The association between the proximal extension of the clot and the severity of pulmonary embolism (PE): a proposal for a new radiological score for PE

Abstract

Background. The aim of the study was to investigate the association between the proximal level of the clot and the severity of pulmonary embolism (PE).

Elevated gamma glutamyl transferase levels are associated with the location of acute pulmonary embolism. Cross-sectional evaluation in hospital setting

“…to hemodynamic instability). Although there have been studies indicating a direct correlation between the obstruction level of the pulmonary artery, coagulation load and mortality, 5 Mansencal et al did not find any discriminant correlation between pulmonary hemodynamic data and prognosis. 19 Similarly, Araos et al…”

“…21 In risk classification, detection of proximal extension in pulmonary embolism patients is a prognostic factor with unrecognized value. 5 The cardiac biomarkers troponin and natriuretic peptide have emerged as promising tools for evaluating the risk among patients diagnosed with APE. Increased cardiac troponin levels in APE can be explained by the increased right ventricular wall pressure, which leads to compression of the right coronary artery and direct myocardial damage.…”

“…The location of the embolism is associated with clinical findings and disease severity. 5 Cardiac biomarkers, including troponin and natriuretic peptide, are used as mortality predictors for APE. [1][2][3][4][5][6] Although some studies have indicated a correlation between the location of the embolism and blood D-dimer and creatinine levels, others indicate the opposite, i.e.…”

Risk Stratification of Patients with Acute Pulmonary Embolism

“…The greatest role appears to be the identification of low-risk patients due to its high negative predictive value ( Other CT-derived parameters have also been investigated. The presence of interventricular septal bowing is predictive of PE-related deaths but has low sensitivity and high interobserver variability (Araoz et al, 2007), scores to quantify the extent and location of pulmonary artery obstruction have been developed but not shown to be of prognostic relevance yet (Qanadil et al, 2001;Ghanima et al, 2007).…”

Anatomic Localization of Thrombi in Our Cases of Pulmonary Thromboembolism

“…Günümüzde klinik skorlama, alt ekstremite venöz doppler ultrasonografisi, D-dimer, ekokardiyografik inceleme ve pulmoner BT anjiografinin yer aldığı algoritmalar invazif pulmoner anjiografi gereksinimini büyük ölçüde azaltmıştır. Arter lümenindeki trombüsün neden olduğu dolma defektini saptayan multidedektör spiral bilgisayarlı tomografi pulmoner anjiyografi (BTPA) görüntüleme yöntemi tanıda halen yaygın olarak kullanılmaktadır ve PTE tanısında birinci sırada başvurulan görüntüleme yöntemidir [9]. Multidedektör spiral BTPA, PTE için hem tanısal bir yaklaşım sunmakta hem de hastalığın ağır-lığı ve yaygınlığına ilişkin bilgi vermektedir.…”
