Abstract

Aim of study. We investigated the effectiveness and safety of an antegrade approach consisting of emergency ICA stenting in conjunction with mechanical thrombectomy (MT) in a one-stage procedure as a treatment for Tandem Occlusion (TO).

Clinical rationale for study. We here describe our experience in the treatment of TO with an antegrade approach with long-term results. We also discuss the advantages and drawbacks of this treatment modality with special attention to possible haemorrhagic complications that can be encountered in patients with ischaemic stroke who receive antiplatelet treatment. We believe that our study adds to the limited number of reports on this topic.

Materials and methods. We selected 34 patients diagnosed with acute ischaemic stroke due to ICA and ipsilateral intracranial occlusion treated with ICA stenting in conjunction with MT. We analysed the short- and long-term results as well as investigating complications with special regard to haemorrhagic transformation
associated with the need for antiplatelet treatment after stent implantation in patients after acute ischaemic stroke treatment.

Results. A favourable angiographic outcome was defined as mTICI 2b–3. This was achieved in 33/34 patients (97%). On average, NIHSS at 24 hours after the procedure was 8.5 ± 7, which indicates a significant clinical improvement. Four cases of symptomatic ICH were observed (11.8%). One re-occlusion in stent was noted. At three-month follow-up, mRS scores were 0 in 11 (34.3%), 1 in 5 (16%), 2 in 1 (3%), 3 in 3 (9.3%), 4 in 3 (9.3%), and 5 in 2 (6%) patients. Seven patients did not survive (22%). Overall, a favourable outcome (mRS 0–2) was achieved in 17/34 patients (50%). The final mortality rate was 26.5% (9/34 patients).

Conclusions and clinical implications. We conclude that an antegrade approach is a feasible and effective method for treating acute TO stroke, giving the patient the chance to regain his or her full independence in everyday life, with low overall complication and final mortality rates.
