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.
