Insights
Emergent revascularisation for acute internal carotid artery (ICA) occlusion is a feasible treatment for acute ischemic stroke. This procedure, utilizing advanced diagnostics, shows promising results with low complication rates.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Neuroradiology
Context:
- Acute ischemic stroke due to internal carotid artery (ICA) occlusion presents a critical neurovascular emergency.
- Timely intervention is crucial to restore blood flow and prevent irreversible brain damage.
- Current diagnostic modalities and revascularization techniques are continuously evolving.
Purpose:
- To evaluate the indications and outcomes of emergent revascularization for acute extracranial ICA occlusion.
- To assess the feasibility, safety, and efficacy of current diagnostic methods in identifying suitable candidates.
- To analyze the success rates, clinical improvement, and complication profile of the intervention.
Summary:
- A prospective study followed 34 patients undergoing emergency revascularization for acute extracranial ICA occlusion within 72 hours of symptom onset.
- Diagnostic workup included duplex sonography, CT/MRI, and angiography (MRA/DSA).
- Revascularization via endarterectomy and thrombectomy was successful in 88% of cases, with 59% showing clinical improvement and a 30-day mortality of 6%.
Impact:
- Emergent revascularization of acute extracranial ICA occlusion is a viable treatment option.
- Careful patient selection and advanced diagnostic imaging are key to successful outcomes.
- The procedure demonstrates a favorable risk-benefit profile, offering potential for neurological recovery.
Background And Purpose:
We examined indications for emergent revascularisation of acutely occluded internal carotid artery (ICA) using current diagnostic methods.
Material And Methods:
From 1997 to 2006 we prospectively followed 34 consecutive patients undergoing emergency revascularisation due to acute extracranial ICA occlusion and acute ischaemic stroke within 72 h after symptom onset (mean 25) and within 36 h after admission (mean 16). Exclusion criteria were occlusion of the intracranial ICA or ipsilateral middle cerebral artery (MCA), ischaemic infarction of more than one third of the MCA perfusion area, or reduced level of consciousness. All patients underwent duplex sonography, cerebral CT, and/or MRI and angiography (MRA and/or DSA). We performed endarterectomy and thrombectomy of the ICA.
Results:
Confirmed by postoperative duplex sonography at discharge, ICA revascularisation was successful in 30 (88%) of 34 cases. Postoperative intracranial haemorrhage was detected in two patients (6%) and perioperative reinfarction in one (3%). Compared to the preoperative status, 20 patients (59%) showed signs of clinical improvement by at least one point on the Rankin scale, ten patients (29%) remained stable, and two patients (6%) had deteriorated. The 30-day mortality was 6% (two patients).
Conclusion:
After careful diagnostic workup, revascularisation of acute extracranial ICA occlusion is feasible with low morbidity and mortality.
