A Case Report and a Descriptive Retrospective Study of Cases of Inferior Vena Cava Thrombosis Diagnosed over a 10-Year Period in a Third Level Hospital

Inferior vena cava thrombosis is an under-recognized entity associated with significant morbidity and mortality. This is the reason why, although the diagnosis is challenging, a high index of suspicion is required. Regarding this condition, we present the case of a 63-year-old man who had repeatedly visited the emergency room suffering from abdominal and back pain and painful lower limb edema. After several tests, including magnetic resonance imaging (MRI), he was diagnosed to have agenesis of left renal vein and inferior vena cava thrombosis, from hypercoagulable state secondary to Antiphospholipid Syndrome. He had anticoagulation treatment with low-molecular-weight heparin with good subsequent evolution. This study sets out a descriptive retrospective study of fifty cases of inferior vena cava thrombosis diagnosed in a third-level hospital in the north of Spain over a ten-year period (2010-2018). The aim of this article is to identify the epidemiology, predisposing factors and symptoms that characterize this entity, in order to be able to achieve an early diagnosis that allows us to initiate immediate treatment, minimizing acute and chronic complications of this disease.
