Wrong endpoints measured. Survivors don't give a shit about;
groin puncture time
reperfusion time
first pass effect
number of passes
Didn't even measure how close to 100% recovery survivors got.
Effect of balloon guide catheter on clinical outcomes and reperfusion in Trevo thrombectomy
Abstract
Introduction
The Solitaire stent retriever registry showed improved reperfusion,
faster procedure times, and better outcome in acute stroke patients with
large vessel occlusion treated with a balloon guide catheter (BGC) and
Solitaire stent retriever compared with a conventional guide catheter.
The goal of this study was to evaluate whether use of a BGC with the
Trevo stent retriever improves outcomes compared with a conventional
guide catheter.
Methods
The TRACK registry recruited 23 sites to submit demographic, clinical,
and site adjudicated angiographic and outcome data on consecutive
patients treated with the Trevo stent retriever. BGC use was at the
discretion of the physician.
Results
536 anterior circulation patients (of whom 279 (52.1%) had BGC
placement) were included in this analysis. Baseline characteristics were
notable for younger patients in the BGC group (65.4±15.3 vs 68.1±13.6,
P=0.03) and lower rate of hypertension (72% vs 79%, P=0.06). Mean time
from symptom onset to groin puncture was longer in the BGC group (357 vs
319 min, P=0.06).Thrombolysis in Cerebral Infarction 2b/3 scores were
higher in the BGC cohort (84% vs 75.5%, P=0.01). There was no difference
in reperfusion time, first pass effect, number of passes, or rescue
therapy. Good clinical outcome(What the fuck is your definition of this? Mine is 100% recovery.) at 3 months was superior in patients with
BGC (57% vs 40%; P=0.0004) with a lower mortality rate (13% vs 23%,
P=0.008). Multivariate analysis demonstrated that BGC use was an
independent predictor of good clinical outcome (OR 2; 95% CI 1.3 to 3.1,
P=0.001).
Conclusions
In acute stroke patients presenting with anterior circulation large
vessel occlusion, use of a BGC with the Trevo stent retriever resulted
in improved reperfusion, improved clinical outcome, and lower mortality.
