Abstract

We present here the case of a 30-year-old man with a long term history of nephrotic syndrome (NS) who developed an episode of acute left main pulmonary artery thrombosis complicated by a lung abscess. During the hospital admission was also identified a concomitant hyperhomocysteinemia. After an atypical resection of the left upper pulmonary lobe and the starting of long term anticoagulation the patient was discharged but did not attend the planned follow up visits until one year later when he was seen again for severe dyspnea and exercise intolerance. At this time chronic thromboembolic pulmonary hypertension (CTEPH) was diagnosed by lung perfusion scintigraphy and right heart catheterization. He initially refused the surgical treatment but, after six months, for the presence of worsening dyspnea was referred for bilateral pulmonary endarterectomy followed by a cardio-thoracic rehabilitation program. After a follow-up of seven years the patient is alive and in stable conditions. NS and hyperhomocysteinemia are both known risk factors for pulmonary embolism (PE), but their association with CTEPH is extremely rare. We discuss here the possible mechanisms linking these conditions. CTEPH must be suspected in any patient with NS, with or without hyperhomocysteinemia, and unexplained dyspnea.

METRICS

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
