ObjectiveTo study the clinical safety and effectiveness of paclitaxel-drug coated balloon (DCB) in treatment of Takayasu’s arteritis (TA) of renal artery. MethodsThe 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. ResultsSuccessful 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. ConclusionPaclitaxel-DCB is safe and effective for patients with renal artery stenosis of TA, but further researches with large sample are still needed.
The cultivation of clinical medical postgraduates is a way to provide qualified doctors for clinical practice, which is more focused on clinical practice. The cultivation of clinical medical postgraduates depends on their understanding of knowledge. In response to the problems existing in traditional education, the Department of Vascular Surgery, Xuanwu Hospital, Capital Medical University has introduced new media into the cultivation of clinical medical postgraduates. New media can concretize abstract content, which is more conducive to improve learning efficiency. This article combines practical experience to explain the advantages, teaching effectiveness, challenges faced of new media, and how to better apply new media teaching.
ObjectiveTo evaluate efficacy and safety of treatment of Kommerell diverticulum with endovascular technique.MethodThe retrospective analysis was made on the preoperative clinical data, surgical treatment, and postoperative status of patient with Kommerell diverticulum who underwent the endovascular treatment in the Department of Vascular Surgery, Xuanwu Hospital of Capital Medical University.ResultsAccording to the different types and clinical symptoms, the effective endovascular treatment was adopted. The thoracic endovascular aortic repair and coil embolization of Kommerell diverticulum were successfully performed. The postoperative aortic blood flow was unobstructed and the aneurysmal lesion was completely isolated. No endoleakage and intracranial and upper limb ischemia were occurred. The operation time was 55 min and the blood loss was 20 mL. The patient was discharged on day 6 after the operation. No endoleakage, dizziness, and upper limb numbness were found following-up for 12 months.ConclusionFor patient with different types of Kommerell diverticulum and different symptoms, who could be treated by appropriate endovascular treatment and it is effective and safety.
