Application of drug coated balloon in treatment of Takayasu's arteritis of renal artery
Objective To study the clinical safety and effectiveness of paclitaxel-drug coated balloon(DCB)in treatment of Takayasu's arteritis(TA)of renal artery.Methods The retrospective analysis was made on the clinical data of the three patients with severe stenosis of renal artery,who were treated in our hospital from January 2019 to August 2023.The patients underwent paclitaxel-DCB dilation therapy.Results Successful treatment was accomplished in all the three patients.The patients were followed up for 17,38,and 40 months respectively,follow-up examination of ultrasound showed that the blood flow in renal artery was unobstructed.The serum creatinine level was changed from preoperative 53,64,55 μmol/L to 43,70,59 μmol/L on postoperative day 1.The systolic blood pressure was decreased from preoperative 180,220,150 mmHg to 116,120,110 mmHg on postoperative day 1.The peak systolic velocity of renal artery was reduced from preoperative 350,377,293 cm/s to 120,135,94 cm/s on postoperative day 1.Conclusion Paclitaxel-DCB is safe and effective for patients with renal artery stenosis of TA,but further researches with large sample are still needed.
