Comparison of Clinical Outcomes of Anterior Circulation Stroke and Posterior Circulation Stroke in Acute Ischemic Stroke Patients

Introduction

Ischemic stroke is a leading cause of morbidity and mortality worldwide, accounting for approximately 80% of all stroke cases. The majority of ischemic strokes occur due to the blockage of blood vessels that supply the brain, resulting in a significant loss of brain tissue and function. Among the various types of ischemic strokes, posterior circulation stroke is a relatively rare but severe condition, accounting for approximately 20% of all ischemic stroke cases. Posterior circulation stroke involves the brain structures supplied by the vertebrobasilar artery system, including the brainstem, cerebellum, midbrain, thalamus, and temporal and occipital cortices.

Background

Acute ischemic stroke is a medical emergency that requires prompt and effective treatment to minimize long-term disability and improve patient outcomes. The clinical outcomes of ischemic stroke patients are influenced by various factors, including the location and severity of the stroke, the effectiveness of treatment, and the patient's overall health status. In this study, we aimed to compare the clinical outcomes of anterior circulation stroke and posterior circulation stroke in acute ischemic stroke patients.

Methods

A descriptive analytic study was conducted at the Adam Malik Medan Hajj General Hospital, involving 56 acute ischemic stroke patients. The study used a latitude cutting method to compare the clinical outcomes of anterior circulation stroke and posterior circulation stroke patients. The Modified Rankin Scale (MRS) and Barthel Index (BI) were used to assess the patients' functional status and disability levels.

Results

The results of the study showed a significant difference in the MRS and BI values between the two groups of patients. On the 7th and 14th days after the stroke, the posterior circulation stroke group had a worse MRS value and a lower BI value compared to the anterior circulation stroke group. This indicates that posterior circulation stroke patients tend to experience more severe disability compared to patients with anterior circulation stroke.

The Importance of Differences in Clinical Results

The difference in clinical results between anterior and posterior circulation stroke has important implications for treatment and rehabilitation strategies. Posterior circulation stroke patients require special attention and more intensive intervention to minimize long-term disability. Early recognition and treatment of posterior circulation stroke are critical to improving patient outcomes and reducing the risk of long-term disability.

Factors Causing Differences in Clinical Results

Several factors contribute to the differences in clinical results between anterior and posterior circulation stroke. These factors include:

Location of Lesions

The location of the lesion in posterior circulation stroke often involves vital brain structures responsible for motor, sensory, and cognitive function, such as the brainstem and cerebellum. This can cause more severe disability and long-term consequences.

Stroke Type

Posterior circulation stroke is often caused by embolism originating from the heart, which tends to cause greater blockage of blood vessels and broader brain damage. This can lead to more severe disability and poorer outcomes compared to anterior circulation stroke.

Initial Handling

Patients with posterior circulation stroke are often late to receive proper medical treatment, increasing the risk of brain damage and more severe disability. Early recognition and treatment of posterior circulation stroke are critical to improving patient outcomes.

Recommendations

Based on the results of this study, several recommendations can be made to improve patient outcomes and reduce the risk of long-term disability:

Increase public awareness: Efforts should be made to increase public awareness about the importance of early handling of posterior circulation stroke.
Further research: Further research is needed to understand the risk factors and brain damage mechanisms in posterior circulation strokes, so that more effective prevention and treatment strategies can be developed.
Improved treatment protocols: Treatment protocols for posterior circulation stroke should be developed and implemented to ensure that patients receive timely and effective treatment.
Increased access to care: Increased access to care and rehabilitation services should be provided to patients with posterior circulation stroke to minimize long-term disability.

Conclusion

In conclusion, this study highlights the importance of comparing clinical outcomes between anterior and posterior circulation stroke in acute ischemic stroke patients. The results of the study show that posterior circulation stroke patients tend to experience more severe disability compared to patients with anterior circulation stroke. Several factors contribute to the differences in clinical results, including the location of lesions, stroke type, and initial handling. Recommendations are made to improve patient outcomes and reduce the risk of long-term disability. Further research is needed to understand the risk factors and brain damage mechanisms in posterior circulation strokes, so that more effective prevention and treatment strategies can be developed.
Frequently Asked Questions (FAQs) about Anterior and Posterior Circulation Stroke

Q: What is the difference between anterior and posterior circulation stroke?

A: Anterior circulation stroke involves the brain structures supplied by the anterior cerebral artery, including the frontal, parietal, and temporal lobes. Posterior circulation stroke, on the other hand, involves the brain structures supplied by the vertebrobasilar artery system, including the brainstem, cerebellum, midbrain, thalamus, and temporal and occipital cortices.

Q: What are the symptoms of anterior and posterior circulation stroke?

A: The symptoms of anterior and posterior circulation stroke can be similar, including weakness or numbness in the face, arm, or leg, difficulty speaking or understanding speech, and vision changes. However, posterior circulation stroke can also cause symptoms such as dizziness, loss of balance, and difficulty swallowing.

Q: What are the risk factors for posterior circulation stroke?

A: The risk factors for posterior circulation stroke include:

Age: Posterior circulation stroke is more common in older adults.
Hypertension: High blood pressure is a major risk factor for posterior circulation stroke.
Diabetes: Diabetes is a risk factor for posterior circulation stroke.
Smoking: Smoking is a risk factor for posterior circulation stroke.
Family history: A family history of stroke or heart disease can increase the risk of posterior circulation stroke.

Q: How is posterior circulation stroke diagnosed?

A: Posterior circulation stroke is diagnosed using a combination of:

Imaging tests: Imaging tests such as CT or MRI scans can help diagnose posterior circulation stroke.
Physical examination: A physical examination can help identify symptoms and signs of posterior circulation stroke.
Laboratory tests: Laboratory tests such as blood tests and electrocardiograms can help diagnose underlying conditions that may contribute to posterior circulation stroke.

Q: What is the treatment for posterior circulation stroke?

A: The treatment for posterior circulation stroke depends on the severity of the stroke and the patient's overall health status. Treatment may include:

Medications: Medications such as anticoagulants and antiplatelet agents can help prevent further stroke.
Surgery: Surgery may be necessary to remove blood clots or repair damaged blood vessels.
Rehabilitation: Rehabilitation can help patients recover from posterior circulation stroke and improve their quality of life.

Q: Can posterior circulation stroke be prevented?

A: Yes, posterior circulation stroke can be prevented by:

Managing risk factors: Managing risk factors such as hypertension, diabetes, and smoking can help prevent posterior circulation stroke.
Maintaining a healthy lifestyle: Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help prevent posterior circulation stroke.
Getting regular check-ups: Getting regular check-ups with a healthcare provider can help identify underlying conditions that may contribute to posterior circulation stroke.

Q: What is the prognosis for patients with posterior circulation stroke?

A: The prognosis for patients with posterior circulation stroke depends on the severity of the stroke and the patient's overall health status. Patients who receive prompt and effective treatment may have a better prognosis and improved quality of life.
