Preventable Stroke and Brain Injury After Missed Aortic Dissection

Table of Contents

    A patient arrives at the emergency room with sudden, tearing pain radiating through the chest and into the back. Minutes later, they begin slurring their words and losing feeling on one side of their body. If the emergency team recognizes these signs as a possible aortic dissection and acts quickly, the patient has a real chance at survival without permanent damage. If the warning signs are missed, dismissed, or misattributed to something less serious, the same patient can suffer a catastrophic, often preventable stroke or permanent brain injury within hours.

    A missed aortic dissection stroke is one of the most devastating outcomes in emergency medicine, precisely because it is so often preventable with timely diagnosis and treatment. The Becker Law Firm’s medical malpractice attorneys represent families throughout Cleveland and Ohio whose loved ones suffered catastrophic harm because a hospital or emergency provider failed to meet the standard of care. Call us today at 216-480-4620 to discuss what happened to you or your loved one.

    What Is Aortic Dissection and Why Is It Life-Threatening?

    The aorta is the body's largest artery, responsible for carrying oxygen-rich blood from the heart to the brain and the rest of the body. According to the Cleveland Clinic, an aortic dissection occurs when a tear develops in the inner layer of the aortic wall, allowing blood to force its way between the layers of the artery and create a false channel. This weakens the artery and can disrupt or completely block blood flow to critical organs, including the brain.

    Aortic dissection is a true medical emergency. Without immediate diagnosis and treatment, the mortality rate can climb rapidly with each passing hour, and survivors who experience delayed treatment often face permanent, life-altering complications.

    How Aortic Dissection Leads to Stroke and Brain Injury

    When an aortic dissection extends into or affects the carotid arteries, which supply blood directly to the brain, the result can be cerebral malperfusion, a dangerous reduction in blood flow to brain tissue. 

    This interruption deprives brain cells of oxygen, and depending on the duration and severity of the disruption, it can result in an ischemic stroke, permanent neurological damage, or death. The connection between the aorta and the brain's blood supply is precisely why aortic dissection can produce stroke-like symptoms that are so easily mistaken for a primary neurological event rather than a cardiovascular emergency.

    Statistics: How Often Does Stroke Occur With Aortic Dissection?

    Stroke and other neurological complications are a well-documented risk of aortic dissection, particularly in Type A dissections involving the ascending aorta, which are more likely to affect blood flow to the brain. 

    According to the AHA Journals, the risk of stroke sits between a 6% to 30% chance depending on other factors such as age and the risk of hypertension.

    Because these neurological symptoms can appear alongside or even before classic chest pain, emergency providers must remain alert to the underlying cardiovascular cause rather than treating the stroke symptoms in isolation.

    Red Flags Emergency Providers Must Recognize

    Emergency medicine providers are trained to recognize a specific constellation of warning signs that should immediately raise suspicion for aortic dissection, including:

    • Sudden, severe, tearing or ripping chest or back pain
    • Pulse deficits or a significant blood pressure difference between arms
    • New neurological deficits, such as slurred speech, weakness, or facial drooping
    • Unexplained hypotension or shock
    • Pleural effusion visible on imaging
    • Troponin positivity without a clear cardiac explanation
    • ECG changes suggestive of acute coronary syndrome without a confirmed cardiac cause

    When these red flags are present, either individually or in combination, the standard of care generally requires providers to move quickly toward definitive imaging rather than assuming a more common, less dangerous diagnosis.

    When Delayed Diagnosis Becomes Medical Malpractice in Ohio

    Not every missed or delayed diagnosis of aortic dissection amounts to medical malpractice. Whether a case rises to that level depends on whether the treating providers deviated from the accepted standard of care given the symptoms and information available to them at the time.

    The Standard of Care for Aortic Dissection

    When aortic dissection is suspected based on presenting symptoms, the accepted standard of care generally requires immediate CT angiography to confirm or rule out the diagnosis, aggressive blood pressure control to reduce further stress on the aortic wall, and urgent surgical consultation, particularly for Type A dissections that often require emergency surgical repair. Failing to pursue this workup when red flags are present can constitute a breach of the standard of care.

    Common Diagnostic Failures in Emergency Departments

    Diagnostic failures in these cases often stem from a few recurring patterns, including:

    • Anchoring on a more common diagnosis, such as a heart attack or a primary stroke, without adequately considering aortic dissection as an underlying cause
    • Discharging a patient without appropriate imaging despite red flag symptoms
    • Failing to order a CT angiogram promptly
    • Failing to recognize the significance of a pulse deficit or blood pressure discrepancy between limbs

    Complications of Missed or Delayed Aortic Dissection

    When aortic dissection is missed or diagnosis is delayed, the resulting complications can be severe and permanent, including:

    • Ischemic stroke
    • Permanent brain injury
    • Paralysis
    • Organ damage from interrupted blood flow
    • Cardiac tamponade
    • Aortic rupture
    • Death

    When a preventable outcome like this occurs, families are often left not only grieving or caring for a loved one with permanent injuries, but also searching for answers about whether the care their loved one received actually met the standard the situation demanded. 

    Your Legal Options After Preventable Stroke or Brain Injury

    If a loved one suffered a stroke, brain injury, paralysis, or died because an aortic dissection was missed or diagnosed too late, Ohio law may allow you to pursue a medical malpractice claim. To succeed, a claim generally must establish that the provider owed a duty of care, that the provider breached that duty by failing to meet the accepted standard of care, that the breach directly caused the resulting injury, and that the patient suffered real, compensable damages as a result.

    Ohio’s statute of limitations law generally requires medical malpractice claims to be filed within one year of the injury, or one year from when the injury was discovered or reasonably should have been discovered. Given this relatively short window, it is important to speak with an attorney as soon as possible after learning that a missed diagnosis may have contributed to a stroke, brain injury, or death.
