Low dose peripheral systemic thrombolysis for treatment of intermediate-high risk acute pulmonary embolism: a case series.

ABSTRACT:

Background

The management of intermediate-high-risk acute pulmonary embolism (PE) is controversial with increasing interest in more aggressive treatment approaches than anticoagulation alone.

Case summary

We describe the case series of four consecutive patients who presented to emergency room for acute shortness of breath. They were diagnosed with intermediate-high-risk acute PE based on the computed tomography pulmonary angiography and transthoracic echocardiography (TTE) findings and the elevated simplified PE score index. They received bolus of 5 mg thrombolytics recombinant tissue plasminogen activator (rtPA) administered through peripheral intravenous (i.v.) line followed by continuous infusion at a rate of 2 mg/h along with unfractionated heparin (UFH) at a rate of 500 mg/h for additional ≤10 h. There after the dose of UFH was increased to reach a therapeutic level. Rapid clinical improvement and also improvement in TTE parameters were noted at discharge. Patients were discharged home on oral anticoagulation.

Discussion

Intermediate-high-risk acute PE carries increased risk of mortality and morbidities. Catheter-directed thrombolysis uses a low rtPA dose for local thrombolysis and is associated with low bleeding risk; however it is expensive and requires expertise and human resources. Low-dose rtPA through a peripheral i.v. line might be safe and effective in the treatment of patient with intermediate-high-risk acute PE. This therapeutic approach is readily available at most medical centres, can be started in the emergency room (ER), and can be alternative to catheter-directed thrombolysis nowadays during the COVID-19 era and in hospitals at the periphery and with limited resources.

Project description:BackgroundTherapeutic options for intermediate- or high-risk pulmonary embolism (PE) include anticoagulation, systemic thrombolysis and catheter-directed thrombolysis (CDT); however, the role of CDT remains controversial. We sought to compare the efficacy and safety of CDT with other therapeutic options using network meta-analysis.MethodsWe searched PubMed (MEDLINE), Embase, ClinicalTrials.gov and Cochrane Library from inception to Oct. 18, 2022. We included randomized controlled trials and observational studies that compared therapeutic options for PE, including anticoagulation, systemic thrombolysis and CDT among patients with intermediate- or high-risk PE. The efficacy outcome was in-hospital death. Safety outcomes included major bleeding, intracerebral hemorrhage and minor bleeding.ResultsWe included data from 44 studies, representing 20 006 patients. Compared with systemic thrombolysis, CDT was associated with a decreased risk of death (odd ratio [OR] 0.43, 95% confidence interval [CI] 0.32-0.57), intracerebral hemorrhage (OR 0.44, 95% CI 0.29-0.64), major bleeding (OR 0.61, 95% CI 0.53-0.70) and blood transfusion (OR 0.46, 95% CI 0.28-0.77). However, no difference in minor bleeding was observed between the 2 therapeutic options (OR 1.11, 95% CI 0.66-1.87). Compared with anticoagulation, CDT was also associated with decreased risk of death (OR 0.36, 95% CI 0.25-0.52), with no increased risk of intracerebral hemorrhage (OR 1.33, 95% CI 0.63-2.79) or major bleeding (OR 1.24, 95% CI 0.88-1.75).InterpretationWith moderate certainty of evidence, the risk of death and major bleeding complications was lower with CDT than with systemic thrombolysis. Compared with anticoagulation, CDT was associated with a probable lower risk of death and a similar risk of intracerebral hemorrhage, with moderate certainty of evidence. Although these findings are largely based on observational data, CDT may be considered as a first-line therapy in patients with intermediate- or high-risk PE.Protocol registrationPROSPERO - CRD42020182163.

Project description:AimsData on the early course and use of systemic thrombolysis in pregnant women with pulmonary embolism associated or not with haemodynamic failure are scarce. We investigated these aspects using the information from the German Nationwide Inpatient Registry (years 2005-2016).Methods and resultsIn Germany, all diagnoses referring to hospitalized patients are coded according to the International Classification of Diseases and Related Health Problems, 10th Revision with German Modification. We analysed data of pregnant women aged 18-50 years for whom the following diagnoses were recorded during hospitalization: (i) pulmonary embolism (I26) during pregnancy or peripartum (O09) or (ii) obstetric thromboembolism (O88.2). Haemodynamic failure at any time during the in-hospital stay was defined as need for cardiopulmonary resuscitation (OPS code 8-77) or the presence of shock (International Classification of Diseases and Related Health Problems, 10th Revision with German Modification code R57). The primary study outcome was in-hospital death. A total of 8 271 327 births were registered in Germany from 2005 to 2016. During this 12 year time period, there were 1846 hospitalizations for pregnancy-associated pulmonary embolism in patients aged 18-50, corresponding to 2.2 [95% confidence interval (CI): 2.1-2.3] cases every 10 000 births and 0.2% of all hospitalizations for pulmonary embolism in Germany. The median age was 31 years, and the median length of hospitalization was 8 days. A total of 63 deaths were reported, corresponding to an overall in-hospital fatality rate of 3.4% (95% CI: 2.7-4.4) and a pulmonary embolism-related mortality rate of 0.8 (95% CI: 0.6-1.0) per 100 000 (live) births per year. Pulmonary embolism-related deaths in hospitalized pregnant women represented 14% of all maternal deaths recorded in Germany between 2005 and 2016. A total of 135 (7.3%) women had haemodynamic failure, of whom 51 (37.8%) received systemic thrombolysis and 50 (37.0%) died.ConclusionsPulmonary embolism-related fatality remains substantial in pregnant women with pulmonary embolism and represents a frequent cause of maternal mortality. The use of systemic thrombolysis was reported in one third of pregnant women with pulmonary embolism and haemodynamic failure. Better preventive and management strategies should be urgently implemented in this vulnerable patient group.
