【摘要】：目的评价不同CTA扫描方案显示旋股外侧动脉(LCFA)穿支的能力。方法将28例除大腿以外的四肢外伤患者及27名健康志愿者随机分为3组。对A组(15人,30侧大腿)采用双侧大腿低放射剂量扫描方案,B组(15人,30侧大腿)采用双侧大腿常规放射剂量扫描方案,C组(25人,25侧大腿)采用单侧大腿常规放射剂量扫描方案进行CTA检查。记录辐射吸收剂量,观察LCFA显示情况及起源,测量LCFA主干开口内径、降支开口内径、降支长度、降支血管分级、降支穿支数量、穿支末端最小内径。结果 B组中1例(2侧大腿)因对比剂渗漏未能完成检查。3组共83侧大腿,LCFA起自股动脉分别为A组7侧、B组8侧、C组6侧,起自股深动脉分别为A组23侧、B组20侧、C组19侧。3组间,辐射吸收剂量、降支长度、降支穿支末端最小内径、降支血管分级及降支穿支数量差异均有统计学意义(P均0.001),LCFA主干及降支开口内径差异均无统计学意义(P均0.05)。结论单侧大腿常规放射剂量CTA显示LCFA细小穿支的能力优于双侧低放射剂量及双侧常规剂量CTA,而3种扫描方案对较大血管的显示效果相近。
[Abstract]:Objective to evaluate CTA scan showed the lateral femoral circumflex artery perforator (LCFA). Methods 28 patients with limb trauma in the thigh outside and 27 healthy volunteers were randomly divided into 3 groups. Group A (15 people, 30 lateral thigh) with bilateral thigh low radiation dose scanning scheme, B group (15 30, lateral thigh) by bilateral thigh conventional radiation dose scanning scheme, C group (25 people, 25 lateral thigh) were examined by CTA with unilateral thigh conventional radiation dose scan scheme. Records of radiation absorbed dose, observe the display of LCFA and origin, measuring LCFA trunk opening diameter, descending opening diameter, descending length. Descending artery grading perforating descending branch number, minimum diameter. The terminal perforator B group 1 patients (2 lateral thigh) by contrast agent leakage check failed to complete the.3 group of 83 lateral thigh, LCFA from femoral artery were A group B group 7 side, 8 side, 6 side group C, since the deep femoral artery respectively. A group B group 23 side, 20 side, 19 side C group.3 group, radiation dose, descending length, perforating descending branch end of minimum diameter, descending vascular grading and descending perforating arteries volume differences were statistically significant (P 0.001), LCFA trunk and descending opening diameter and there were no statistical differences the significance (P < 0.05). Conclusion the unilateral thigh conventional radiation dose of CTA showed that LCFA small perforator is better than that of bilateral low radiation dose and conventional dose of bilateral CTA, and 3 kinds of scanning scheme shows the effect of large blood vessels are similar.
