Changes of Oxygen Saturation in Inferior Vena Cava (IVC) in Patients During and After High Risk Abdominal Surgery and Relationship to the Outcome
Tissue hypoxia is one of the most important factors leading to the development of multiorgan failure. Patients presenting for emergent major abdominal surgery might suffer from organ hypoperfusion. Thus, early detection of the imbalance between oxygen supply and demand may improve the outcome. The investigators believe that hypoperfusion of the abdominal organs will cause a decrease of the saturation in the hepatic vein and in the IVC.

Catheterization, Central Venous
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
Abdominal Wound Closure Techniques
Methods to repair breaks in abdominal tissues caused by trauma or to close surgical incisions during abdominal surgery.
Central retinal vein and its tributaries. It runs a short course within the optic nerve and then leaves and empties into the superior ophthalmic vein or cavernous sinus.
A short thick vein formed by union of the superior mesenteric vein and the splenic vein.
Insertion of a catheter into a peripheral artery, vein, or airway for diagnostic or therapeutic purposes.
To test the hypothesis that approaching the internal jugular vein with the needle bevel down would produce less injury to the vessel wall compared to the bevel up approach during central v...
To evaluate the effect of a 2-stage approach to the internal jugular vein when performing a central venous catheterization compared to the traditional one stage approach on the incidence o...
Natural evolution of severe central retinal vein occlusion with low visual acuity is very poor. A randomized clinical trial will compare troxerutin and platelet anti-aggregating agents (dr...
Objectives: 1. To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound....
To determine whether photocoagulation therapy can help prevent iris neovascularization in eyes with central vein occlusion (CVO) and evidence of ischemic retina. To assess whether grid-pa...
The subclavian vein (SCV) is often the preferred site for long-term central venous catheterization in children. It has many advantages over the internal jugular vein. But with the classical landmark t...
ABSTRACT: Since the introduction of central venous catheterization for monitoring of the venous pressure, fluid infusion and hyperalimentation, the literature has been full of serious life-threatening...
BACKGROUND: Central venous catheterization is increasingly performed as a temporary vascular access for hemodialysis therapy in developing countries and it can be associated with serious complications...
To determine prevalence of central vein stenosis following catheterization with double-lumen temporary catheters, we performed color Doppler sonography in 100 consecutive patients. We detected central...
We present a case of the successful repair of an iatrogenic central vein lesion using a videothoracoscopic approach. The confluence of the right innominate vein and the superior vena cava was perforat...
