Cervical Artery Dissection Caused by Electrical Cupping Therapy with High-Negative Pressure – Case Report

Zuhorn F, Schäbitz W-R, Oelschläger C, Klingebiel R, Rogalewski A. Cervical Artery Dissection Caused by Electrical Cupping Therapy with High-Negative Pressure – Case Report. Journal of Stroke and Cerebrovascular Diseases. 2020;29(11): 105207.Cervical artery dissection is an important cause of stroke in the young. The etiology is still discussed controversial. The most obvious reason for a dissection of extracranial arteries is due to a trauma, eg. after car accidents or other high speed traumas such as high-velocity road traffic accidents. Besides these clear cases, chiropractic neck maneuvers represent potential reasons for vessel injuries. Case presentation: We here report a rare case of secondary cervical artery dissection after so-called cupping therapy and a preventive treatment with a direct oral anticoagulant. Conclusions: Therapists using this technique should be aware of the potentially devastating side effects. The diagnosis of ICA dissection should be considered with any new onset of unknown neck pain or headache, specifically in combination with neurological deficits

Detection of Atrial Fibrillation on Stroke Units: Comparison of Manual versus Automatic Analysis of Continuous Telemetry

Rogalewski A, Plümer J, Feldmann T, et al. Detection of Atrial Fibrillation on Stroke Units: Comparison of Manual versus Automatic Analysis of Continuous Telemetry. Cerebrovascular Diseases. 2020;49(6):647-655.Background: Detection of atrial fibrillation (AF) is one of the primary diagnostic goals for patients on a stroke unit. Physician-based manual analysis of continuous ECG monitoring is regarded as the gold standard for AF detection but requires considerable resources. Recently, automated computer-based analysis of RR intervals was established to simplify AF detection. The present prospective study analyzes both methods head to head regarding AF detection specificity, sensitivity, and overall effectiveness. Methods: Consecutive stroke patients without history of AF or proof of AF in the admission ECG were enrolled over the period of 7 months. All patients received continuous ECG telemetry during the complete stay on the stroke unit. All ECGs underwent automated analysis by a commercially available program. Blinded to these results, all ECG tracings were also assessed manually. Sensitivity, specificity, time consumption, costs per day, and cost-effectiveness were compared. Results: 216 consecutive patients were enrolled (70.7 ± 14.1 years, 56% male) and 555 analysis days compared. AF was detected by manual ECG analysis on 37 days (6.7%) and automatically on 57 days (10.3%). Specificity of the automated algorithm was 94.6% and sensitivity 78.4% (28 [5.0%] false positive and 8 [1.4%] false negative). Patients with AF were older and had more often arterial hypertension, higher NIHSS at admission, more often left atrial dilatation, and a higher CHA2DS2-VASc score. Automation significantly reduced human resources but was more expensive compared to manual analysis alone. Conclusion: Automatic AF detection is highly specific, but sensitivity is relatively low. Results of this study suggest that automated computer-based AF detection should be rather complementary to manual ECG analysis than replacing it
