Abstract Background Pulmonary embolism (PE) is the third most common acute cardiovascular syndrome. Percutaneous catheter directed hydro-mechanical defragmentation (HMD) is one of the recommended treatment options for PE in patients with contraindications to thrombolytic therapy or failed systemic thrombolysis (ST). We aimed to identify the safety and outcomes of catheter directed HMD in patients with high-risk PE. This nonrandomized controlled trial enrolled all patients with confirmed diagnoses of high- and intermediate-high-risk PE from October 2019 till January 2021. Fifty patients were included and divided into two groups by the PE response team according to the presence or absence of a contraindication for ST. Group B (ST) consists of 25 patients and group A (HMD) of 25 patients who cannot receive ST. Results The two groups were comparable regarding baseline clinical characteristics with mean age 51 ± 13 years. In group A, systolic blood pressure (BP) and oxygen saturation increased after 24 h (p = 0.002) and 48 h (p < 0.001) compared to pre-HMD procedure. Mean pulmonary artery systolic pressure (PASP) and respiratory rate (RR) decreased after 48 h and at 30 days (p < 0.001) compared to pre-HMD procedure. The increase in systolic BP and oxygen saturation were significantly higher in HMD group compared with ST group after 48 h and at 30 days (p < 0.007). The decrease in PASP and RR was significantly higher in HMD group compared to ST group after 48 h and at 30 days (p < 0.001). Mortality rate at 30 days was 20% in HMD group compared to 32% in ST group. Conclusions Catheter directed HMD for high-risk and intermediate-high-risk PE is safe and effective with acceptable mortality Trial registration Clinical trial ID: NCT04099186.

Abstract Funding Acknowledgements Type of funding sources: None. Background Pulmonary embolism (PE) is the third global cause of cardiovascular death. Treatment of high-risk cases and selected intermediate-risk cases is based on systemic thrombolysis, which can be inconvenient in patients with a contraindications for thrombolysis. Catheter-directed therapies are emerging as an alternative for treatment when there is an increased bleeding risk. Methods One-center retrospective study of patients with high or intermediate-high risk PE with contraindications for systemic thrombolysis. Catheter directed rheolytic thrombectomy or mechanical thrombectomy was performed, assessing its effect on clinical variables, pulmonary artery systolic pressure (PASP), PaO2/FiO2, and the occurrence of complications. Results In 12 patients with PE treated with catheter-directed therapy, we observed a mean increase of the PaO2/FiO2 of 62 mm Hg (p = 0.013), as well mean reduction in the PASP of 13 mm Hg (p &lt; 0.001), as can be observed in the figure. As complications, there was one case of hemoptysis, and two of hemolysis, with an in-hospital mortality of 16.7%. Conclusion Catheter-directed therapy in patients with high or intermediate-high risk PE is a feasible option when there are contraindications for thrombolysis or there is a high bleeding risk. It has been shown to improve surrogate endpoints as PASP and right to left ventricle ratio in other studies, although data on mortality from a randomized trial is lacking. Abstract Figure.

Objectives. We 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 Results. Fourteen 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. Conclusions. CDT 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.

The aim of the study was to evaluate the immediate results of treatment of high-risk PE developed against the background of COVID-19, and to analyze the features of the clinical course. Material and methods. The study is based on the experience of treatment applied to three patients with pulmonary embolism (PE) that developed against the background of COVID-19. The group under consideration is represented by males. The average age was 41 ± 3.1 years old. Verification of the primary diagnosis of COVID-19 was based on positive results of polymerase chain reaction, supplemented by the results of computed tomography. The formation of high-risk PE was noted on the 5th–7th day from the moment of hospitalization. There was also a decrease in SO2 below 85%, РаО2 — below 76 mm Hg, Borg index > 8, which required non-invasive high-flow ventilation. Catheterization of the right chambers of the heart with a Swan–Ganz catheter revealed an increase in systolic pressure in the right ventricle to 57 ± 1.2 mm Hg, and diastolic pressure to 13 ± 0.34 mm Hg. Pulmonary hypertension increased up to 70 mm Hg. Changes in the biochemical analysis of blood consisted in increasing the level of troponin I to 0.65 ± 0.14 ng/ml, С reactive protein — to 5.42 ± 2.1 mg/l, and creatine phosphokinase — to 324 ± 23.1 units. An increase in the D-dimer level was observed (0.68 ± 0.11 mg/l). Systemic thrombolysis actilyse was performed in all the cases. Results. Positive clinical dynamics was observed up to 15 hours after thrombolytic therapy. The level of SO2 came back to the initial values and was in the range 93–96% and RaO2 — from 86–92 mm Hg by the end of the first day after the intervention. The average pressure gradient in the pulmonary artery was 32 ± 4.12 mm Hg at the time of discharge, and at the peak — 44 ± 5.3 mm Hg.

Introduction: Risk stratification tools including the Pulmonary Embolism Severity Index (PESI) and BOVA rely on complicated calculations that give less attention to hemodynamic parameters predictive of cardiogenic shock in acute pulmonary embolism (PE). We explored the possibility that simultaneous measurement of right sided and left sided non-invasive hemodynamic parameters by echocardiography may predict adverse sequelae in the context of acute PE. Methods: We retrospectively reviewed all Pulmonary Embolism Response Team (PERT) activations between 2014 and 2020. The PESI and BOVA scores were calculated and their performance in predicting adverse events was compared to pulmonary artery elastance (PAE). PAE (mmHg/mL) was calculated by dividing the Pulmonary Artery Systolic pressure (PASP) by the LV Stroke (SV). Blood biomarkers (troponin T, NT-proBNP, and lactate) were recorded. The composite primary outcome was: 1) need for advanced intervention, 2) cardiac arrest, and 3) in-hospital mortality. Multivariate and univariate regression was used to analyze outcomes. Results: 215 of 343 patients met inclusion criteria. Baseline characteristics were similar in patients with PAE <1 and PAE ≥ 1. PAE ≥ 1 was common in intermediate-high risk PE (85.7% vs 63.1%, p <0.001), with greater [NT-proBNP, pg/mL] (3599 vs 1427.5, p=0.001) and [lactate, mM] (2.9 vs 1.8. p=0.003). PAE ≥ 1 predicted the composite endpoint with odds ratio (OR) of 2.31 (95% CI 1.3-4.2, p=0.005), Comparatively BOVA had adjusted OR of 1.3 (95% CI, 1.1-1.6, p = 0.01) and PESI was not significant with OR of 1.4 (95% CI, 1 -2.1, p = 0.055) in predicting composite outcomes. Conclusion: In the context of acute high risk PE, PAE ≥ 1.0 is a novel and independent predictor of adverse cardiovascular events and mortality that should be prospectively validated.

Abstract Background Despite the fast-growing understanding of the coronavirus disease 2019 (COVID-19), patient management remains largely empirical or based on retrospective studies. In this complex scenario, an important clinical issue appears to be represented by the high prevalence of thromboembolic events, but the data regarding high-risk pulmonary embolism (PE) is still not available. Case summary A patient with COVID-19 developed sudden shortness of breath and hypoxia. Early echocardiographic diagnosis of high-risk PE related to right heart thrombus was performed. Systemic thrombolysis was administered with excellent clinical and haemodynamic response. Discussion Pulmonary thromboembolism is a common occurrence in severe COVID-19 infection. In our experience, systemic thrombolysis proved to be effective and for this reason may be considered for life-threatening PE in COVID-19 patients.

Introduction: Current treatment guidelines advocate for the aggressive management of both high-risk and subsets of moderate-risk pulmonary embolism (PE) with fibrinolytic therapy. However, there is limited evidence on the risks and benefits of fibrinolytic therapy in PE, with mortality improvement still to be proven. This study aimed to report the incidence of major bleeding and death after thrombolysis for PE. Methods: A health records review was performed on data from two hospitals between 2007 and 2017. Pharmacy identified all patients who had received either alteplase or tenecteplase. Trained abstractors reviewed each chart to determine the indication for thrombolytic therapy. Patients were included if they received systemic thrombolysis for diagnosed or presumed PE. Data was extracted on 30-day mortality, International Society of Thrombosis and Hemostasis defined major bleeding within 30 days, premorbid anticoagulant and antiplatelet prescription, age, sex, comorbidities, renal function, history of bleeding, type and dose of thrombolytic and category of PE (high or moderate risk). Results: 1534 patients were identified, of which 72 received systemic thrombolysis for PE. The median age was 57, 34 were male, 17 with a history of venous thrombosis and 12 with cancer. Fifty-four were classified as having high-risk PE, of whom 39 received cardiopulmonary resuscitation (CPR) when thrombolysis was administered. Formal confirmatory imagining for PE was obtained in only 23/39 patients who were in cardiac arrest. Eighteen patients were classified as moderate-risk PE. The incidence of major bleeding was 28/54 (52%, 95% CI 39-65%), and 3/18 (17%, 95% CI 6-39%) for the high and moderate risk groups respectively. There were 4 intracranial bleeds, all in the high-risk PE group. The only significant predictor of major bleeding was the need for CPR at the point of administration of the thrombolytic agent (OR 2.6, 95% CI 1.0-7.5, adjusted for age). Thirty-four patients died within 30 days (47%, 95% CI 36-59%), all in the high-risk PE group. Death was not associated with any demographic variable on univariate analysis. Death occurred in 28/39 (72%, 95%CI 56-83%) patients who received CPR and 6/33 (18%, 95% CI 9-34%) who did not. Conclusion: We found a high incidence of 30-day major bleeding and death following administration of thrombolysis for PE which will help inform future prognostic discussions in our institution.

To evaluate the prognosis after local thrombolysis compared to systemic thrombolysis in high-risk pulmonary embolism. Observational study during 13 years which included 37 patients with high-risk pulmonary embolism treated with local thrombolysis and 36 patients with systemic thrombolysis (streptokinase, 250 000 UI/30 minutes followed by 100 000 UI/h). Cardiogenic shock has totally remitted in the group with local thrombolysis ( P = .002). The decrease in pressure gradient between right ventricle and right atrium was comparable in both groups in the acute period (the results being influenced by the higher in-hospital mortality after systemic thrombolysis), but significantly better in the next 24 months follow-up after in situ thrombolysis. Major and minor bleeding did not have significant differences. In hospital, mortality was significantly lower in the group with local thrombolysis ( P = .003), but for the next 24 months follow-up, the survival was comparable in both groups. Local thrombolysis, during the hospitalization, was associated with lower mortality rate comparing with systemic thrombolysis. In the next 24 months follow-up, the evolution of residual pulmonary hypertension was significantly better after in situ thrombolysis.

OBJECTIVE To find out the effectiveness of neural mobilization and stretching exercise for the management of sciatica BACKGROUND Sciatica is described as pain, radiating to the leg below the knee joint and caused by irritation of the sciatic nerve or nerve trunk. There are many treatment options for the management of sciatica, including stretching exercise and neural mobilization. MATERIAL AND METHODS This study was a Randomized Controlled Trial. 94 patients from physical therapy OPD of tertiary care hospitals, were participated in this study. Hence, 47 patients were randomly allocated into each group A and B. Before and after the nine treatment sessions, both groups were assessed with VAS, SLR ROM and Quebec back pain disability scale. In group A, neural mobilization with conventional therapy (heat and TENS) was applied, while stretching exercise with same conventional therapy was applied to group B. RESULTS It was observed that both treatments were helpful in reducing the symptoms. The analysis showed significant improvement (p-value <0.05) in the SLR to 60.851o±6.86oand Quebec score to 23.617±3.125, after the stretching exercise. Hence, both treatments were equally effective in reducing pain (p-value >0.05). CONCLUSION Stretching exercise is more effective in the improvement of SLR and disability. Furthermore, both techniques are helpful in the management of pain. KEY WORDS Sciatica, Stretching, Neural Mobilization, Straight Leg Raising, Visual Analogue Scale, TENS.

Systemic Thrombolysis

Massive pulmonary embolism has a high mortality rate. Standard treatment includes systemic thrombolysis. If this fails, surgical embolectomy or a percutaneous catheter-guided approach is advised in current guidelines. However, these treatment options might not be available in many non-tertiary care hospitals. We describe a case of a 25-year old woman with cardiac arrest from massive pulmonary embolism. She was treated with thrombus fragmentation using a pulmonary artery catheter and intra-pulmonary thrombolysis after failure of systemic thrombolysis along with 90 minutes of cardiopulmonary resuscitation (CPR). Neurological recovery was excellent and pulmonary pressure was normalized after one month. Besides catheter guided thrombus fragmentation and thrombolysis, we contribute the successful outcome to a combination of ultrasound-guided therapy, capnography-guided CPR, and “crew resource management” principles. Our case illustrates that a pulmonary artery catheter can be used successfully in a non-tertiary setting, to perform a percutaneous procedure during CPR and that full neurological recovery is possible after 90 minutes of CPR.
