Vascular Obstruction

Aim. To study effect of the level of vascular obstruction on the clinical manifestations of pulmonary embolism (PE). Material and methods. 63 patients with PE were included in this study. PE was verified by multidetector computed tomography (MSCT) with pulmonary angiography. 43 patients with high-risk PE survived the first week of the disease. In the remaining 20 patients with community-acquired pneumonia PE was diagnosed using MSCT pulmonary angiography in the first week of illness. Results. Obstruction of the trunk of the pulmonary artery or its lobar branches was detected in 34 (79.1%) patients with a high risk of PE and in only 2 (10%) ones with low-risk PE (p <0,001). The development of pneumonia complicated the course of the disease in 14 (32.6%) patients with a high risk of pulmonary embolism. The clots in the segmental branches of the pulmonary artery were identified in 9 (64.3%) patients with pneumonia. In high-risk patients with PE without pneumonia the lesion of segmental branches was detected only in 1 (3.4%) case (p <0,001). In patients with pneumonia at low risk of PE, the obstruction segmental branches was detected in 17 (85%) cases. Conclusion. The development of obstructive shock in PE is associated with a trunk embolism and/or the main pulmonary artery branches embolism. Infarction pneumonia is associated with the lesions of segmental branches of the pulmonary artery.

Aim. To detect the effect of the feature of the pulmonary vascular obstruction on the clinical manifestations of pulmonary embolism (PE). Materials and methods. The 127 patients with PE were included in this study. PE verified with multidetector computed tomography with pulmonary angiography. Among them were 57 patients with high-risk PE, and 39 patients with intermediate-risk PE and 31 patients with low-risk PE. The pulmonary artery obstruction index and the obstruction level were determined. Results. The mean values of the pulmonary artery obstruction index in high and intermediate risk patients were 42.5%, and in low risk patients 12.5% (p0.001). The trunk or main branches obstruction was in 80.7% of high-risk PE patients, the main or lobar branches obstruction in 92.3% of intermediate-risk patients and lobar or segmental branches obstruction in 93.5% of low-risk patients. Pulmonary infarction was detected in 89.2% of patients with the segmental branches obstruction and with another level of obstruction in 28.0% of patients only (p0.001). Conclusion. The hemodynamic disorder in pulmonary embolism associate with the pulmonary artery obstruction index of more than 30%. The development of obstructive shock is associated with the pulmonary artery trunk obstruction, and the development of pulmonary infarction associated with the segmental branches obstruction.

The Relationship

Summary Background The aim of this study was to determine levels of Mid-regional Pro-adrenomedullin (MR-proADM) and Mid-regional Pro-atrial Natriuretic Peptide (MR-proANP) in patients with acute pulmonary embolism (PE), the relationship between these parameters and the risk classification in addition to determining the relationship between 1- and 3-month mortality. Methods 82 PE patients and 50 healthy control subjects were included in the study. Blood samples for MR-proANP and MR-proADM were obtained from the subjects prior to the treatment. Risk stratification was determined according to sPESI (Simplified Pulmonary Embolism Severity Index). Following these initial measurements, cases with PE were assessed in terms of all causative and PE related mortalities. Results The mean serum MR-proANP and MR-proADM levels in acute PE patients were found to be statistically higher compared to the control group (p < 0.001, p < 0.01; respectively) and statistically significantly higher in high-risk patients than low-risk patients (p < 0.01, p < 0.05; respectively). No statistical difference was determined in high-risk patients in case of sPESI compared to low-risk patients while hospital mortality rates were higher. It was determined that the hospital mortality rate in cases with MR-proANP ≥ 123.30 pmol/L and the total 3-month mortality rate in cases with MR-proADM ≥ 152.2 pg/mL showed a statistically significant increase. Conclusions This study showed that MR-proANP and MR-proADM may be an important biochemical marker for determining high-risk cases and predicting the mortality in PE patients and we believe that these results should be supported by further and extensive studies.

We compared the prognostic performance of the 2014 European Society of Cardiology (ESC) risk stratification algorithm with the previous 2008 ESC algorithm, the Bova score and the modified FAST score (based on a positive heart-type fatty acid-binding protein (H-FABP) test, syncope and tachycardia, modified using high-sensitivity troponin T instead of H-FABP) in 388 normotensive pulmonary embolism patients included in a single-centre cohort study.Overall, 25 patients (6.4%) had an adverse 30-day outcome. Regardless of the score or algorithm used, the rate of an adverse outcome was highest in the intermediate-high-risk classes, while all patients classified as low-risk had a favourable outcome (no pulmonary embolism-related deaths, 0–1.4% adverse outcome). The area under the curve for predicting an adverse outcome was higher for the 2014 ESC algorithm (0.76, 95% CI 0.68–0.84) compared with the 2008 ESC algorithm (0.65, 95% CI 0.56–0.73) and highest for the modified FAST score (0.82, 95% CI 0.75–0.89). Patients classified as intermediate-high-risk by the 2014 ESC algorithm had a 8.9-fold increased risk for an adverse outcome (3.2–24.2, p<0.001 compared with intermediate-low- and low-risk patients), while the highest OR was observed for a modified FAST score ≥3 points (OR 15.9, 95% CI 5.3–47.6, p<0.001).The 2014 ESC algorithm improves risk stratification of not-high-risk pulmonary embolism compared with the 2008 ESC algorithm. All scores and algorithms accurately identified low-risk patients, while the modified FAST score appears more suitable to identify intermediate-high-risk patients.

Aim of study. Comprehensive assessment of clinical and hemodynamic results of surgical treatment of high- and intermediate-high risk of pulmonary embolism in a group of patients who underwent spinal surgery.Materials and methods. The analysis of the results of open surgical treatment of pulmonary embolism in high- and intermediate-high-risk patients after neurosurgical operations on the spine in the period from 2013 through 2019. The study group included 5 patients. The average age of patients was 59.74±3.42 years. The Wells index was 9.2±2.4. The Pesi index of the studied patients was in the range of 100–126, which allowed them to be classified as a high-risk group of 30-day mortality (class IV). Clinical manifestations of pulmonary embolism developed on average by 5.8±1.08 days after the initial neurosurgical intervention. The calculated pressure in the pulmonary artery was 56.6±8.22 mm Hg. In all cases, surgical intervention was performed for emergency indications, in conditions of artificial blood circulation, without aortic compression during the main stage of the operation.Results. The 30-day survival rate of patients was 100%. Among non-lethal postoperative complications, acute cardiovascular failure and hepatic-renal failure prevailed, which were levelled by the time the patients were transferred to a cardiac hospital. In 1 patient, the early postoperative period was complicated by the development of exudative pericarditis with cardiac tamponade, which required a finger revision of the anterior mediastinum, its drainage for 2 days. In all cases, there was an improvement in the condition of patients, in the form of increased tolerance to physical activity. The estimated pressure in the pulmonary artery at the time of discharge was 24.69±8.03 mm Hg.Conclusions. Surgical treatment of acute pulmonary embolism of high- and intermediate-high risk of early death in a group of patients with a neurosurgical profile is a highly effective and reliable method with great prospects for application.

Abstract Abstract 3416 Introduction: Therapy of pulmonary embolism (PE) today is based on risk stratification scores. Outpatient treatment for selected low-risk patients seems feasible, but data are derived from selected patient cohorts. Little is known about risk factors or clinical outcomes in unselected cohorts. In our hospital, outpatient treatment of low-risk-PE has been standard for nearly ten years. We retrospectively analyzed risk profile and 6-month-outcome of in-hospital or outpatient treatment in patients with community-aquired acute PE (CA-PE). Objectives: To evaluate the proportion of patients with outpatient or early discharge treatment of CA-PE, to evaluate the value of HESTIA score to discriminate between low and high risk patients and to assess 6-month outcome. Methods: Retrospective evaluation of all cases with CA-PE. Inclusion criteria: 1) PE symptoms as reason for hospitalization (exclusion of hospital-aquired PE); 2) symptomatic and confirmed PE (CT or V/Q scan). Evaluation of patient characteristics, hemodynamic and echocardiographic parameters and lab values and group comparisons between outpatient treatment (OT; hospitalized < 24h), early discharge (ED; hospitalized < 72h) and in-hospital treatment (HT) were performed. Result: Between 2000 and 2010, 439 patients were diagnosed with acute CA-PE (table 1). About 25% of patients could be treated as outpatients (n=49; 11.2%) or early discharged (n=63; 14.4%). Patients with in-hospital treatment of PE were significantly older and had more severe PE. Interestingly, the rate of patients with a positive history of VTE was highest in the group of outpatients (45%), followed by the early-discharge group (32%), indicating that these patients are diagnosed at an earlier stage with less severe PE. In contrast, only 25% of patients requiring in-hospital treatment of PE had a positive VTE history. Despite the differences in baseline characteristics, outcomes with regard to recurrent VTE, pulmonary hypertension or mortality were not significantly different between outpatients and early discharge patients. In contrast, outcomes of patients with in-hospital treatment was significantly different with higher mortality (0.0% vs. 3.2% vs. 15.8%). Conclusion: Even before ESC and Hestia scores were implemented, physicians subjective assessment based on hemodynamic, echocardiographic and laboratory parameters clearly discriminated between low, intermediate and high risk PE patients and allowed for outpatient treatment in low-risk PE in 11% of all PE patients. Early discharge was possible in 14% of all patients, despite higher HESTIA scores and a higher rate of elevated troponin levels, initial oxygen requirement or right heart strain in echocardiography. In contrast, patients requiring in-hospital PE treatment were older, had more severe PE and a high 6-month mortality. Despite a positive Hestia score in many patients, about 25% of all community-aquired PE patients can be safely treated as outpatient or early discharge treatment with low 6-month mortality. Disclosures: No relevant conflicts of interest to declare.

Rule Out

Introduction: As the availability of Computed Tomography Pulmonary Angiography (CTPA) to rule out pulmonary embolism (PE) increases, so too does its utilization, and consequent overutilization. A variety of evidence-based algorithms and decision rules using clinical criteria and D-Dimer testing have been proposed as instruments to allow physicians to safely rule out a PE in low-risk patients. However, studies have shown mixed results with respect to both physician uptake of these decision rules and their impact on improving ordering practices among physicians. The objective of this study is to describe the prevalence of D-Dimer utilization among ED physicians and its impact on positive yield rates of CTPAs in a community setting. Methods: Data was collected on all CTPA studies ordered by ED physicians at two very high-volume community hospitals and an affiliated urgent care centre during the 2-year period between January 1, 2016 and December 31, 2017. For each CTPA, we determined if 1) a D-Dimer had been ordered prior to CTPA, if 2) the D-Dimer was positive, and if 3) the CTPA was positive for a PE. Using a chi-square test, we compared the diagnostic yield for those patients who had a D-Dimer prior to their CTPA and those who did not. Results: A total of 2,811 CTPAs were included in the analysis. Of these, 964 CTPAs (34.3%) were ordered without a D-Dimer. Of those 1,847 patients who underwent D-Dimer testing prior to the CTPA, 343 (18.7%) underwent a CTPA despite a negative D-Dimer. When compared as a group, those CTPAs preceded by a D-Dimer showed no significant difference in positive yields when compared to those CTPAs ordered without a prior D-Dimer (9.9% versus 11.3%, p = 0.26). Conclusion: The findings of this study present a complicated picture of the impact of D-Dimer utilization on CTPA ordering patterns. There is evidence of suboptimal uptake of routine D-Dimer ordering, and adherence to guidelines in terms of forgoing CTPAs in low-risk patients with negative D-Dimers. While this study design leaves unanswered the question of how many CTPAs were avoided as a result of a negative D-Dimer, the finding of a similar positive yield among those patients who had a D-Dimer ordered versus those who did not is interesting, and illustrative of the issues arising from the high false-positive rates associated with D-Dimer screening.

Abstract Background. New management strategies, risk stratification procedures and treatments have become available over the last years for patients with acute pulmonary embolism (PE), leading to changes in clinical practice and potentially influencing patient's course and outcome. Methods: The COntemporary management of Pulmonary Embolism (COPE) is an academical prospective, non-interventional, multicentre study in patients with confirmed acute symptomatic PE. In-hospital and 30-day mortality were the co-primary study outcomes. At first evaluation, patients were categorized at low-risk (simplified PESI [sPESI]=0), intermediate-risk (further classified based presence/absence of increased levels and right ventricle dysfunction [RVD] at echocardiography) and high-risk (shock or cardiac arrest). Results. Among 5213 study patients, PE was confirmed by computed tomography in 96.3% and at least one test for risk stratification was obtained in more than 80% (81% echocardiography, 83% troponin, 56% brain natriuretic peptide/NT-pro BNP). Among 4885 patients entering the Emergency Department for acute PE, 1.2% were managed as outpatients and 5.8% by short-observation. In-hospital, 289 patients underwent reperfusion (5.5%); at discharge, 6.7% received a vitamin K antagonist and 75.6% a direct oral anticoagulant. Median duration of hospitalization was 7 days (IQR 5-12 days). Overall in-hospital mortality was 3.4% (49% due to PE, 16% cancer and 4.5% major bleeding) and 30-day mortality 4.8% (36% PE, 28% cancer and 4% major bleeding). In-hospital major bleeding was 2.6%. Death at 30 days occurred in 22.6% of 177 high-risk patients, in 6% of the 3281 intermediate-risk and in 0.5% of 1702 low-risk patients. Time to death at 30 days in patients at low, intermediate and high risk for death is reported in the Figure. Conclusions: COPE is the largest ever cohort of patients with acute PE. In this contemporary scenario, the majority of patients received CT for diagnosis, at least one test for risk stratification and direct oral anticoagulants as long-term treatment. Short term death remains not negligible in patients with high and intermediate-risk PE. Figure 1 Figure 1.

Abstract Background To evaluate the value of CT pulmonary angiography (CTPA) in evaluating the therapeutic efficacy of pulmonary embolism (PE) through the study of CT pulmonary artery obstruction index (PAOI),right ventricular function parameters and some clinical indexes related to coagulation function and cardiac function injury.Materials and methods Select 30 patients with pulmonary embolism who underwent CTPA examination before and after treatment in our hospital, sort out their CTPA images before and after treatment, and obtain PAOI and right heart function parameters, including ascending aorta diameter (AAd), main pulmonary artery diameter (MPAd), ratio of main pulmonary artery diameter to ascending aorta diameter (MPAd/AAd), right pulmonary artery trunk diameter (RPAd), left pulmonary artery trunk diameter (LPAd), the ratio of the maximum short axis diameter of the right ventricle to the maximum short axis diameter of the left ventricle (RVd/LVd), and calculate the pulmonary artery obstruction index (PAOI).At the same time obtain the required clinical indicators, including serum D-dimer, N-terminal B-type natriuretic peptide precursor (NT-proBNP), cardiac troponin I (cTnI), myocardial enzyme profile (aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK)).Results MPAd, RPAd, LPAd, RVd / LVd, PAOI, D-dimer, cTnI, CK, LDH, AST had significant changes after treatment (P < 0.05), while the other parameters and indexes had no significant differences before and after treatment (P > 0.05). PAOI is positively correlated with RVd/LVd, MPAd, D-dimer. The correlation coefficient ranges from 0.281 to 0.423, among which, the correlation with D-dimer is the closest, with a correlation coefficient of 0.423. There was no significant correlation between other parameters and PAOI (P < 0.05).Conclusion CTPA is of great significance in evaluating the severity of pulmonary embolism, right heart function and therapeutic efficacy.

Background. The Pulmonary Embolism Severity Index (PESI) score can risk-stratify patients with PE but its widespread use is uncertain. With the PESI, we compared length of hospital stay between low, moderate, and high risk PE patients and determined the number of low risk PE patients who were discharged early. Methods. PE patients admitted to St. Joseph Mercy Oakland Hospital from January 2005 to August 2010 were screened. PESI score stratified acute PE patients into low (<85), moderate (86–105), and high (>105) risk categories and their length of hospital stay was compared. Patients with low risk PE discharged early (≤3 days) were calculated. Results. Among 315 PE patients, 51.7% were at low risk. No significant difference in hospital stay between low (7.11 ± 3 d) and moderate (6.88 ± 2.9 d) risk, p > 0.05, as well as low and high risk (7.28 ± 3.0 d), p > 0.05, was found. 9% of low risk patients were discharged ≤ 3 days. Conclusions. There was no significant difference in length of hospital stay between low and high risk groups and only a small number of low risk patients were discharged from the hospital early suggesting that risk tools like PESI may not have a widespread use.
