Abstract:
Background: Pulmonary embolism (PE) remains a significant cause of mortality in Europe1. Thrombolytic therapy is often utilised as a therapeutic strategy in massive and sub-massive PE. There is a dearth of research on short term complications and subsequent outcomes in patients who have received thrombolysis for PE in Ireland. Methods: This retrospective study examined patients who underwent thrombolysis for acute sub massive PE whilst under the care of the respiratory service in Cork University Hospital (CUH) from 2010-2018. All patients had CTPA done for diagnosis of PE. Alteplase was used as a thrombolytic agent. Patient records were perused. Follow-up pulmonary functions tests (PFTs) and trans-thoracic echocardiogram (TTE) results were assessed for evidence of impairment of diffusing capacity (DLCO) and pulmonary hypertension (PH) respectively. Results: Twenty five patients were included in the study. Nine patients (36%) were women and 64% men. Average age was 55.1 years. Four patients suffered complications related to thrombolysis (average age 63.3 years). Twenty-Two patients (88%) underwent a follow-up echocardiography (mean 30 weeks post PE). Three patients (13%) had echocardiographic evidence of possible mild PH (i.e. RVSP >40mmhg) at initial follow-up. Fourteen patients (56%) who underwent thrombolysis had follow-up PFTs (mean 11.8 months post PE). The diffusing capacity (DLCO) was normal in all patients. Conclusion: Thrombolysis was a relatively safe intervention in this small study.
