According to our findings, a family history of cancer increased the risk of CRC. Due to this fact that there is no current colorectal cancer screening program in Iran, it is recommended that first degree relatives of patients with colorectal cancer should be considered as a priority group for screening programs.
A 31-year-old female who had well-established polycythemia vera one year before, presented with the sudden onset. She had severe ascites and hepatic encephalopathy 12 d prior to admission. Real-time ultrasonography revealed a supra hepatic thrombosis extending toward the inferior vena cava (lVC). Thrombolytic therapy with systemic streptokinase (250000 IU loading + 100000 IU/h infusion) was started. At the end of 72 h infusion, the patient's general condition improved. A color Doppler ultrasonography then showed complete and partial resolution of the thrombosis in the supra hepatic vein and IVC, respectively. Despite this good response, 12 d later, the symptoms recurred. Venography detected complete obstruction of the lVC. Percutaneous balloon angioplasty with stent insertion was performed successfully and the patient was discharged without any evidence of liver disease. A combination of systemic streptokinase and radiological intervention was effective in our patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
