RESUMO
Introduction: Incessant Ventricular Tachycardia is a condition characterized by multiple episodes of Ventricular Tachycardia (VT) in 24 hours, persisting despite efforts to stop the arrhythmia. In this condition, sympathectomy as the surgical procedure is considered a permanent intervention and the last resort when medications prove ineffective. This procedure comprises the cutting or clamping of sympathetic nerves to prevent the transmission of nerve signals. Therefore, this study aims to present a case report of post-sympathectomy nursing management in a patient with Incessant Ventricular Tachycardia. Case Presentation: A 59-year-old female patient was admitted to the high-care unit with a diagnosis of post-sympathectomy, Incessant Ventricular Tachycardia due to Arrhythmogenic Cardiomyopathy. Nursing problems based on NANDA included decreased cardiac output, gas exchange impairment, and activity intolerance. Furthermore, the nursing interventions for the condition included self-care management and collaboration with an anesthesiologist and cardiologist. The interventions encompassed cardiac care, airway management, and activity therapy. Tele-nursing was also conducted through video calls to monitor the patient after hospital care. Results: The planned nursing care was effective in preventing common complications that often occur after the surgical procedure. The most important key aspect is regular maintenance and monitoring. The patient was discharged on the third day after the surgery with no complaints of shortness of breath, palpitations, and gradual resumption of activities. Conclusion: Sympathectomy procedures could successfully be used to treat patients through multidisciplinary collaboration. Furthermore, nurses could emphasize post-operative care management to expedite recovery and improve patient quality of life.
RESUMO
BACKGROUND: Adipose and muscle tissue wasting outlines the cachectic process during tumor progression. The sympathetic nervous system (SNS) is known to promote tumor progression and research suggests that it might also contribute to cancer-associated cachexia (CAC) energetic expenditure through fat wasting. METHODS: We sympathectomized L5178Y-R tumor-bearing male BALB/c mice by intraperitoneally administering 6-hydroxydopamine to evaluate morphometric, inflammatory, and molecular indicators of CAC and tumor progression. RESULTS: Tumor burden was associated with cachexia indicators, including a 10.5% body mass index (BMI) decrease, 40.19% interscapular, 54% inguinal, and 37.17% visceral adipose tissue loss, a 12% food intake decrease, and significant (p = 0.038 and p = 0.0037) increases in the plasmatic inflammatory cytokines IL-6 and IFN-γ respectively. Sympathectomy of tumor-bearing mice was associated with attenuated BMI and visceral adipose tissue loss, decreased interscapular Ucp-1 gene expression to basal levels, and 2.6-fold reduction in Mmp-9 relative gene expression, as compared with the unsympathectomized mice control group. CONCLUSION: The SNS contributes to CAC-associated morphometric and adipose tissue alterations and promotes tumor progression in a murine model.

Leaves of the Khat plant are widely consumed in the Horn of Africa, Yemen and the Jazan region of Saudi Arabia. I have investigated the mode of cardiovascular and autonomic actions of the stimulant cathine from Khat in terms of direct or indirect adrenergic actions in anaesthetised male and female rats, and in isolated tissues. Male and female rats were anaesthetised with pentobarbitone and changes in diastolic blood pressure and cardioaccelerator responses were examined in vehicle-treated or chemically sympathectomised rats. Cathine produced marked tachycardia and smaller blood pressure responses in vehicle-treated animals, with significant rises in heart rate occurring at cathine (0.1 mg/kg). In sympathectomised rats, cardiac actions were greatly attenuated in both male and female animals, with no differences between male and female rats. Although pressor responses to cathine were relatively small, sympathectomy significantly reduced these responses in female, but not male, rats. In rat aorta and spleen, cathine produced almost no direct contractions. It is concluded that cathine acts predominantly indirectly, presumably by the release of noradrenaline, in both male and female rats to produce cardiovascular actions. This may have implications for adverse cardiovascular actions of consumption of the plant Khat, particularly with dried Khat, in which actions of cathine may predominate over those of cathinone.

Background: Perfusion index (PI) has been used as a surrogate marker of sympathetic blockade. This study evaluated changes in PI of bilateral upper extremity after thoracic paravertebral block (PVB) and intertransverse process block (ITPB). Methods: This pilot study included three groups of patients undergoing elective unilateral pulmonary resection under general anesthesia with PVB (n=11) or ITPB (n=10), or urologic procedures with general anesthesia (control group, n=10). Blockades were performed using 10 mL aliquots of 0.5% ropivacaine administered at T3-4, T5-6, and T7-8 intercostal levels immediately after general anesthesia induction. The PI value of the operating side (PI-O) was divided by the contralateral side (PI-CL), and the relative change to baseline was assessed (relative PI-O/PI-CL), with a 50% increase considered meaningful. Results: In all cases within the PVB and ITPB groups, a significant increase in PI was observed following the blockades. The median (1Q, 3Q) intraoperative relative PI-O/PI-CL values were 0.9 (0.8, 1.4), 2.1 (1.4, 2.5), and 1.4 (0.9, 1.9) in the control, PVB, and ITPB groups (P=0.01), respectively. Pairwise comparison revealed a significant difference only between the control and PVB groups (adjusted P=0.01). While the relative PI-O/PI-CL value in the control group generally remained close to 1, occasional fluctuations exceeding 1.5 were noted. Conclusions: PVB induced a noticeable unilateral increase in upper extremity PI, whereas ITPB tended to result in an inconsistent and lesser degree of increase. Monitoring PI values can serve as an indicator of upper extremity sympathetic blockade, but consideration of potential confounders impacting these observations during surgery is essential. Further research is needed to validate these findings.
RESUMO
Technological development in the field of robotics has meant that, in recent years, more and more thoracic surgery departments have adopted this type of approach at the expense of VATS, and today robotic surgery boasts numerous applications in malignant and benign thoracic pathology. Because autonomic nervous system surgery is a high-precision surgery, it is conceivable that the application of RATS could lead to improved outcomes and reduced side effects, but its feasibility has not yet been thoroughly studied. This review identified three main areas of application: (1) standard thoracic sympathectomy, (2) selective procedures, and (3) nerve reconstruction. Regarding standard sympathectomy and its usual areas of application, such as the management of hyperhidrosis and some cardiac and vascular conditions, the use of RATS is almost anecdotal. Instead, its impact can be decisive if we consider selective techniques such as ramicotomy, optimizing selective surgery of the communicating gray branches, which appears to reduce the incidence of compensatory sweating only when performed with the utmost care. Regarding sympathetic nerve reconstruction, there are several studies, although not conclusive, that point to it as a possible solution to reverse surgical nerve interruption. In conclusion, the characteristics of RATS might make it preferable to other techniques and, particularly, VATS, but to date, the data in the literature are too weak to draw any evidence.
RESUMO
OBJECTIVE: In this study, we investigated the safety and practicability of ultra-fast track anesthesia (UFTA) for endoscopic thoracic sympathectomy (ETS). METHODS: A total of 72 patients with palmar hyperhidrosis undergoing ETS were randomly divided into three groups: the UFTA group (group I), the group undergoing single-lumen tracheal intubation with local infiltration anesthesia technique (group II), and the group undergoing single-lumen tracheal intubation with routine anesthesia (group III). Mean arterial pressure (MAP) and heart rate (HR) were recorded for all three groups at the following six time points: Before anesthetics administration (T0), the time of intubating or inserting laryngeal mask airway (T1), the time of incising skin (T2), the time of disconnecting of the right sympathetic nerve (T3), the time of disconnecting of the left sympathetic nerve (T4), the time of withdrawing the tracheal tube or laryngeal mask airway (T5), and the time of transferring the patient to a post-anesthesia care unit (PACU) (T6). The three groups were compared from the following perspectives: surgery duration; anesthesia recovery duration, that is, the duration from discontinuation of anesthesia to extubating the tracheal tube; the dose of propofol and remifentanil per kilogram body mass per unit time interval (the time at the end of the procedure, which lasted from anesthesia induction to incision suturing); and the visual analog scale (VAS) in the resting state in the PACU. RESULTS: Based on pairwise comparisons, the average HR and average MAP values of the three groups differed significantly from T2 to T6 (p < 0.05). As demonstrated by the correlation analysis between remifentanil and propofol with HR and MAP, the doses of the total amount of remifentanil and propofol were lower, and group I used less remifentanil and propofol than group II. No patient in group I experienced throat discomfort following surgery. Patients in groups II and III experienced a range of postoperative discomfort. The VAS scores of groups I and II were significantly lower than those of group III, with group I lower than group II. CONCLUSION: When utilized in ETS, UFTA can provide effective anesthesia for minor traumas. It is safe, effective, and consistent with the enhanced recovery philosophy of fast-track surgery departments.
RESUMO
Cardiac sympathetic denervation (CSD) is a surgical procedure increasingly used for managing ventricular arrhythmia refractory to conventional medical therapy. Long-term outcomes of CSD in patients with systolic heart failure has not been well studied. This observational study aimed to evaluate the medical co-morbidities and outcomes of patients with systolic heart failure who underwent CSD performed as treatment for ventricular arrhythmia refractory to conventional therapy. A retrospective analysis in adult patients with ventricular arrhythmia and systolic heart failure who underwent unilateral or bilateral CSD at a single center was performed. Unadjusted Kaplan-Meier survival curves were constructed to evaluate survival after CSD. Between June 1, 2011 and March 31, 2021, 32 adult patients (age 62 ± 11.6 years, 88% male, left ventricular ejection fraction 22% ± 8.2%) with systolic heart failure underwent unilateral left (n = 4), unilateral right (n = 1), or bilateral CSD (n = 27). Mean survival after CSD was 613 ± 745 days, and the mean time from CSD to death was 291 ± 447 days. The cumulative probability of survival 1 year after CSD was 61.4%. In this single-center observational study, CSD performed for refractory ventricular arrhythmia showed favorable survival in patients with systolic heart failure. In conclusion, this study lays the groundwork for a more in-depth analysis of the potential survival benefits of CSD in this patient group.

Surgical decompression of the thoracic outlet, along with treatment of the involved nerve or vessel, is the accepted treatment modality when indicated. Although neurogenic thoracic outlet syndrome (TOS) is often operated via the axillary approach and venous TOS via the paraclavicular approach, arterial TOS is almost always operated via the supraclavicular approach. The supraclavicular approach provides excellent access to the artery, brachial plexus, phrenic nerve, and the cervical and/or first ribs, along with any bony or fibrous or muscular abnormality that may be causing compression of the neurovascular structures. Even for neurogenic TOS, for which the axillary approach offers good cosmesis, the supraclavicular approach helps with adequate decompression while preserving the first rib. This approach may also be sufficient for thin patients with venous TOS. For arterial TOS, a supraclavicular incision usually suffices for excision of bony abnormality and repair of the subclavian artery.

Background: Ventricular arrhythmias are a leading cause of sudden death. The objective of this study was to characterise the results of patients with ventricular arrhythmias refractory to standard medical management, undergoing Video-assisted thoracoscopic cardiac sympathetic denervation (VAT-CSD) during 2012-2022 in Cali, Colombia. Methods: This was an observational retrospective study, using the Institutional General Thoracic Surgery Database for patient identification and retrospectively reviewing the clinical charts for data description and analysis. Results: Clinical records of 19 patients who underwent VAT-CSD for ventricular arrhythmia were analysed. The patients were predominantly male (73.7%) with an mean age of 62 years. Ischaemic heart disease was the main underlying condition (52.6%); all individuals had a diagnosis of heart failure, with comorbidities such as hypertension (63.1%), acute MI (57.8%) and diabetes (26.3%) also present. The procedure was performed bilaterally in 89.4% of cases and was successful with minimal perioperative complications. Postoperative follow-up showed improvement in symptoms, including a significant reduction in the number of ICD shocks and emergency department visits. Conclusion: VAT-CSD is a viable, safe and palliative therapeutic option for patients with ventricular arrhythmias who have not responded to conventional treatments, achieving a significant decrease in symptoms with low mortality and perioperative complications.
RESUMO
Background: Thoracoscopic sympathetic chain interruption is a definitive and effective therapy for severe primary palmar hyperhidrosis (PPH). Well-known methods include sympathectomy, sympathotomy, and clipping, but the occurrence of compensatory sweating offsets these methods. This study aims to report our experience with thoracoscopic sympathetic chain interruption in a large group of patients of age <18 years with PPH, focusing on surgical outcomes, complication rates, and patient satisfaction. Patients and Methods: This retrospective study included patients who underwent thoracoscopic sympathectomy, sympathotomy, or clipping for severe PPH between April 2008 and March 2023 at the Pediatric Surgery Department, Al-Azhar University Hospitals. Demographic and clinical data, operative steps, postoperative outcomes, complications, and patient satisfaction were reviewed from the patients' medical records. Results: During the 15-year study period, 420 children with PPH underwent bilateral thoracoscopic sympathetic chain interruption by either sympathectomy, sympathotomy, or clipping, with a sex ratio of 60% being females. The mean ages were 12 ± 3.48, 13 ± 2.45, and 13 ± 2.45 years, respectively. Sympathectomy was performed in 190 patients (45.2%), sympathotomy in 170 patients (40.5%), and clipping in 60 patients (14.3%). All patients had completed follow-up, with mean periods of â¼43 ± 5 months, 45 ± 3 months, and 42 ± 6 months, respectively. Complete palmar dryness was achieved in 405 patients (overall 96.4%) (97.8% after sympathectomy, 97.05% after sympathotomy, and 90% after clipping), whereas 2.1%, 2.9%, and 10% of patients experienced symptom recurrence, respectively, denoting significant statistical differences. Overall, 94 patients (22.4%) experienced compensatory sweating. Eventually, 409 patients (97.4%) were satisfied with the outcome, whereas 11 patients (2.6%) reported dissatisfaction, yet no significant differences found. Conclusion: The presented three modalities of thoracoscopic sympathetic chain interruption for PPH in children and adolescents are safe and effective, with overall very high postoperative satisfaction, despite a relatively high rate of compensatory sweating in sympathectomy group. Other major complications in this age population were scanty.
RESUMO
Cervical perivascular sympathectomy (CPVS) can improve communication disorders in children with cerebral palsy (CP); however, there are no research reports on the factors affecting surgical efficacy. This study aimed to establish a nomogram for poor prognosis after CPVS. We collected data from 313 CP patients who underwent CPVS at the Neurosurgery Cerebral Palsy Center of the Second Affiliated Hospital of Xinjiang Medical University from January 2019 to January 2023. Among them, 70% (n = 216) formed the training cohort and 30% (n = 97) the validation cohort. The general data and laboratory examination data of both groups were analyzed. In training cohort, 82 (37.96%) showed improved postoperative communication function. Logistic analysis identified motor function, serum alkaline phosphatase, serum albumin, and prothrombin activity as the prognostic factors. Using these four factors, a prediction model was constructed with an area under the curve (AUC) of 0.807 (95% confidence interval [CI], 0.743-0.870), indicating its ability to predict adverse outcomes after CPVS. The validation cohort results showed an AUC of 0.76 (95% CI, 0.650-0.869). The consistency curve and Hosmer-Lemeshow test (χ2 = 10.988 and p = 0.202, respectively) demonstrated good consistency between the model-predicted incidence and the actual incidence of poor prognosis. Motor function, serum alkaline phosphatase, serum albumin, and prothrombin activity are independent risk factors associated with the prognosis of communication disorders after CPVS. The combined prediction model has a good clinical prediction effect and has promising potential to be used for early prediction of prognosis of CPVS.

OBJECTIVES: Thoracoscopic sympathectomy is an effective treatment for palmar hyperhidrosis. However, compensatory hyperhidrosis occurs frequently as a postoperative complication of the procedure. The goal of this study was to elucidate the clinical significance of thoracoscopic sympathectomy using our surgical procedure. METHODS: Consecutive 151 patients who underwent thoracoscopic sympathectomy for palmar hyperhidrosis were studied. In addition, to investigate patients' satisfaction and long-term quality of life, 111 patients were asked to complete a mailing questionnaire survey, and 84 responded (response rate of 75.7%). RESULTS: All of the 151 patients reported a reduction in palmar sweating during the immediate postoperative period. None of the patients had pneumothorax, hemothorax, Horner's syndrome, or worsening of bradycardia. Based on the questionnaire, the surgical success rate was 98.8%. None of the patients had a recurrence of palmar hyperhidrosis during the long-term postoperative period. However, compensatory hyperhidrosis was reported in 82 patients (97.6%). In total, 94.0% of patients had high levels of postoperative satisfaction. CONCLUSIONS: Thoracoscopic sympathectomy is an effective surgical treatment for palmar hyperhidrosis. By contrast, the careful preoperative explanation of compensatory hyperhidrosis is considered to be very important.
RESUMO
BACKGROUND: The effectiveness of cervical perivascular sympathectomy (CPVS) in enhancing upper limb motor function in children with cerebral palsy is unclear, and the factors that influence the effectiveness of the surgery have not been documented. OBJECTIVE: To investigate the effectiveness of CPVS in enhancing upper limb motor function in children with cerebral palsy and develop a predictive chart for potential associated adverse outcomes METHODS: The study included 187 children with cerebral palsy who underwent CPVS at the Cerebral Palsy Center, Second Affiliated Hospital of Xinjiang Medical University, between January 2018 and January 2022. Patients were categorized into two groups based on prognostic outcomes: those with adverse and favorable prognoses. Demographic and laboratory data were collected and analyzed from both groups. To identify independent predictors of poor post-CPVS upper limb motor function outcomes, statistical techniques, including univariate analysis and binary logistic regression, were applied. Subsequently, these predictors were integrated to formulate a comprehensive predictive model. RESULTS: In this cohort of 187 children with cerebral palsy undergoing CPVS, 68 (36.36%) exhibited a favorable prognosis for upper limb motor function and 119 (63.64%) demonstrated an adverse prognosis. Age, motor function, and serum albumin levels were identified as significant prognostic factors via logistic regression analysis. To develop the model, we divided the sample into a training set (70%, n = 131) and a validation set (30%, n = 56). Employing motor function, serum albumin levels, and age as variables, we crafted a predictive model. The model's performance, reflected by the area under the curve was 0.813 (0.732, 0.894) in the training set and 0.770 (0.647, 0.892) in the validation set, demonstrating its robust predictive capability for post-CPVS adverse outcomes. Furthermore, the consistency curve and Hosmer-Lemeshow test (χ2 = 8.808, p = 0.359) illustrated a strong concordance between the model's predictions of poor prognosis and the actual incidence rate. CONCLUSION: CPVS has been shown to be effective in improving upper limb motor function in patients with cerebral palsy. Independent prognostic factors identified encompass motor function, age, and serum albumin levels. The composite predictive model shows potential for clinical applications.

Radiofrequency ablation (RFA) comparative efficacy of treatments using video-assisted thoracoscopic sympathectomy (VATS) in the long term remains uncertain in patients with palmar hyperhidrosis (PHH). This study aimed to compare the efficacy and safety of RFA and VATS in patients with PHH. We recruited patients aged ≥ 14 years with diagnosed PHH from 14 centres in China. The treatment options of RFA or VATS were assigned to two cohort in patients with PHH. The primary outcome was the efficacy at 1-year. A total of 807 patients were enrolled. After propensity score matching, the rate of complete remission was lower in RFA group than VATS group (95% CI 0.21-0.57; p < 0.001). However, the rates of palmar dryness (95% CI 0.38-0.92; p = 0.020), postoperative pain (95% CI 0.13-0.33; p < 0.001), and surgery-related complications (95% CI 0.19-0.85; p = 0.020) were lower in RFA group than in VATS group, but skin temperature rise was more common in RFA group (95% CI 1.84-3.58; p < 0.001). RFA had a lower success rate than VATS for the complete remission of PHH. However, the symptom burden and cost are lower in patients undergoing RFA compared to those undergoing VATS.Trial Registration: ChiCTR2000039576, URL: http://www.chictr.org.cn/index.aspx .

Hypertension is a major driver of cardiovascular disease with a prevalence of 32-34% in adults worldwide. This poses a formidable unmet challenge for healthcare systems, highlighting the need for enhanced treatment strategies. Since 2017, eight major sham-controlled randomised controlled trials have examined the effectiveness and safety of renal denervation (RDN) as therapy for BP control. Although most trials demonstrated a reduction in systolic 24-hour/daytime ambulatory BP compared to control groups, open to discussion is whether major adverse cardiovascular events (MACE)-driven RDN trials are necessary or whether the proof of BP reduction as a surrogate for better cardiovascular outcomes is sufficient. We conducted an analysis of the statistical methods used in various trials to assess endpoint definitions and determine the necessity for MACE-driven outcome data. Such comprehensive analysis provides further evidence to confidently conclude that RDN significantly reduces blood pressure compared to sham controls. Importantly, this enables the interpolation of RDN trial endpoints with other studies that report on outcome data, such as pharmacological trials which demonstrate a significant reduction in MACE risk with a decrease in BP. Moreover, limitations associated with directly evaluating outcome data further support the use of BP as a surrogate endpoint. For example, conducting lengthier trials with larger numbers of participants to ensure robust statistical power presents a substantial challenge to evaluating outcome data. Thus, in light of the crucial need to tackle hypertension, there are notable advantages of considering BP as a surrogate for outcome data.
RESUMO
To evaluate the efficacy of perivascular sympathectomy in managing adventitia layer-related long-segment tubular stenosis of cervical segment (C1) internal carotid arteries (ICAs) in a cohort where conventional medical and endovascular interventions were not viable options, we retrospectively analyzed 20 patients (8 males, 12 females, aged 41-63 years) who underwent perivascular sympathectomy for long-segment (>5 cm) tubular cervical ICA stenosis (non-atherosclerotic, non-intima related, and nondolichoarteriopathic) between 2017 and 2023. The procedure aimed to alleviate symptoms such as hemiparesis, pulsatile tinnitus, and migraines associated with transient ischemic attacks (TIAs). Preoperative and postoperative symptoms were assessed, and patient follow-up was conducted by MR angiography and perfusion studies. Postoperatively, 10 out of 11 migraine sufferers (90.9%) reported complete cessation of symptoms, while one patient (9.09%) experienced reduction in frequency and intensity. In cases of tinnitus, six out of nine patients (66.6%) reported complete resolution, two (22.2%) had reduced symptoms, and one (11.1%) saw no change. Regarding motor function, all 12 patients (100%) with initial hemiparesis (30-40% loss of motor function) showed complete recovery postoperatively. There was no TIA attack among the patients after the procedure in the mean two-year follow-up. Perivascular sympathectomy has shown promising results in alleviating symptoms and preventing recurrent cerebrovascular events in long-segment tubular stenosis of cervical ICAs.
RESUMO
Objective: This study assesses the efficacy of distal periarterial sympathectomy in treating chronic digital ischemia by evaluating clinical outcomes of surgery. Methods: A systematic literature review of distal sympathectomy for chronic digital ischemia was conducted. Data extracted included study design, patient statistics, aetiology, follow-up duration, sympathectomy level, and surgical outcomes. Results: 21 studies were analysed, containing a total of 337 patients, 324 hands, and 398 digits. Patient age ranged from 23.2 to 56.6 years. Causes of ischemia included Scleroderma, Raynaud's disease, atherosclerosis/Buerger's disease, systemic lupus erythematosus/discoid lupus, undifferentiated rheumatic disorder/mixed connective tissue disease, CREST syndrome, trauma and unknown diagnoses. Common digital artery sympathectomy was mostly performed. Follow-up spanned 12-120 months. Outcomes: Distal sympathectomy led to reduced pain in 94.7 % patients. Complete resolution of ulceration was seen in 73 % patients. Subsequent amputation was required in 28 % patients. Other complications were reported in 24.1 % patients. Conclusions: This study indicates that distal periarterial sympathectomy may effectively treat chronic digital ischemia, offering pain relief and resolution of digital ulceration. However, risks of complications and amputation persist. Further research is required to inform patient selection and establish the optimal technique and extent of distal sympathectomy surgery, before it can be considered a valid treatment option.
RESUMO
BACKGROUND: There is a lack of research to determine the efficacy of cervical perivascular sympathectomy (CPVS) in children with cerebral palsy (CP). OBJECTIVE: This study aimed to evaluate the efficacy of CPVS in children with CP and analyze the associated influential factors. METHODS: Using the method of retrospective cohort studies, children who underwent CPVS were included in the CPVS group, whereas those who underwent selective posterior rhizotomy (SPR) were included in the SPR group. The Communication Function Classification System (CFCS) and Teacher Drooling Scale (TDS) were used to evaluate the communication function and salivation in the two groups before and 12 months after surgery and compare the surgical efficiency between the two groups, and the factors affecting the efficacy were screened by binary logistic regression. RESULTS: The study included 406 patients, 202 in the CPVS group and 204 in the SPR group. No significant differences were observed in the baseline characteristics (p > 0.05). The surgical efficacy of the CPVS group (47.01%) was significantly higher than that in the SPR group (9.81%) (χ2 = 71.08, p < 0.001). Binary logic regression analysis showed that preterm birth and Gross Motor Function Classification System (GMFCS) grade were influencing factors of surgical efficacy. Eighteen patients developed postoperative complications. CONCLUSION: CPVS is a safe and effective surgery for cerebral palsy. Preterm birth and GMFCS grade are independent factors affecting the efficacy of surgery.

OBJECTIVE: This narrative review examines how speculative belief that the autonomic nervous system causes Meniere's Disease (MD) led otolaryngologists to adopt invasive surgical procedures and medical treatments still offered today. DATA SOURCES: Google Scholar, PubMed. REVIEW METHODS: A comprehensive literature review (1860-2022) was performed using the terms "Meniere AND (sympathetic OR sympathectomy OR vasomotor OR cervical ganglion)," returning 5360 items. All abstracts were briefly reviewed, relevant publications selected for further study, and key articles discussed by all authors. As it became clear that betahistine was related to the historical narrative, an additional search was performed using "Betahistine AND Meniere AND (vasomotor OR sympathetic OR sympathectomy OR cervical ganglion OR autonomic)," which yielded 336 results. RESULTS: In the 19th and 20th centuries, growing knowledge of human anatomy led the scientific community to speculate that autonomic dysregulation caused many medical conditions. Excessive sympathetic mediated vasomotor changes were thought to cause hypertension, ischemia, and tissue damage. Clinicians applied the hypothesis to MD, assigning the sympathetic nervous system responsible for vertigo secondary to paroxysmal vasospasm and for hearing loss to poor cochlear nutrition. Despite limited animal experiments and isolated clinical observations, otolaryngologists performed sympathectomies, and, in the 1970s, replaced the procedure with betahistine as an alternative medical treatment. CONCLUSION: Premature excitement about a plausible hypothesis led to unnecessary and unwarranted operations. Despite absent evidence of sympathetic overactivation in MD, surgeons eagerly adopted sympathectomies, and later betahistine. Rigorous evaluation of the validity of these treatment practices is needed. LEVEL OF EVIDENCE: 5 Laryngoscope, 134:535-542, 2024.
