ABSTRACT
Objective To investigate the clinical characteristics of patients with cryptogenic stroke and patent foramen ovale (PFO). Methods The clinical features, imaging findings and therapeutic outcomes of 51 patients with cryptogenic stroke and PFO, who received treatment in Stroke Center of Changhai Hospital of Navy Medical University (Second Military Medical University) between Sep. 2013 and Jan. 2018, were retrospectively analyzed. Results Of the 51 cases, 41 were male and 10 were female; and the mean age was (53.92±14.83) years (ranging from 21 to 84 years). Diffusion weighted imaging (DWI) showed that 46 patients developed new infarction including 20 cases (43.5%) of single lesion and 26 cases (56.5%) of multiple lesions, of which 15 cases (57.7%) involved single arterial territory and 11 cases (42.3%) involved two or more arterial territories (4 cases of bilateral anterior circulation, and 7 cases of both the anterior and posterior circulations). Thirty-seven patients underwent contrast-enhanced transcranial Doppler (cTCD) examination, which showed that 31 cases (83.8%) had microbubble sign (air microbubble emboli of 4 cases looked like raindrops or curtains). In 50 patients undergoing transesophageal echocardiography (TEE) examination, 49 cases (98.0%) were accompanied with PFO. Nine patients received intravenous thrombolysis. In secondary prevention, 18 patients received single antiplatelet therapy, 12 dual antiplatelet therapy, 8 anticoagulation therapy, and 13 PFO closure+single antiplatelet therapy. One patient with single antiplatelet therapy had recurrent ischemic stroke, 2 patients with dual antiplatelet therapy had recurrent ischemic stroke, and the patients with percutaneous closure of PFO had no recurrent stroke. Conclusion The infarction of cryptogenic stroke with PFO involves single or multiple arterial territories, cTCD and TEE have high positive diagnosis rate for PFO, and the patients with selective antithrombotic therapy and PFO closure have a low risk of recurrent stroke.
