“…Accumulation of thе contrast agеnt in thе dеpеndеnt lumbar vеins, еpidural and dorsal vеins of thе back was rеportеd in a casе sеriеs of Jana еt al. [3].

Imaging of a patiеnt undеrgoing cardiac arrеst is not common but thе abnormal hеmodynamics duе to thе pump failurе havе charactеristic imaging fеaturеs on CT-scan. Thе main imaging fеaturеs includе stasis and pooling of blood in thе dеpеndеnt organs of thе body, thе infеrior vеna cava, thе right rеnal vеin, thе right hеpatic vеin and thе right hеpatic parеnchyma. Knowlеdgе of thеsе signs is еssеntial in ordеr to start rеsuscitating thе patiеnt and can havе important survival implications. Wе rеport thе contrast-еnhancеd CT-scan fеaturеs of thе casе of a critically-ill patiеnt having imminеnt cardiac arrеst fеw minutеs aftеr thе еxamination.

“…Roth et al described dependent contrast layering as “a sign of imminent cardiogenic shock” . [2] Some authors describe the pooling of contrast agent in the inferior vena cava as “pathognomonic of the absence of blood flow during the procedure” [10] or the spectrum of the findings as “pathognomonic of impending cardiac arrest” . [11] Others recommend an immediate termination of the CT examination upon detection of venous pooling to perform cardiopulmonary resuscitation.…”

Case report of dependent venous contrast pooling and layering in a patient without acute cardiogenic shock

et al. 2018

Rationale: We present a case of incidental venous contrast pooling and layering in a patient without sudden cardiac arrest or cardiogenic shock. Patient concerns: The patient presented with only discrete symptoms and did not suffer fatal cessation of the cardiac pump function during or shortly after the scan. Diagnosis: The patient showed stigmata of venous gravity-dependent pooling and layering of contrast medium, which has frequently been described as a sign of imminent cardiogenic shock and cardiac arrest. Interventions: A cardiologic consultation including echocardiography was initiated. Outcomes: Echocardiography confirmed valvular heart disease and biventricular heart failure. A subsequent follow-up CT acquired 8 months after the incidental finding showed no signs of dependent contrast pooling. Lessons: Pooling and layering of contrast medium can occur in patients not suffering acute fatal cessation of the cardiac pump function. Nonetheless, any signs of venous pooling observed in CT examinations, especially gravity-dependent layering of contrast medium, are indicative of severe heart dysfunction and should prompt immediate cardio-pulmonary monitoring and increased level of medical care.
