Unruptured intracranial aneurysms (UIAs) are commonly acquired vascular lesions that form an outpouching of the arterial wall due to wall thinning. The prevalence of UIAs in the general population is 3.2%. In contrast, an intracranial aneurysm may be manifested after rupture with classic presentation of a thunderclap headache suggesting aneurysmal subarachnoid hemorrhage (SAH). Previous consensus suggests that although small intracranial aneurysms (<7 mm) are less susceptible to rupture, aneurysms larger than 7 mm should be treated on a case-by-case basis with consideration of additional risk factors of aneurysmal growth and rupture. However, this distinction is outdated. The PHASES score, which comprises data pooled from several prospective studies, provides precise estimates by considering not only the aneurysm size but also other variables, such as the aneurysm location. The International Study of Unruptured Intracranial Aneurysms is the largest observational study on the natural history of UIAs, providing the foundation to the current guidelines for the management of UIAs. Although SAH accounts for only 3% of all stroke subtypes, it is associated with considerable burden of morbidity and mortality. The initial management is focused on stabilizing the patient in the intensive care unit with close hemodynamic and serial neurologic monitoring with endovascular or open surgical aneurysm treatment to prevent rebleeding. Since the results of the International Subarachnoid Aneurysm Trial, treatment of aneurysmal SAH has shifted from surgical clipping to endovascular coiling, which demonstrated higher odds of survival free of disability at 1 year after SAH. Nonetheless, aneurysmal SAH remains a public health hazard and is associated with high rates of disability and death.
Background: Recent advancements have lowered national acute stroke mortality, yet posthospital care and readmission rates remain challenges. A personal health assistant (PHA) may help manage the spectrum of posthospital care. We hypothesized that a PHA application (app) would be associated with high poststroke patient care satisfaction and might prevent hospital readmission.Methods: This is a case series of acute stroke patients admitted to a single, tertiary care, comprehensive stroke center (Mayo Clinic, Jacksonville, Florida) who were offered a personal health assistance through a smart phone app. Patients were screened based on having a cerebrovascular event and the ability to use a necessary device. All patients received the standard poststroke discharge protocol, the PHA app, and the 30-day Likert scale survey. Results:We screened 21 patients and enrolled 3 (14%) before premature financial closure. Two of the 3 patients rated the app highly, and the third patient had not started using it. Of the ineligible patients, 4 had no device, 3 declined enrollment, and 2 were not able to use the device. One of the 2 patients who used the PHA app was readmitted for new stroke symptoms.Conclusions: Both patients who used the app were very satisfied with the PHA and their posthospital care coordination. This study had an enrollment rate of about 14% due to various factors, including limited access or utilization of necessary technology. Though limited by final patient sample size and early termination from funding, this study provides useful information about developing future mobile health apps for acute stroke patients.
New studies suggest that pre-hospital treatment of stroke with mobile stroke units and telestroke technology may lead to earlier stroke therapy with intravenous tissue plasminogen activator (tPA), and recent studies show tPA can be given in previously contraindicated situations. More rapid automated CT perfusion and angiography may demonstrate a vascular penumbra for neuroendovascular intervention. Further, the greatest advance in acute stroke treatment since 2014 is the demonstration that neuroendovascular catheter-based thrombectomy with stent retrievers recanalizing intracranial large vessel occlusion (LVO) improves both recanalization and long-term outcomes in several trials. Hemorrhagic transformation and severe large infarct cerebral edema remain serious post-stroke challenges, with new guidelines describing who and when patients should get medical or surgical intervention. The adage "time is brain" directs the most evidence-based approach for rapid stroke diagnosis for tPA eligible and LVO recanalization using an orchestrated team approach. The neurocritical care unit is the appropriate location to optimize stroke outcomes for the most severely affected stroke patients.
