Abstract
OBJECTIVES
Studies on the short-, medium and long-term effects of flow guiding stents are still limited. In this case report, we present three-year follow-up of the multilayer flow modulator stent in a 55-year-old patient with Crawford Type 2 thoracoabdominal aortic aneurysm.
METHODS
A 55-year-old male patient with Crawford Type 2 thoracoabdominal aortic aneurysm had applied to our medical center. The aneurysm involved coeliac truncus and superior mesenteric artery and extended to the renal artery ostia. Multilayer flow modulator stent was successfully placed, and follow-up CT (Computed tomography) angiographic examination images recorded intermittently (36 months).
RESULTS
After three years, it was observed that the left renal artery was thrombosed and the left kidney went to atrophy. Other major vascular branches were observed to be open. During this time, the aneurysm was completely closed with thrombus, but the diameter of the aneurysm continued to increase.
CONCLUSIONS
Multilayer flow modulator stents are safe in complex aortic aneurysms. The device increases the thrombus load in the aortic aneurysm and maintains the flow of the main vascular branches. But re-interventions, dilatation of the aneurysm sac and visceral branch obstructions are still challenging for multilayer flow modulator stents.
