“…Time dependence of CT accuracy is related to the fact that normal postoperative appearances of the mediastinum during the first 2-3 weeks are quite similar to mediastinitis (Fig. 4), and may not return to normal for as long as 2 months after surgery [5][6][7][8]. Increased attenuation of mediastinal fat was recorded in all of our patients, but does not seem to be a specific finding in the postoperative group of patients during the first 3 weeks [6,9,10].…”

Diagnosis was confirmed by surgery are found in up to half of the reported mediastinitis series [1,[5][6][7]. However, gas bubbles and mediastinal fluid collections may be normal findings for at least 21 days after surgery, and are observed in more than 75% of asymptomatic patients [10].…”

The objective of this study was to describe CT findings and to determine the diagnostic value of CT in diagnosis of acute mediastinitis. CT findings were retrospectively studied in 40 patients with suspected acute mediastinitis, including 28 postoperative patients, five with acute descending necrotizing mediastinitis (ADNM), and seven with suspected post-traumatic perforation of the esophagus. Findings included increased attenuation of mediastinal fat (100%), localized mediastinal fluid collections (55%), free gas bubbles in the mediastinum (57.5%), mediastinal lymph nodes (35%), pericardial effusions (27.5%), pleural effusions (85%), lung infiltrates (35%), sternal dehiscence (40%), and pleuromediastinal fistula (2.5%). The sensitivity and specificity of CT in postoperative patients in the first 17 days was 100% and 33% respectively, and after day 17, 100% and 90%. In patients with ADNM sensitivity was 100% while in patients with suspected esophageal perforation sensitivity and specificity were 100%. CT is a highly sensitive technique for the detection of mediastinitis of various causes. For the postoperative patients there is clear time dependence for CT interpretation and accuracy. In patients with suspected ADNM, and traumatic esophageal perforation CT is highly specific early after clinical presentation.

“…Although the incidence is reported at 0.4%-5.0%, mortality is quite high, ranging from 12% to 50%, depending on the extent of the infection. [1][2][3][4][5][6][7][8][9][10][11] Previous computed tomography (CT) analyses in the setting of mediastinitis [1][2][3][4][5][6][7][8]12,13 have suggested that the primary hallmarks of mediastinitis include mediastinal fl uid collections and/or free gas bubbles. However, the same fi ndings have been made in normal patients after cardiovascular surgery, particularly during the early postsurgical period.…”

“…Its risk factors include obesity, diabetes, chronic obstructive pulmonary disease, chronic cough, steroid therapy, and internal mammary artery grafts [38]. Common CT findings in sternal osteomyelitis include bone destruction with demineralization and dehiscence [39]. Because aseptic hematoma or fluid collection in the mediastinum can be seen 2-3 weeks after sternotomy, it is not always easy to differentiate normal findings from those of infectious mediastinitis and abscess formation [40].…”

Aortic valve replacement is one of the most common major cardiac surgeries worldwide. Despite improvements in surgical techniques, postoperative complications after aortic valve surgery remain a source of substantial morbidity and mortality. Although transthoracic echocardiography and transesophageal echocardiography have been used for routine surveillance of prosthetic heart valves, computed tomography (CT) has played an important role with echocardiography in the diagnosis, treatment, and follow-up of patients after valve replacement. CT has the advantage of evaluating the extent of disease, such as paravalvular dehiscence, abscess, and pseudoaneurysm, in aortic prosthetic valves. In this article, we review the various image findings of postoperative complications after aortic valve replacement detected on CT.
