Abstract
Background
Critically ill patients in intensive-care units are at high risk for pulmonary embolism (PE). As a result of modern multi-detector computed tomographic angiography (MDCT) increased visualization of peripheral pulmonary arteries, isolated subsegmental pulmonary embolisms (ISSPE) are increasingly being detected.
Aim
The aim of this study was to investigate the rate, impact on treatment, and outcome of unsuspected ISSPE in critically ill patients receiving MDCT. The secondary aim was to investigate the potential impact of contrast media-induced nephropathy (CIN) in our cohort.
Methods
We conducted a retrospective single-centre analysis on critically ill adult patients treated between January 2009 and December 2012 who underwent a contrast-enhanced chest MDCT. We excluded patients with clinical suspicion of PE/ISSPE prior to CT and patients with MDCT confirmed central PE. Clinical findings, laboratory parameters, and outcome data were recorded.
Results
We identified 240 ICU patients not suspected for PE receiving MDCT. A total of 12 Patients (5 %) showed unexpected ISSPE representing increased 24 h mortality (16.7 vs. 3.5 %; p = 0.026) compared to non-ISPPE/non-PE patients. A 30-days mortality did not differ between the groups (33.3 vs. 33.8 %; p = 0.53). Highest mean creatinine serum level in our cohort (n = 240) was found before MDCT with a significant decrease to day 5 (1.4 ± 1.1 vs. 1.1 ± 0.9 mg/dl: p < 0.0001) after contrast media administration.
Conclusion
Critically ill patients are at relevant risk for ISSPE. ISSPE was associated with a poor 24 h outcome. In addition, in our cohort, contrast media application was not associated with increased serum creatinine.
