Mechanical thrombectomy (MT) is usually performed on biplane (BP) angiosuites. When the BP angiosuite is not available, the single-plane (SP) angiosuite may be a substitute. However, the feasibility of MT performed on the SP angiosuite is yet to be elucidated. Therefore, we investigated the alternative effect of the SP angiosuite on the detailed division of procedure time, recanalization rate, and outcome in patients with anterior circulation infarction.
The subjects included 80 consecutive patients with anterior circulation infarction who underwent MT at our hospital between May 2015 and December 2020. Demographics and characteristics of the BP and SP groups were assessed and compared. The time from puncture to guiding catheter placement (P-G), time from guiding catheter placement to recanalization (G-R), and time from puncture to recanalization (P-R) were also extracted. A good outcome was defined as a modified Rankin scale score ≤2 at 3 months.
Of the 80 patients, 67 and 13 were treated with BP and SP angiosuites, respectively. There were no differences in age, sex, complications, Alberta Stroke Program Early CT Score, National Institutes of Health Stroke Scale score at onset, occlusion site, rate of recombinant tissue-type plasminogen activator administration, stroke subtype, recanalization rate, and complications between the 2 groups. The rate of a good outcome was not different between the 2 groups. P-G was significantly longer in the SP group than in the BP group, whereas there was no significant difference in G-R and P-R between the 2 groups (P-G: BP 29.9 ± 21.8 vs. SP 48.5 ± 43.6 min, p = 0.04).
MT performed on the SP angiosuite tended to prolong the time for guiding catheter placement. However, there was no difference in the overall procedure time, recanalization rate, or outcome between BP and SP angiosuites. Therefore, if the BP angiosuite is not available, the use of the SP angiosuite should be encouraged.
机械血栓切除术（MT）通常在双平面（BP）血管套件上进行。当 BP 血管套件不可用时，单平面（SP）血管套件可能是替代方案。然而，MT 在 SP 血管套件上的可行性尚不清楚。因此，我们研究了 SP 血管套件对前循环梗死患者详细手术时间划分、再通率和结果的替代效果。
纳入 2015 年 5 月至 2020 年 12 月在我院接受 MT 的 80 例前循环梗死患者。评估和比较 BP 和 SP 组的人口统计学和特征。提取从穿刺到导引导管放置（P-G）、从导引导管放置到再通（G-R）和从穿刺到再通（P-R）的时间。良好的结果定义为 3 个月时改良 Rankin 量表评分≤2。
80 例患者中，67 例和 13 例分别采用 BP 和 SP 血管套件治疗。两组在年龄、性别、并发症、阿尔伯塔卒中计划早期 CT 评分、发病时美国国立卫生研究院卒中量表评分、闭塞部位、重组组织型纤溶酶原激活剂使用率、卒中亚型、再通率和并发症方面无差异。两组间良好结局的发生率无差异。SP 组 P-G 明显长于 BP 组，而两组 G-R 和 P-R 无差异（P-G：BP 29.9±21.8 与 SP 48.5±43.6 min，p=0.04）。
SP 血管套件上的 MT 操作往往会延长导引导管放置时间。然而，BP 和 SP 血管套件在总手术时间、再通率和结果方面无差异。因此，如果 BP 血管套件不可用，应鼓励使用 SP 血管套件。
