OBJECTIVE The objective of our study is to assess the correlation between inferior vena cava (IVC) diameters, central venous pressure (CVP) and the IVC collapsibility index for estimating the volume status in critically ill patients. METHODS This cross-sectional study used the convenient sampling of 100 adult medical intensive care unit (ICU) patients for a period of three months. Patients ≥ ...

Laparoscopy has become a standard modality for most renal tumors but not as yet for renal cell carcinoma (RCC) involving the inferior vena cava (IVC). Robotic technology may facilitate such complex procedures. We report the first series of robotic nephrectomy with IVC tumor thrombectomy including the first cases requiring cross-clamping of the IVC in a minimally invasive fashion. Five patients ...

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...

Recognition of azygos continuation of the inferior vena cava (AC-IVC) is necessary to prevent unnecessary surgery, to modify the approach to right heart catheterization and to avoid potentially fatal azygos ligation at the time of thoracic surgery. Absence of the inferior vena cava (IVC) shadow on the lateral chest film has been claimed to be an important feature of AC-IVC. Our findings, howeve...

A case of the Budd Chiary Syndrome (BCS) in a 43-yr-old man with hydatid cyst (HC) in the liver is reported from Imam Ali Hospital, Kermanshah, western Iran in 2016. This case was complicated by inferior vena cava (IVC) thrombosis, right atrial clot and pulmonary emboli. Compression of IVC was the likely mechanism. Abdominal ultrasonography revealed a huge HC located in segments near IVC and ca...

OBJECTIVE To review the outcome of resection of the suprarenal or infrarenal inferior vena cava (IVC) and possible indications for prosthetic replacement. SUMMARY BACKGROUND DATA Involvement of the IVC has long been considered a limiting factor for curative surgery for advanced tumors because the surgical risks are high and the long-term prognosis is poor. Prosthetic replacement of the IVC is...

BACKGROUND Regular intake of vitamin C/ascorbate reduces blood pressure (BP) in hypertensives. High-dose intravenous vitamin C (IVC) achieves higher plasma levels; however, there is a paucity of research on acute BP effects. Our study is the first to investigate the effect of high-dose IVC, with or without concomitant i.v. nutrients, on BP during i.v. METHODS A cohort of adult patients schedu...

OBJECTIVE: To evaluate the respiratory systems of male and female rats maintained in individually ventilated cages (IVCs) from birth until adulthood. METHODS: Female Wistar rats were housed in individually ventilated cages or conventional cages (CCs) and mated with male Wistar rats. After birth and weaning, the male offspring were separated from the females and kept in cages of the same type ...

Assessment of respirophasic diameter fluctuations of the inferior vena cava (IVC) is detrimentally affected by its concomitant displacements. This study aims at presenting and validating a method to compensate for IVC movement artifacts while continuously measuring its diameter in an automated fashion (with minimal interaction with the user) from a longitudinal B-mode ultrasound (US) clip. Perf...

BACKGROUND The prognosis of advanced liver malignancy with inferior vena cava (IVC) thrombi is poor. Many therapeutic policies are challenging for long-term prognosis. We performed the modified effective technique of transdiaphragmatic intrapericardial IVC isolation for curative resection of IVC tumors and prolonged survival time. METHODS Between 2003 and 2015, 10 patients, sustained liver ma...
