Description
Summary:To date, this is the first case of a paradoxical embolism (PDE) that concurrently manifested in the coronary and lower limb arteries and was secondary to a central venous catheter (CVC) thrombus a patent foramen ovale (PFO). Here, we report a case of simultaneous coronary and lower limb artery embolism in a PFO patient carrier of a CVC. The patient presented to the hospital with acute chest pain and lower limb fatigue. Doppler ultrasound showed a large thrombus in the right internal jugular vein, precisely at the tip of the CVC. Transthoracic and transesophageal echocardiography confirmed the existence of a PFO, with inducible right-to-left shunting by the Valsalva maneuver. The patient was administered an extended course of anticoagulation therapy, and then the CVC was successfully removed. Percutaneous PFO closure was not undertaken. There was no recurrence during follow-up. Thus, CVC-associated thrombosis is a potential source for multiple PDE in PFO patients.
