RESUMEN
Background: The optimal time to restart direct oral anticoagulants (DOACs) for nonvalvular atrial fibrillation (NVAF) after traumatic intracranial hemorrhage (tICH) is unknown. Physicians must weigh the risk of recurrent hemorrhage against ischemic stroke. We investigated rates of stroke while holding anticoagulation, hemorrhage after anticoagulation resumption, and factors associated with the decision to restart anticoagulation. Methods: Patients presenting to our level I trauma center for tICH while on a DOAC for NVAF were retrospectively reviewed over 2 years. Age, sex, DOAC use, antiplatelet use, congestive heart failure, hypertension, age, diabetes, previous stroke, vascular disease, sex score for stroke risk in NVAF, injury mechanism, bleeding pattern, Injury Severity Score, use of a reversal agent, Glasgow Coma Scale at 24 hours, hemorrhage expansion, neurosurgical intervention, Morse Fall Risk, DOAC restart date, rebleed events, and ischemic stroke were recorded to study rates of recurrent hemorrhage and stroke, and factors that influenced the decision to restart anticoagulation. Results: Twenty-eight patients sustained tICH while on a DOAC. Fall was the most common mechanism (89.3%), and subdural hematoma was the predominant bleeding pattern (60.7%). Of the 25 surviving patients, 16 patients (64%) restarted a DOAC a median 29.5 days after tICH. One patient had recurrent hemorrhage after resuming anticoagulation. One patient had an embolic stroke after 118 days off anticoagulation. Age >80, Injury Severity Score ≥16, and expansion of tICH influenced the decision to indefinitely hold anticoagulation. Conclusion: The low stroke rate observed in this study suggests that holding DOACs for NVAF for 1 month is sufficient to reduce the risk of stroke after tICH. Additional data are required to determine optimal restart timing.
RESUMEN
Background: Subacute subdural hematoma (SDH) is a common pathology most frequently affecting older patients and may be treated operatively through burr holes versus craniotomy or minimally invasively with bedside twist drill craniostomy. Less invasive intervention is favored when possible given a frequently comorbid population. The subdural evacuation port system (SEPS) is a popular treatment option that warrants investigation and reporting of its use and outcomes. Methods: A retrospective review of consecutive patients undergoing SEPS drain placement for chronic or mixed density SDH between 2010 and 2021 was conducted. Outcomes of SDH recurrence, need for operating room procedure after SEPS placement, discharge disposition other than home, and modified Rankin Scale score <3 at discharge were modeled with logistic regression using multiple demographic, clinical, and radiographic features. Results: Ultimately, 86 patients (mean age 68) were included in the analysis with 66 (78%) presenting with mixed-density SDHs. Radiographic factors such as hematoma thickness and midline shift were not associated with the need for an operating room procedure after SEPS placement or discharge disposition. However, the presence of septations and mixed-density SDH versus chronic SDH was significantly associated with increased odds of requiring an operative intervention after SEPS placement. Conclusions: Subacute SDHs are a frequent neurosurgical issue in patient populations where less invasive measures are favored. SEPS drainage continues to be an effective treatment option. However, the presence of septations and mixed-density SDHs has a significantly increased odds of requiring surgical intervention that must be considered in the decision to pursue SEPS drainage.
RESUMEN
BACKGROUND: The increasing shift toward a more generalized medical undergraduate curriculum has led to limited exposure to subspecialties, including neurosurgery. The lack of standardized teaching may result in insufficient coverage of core learning outcomes. Social media (SoMe) in medical education are becoming an increasingly accepted and popular way for students to meet learning objectives outside formal medical school teaching. We delivered a series of case-based discussions (CbDs) over SoMe to attempt to meet core learning needs in neurosurgery and determine whether SoMe-based CbDs were an acceptable method of education. METHODS: Twitter was used as a medium to host 9 CbDs pertaining to common neurosurgical conditions in practice. A sequence of informative and interactive tweets were formulated before live CbDs and tweeted in progressive order. Demographic data and participant feedback were collected. RESULTS: A total of 277 participants were recorded across 9 CbDs, with 654,584 impressions generated. Feedback responses were received from 135 participants (48.7%). Participants indicated an increase of 77% in their level of knowledge after participating. Of participants, 57% (n = 77) had previous CbD experience as part of traditional medical education, with 62% (n = 84) receiving a form of medical education previously through SoMe. All participants believed that the CbDs objectives were met and would attend future sessions. Of participants, 99% (n = 134) indicated that their expectations were met. CONCLUSIONS: SoMe has been shown to be a favorable and feasible medium to host live, text-based interactive CbDs. SoMe is a useful tool for teaching undergraduate neurosurgery and is easily translatable to all domains of medicine and surgery.
