Follow-up
pulmonary angiography after 24 hours of lysis may help to determine residual clot burden, the need for catheter repositioning, and identify patients requiring continued therapy and/or additional interventions.
Do not order computed tomography
pulmonary angiography when evaluating patients for suspected pulmonary embolism unless: (1) the patient has a D-dimer concentration [greater than or equal to] 1000 ng/mL; or (2) the patient has a D-dimer concentration [greater than or equal to] 500 ng/mL, PLUS: (A) clinical signs of deep vein thrombosis, (B) hemoptysis, or (C) you think pulmonary embolism is the most likely diagnosis.
In a previous clinical trial, known as the YEARS study, a specialized diagnostic algorithm had a low incidence of failure in men and women with clinically suspected PE, as shown by a venous thromboembolism (VTE) rate of just 0.61% at 3 months and by use of CT
pulmonary angiography that was 14 percentage points lower than with a conventional algorithmic approach.
Contrast-enhanced computed tomography
pulmonary angiography (CTPA) is the standard imaging modality for the diagnosis of PE.
d-dimers) and/or imaging modalities such as computed tomographic
pulmonary angiography (CTPA) or a ventilation perfusion scan.
The 25 chapters address integrated imaging modalities in the cardiac catheterization laboratory; basic elements of cardiac catheterization and interventional cardiology, including complications, vascular access, pressure measurements, pitfalls in the evaluation of hemodynamic data, pericardial disease, pediatric cardiac catheterization, coronary anomalies, evaluation of myocardial blood flow, intravascular ultrasounds, and coronary, peripheral, and
pulmonary angiography; and key areas of interventional cardiology, from percutaneous transluminal coronary angioplasty to advanced epicardial access.
A subsequent computed tomography
pulmonary angiography (CTPA) to rule out a pulmonary embolism revealed no hypodense filling defects of the pulmonary arteries.

22, 2018 (HealthDay News) -- A diagnostic strategy based on pretest clinical probability assessment, high-sensitivity D-dimer testing, bilateral lower-limb compression ultrasonography (CUS), and computed tomography
pulmonary angiography (CTPA) can safely rule out pulmonary embolism (PE) in pregnant women, according to a study published online Oct.
Objective: To evaluate the role of multiplanar reformations (MPR) in the diagnosis of peripheral pulmonary embolism on multidetector computed tomography (MDCT)
pulmonary angiography.
It is usually diagnosed in the presence of a triad of liver disease, oxygenation defect, and intrapulmonary microvascular dilatations [7] on
pulmonary angiography. However, contrastenhanced transthoracic echocardiography with saline (bubble test, as done in our patient) is an equally reliable investigation to ascertain the presence of pulmonary vascular dilatation.
