Background: Refractory chronic craniofacial pain is a debilitating condition with limited treatment options. This case report presents the use of percutaneous computed tomography-guided trigeminal tractotomy-nucleotomy under general anesthesia in a patient with refractory trigeminal neuralgia and post-treatment anesthesia dolorosa. This case report expands the use of TR-NC to include treatment-resistant post-treatment anesthesia dolorosa and introduces real-time verification under anesthesia, potentially broadening access and improving precision, while highlighting the need for further research on long-term efficacy and patient selection for this promising technique. Case presentation: A 50-year-old woman with 12 years of chronic facial pain in the opthalmic and maxillary trigeminal branches despite multiple surgical and medical interventions underwent computed tomography-guided trigeminal tractotomy-nucleotomy under general anesthesia. Initial pain relief was significant, but symptoms gradually returned within 12 months. Transient mild ataxia was the only complication. Conclusion: This case suggests trigeminal tractotomy-nucleotomy under general anesthesia with real-time verification may be a valuable option for patients with refractory post-treatment anesthesia dolorosa. However, the transient nature of pain relief necessitates further investigation of long-term outcomes and optimal patient selection. [ABSTRACT FROM AUTHOR]

Predicting recovery potential of patients with aneurysmal subarachnoid hemorrhage (aSAH) is challenging. We investigated whether the gray-to-white matter ratio (GWR) predicts recovery of cognitive function (CF) and quality of life (QOL) of these patients. We analyzed data of 69 patients with aSAH. Patients' demographics, comorbidities, and neurological status were recorded. One year after aSAH, Montreal Cognitive Assessment (MoCA) and Short Form-36 (SF-36) tests were administered to the patients, and brain volumes of patients were examined using MRI. Three years after aSAH, MoCA and SF-36 tests were conducted again. Differences between the test scores 1 and 3 years after aSAH were evaluated (ΔMoCA and ΔSF-36). Patients with ΔMoCA ≥ 4 points and those with ΔSF-36 ≥ 8 points were referred to as good MoCA and SF-36 recovery, respectively. ΔMoCA correlated with GWR in male and female patients (females: p < 0.001, R2 = 0.581; males: p < 0.001, R2 = 0.481). In female patients, GWR > 1.34 predicted good MoCA recovery with 82.3% sensitivity and 80% specificity, and in male patients, GWR > 1.36 predicted good MoCA recovery with 80% sensitivity and 95% specificity. ΔSF-36 correlated with GWR in male and female patients (females: p < 0.001, R2 = 0.479; males: p < 0.001, R2 = 0.627). In female patients, GWR > 1.35 predicted good SF-36 recovery with 74% sensitivity and 84% specificity, and in male patients, GWR > 1.38 predicted good SF-36 recovery with 72% sensitivity and 92% specificity. GWR is a good predictor of the recovery of CF and QOL in patients with aSAH and, thus, can help physicians to better organize rehabilitation of patients. [ABSTRACT FROM AUTHOR]

Background: Corrective craniosynostosis surgery is often associated with a large amount of blood loss and metabolic disturbances. In the present study, we investigated the severity, duration of metabolic disturbances, and causal risk factors in infants. Methods: A retrospective analysis was performed of 36 infants who underwent craniosynostosis surgery. We analyzed the following: demographics, duration of surgery, intraoperative blood loss, RBC, FFP and fluids transfused, urine output, hemodynamic parameters, and electrolyte and base deficit (BD) values. The lowest intraoperative BD value and time required (period I: <6 h; period II: 6-12 h; period III: >12 h) for BD values to return to normal (-4 to +2) in the postoperative period were determined. In addition, we recorded the postoperative length of stay in the ICU and hospital, postoperative blood loss, and early complications. Results: We detected that 88 % of the patients had subnormal BD levels and 22 % had metabolic acidosis. The lowest average BD measured during the operation was -8.4 ± 2.6 mmol/l. We carried out a multiple regression analysis, which revealed that lower BD values were associated with a longer duration of hypotension ( p = 0.002, R = 0.453) and greater intraoperative blood loss ( p = 0.002, R = 0.674). We examined the amount of intraoperative blood loss and found that that there were fewer blood product transfusions in period I patients and longer hypotensive episodes in period III patients. Also, a negative correlation was detected between the lowest intraoperative BD value with ICU duration ( p = 0.004, r = -0.466) and hospital stay ( p < 0.001, r = -0.764). Conclusion: Almost all patients developed intraoperative negative BD, which was prolonged in the postoperative period. The most important risk factors for developing negative BD are the amount of blood loss and duration of hypotension. [ABSTRACT FROM AUTHOR]
