The purpose of this study is to evaluate the safety and effectiveness of the peripheral IV continuous infusion without the insertion of central venous vascular access method in the achievement of steady-state maximal coronary hyperemia compared with the central IV continuous infusion method.

This study was designed to examine if venous saturations from the central venous line and from the venous side of the heart lung machine are interchangeable or not with mixed venous satura...
Total of 89 patients undergoing elective cardiac surgery will be enrolled. Right CVC insertion begins at their intersection of the cricoid cartilage level and the triangular point where t...
In patients admitted to a coronary care unit, what is the correlation coefficient and limits of agreement for paired measurements of peripheral venous pressure and central venous pressure ...
Patients with cancer and an upper extremity DVT associated with a central venous catheter (CVC) will receive rivaroxaban. CVC survival will be assessed and compared to previous rates with ...
The purpose of this research study is to see if factor levels and inhibitor levels in Hemophilia A and B subjects are accurate when they are drawn from a central venous line (CVL) instead ...
The traditional technique of placing a peripheral intravenous (IV) catheter is successful in most cases on inpatient wards. However, when the traditional method fails, a central venous catheter may be...
Venous disease is more common than peripheral arterial disease. Pathophysiologically, venous disease can be associated with obstruction, reflux, or both. A common feature in chronic venous disease is ...
The insertion of a central venous line in children and adolescents is technically more difficult, due to the smaller size of the structures. This can lead to an increase in immediate complications, wh...
Venous access is essential in patients with haemophilia for administration of factor concentrates. Peripheral venipuncture may be challenging, particularly in young children or during immune tolerance...
Central venous catheters (CVC) can be useful for perioperative monitoring and insertion has low complication rates. However, routine post insertion chest X-rays have become standard of care and contri...
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
Rare vascular anomaly involving a communication between the intracranial and extracranial venous circulation via diploe, the central spongy layer of cranial bone. It is often characterized by dilated venous structures on the scalp due to abnormal drainage from the intracranial venous sinuses. Sinus pericranii can be congenital or traumatic in origin.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
