A vascular shunt frame with improved apposition including a main body tube； at least one end of the main body tube is provided with a sealing covering； the sealing covering is provided with a main blood flow opening； a shaping component is disposed at the edge of the main blood flow opening. When the main body stent is inserted into the main blood flow opening of the main body tube, the shaping component can be closely attached to the outer surface of the main body stent, such that the sealing covering closely fits the outer surface of the main body stent to prevent endoleaks. The present disclosure also provides a vascular stent provided with an apposition-improved vascular shunt frame.
