Effect of Modified Tongqiao Huoxuetang on Circulating Blood Flow and Wall Shear Stress Due to Blood Stasis and Channel Blockage
To observe the effect of modified Tongqiao Huoxuetang on circulating blood flow and wall shear stress of vertebrobasilar dolichoectasia (VBD) due to blood stasis and channel blockage.
Method
2
A total of 97 patients admitted in our department from October 2017 to August 2019 were collected. The traditional Chinese medicine (TCM) syndromes were consistent with blood stasis and channel blockage
and diagnosed as VBD by magnetic resonance angiography (MRA). The patients were divided into experimental group (48 cases) and control group (49 cases). Control group was given basic therapy and placebo of TCM
while treatment group was given basic therapy and modified Tongqiao Huoxuetang for 30 days. The degree of relief of vertigo symptoms
and wall shear force (WSS) were observed before and after treatment.
Result
2
Compared with control group before treatment
the score of ABC scale in control group after treatment was markedly higher
while the score of VSS was significantly lower (
P
<
0.05). However
there was no statistical significance in the score of vertigo symptom. Compared with treatment group before treatment
the symptom grade of vertigo degree and the score of VSS in treatment group after treatment were substantially lower
while the score of ABC scale was significantly higher (
P
<
0.05). Compared with control group
the score of vertigo degree symptoms and VSS in treatment group were markedly lower
while the score of ABC scale was significantly higher (
P
<
0.05). Compared with control group before treatment
Vm
MFV and WSS of bilateral vertebral artery in control group after treatment were substantially higher
while RI was significantly lower (
P
<
0.05). However
there were no statistical significances in Vs
Vd and PI in control group before and after treatment. Compared with treatment group
Vs
Vd
Vm
MFV and WSS of bilateral vertebral artery in treatment group after treatment were markedly higher
while RI was significantly lower (
P
<
0.05). However
there was no statistical significance in PI of experimental group before and after treatment. Compared with control group after treatment
Vs
Vd
Vm
MFV and WSS of bilateral vertebral artery in treatment group after treatment were substantially higher
while there was no statistical significance in PI and RI. Before and after treatment
there were similar changes in blood flow parameters of the basilar artery and bilateral vertebral artery.
Conclusion
2
Modified Tongqiao Huoxuetang could improve the clinical symptoms of dizziness or vertigo in patients of VBD due to blood stasis and channel blockage
and the mechanism might be related to the improvement of post-circulation hemodynamics by Tongqiao Huoxuetang.
