Abstract:
Objective: To compare the radiation dose of direct aspiration first-pass thrombectomy (ADAPT) and conventional stent thrombectomy in treatment of acute middle cerebral artery occlusion. Methods: Totally 54 middle cerebral artery occlusion patients were retrospectively analyzed. The patients were divided into ADAPT group (n=29) and stent group (conventional stent removal, n=25) according to interventional treatment method. The intraoperative fluoroscopy time, air kerma (AK), dose area product (DAP), the number of photographic sequences and photographic frames were recorded and compared between 2 groups, and the correlations of the above indicators were analyzed. Results: The fluoroscopy time, AK, DAP, the number of photographic sequences and photographic frames in ADAPT group were all lower than those in stent group (all P<0.05). There were 25 cases (25/29, 86.21%) in ADAPT group and 13 cases (13/25, 52.00%) in stent group AK value <1.0 Gy, and the rate of patients with DAP value <1.0 Gy in ADAPT group was higher than that in stent group (P<0.01). There were 22 cases (22/29, 75.86%) in ADAPT group and 11 cases (11/25, 44.00%) in stent group DAP value <100 Gy•cm2, and the rate of patients with DAP value <100 Gy•cm2 in ADAPT group was higher than that in stent group (P=0.01). The fluoroscopy time was positively correlated with DAP (r=0.60, P<0.01) and AK (r=0.69, P<0.01), so was DAP and AK (r=0.81, P<0.01). Conclusion: The radiation dose of ADAPT technology was lower than conventional stent removal for treatment of acute middle cerebral artery occlusion.
