Method for determining the effectiveness of a medical therapy by analysis of collateral vessels |
摘要 |
In a method for determining the effectiveness of a therapy for alleviating a constriction in a blood vessel, the functioning of collateral vessels naturally formed at the constriction is analyzed. The analysis takes place by making a blood flow measurement at the vessel in which the constriction is present, or at a complementary vessel, with the patient experiencing two different stress conditions. The flow measurement can ensue by magnetic resonance or using ultrasound. Comparison of the stress-dependent blood flow to a reference is then undertaken to determine whether the collateral vessels are functioning effectively, and thus whether the treatment for alleviating the constriction is effective.
