Abstract:
Objective:To investigate the mid-term efficacy of Pulsar-18 stent in the treatment of spontaneous isolated superior mesen-teric artery dissection(SIDSMA)through a retrospective analysis.Methods:A retrospective analysis was performed for the data of pa-tients with SIDSMA who received treatment with Pulsar-18 stent from April 2019 to March 2021.Basic information was collected,such as sex,age,underlying disease,and radiological features,and the patients were observed in terms of the improvement in clinical symp-toms,stent patency rate,and vascular remodeling during follow-up.Results:A total of 45 patients were included in this study,with 41 male patients and 4 female patients.The patients had an age of 45-72 years,and the patients with hypertension accounted for 48.89%(22/45).The surgical success rate was 100%.A total of 63 stents were placed for the 45 patients,with a stent diameter ranging from 5 mm to 7 mm.There were no perioperative complications such as acute thrombosis of the stent,and the probability of hematoma at the puncture point was 0%.The stent patency rate was 100%at 3 months,6 months,1 year,and 2 years after stent placement,and the com-plete vascular remodeling rate was 64.4%,82.2%,82.2%,and 86.7%,respectively.One patient developed bloody stool at 5 months af-ter surgery and was diagnosed with duodenal ulcer,and the patient fully recovered after endoscopic hemostasis.The other patients had no recurrent abdominal pain,new-onset aneurysms,or enlargement of the false lumen within 2 years.Conclusion:Pulsar-18 stent placement is an effective treatment method for SIDSMA and can provide a high rate of complete vascular remodeling,with a high pa-tency rate during mid-term follow-up.
