Is an Antiplatelet Treatment required after an Endovascular covered stent placement for Treatment of Iatrogenically Injured non diseased Arteries?

The patient was a 50-year-old female who had past medical history of hemiglossectomy for squamous cell carcinoma of tongue and recent diagnosis of lung metastasis now presented to emergency department with respiratory failure and sepsis. During resuscitation, CVC was erroneously placed into a R-CCA. CT scan of the neck revealed a CVC entering from right side of the neck then coursing directly into the R-CCA lumen. Patient was urgently taken to IR suite. Selective angiography demonstrated patent R-CCA without any extravasation and 7 Fr CVC entering into the lumen of R-CCA and then coursing into the aortic arch. Under fluoroscopy guidance, as the CVC was slowly being retracted over a wire, a 7 mm x 2.5 cm heparin bonded Viabahn covered stent was deployed to seal the defect in the R-CCA. The stent was then inflated with same size 7 mm balloon without exerting any stretch on the vessel wall. Completion angiography demonstrated patent R-CCA without any evidence of extravasation. Based on prior CT scans, patient did not have any atherosclerotic disease in the cardiovascular system. After carotid artery stenting, patient was placed on antiplatelet medication regimen with an intention to prevent a stent thrombosis as per the common clinical practices. However, we would like to question the need for any antiplatelet treatment after an endovascular stent placement for the treatment of iatrogenically injured non-atherosclerotic disease-free vessel.
