IVT was administered despite guideline recommendations in a case of intracranial arterial dissection with associated thrombus, leading to rapid clinical improvement and normalization of neurological function within 24 hours, suggesting that individualized treatment approaches may be warranted in select cases.
A 34-year-old male with intracranial vertebral artery dissection received IVT despite guideline recommendations against its use in this setting.
IVT administration resulted in rapid clinical improvement and normalization of neurological function within 24 hours.
Subsequent MRI confirmed the diagnosis of left V4 artery dissection and demonstrated evolution of the mural hematoma over time.
The case highlights that the spontaneous hyperdense appearance on NCCT can serve as an early imaging sign for intracranial arterial dissection.
The authors conclude that individualized treatment approaches may be warranted in patients with intracranial dissections presenting as ischemic stroke, and that rigid application of current guidelines may not be appropriate in all cases.
This research presents a single case report of a 34-year-old man who had a type of stroke caused by a tear in the inner wall of an artery at the base of the brain (intracranial arterial dissection), which also had a blood clot associated with it. Standard medical guidelines recommend against giving clot-dissolving medication (called intravenous thrombolysis or IVT) in this situation because of concerns that it could cause dangerous bleeding into the artery wall. However, because the patient's condition was worsening and imaging clearly showed the problem, doctors decided to administer the clot-dissolving treatment anyway. The patient recovered rapidly, with neurological function returning to normal within 24 hours, and follow-up brain scans confirmed the diagnosis and showed how the injury to the artery wall changed over time. This research suggests that the combination of different brain imaging techniques — including a standard CT scan, CT angiography, and MRI — was critical for accurately identifying this unusual type of stroke and guiding treatment decisions. The initial CT scan showed an unusual bright appearance along the affected artery, which raised early suspicion for the dissection before more detailed imaging was done. The authors argue that this case demonstrates that a one-size-fits-all approach based on current guidelines may not always be appropriate, and that in carefully selected patients, clot-dissolving therapy might be safe and effective even when a dissection is present. The practical implication of this single case is limited, as it involves only one patient, but it raises important questions about whether current treatment guidelines — which were developed partly out of caution due to limited data — might be too restrictive in some situations. The authors call for larger, dedicated studies to better understand when IVT might be safely used in patients with intracranial dissection, so that future guidelines can be based on stronger evidence and treatment decisions can be better tailored to individual patients.
