Methods and materials
In this single-center retrospective study every patient with acute ischemic stroke of anterior circulation,
older than 80 years old,
undergoing mechanical thrombectomy between January 2015 and December 2017 was included.
They were a total of 60 patients.
We assessed demographic and clinical variables such as sex,
age,
cardiovascular risk factors (diabetes mellitus -DM-,
hypertension) or atrial fibrilation (AFib).
Acute neurological status was assessed using the National Institutes of Health Stroke Scale (NIHSS),
functional status using the modified Rankin Scale (mRS) (for assessment of baseline functional status and clinical outcome at 3 months) and recanalization using the modified Thrombolysis In Cerebral Infarction (mTICI) scale.
The recanalization rate and the functional status at 90 days were considered as efficacy variables.
For the analysis of the recanalization rate,
the modified Treatment In Cerebral Ischemia scale (mTICI) was used,
considering successful recanalization mTICI 2b or 3.
Moreover,
a modified Rankin scale at 90 days equal or less than 2 was considered a positive functional outcome.
Early symptomatic hemorrhagic transformation,
the 90-day mortality and the complications of the procedure were used as safety variables.
The hemorrhagic transformation was assessed according to the ECASS II classification,
considering the PH1 and PH2 as symptomatic complications.
Other several variables were also analyzed,
looking for significant differences: the side of the stroke,
the presence of tandem occlusion,
the Alberta Stroke Programme Early CT Score (ASPECTS), the number of passes of the procedure and the administration of intra-arterial thrombolysis.
