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...

UNLABELLED We present a rare complex variation of the inferior vena cava and internal iliac veins demonstrated by a multidetector computed tomography. It was shown that patient had double inferior vena cava with azygos continuation of the right inferior vena cava, retroaortic left renal vein and the left and right internal iliac veins converged and drained to the right external iliac vein throu...

Extensively distended and tortuous vessels on both sides of the uterus are rare incidental findings on transvaginal sonography in early pregnancy. A 31-year-old woman with a history of surgical repair for congenital intestinal stenosis was noted to have utero-ovarian varices on a transvaginal ultrasound examination during her first prenatal visit at 6 weeks' gestation. Magnetic resonance imagin...

Congenital agenesis of the inferior vena cava is an uncommon congenital anomaly which can be misdiagnosed. Agenesis of the inferior vena cava has an incidence of 0.0005% to 1% in the general population [1]. The most common cause of agenesis of the inferior vena cava is the failure of embryological development between the sixth and the tenth weeks of gestation. Heterotaxy syndrome is associated ...

Venocaval anomalies are uncommon in the general population and often go unrecognized, but physicians should be aware of their significance. Duplicate superior vena cava should be identified during cardiac imaging, surgery, and catheter insertions. While interrupted inferior vena cava can predispose to thrombus formation, they protect against pulmonary embolism from lower extremity deep vein thr...

objective: to evaluate the feasibility and results of using serosal patch of small bowel for repair and replacement of inferior vena cava (ivc) after resection of a part of infra-renal ivc in an animal model, as it may be encountered in extensive tumors of retroperitoneal and trauma patients. methods: five healthy sheep of both sexes were prepared. after general anesthesia and laparotomy, a def...

While there is some local variability in the use of inferior vena cava filters and there has been some evolution in the indications for filter placement over time, inferior vena cava filters remain a standard option for pulmonary embolism prophylaxis. Indications are clear in certain subpopulations of patients, particularly those with deep venous thrombosis and absolute contraindications to ant...

atrial septal defect (asd) is a common congenital anomaly that has low surgical mortality and morbidity. we report a very rare case of a low-lying asd, combined with the drainage of the inferior vena cava and the left superior vena cava into the left atrium. this combination was associated with an unroofed coronary sinus. we also describe an iatrogenic surgical diversion of the inferior vena ca...

OBJECTIVE The objective of this study was to evaluate the feasibility of using carbon dioxide (CO(2)) as a contrast agent in performing bedside inferior vena cavagrams before the insertion of vena cava filters. There was a consecutive series of patients undergoing bedside preinsertion cavagrams with inferior vena cava filter insertion. The setting was an 825-bed tertiary care hospital. The subj...

adrenocortical carcinomas (acc) is an uncommon disease that accounts for only 0.02% of all cancers. herein, this study evaluates a case of adult acc with extension into the inferior vena cava and cushingoid features. a 67-year-old lady was admitted to the surgery service for surgical resection of adrenal mass which was found on hypertension work-up. on physical examination, she was fat, cushing...
