Understanding the Aneurysm Rupture Score Calculator (PHASES)

The Aneurysm Rupture Score Calculator, also known as PHASES, is a predictive tool designed to assist healthcare professionals in estimating the risk of rupture for intracranial aneurysms over a 5-year period. Developed from a comprehensive analysis of patient data across six major international studies, the PHASES score incorporates six key factors: Population, Hypertension, Age, Size of aneurysm, Earlier subarachnoid hemorrhage from another aneurysm, and Site of the aneurysm. By inputting these parameters, the calculator outputs a score that corresponds to a percentage risk of rupture. For example, a patient with a small anterior circulation aneurysm, no history of hypertension or previous hemorrhage, under 70 years of age, and living in a region with a low incidence of aneurysms might receive a low PHASES score, indicating a relatively low risk of rupture over the next five years.

Main Functions of the Aneurysm Rupture Score Calculator (PHASES)

  • Risk Estimation

    Example Example

    A 55-year-old patient with a 7mm aneurysm in the posterior circulation, with hypertension, living in Europe.

    Example Scenario

    Using PHASES, a clinician inputs these details to calculate the aneurysm's 5-year rupture risk, aiding in decision-making about monitoring or intervention.

  • Comparative Analysis

    Example Example

    Comparing risks between a 40mm aneurysm in the anterior circulation without hypertension to a smaller aneurysm in a patient with hypertension.

    Example Scenario

    PHASES helps in evaluating the impact of different factors on rupture risk, supporting tailored patient counseling and management strategies.

  • Educational Tool

    Example Example

    Medical students or residents learning about risk factors for aneurysm rupture.

    Example Scenario

    PHASES serves as a practical learning tool, enhancing understanding of how various factors influence aneurysm rupture risk.

FAQs About the Aneurysm Rupture Score Calculator (PHASES)

  • What is the PHASES score?

    The PHASES score is a risk assessment tool that estimates the 5-year risk of rupture for intracranial aneurysms based on six parameters: population, hypertension, age, size of aneurysm, earlier subarachnoid hemorrhage from another aneurysm, and site of the aneurysm.

  • Who should use the PHASES calculator?

    It is designed for use by healthcare professionals, including neurologists, neurosurgeons, and radiologists, to inform clinical decision-making regarding the monitoring and treatment of brain aneurysms.

  • Can the PHASES score predict aneurysm rupture accurately?

    While the PHASES score provides an evidence-based estimate of rupture risk, it is important to use it in conjunction with clinical judgment and patient-specific considerations for optimal decision-making.

  • Is the calculator easy to use for non-specialists?

    The tool is designed to be user-friendly, but accurate input and interpretation of results require some understanding of the underlying medical concepts, making it more suitable for healthcare professionals.

  • How often should the PHASES score be recalculated for a patient?

    The score should be recalculated if there are significant changes in the aneurysm's size, patient's health status, or when new clinical evidence becomes available that could affect risk assessment.
