STROKE MEDICAL NEGLIGENCE IGNORING TRANSIENT ISCHEMIC ATTACK (TIA) SYMPTOMS
John Whelan Solicitor with specialist expertise in Stroke Medical Negligence gives a case example of Ignoring Transient Ischemic Attack (TIA) Symptoms
An example of a case where Transient Ischemic Attack (TIA) symptoms were ignored, leading to a severe stroke and poor outcomes for the Patient:
Case Example: Ignoring Transient Ischemic Attack (TIA) Symptoms
A Patient with a history of hypertension, hyperlipidemia, and smoking, presented to the Patients GP with complaints of sudden onset numbness and weakness in the right arm, along with difficulty speaking. The Patient also experienced blurred vision in the right eye. These symptoms lasted for about 15 minutes and then resolved completely.
Initial Consultation:
a) During the visit to the GP the Patient described the symptoms, noting that they had gone away on their own and felt completely normal after the episode. The Patient mentioned feeling a bit tired but attributed it to stress and lack of sleep.
b) The GP conducted a brief neurological exam, which appeared to be normal, as the Patient was now asymptomatic. The Patients blood pressure was 160/95 mmHg, and the Patients cholesterol levels were elevated, but the Patients doctor did not consider these factors in the context of neurological symptoms.
c) The Patients GP attributed the symptoms to temporary numbness due to muscle strain or perhaps anxiety, given that the Patient had been under stress at work. The GP did not recognise the episode as a Transient Ischemic Attack (TIA) or discuss the potential risks of a stroke.
d) No further testing, such as an MRI or CT scan, was ordered. The Patient was advised to reduce stress and was given a referral for a follow up visit to address the Patient’s blood pressure and cholesterol levels, but there was no emphasis on the urgency of further evaluation for TIA symptoms.
Failure to Act on TIA Symptoms:
Ignoring the Warning Signs of a TIA:
a) The episode the Patients experienced, with sudden numbness, weakness, and difficulty speaking, were classic symptoms of a TIA, which can last for a few minutes and resolve completely. TIAs are considered "warning strokes" because they increase the risk of a full blown stroke in the near future.
b) However, the physician failed to recognise these as signs of a potential stroke and dismissed them as something benign, leading to no immediate action to evaluate the cause of the symptoms or address the risk.
Lack of Urgent Imaging or Further Investigation:
a) The GP did not order any imaging studies (such as a CT scan or MRI) to assess the possibility of underlying vascular issues, such as a blockage or narrowing of blood vessels, which could have caused the TIA. A carotid ultrasound or echocardiogram was also not considered.
b) The lack of diagnostic evaluation delayed the identification of a potential embolism or atherosclerosis that could have been the underlying cause of the TIA.
Failure to Educate on Stroke Risks:
The Patient was not informed about the high risk of stroke following a TIA, nor was the Patient advised to seek emergency medical help if the Patient experienced similar symptoms in the future. The Patient was not instructed to immediately seek help if the Patient experienced any recurrence of symptoms like those just had.
Outcome of Ignored TIA Symptoms:
a) Three weeks later, the Patient suffered a severe ischemic stroke while at home. The stroke affected the left side, causing right sided paralysis (hemiparesis), and the Patient had significant difficulty speaking and understanding speech (aphasia).
b) After the stroke, the Patient was rushed to the hospital, where a CT scan revealed a large ischemic infarct in the right middle cerebral artery (MCA) territory.
c) Despite receiving tPA (tissue plasminogen activator), which was within the therapeutic window, the delay in treatment and the large size of the infarct meant that the Patient was left with permanent neurological deficits.
d) The Patient required extensive rehabilitation for motor and speech deficits, and the Patients overall quality of life was significantly impacted. The Patient also experienced significant emotional distress and depression due to the loss of independence and chronic health issues following the stroke.
Important Points of the Case:
Failure to Recognise and Act on TIA Symptoms.
Lack of Diagnostic Testing and Imaging.
Failure to Educate About Stroke Risks.
