Multiple pulmonary thromboembolism and severe depression.
General Hospital Psychiatry 2010 September
INTRODUCTION: Depression is known to have a bidirectional relationship with cardiovascular disease. Severe major depression associated with psychomotor retardation and immobility can be a risk factor for pulmonary embolism; the reverse pathway has not been reported.
CASE REPORT: We report a case of a 61-year-old man diagnosed with multiple pulmonary thromboembolism finally attributed to a right pulmonary artery intraluminal sarcoma. One month after the onset of presenting symptoms, the patient suddenly developed an episode of severe, melancholic depression, which remitted in six weeks under treatment with venlafaxine 225 mg/day.
DISCUSSION: Pathophysiological mechanisms implicated in the development of depression in our patient might resemble those postulated for post-myocardial infarction depression; in line with the "vascular depression" hypothesis, cerebral damage in the limbic circuitry caused by transient hypoxia, an inflammatory response or both may have contributed.
CONCLUSION: Multiple pulmonary thromboembolism seems to have a bidirectional relationship with major depression, in a similar way as myocardial infarction does.
