False aneurysm following blunt trauma.

T Mikulin, E W Walker

    Injury
    |March 1, 1984
    PubMed
    Summary

    False aneurysms after closed injury are often missed due to large hematomas masking pulsations. Increased awareness can prevent disastrous surgical interventions in emergency settings.

    Area of Science:

    • Traumatology
    • Vascular Surgery
    • Diagnostic Imaging

    Background:

    • Closed injuries can lead to delayed complications, including vascular injuries.
    • False aneurysms (pseudoaneurysms) are contained arterial ruptures, often presenting subtly.
    • Accurate diagnosis of post-traumatic vascular lesions is crucial for effective management.

    Observation:

    • Three patients presented with false aneurysms following seemingly minor closed injuries.
    • Initial clinical presentation was dominated by large hematomas, obscuring the underlying aneurysm.
    • Pulsations of the false aneurysm were not readily apparent due to the hematoma.
    • Diagnosis was delayed in all cases, leading to suboptimal initial management.

    Findings:

    • Large hematomas following closed injury can effectively mask underlying false aneurysms.
    • The absence of palpable pulsations does not rule out a false aneurysm in the presence of significant hematoma.
    • Delayed diagnosis can lead to inappropriate initial surgical interventions, such as simple incision and drainage.

    Implications:

    • Clinicians must maintain a high index of suspicion for false aneurysms in patients with significant hematomas after closed injury.
    • Diagnostic imaging, such as ultrasound or CT angiography, should be considered in suspected cases.
    • Improved awareness and diagnostic protocols can prevent iatrogenic complications and improve patient outcomes.
    • Early and accurate diagnosis of false aneurysms is essential to guide appropriate surgical or interventional management.
