Aquilla Turk, from the department of Radiology, MUSC, Charleston, USA, presented a case showing how well a technique works that uses a direct aspiration first pass with a large bore aspiration catheter as the primary method for vessel recanalisation at the fifth European Society of Minimally Invasive Neurological Therapy (ESMINT) congress (5–7 September, Nice, France).
“Using the latest generation of large bore aspiration catheters in this fashion has allowed us to achieve excellent clinical and angiographic outcomes,” he told delegates. He previously presented the preliminary results of the technique at the Society of NeuroInterventional Surgery (SNIS) 10th annual meeting in Miami, USA.
Turk and colleagues carried out a retrospective evaluation of a prospectively captured database of 37 patients at six institution in whom the ADAPT technique was used.
- The ADAPT technique used on its own was successful in 28 of 37 (75%) cases.
- There were four cases that had large downstream emboli requiring additional aspiration.
- Nine cases required the additional use of a stent retriever and one case required the addition of a Penumbra aspiration separator to achieve recanalisation.
- The average time from groin puncture to at least Thrombolysis in Cerebral Ischaemia (TICI) 2b recanalisation was half an hour.
- All cases were successfully revascularised.
- TICI 3 recanalisation was achieved 72% of the time.
- On average, patients presented with an admitting National Institutes of Health Stroke Scale (NIHSS) score of 16.4 and improved to an NIHSS score of 3.1 by the time of hospital discharge.
- There was one procedural complication.
