introduction : activated protein c (apc) inactivates factor v by cleavage of its heavy chain at arg306, arg506, arg679, and lys994. mutational changes, which abolish apc cleavage sites, may predispose thrombosis by altering the inactivation process of factor v.  factor v leiden (arg506glu) has been demonstrated as a strong risk factor for thrombosis. in the current study, we have studied whethe...

background: central venous catheters (cvcs) have been used widely in clinics. these catheters are also recommended for children and infants receiving chemotherapy and total parenteral nutrition (tpn) and etc. in this paper, we present migrated fractured control line of the heart of a girl. case presentation: a 2.5 year old girl with migrated of the fractured central line into the heart. in the ...

introduction: the correlation of central venous pressure (cvp) with inferior vena cava (ivc) sonographic diameter has been reported in several studies. however, few studies have attempted to find the best anatomic location of measurement. therefore, the purpose of this study was determining the best anatomic location to find precise correlation between cvp and ivc diameter using transesophageal...

introduction: determining the proper angle for inserting central venous catheter (cv line) is of great importance for decreasing the complications and increasing success rate. the present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization.  methods: in the present case series study, candidate patients for catheterization of the right i...

conclusions in our study, portal venous thrombosis was detected in the patient who died during the acute period only. a study including large numbers of budd-chiari-syndrome patients with behcet’s disease and portal venous thrombosis would be helpful to determine the prognostic significance of portal venous thrombosis in budd-chiari-syndrome patients with behcet’s disease. in addition, patients...

recently, a number of procedures for interventional radiology diagnosis and treatment have been developed by the radiologists. the ‘interventional radiology’ refers to the therapeutic procedures performed under imaging guidance. the emergence of this specialty has been made possible by a lot of advances in the technology, imaging systems, and radiologists experience. interventional radiologists...

background: venous thromboembolism, which comprises deep vein thrombosis and pulmonary embolism and is a significant cause of morbidity and mortality among patients with cancer. the aim of the present study was to report a rare presentation of arterial thrombosis after venous thrombosis in a patient with gastric cancer. report of the case: a 45 year-old female patient with locally advanced gast...

ess the relationship between umbilical cord blood gases at birth and morphology of umbilical cord, in a prospective study of 200 consecutive term delivery, we investigated the relationship between umbilical cord morphology characteristics (umbilical crd length, number of vascular coil, coiling index) and color of amniotic fluid and umbilical vessel blood gases. statistically significant linear ...

background the presence of arterio-venous (a-v) fistula recirculation among hemodialysis (hd) patients markedly decrease adequacy of dialysis. objectives the present article summarize some of observations about clinical significance, causes, the most common techniques for measurement, and main source of pitfall in calculation of access recirculation. materials and methods a variety of literatur...

Herein, we report a patient with arterio-venous fistula secondary to mycotic aneurysm, causing high output heart failure. The patient had one-year history of refractory heart failure and recurrent pulmonary edema. This presentation is a good example of curative surgically treatable cause of high-output congestive heart failure.Iran J Med Sci 2005; 30(1): 41-44. Keywords ● Arterio-venous fistula...
