Introduction
Inferior vena cava thrombosis (IVCT) is a rarely seen clinical
condition. It is an under-recognized entity which is associated with
significant morbidity and mortality.1 It is estimated
about 2.6 to 4.0 percent of patients with lower extremity deep vein
thrombosis (DVT) have IVCT.2-5 Our patient here was a
congenitally normal person who didn’t have any etiology of prothrombotic
factors or abdominal pathology. The only peculiar observation was that
he had an elevated serum homocysteine level. Although, previous study
has shown elevated homocysteine concentration found in 40 percent of
patient with vascular disease and 35 percent of patient with venous
thromboembolism.6 However, high levels of homocysteine
in the absence of any other etiology is a rare phenomenon.
We describe a case of a congenitally normal 78-year-old male with
hyperhomocysteinemia with a left leg DVT extended towards the IVC. The
patient was treated with an anticoagulant and was supportively
discharged.
