia cervical bilateral do gânglio simpático cervical inferior (SISG, n=8). Outros 24 animais foram usados como controles. Os diâmetros das artérias basilares foram avaliados por medições após angiografias. SSSG protegeu os animais contra o vasoespasmo; SSSG associada a SISG não aumentou este efeito.

The aim of the present study has been to examine the effects of superior cervical ganglionectomy (SCGx) on the hypertrophic (thyroid lobe weight) and hyperplastic (thyroid mitotic activity) response of the rat thyroid gland in basal conditions or after hemithyroidectomy (hemiTx), both being assessed 14 days after the surgeries. It has been shown that: 1) Ipsilateral and./or bilateral SCGx brought about the growth (both hypertrophy and hyperplasia) of thyroid lobes in the animals with intact thyroid; the strongest hypertrophic reaction occurred after ipsilateral SCGx and the strongest hyperplastic response followed bilateral SCGx. 2) Unilateral SCGx, when performed ipsilaterally to the remaining thyroid lobe after hemiTx amplified the hypertrophic, but no hyperplastic response of this lobe. Both contralateral and bilateral SCGx had no effect on the hypertrophy of the remaining thyroid lobe. Unexpectedly, both bilateral and contralateral SCGx exerted the suppressive effect on the hyperplastic response of the thyroid lobe following hemiTx. These results indicate that the sympathetic innervation plays an important role in the control of thyroid growth of intact animals and/or after hemiTx
