Successful aspiration thrombectomy in a patient with submassive, intermediate-risk pulmonary embolism following COVID-19 pneumonia.

ABSTRACT: A 64-year-old female patient presented with severe dyspnea shortly after apparent recovery from COVID-19 disease. Chest computed tomography revealed central pulmonary embolism and ultrasonography showed a deep vein thrombosis of her right leg. The patient was tachycardiac with evidence of right ventricular strain on echocardiography. An interdisciplinary decision for interventional therapy was made. Angiographic aspiration thrombectomy resulted in a significant reduction of thrombus material and improved flow in the pulmonary arteries and immediate marked clinical improvement and subsequent normalization of functional echocardiographic parameters. This case adds to the emerging evidence for severe thromboembolic complications following COVID-19 and suggests aspiration thrombectomy can be considered in pulmonary embolism of intermediate risk.

Continuous Aspiration Thrombectomy in High- and Intermediate-High-Risk Pulmonary Embolism in Real-World Clinical Practice.

Project description:ObjectivesWe sought to assess the technical and clinical feasibility of continuous aspiration catheter-directed mechanical thrombectomy (CDT) in patients with high- or intermediate-high-risk pulmonary embolism (PE).Methods and resultsFourteen patients (eight women and six men; age range: 29-71 years) with high- or intermediate-high-risk PE and contraindications to or ineffective systemic thrombolysis were prospectively enrolled between October 2018 and February 2020. The Indigo Mechanical Thrombectomy System (Penumbra, Inc., Alameda, California) was used as CDT device. Low-dose local thrombolysis (alteplase, 3-12 mg) was additionally applied in three patients. Technical and procedural success was achieved in 14 patients (100%). Complete or nearly complete clearance of pulmonary arteries was achieved in nine patients (64.3%), whereas partial clearance was achieved in five (35.7%). A significant improvement in the pre- and postprocedural patients' clinical status was observed in the following fields (median; interquartile range): heart rate (110; 100-120/min vs. 85; 80-90/min; p < 0.0001), systolic blood pressure (106; 90-127 mmHg vs. 123; 110-133 mmHg; p = 0.049), arterial oxygen saturation (88.5; 84.2-93% vs. 95.0; 93.8-95%, p = 0.0051), pulmonary artery systolic pressure (55; 44-66 mmHg vs. 42; 34-53 mmHg; p = 0.0015), Miller index score (21.5; 20-23 vs. 9.5; 8-13; p < 0.0001) and right ventricular/left ventricular ratio (1.3; 1.3-1.5 vs. 1.0; 0.9-1.0; p < 0.0001). No major periprocedural bleeding was detected.ConclusionsCDT is a feasible and promising technique for management of high- or intermediate-high-risk PE to decrease thrombus burden, reduce right heart strain, and improve hemodynamic and clinical status. Some patients may benefit from simultaneous local low-dose thrombolytic therapy. Nevertheless, its criteria and role in CTD-managed patients require further elucidation.

Cardiopulmonary Exercise Testing in Patients Following Massive and Submassive Pulmonary Embolism.

Project description:BACKGROUND:Little data exist regarding the functional capacity of patients following acute pulmonary embolism. We sought to characterize the natural history of symptom burden, right ventricular (RV) structure and function, and exercise capacity among survivors of massive and submassive pulmonary embolism. METHODS AND RESULTS:Survivors of submassive or massive pulmonary embolism (n=20, age 57±13.3 years, 8/20 female) underwent clinical evaluation, transthoracic echocardiography, and cardiopulmonary exercise testing at 1 and 6 months following hospital discharge. At 1 month, 9/20 (45%) patients had New York Heart Association II or greater symptoms, 13/20 (65%) demonstrated either persistent RV dilation or systolic dysfunction, and 14/20 (70%) had objective exercise impairment as defined by a peak oxygen consumption (V?O2) of <80% of age-sex predicted maximal values (16.25 [13.4-20.98] mL/kg per minute). At 6 months, no appreciable improvements in symptom severity, RV structure or function, and peak V?O2 (17.45 [14.08-22.48] mL/kg per minute, P=NS) were observed. No patients demonstrated an exercise limitation attributable to either RV/pulmonary vascular coupling, as defined by a VE/VCO2 slope >33, or a pulmonary mechanical limit to exercise at either time point. Similarly, persistent RV dilation or dysfunction was not significantly related to symptom burden or peak V?O2 at either time point. CONCLUSIONS:Persistent symptoms, abnormalities of RV structure and function, and objective exercise limitation are common among survivors of massive and submassive pulmonary embolism. Functional impairment appears to be attributable to general deconditioning rather than intrinsic cardiopulmonary limitation, suggesting an important role for prescribed exercise rehabilitation as a means toward improved patient outcomes and quality of life.

Pulmonary embolism: Successful treatment of floating thrombus in SFJ after vena cava filter insertion and surgical thrombectomy.

Project description:The floating venous thrombus in the common femoral vein has a high potential risk for pulmonary embolization. Clinical treatments, using anticoagulants or fibrinolytic, open thrombectomies, or thrombectomies by endovascular devices have all been used. Our case describe an obese patient affected by floating thrombus coming from GSV and diving in common femoral vein successful treated by combined both temporary vena cava insertion and open surgical thrombectomy.

Intermediate-High Risk Pulmonary Embolism.

Project description:Limited information exists about the prevalence, management, and outcomes of intermediate-high risk patients with acute pulmonary embolism (PE). In a prospective cohort study, we evaluated consecutive patients with intermediate-high risk PE at a large, tertiary, academic medical center between January 1, 2015 and March 31, 2019. Adjudicated outcomes included PE-related mortality and a complicated course through 30 days after initiation of PE treatment. Repeat systolic blood pressure (SBP), heart rate (HR), brain natriuretic peptide (BNP), and cardiac troponin I (cTnI) measurements, and echocardiography were performed within 48 hours after diagnosis. Among 1,015 normotensive patients with acute PE, 97 (9.6%) had intermediate-high risk PE. A 30-day complicated course and 30-day PE-related mortality occurred in 23 (24%) and 7 patients (7.2%) with intermediate-high risk PE. Seventeen (18%) intermediate-high risk patients received reperfusion therapy. Within 48 hours after initiation of anticoagulation, normalization of SBP, HR, cTnI, BNP, and echocardiography occurred in 82, 86, 78, 72, and 33% of survivors with intermediate-high risk PE who did not receive immediate thrombolysis. A complicated course between day 2 and day 30 after PE diagnosis for the patients who normalized SBP, HR, cTnI, BNP, and echocardiography measured at 48 hours occurred in 2.9, 1.4, 4.5, 3.3, and 14.3%, respectively. Intermediate-high risk PE occurs in approximately one-tenth of patients with acute symptomatic PE, and is associated with high morbidity and mortality. Normalization of HR 48 hours after diagnosis might identify a group of patients with a very low risk of deterioration during the first month of follow-up.

Drotrecogin alpha: a rational approach to the treatment of submassive pulmonary embolism?

Project description:Combining therapeutic doses of low-molecular-weight heparins and increasing doses of recombinant activated protein C - Drotrecogin alpha (activated), or DAA - is of theoretical interest with regard to the control of coagulation activation. The study by Dempfle and colleagues presents new data showing that endogenous activated protein C levels do not increase in nonseptic patients with pulmonary embolism. However, the results of the addition of these two treatments are puzzling, leaving unresolved the questionable clinical relevance of this combination and the possible increase in bleeding risk.

Septic coronary artery embolism treated with aspiration thrombectomy: case report and review of literature.

Project description:Coronary embolization is a potentially fatal sequela of endocarditis. We report a case of Candida endocarditis with septic embolism to the left anterior descending coronary artery. This embolism was successfully treated with aspiration thrombectomy followed by balloon angioplasty. The treatment of acute coronary syndrome in the presence of septic embolism is controversial. Aspiration thrombectomy has been performed in this situation before, and it appears to be safer and more feasible than is thrombolysis or percutaneous transluminal angioplasty.

Tissue plasminogen activator dose and pulmonary artery pressure reduction in catheter directed thrombolysis of submassive pulmonary embolism.

Project description:PURPOSE:The purpose of this study is to assess the incremental effect of tissue plasminogen activator (t-PA) dose on pulmonary artery pressure (PAP) and bleeding during catheter directed thrombolysis (CDT) of submassive pulmonary embolism (PE). MATERIALS AND METHODS:Records of 46 consecutive patients (25 men, 21 women, mean age 55±14 y) who underwent CDT for submassive PE between September 2009 and February 2017 were retrospectively reviewed. Mean t-PA rate was 0.7±0.3 mg/h. PAP was measured at baseline and daily until CDT termination. Mixed-effects regression modeling was performed of repeated PAP measures in individual patients. Bleeding events were classified by Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO) and t-PA dose at onset. RESULTS:Mean t-PA dose was 43.0±30.0 mg over 61.9± 28.8 h. Mean systolic PAP decreased from 51.7±15.5 mmHg at baseline to 35.6±12.7 mmHg at CDT termination (p<0.001). Mixed-effects regression revealed a linear decrease in systolic PAP over time (β = -0.37 (SE = 0.05), p<0.001) with reduction in mean systolic PAP to 44.8±1.9 mmHg at 12 mg t-PA/20 h, 39.5±2.0 mmHg at 24 mg t-PA/40 h, and 34.9±2.1 mmHg at 36 mg/60 h. No severe, one moderate, and 8 mild bleeding events occurred; bleeding onset was more frequent at ≤24 mg t-PA (p <0.001). One patient expired from cardiopulmonary arrest after 16 h of CDT (15.4 mg t-PA); no additional intra-procedural fatalities occurred. CONCLUSION:Increased total t-PA dose and CDT duration were associated with greater PAP reduction without increased bleeding events.

Successful Surgical Embolectomy for a Rapidly Deteriorating Patient with Pulmonary Embolism and Hemorrhagic Stroke.

Project description:Pulmonary embolism (PE) is a life-threatening condition. High-risk PE is defined as pulmonary embolism with either hemodynamic collapse, persistent hypotension, and/or organ hypoperfusion. The overall mortality rate associated with high-risk PE remains at approximately 30%. Intermediate-high risk PE is a new term introduced to identify hemodynamically stable PE patients with evidence of right ventricular dysfunction. Thrombolytics therapy is the first choice for treatment of high-risk PE with hemodynamic instability; however, in a patient who failed thrombolytics or have contraindication to thrombolytics, thrombus removal either with open surgical or catheter embolectomy is a good alternative. We report a case of a patient who presented with hemorrhagic stroke complicated by intermediate-high-risk PE that rapidly deteriorated before undergoing successful surgical embolectomy.
