Atypical venous thrombosis and protein S deficiency: report of a case

A 29 year old man is admitted for hypovemic shock and abdominal pain. This critical condition was due to a diffuse mesenteric venous thrombosis and intestinal infarction. Five meters of small bowel are resected. Few days later a superficial brachial venous thromboembolism grows to superior cava venous and bilateral pulmonary embolism. A plasmatic protein S level was 17%. This deficiency is considered to be the support of these atypical extended and repetitive venous thromboembolism. With an optimal nutrition and long oral anticoagulation this patient is alive 17 months after his admission.
