Image Guided Venous Sampling for the Localization of Endocrine Tumors

Figure 1. IPSS venography. Image shows microcatheters in both inferior petrosal sinuses (black arrows) after contrast injection from the left side, which opacified the contralateral sinus via mild reflux, indicative of proper catheter positioning. The black star indicates the expected location of the pituitary gland within the opacified cavernous sinus. Elevated levels of cortisol production re...

Comparison Between Open and Ultrasonography Guided Venous Access Ports in Children with Malignancy

Background: Long-term central venous access is used in children for various reasons specially for delivering chemotherapy. Since vessels in children have smaller diameters, they are more prone to injury and complications such as thrombosis. Different methods are used for implantation of port-a-cath in children. We aimed to compare the complications of insertion of central venous access ports be...

Ultrasound-guided central venous access

Central venous catheterization is a critical component of management for the critically ill patient in the operating room and intensive care unit. When using ultrasound techniques for central venous access, access is achieved with fewer attempts, a reduced incidence of carotid artery punctures or 'hits', an increased success rate, and a decreased duration of procedure compared to the traditiona...

Ultrasound-guided central venous access.

HYPOTHESIS Real-time ultrasound guidance should increase the success rate and lower the complication rate of central venous access in patients with relative contraindications to having the procedure performed. DESIGN Prospective case series. SETTING A community-based tertiary care hospital. PATIENTS Fifty-two patients were studied. Relative risks to central venous catheter insertion inclu...
