Zatorowością płucną (ZP) nazywamy chorobę, podczas której dochodzi do zamknięcia bądź zwężenia tętnicy płucnej lub jej gałęzi przez materiał zakrzepowy. Celem pracy była analiza zatorowości płucnej w okresie przed (grupa A) i w czasie pandemii Covid-19 (grupa B). Porównawcza analiza obejmowała częstość występowania, płeć, wiek oraz lokalizację materiału zatorowego. Analizie statystycznej poddano 660 pacjentów. W okresie przed pandemią odsetek badań pacjentów z podejrzeniem zatorowości płucnej w stosunku do wszystkich badań TK wynosił 2,3%, a w czasie pandemii 4,9%. Potwierdzono obecność materiału zatorowego w grupie A w 32% przypadków, natomiast w grupie B w 30% przypadków. W porównaniu z całkowitą liczbą badań TK – przed pandemią zdiagnozowano zatorowość płucną u 0,7% wszystkich badanych pacjentów. Dla okresu w czasie pandemii odsetek ten wynosił 1,4%, przy czym jedynie w 15% byli to pacjenci ze zdiagnozowanym Covid-19. W grupie A odsetek kobiet wynosił 55% i 45% mężczyzn. W grupie B odpowiednio 51% kobiet i 49% mężczyzn; w przypadku pacjentów z COVID-19: 61% kobiet, 31% mężczyzn. Dla obu grup profil częstości występowania materiału zatorowego był taki sam – najczęściej obustronnie, następnie po stronie prawej i najrzadziej po stronie lewej. Odpowiedni odsetek wynosił: dla grupy A 69, 7 i 24%, a dla grupy B 63, 15 i 22%.

Pulmonary embolism (PE) is a disease in which the pulmonary artery or its branches are blocked or narrowed by thrombotic material. The aim of the study was to analyze pulmonary embolism in the period before (group A) and during the Covid-19 pandemic (group B). Comparative analysis included incidence, gender, age and location of embolic material. 660 patients were subjected to statistical analysis. In the period before the pandemic, the percentage of examinations of patients with suspected pulmonary embolism in relation to all CT examinations was 2.3%, and during the pandemic it was 4.9%. The presence of embolic material was confirmed in group A in 32% of cases, and in group B in 30% of cases. Compared to the total number of CT scans, 0.7% of all patients tested had been diagnosed with pulmonary embolism before the pandemic. For the period during the pandemic, this percentage was 1.4%, with only 15% of patients diagnosed with COVID-19. In group A, the percentage of women was 55% and 45% of men. In group B, 51% of women and 49% of men, respectively; in the case of patients with Covid-19, 61% women, 31% men. For both groups, the profile of the incidence of embolic material was the same – most often bilaterally, then on the right side and least often on the left side. The corresponding percentages were: for group A 69, 7 and 24% and for group B 63, 15 and 22%.

Acute pulmonary embolism (APE) is one of the main causes of cardiovascular deaths and anticoagulant treatment plays a key role in preventing recurrent episodes, chronic thromboembolic pulmonary hypertension (CTEPH), and deaths. The aim of this study is to assess the real-life trends and to determine factors associated with the choice of anticoagulation therapy in patients with APE. This is a single center prospective open study. We followed 178 consecutive patients admitted to the tertiary clinical center with APE proven with computed tomography (CT) scan within period of 24 months. A total number of 178 patients with APE were enrolled in the study. 48.9% of subjects were hospitalized in cardiology department. As a prolonged anticoagulant therapy 35.7% of study cohort received direct oral anticoagulants (DOACs), 35.1% LMWH, and 29.2% vitamin K antagonists (VKA), respectively. No statistically significant differences were found between the departments regarding frequency of prescribing anticoagulants (p=0.15). The multivariable analysis showed that oral anti-coagulants (OACs) were less likely to be prescribed than LMWH in patients with malignancy, history of major bleeding, serious medical condition and altered mental status. OACs were preferred over LMWH in symptoms of deep vein thrombosis (DVT). VKA were significantly less likely to be chosen than DOACs in patients with history of orthopaedics procedure. After six months anticoagulation therapy was discontinued in 24.3% of patients. Concluding, the form of anticoagulant therapy was associated with the presence of chronic diseases. LMWH was prescribed in high bleeding risk patients more frequently.

Pulmonary embolism (PE) is caused by occlusion of the pulmonary artery or its branches. CTA is a "gold standard" for the diagnosis and extent determination of PE. The etiology of embolic material may influence the extent and localization of embolism. The CTA assessment of influence of PE etiology on extent of vascular occlusion and clot localization. The study group consisted of 24 patients divided into two subgroups (15 patients with deep venous thrombosis - DVT and 9 patients with heart failure/chronic obstructive pulmonary disease - HF/COPD; respectively group A and group B) were taken into consideration. The location of clots and an average percentage of vascular stenosis in CTA were analysed in these two subgroups. The mean percentage of vessel occlusion was 20,49% vs. 14,22% respectively in group A vs. group B. Bilateral occlusion of vessels was more frequent in group A and unilateral in group B. DVT may predispose to bilateral occlusion and more severe vessels obstruction.
