目的:探讨单侧永存三叉动脉(PTA)患者发生近心段基底动脉发育不全(BAH)的影响因素。方法:横断面研究。纳入2021年1月—2023年12月在济宁医学院附属医院医学影像科行颅脑磁共振血管成像(MRA)检查的单侧Weon 1~4型PTA患者176例,其中男65例、女111例,年龄6~84(57.5±12.9)岁。患者均接受颅脑三维时间飞跃法MAR扫描,MRA图像使用容积重现、最大密度投影等技术进行图像后处理。观察指标:(1)PTA Salas分型和Weon分型情况;(2)测量PTA起始处及其汇入基底动脉处的直径、汇入点近心段和远心段基底动脉的直径,以及PTA汇入基底动脉处至小脑上动脉间的距离;(3)按照近心段基底动脉直径,将患者分为无BAH(non-BAH)组(近心段基底动脉直径≥2 mm)和BAH组(近心段基底动脉直径0.05)。BAH组的PTA汇入基底动脉处直径为(2.9±0.6)mm,大于non-BAH组的(2.5±0.6)mm;远心段基底动脉直径为(3.1±0.6)mm,小于non-BAH组的(3.4±0.5)mm;non-BAH组Weon分型1型65例、2型2例、3型16例、4型10例,BAH组Weon分型1型48例、2型12例、3型14例、4型9例:组间比较差异均有统计学意义(t=16.03、18.71,χ^(2)=9.35,P值均<0.05),单因素分析结果表明,PTA汇入基底动脉处直径、远心段基底动脉直径、Weon分型是发生近心段BAH的影响因素;多因素logistic回归分析结果显示,PTA汇入基底动脉处的直径增大、Weon 2型(相对于1型)是发生近心段BAH的危险因素[OR(95%CI)分别为15.75(6.26~39.63)、9.43(1.62~54.84)],远心段基底动脉直径增大是发生近心段BAH的保护因素[OR(95%CI)为0.08(0.03~0.20)]。对PTA汇入基底动脉处的直径与BAH发生率进行logistic曲线拟合发现,BAH的发生率与PTA汇入基底动脉处直径呈线性正相关。结论:PTA汇入基底动脉直径增大、Weon 2型(相对于1型)、远心段基底动脉直径增大是PTA患者发生近心段BAH的影响因素,其中,PTA汇入基底动脉处直径增大与近心段BAH的发生率呈线性正相关。

Objective: To evaluate the diagnostic value and safety of CT and ultrasound-guided PTNB for peripheral type of occupying lung lesions by meta-analysis and clinical study. Methods: 1) The target data of randomized controlled trials of CT and ultrasound-guided PTNB for peripheral type of occupying lung lesions were extracted by computer search of foreign PubMed, Embase, the Cochrane Library, Web of Science databases, since the establishment of the database. Cochrane quality assessment criteria were used for evaluation. Statistical analysis was performed using Review Manager 5.3 software. 2) To retrospectively study the diagnosis rate and complication rate of patients, undergoing CT or ultrasound-guided PTNB in the First Affiliated Hospital of Dali University from January 2015 to December 2020. Results: Meta-analysis included 7 papers with a total of 1177 patients including 502 patients in the ultrasound group and 675 patients in the CT group. Meta-analysis results showed that there was no difference in the diagnosis rate of PTNB guided by ultrasound and CT. The incidence of postoperative complications was higher in the CT group than in the ultrasound group. The incidence of postoperative pneumothorax was higher in the CT group than in the ultrasound group, and there was no difference in the incidence of postoperative bleeding. 3) Clinical study results show that the puncture success rate was 100% in both of the ultrasound and CT groups, the pathological diagnosis rate was 85.48% in the ultrasound group and 91.67% in the CT group, and there was no difference in the overall complication rate between the two puncture groups. Conclusion: Either ultrasound or CT-guided PTNB is a safe and effective clinical diagnostic method for the diagnosis of peripheral pulmonary occupations.
