Anticoagulant treatment for pulmonary embolism in patient with cerebral hemorrhage secondary to mechanical thrombectomy: A case report

Figure 1 MRI and digital subtraction angiography imaging before and after surgery. A: Axial brain MRI (DWI) on admission showed acute cerebral infarction in the basal ganglia; B: Postoperative brain MRI (DWI) showed subacute large areas of cerebral infarction with basal ganglia hemorrhage; C: Angiogram of the left internal carotid artery showed proximal occlusion of the left middle cerebral artery before mechanical thrombectomy; D: Postoperative angiography showed complete recanalization of the left internal carotid artery and middle cerebral artery. DWI: Diffusion-weighted imaging; MRI: Magnetic resonance imaging.

Figure 2 Changes in pulmonary embolism before and after anticoagulation. A, C: Pulmonary angiogram showed multiple repletion defects in both the pulmonary artery trunks and its branches before anticoagulation; B, D: Pulmonary angiogram showed the thrombus was eliminated after 20 d of treatment.

Figure 3 Changes on brain CT scan after surgery. A: Postprocedural brain CT showed large areas of cerebral infarction and hemorrhage in the left basal ganglia area; B–D: Follow-up brain CT showed no new evidence of cerebral infarction or hemorrhage. CT: computed tomography.
