Aortic valve stenosis Aortic valve stenosis is a clinical picture of the heart in which the aortic valve is narrowed. In medicine, it is often referred to as aortic stenosis. The causes of aortic valve stenosis vary with age. Most often, calcification of the valve occurs in older patients. If the stenosis occurs in younger … Aortic valve stenosis | Diseases of the aorta
Aortic Arch Syndrome Aortic arch syndrome is a narrowing of several or all branches of the aortic arch. The aortic arch itself can also be narrowed (stenosed). The main cause is vascular calcification. Sometimes an autoimmune disease (Takayasu arteritis) is also found as a cause. The symptoms depend on the degree and location of the … Aortic Arch Syndrome | Diseases of the aorta
Diagnostics and therapy A catheter that is inserted into the vena cava (vena cava) up to the right atrium can be used in diagnostics to assess cardiovascular function (cardiovascular system). In addition to measuring this central venous pressure (CVD), the catheter is also used for infusion therapy, which supports infusion therapy through peripheral intravenous catheters. … Diagnostics and therapy | Vena cava
Synonyms vena cava : vena cava Definition The vena cava (vena cava) is a large blood vessel that has the task of collecting blood in the body and returning it to the heart. It is divided into an upper and a lower part. The vena cava opens into the right atrium. Classification The vena cava … Vena cava
Function The vena cava has the task of collecting blood from the periphery of the body and returning it to the heart. It is also jointly responsible for filling the right heart. The pressure in the vena cava is between 0 and 15 mmHg. The pressure shows respiration-dependent and pulse-synchronous fluctuations, which is known as … Function | Vena cava
Definition Venous valves (valvulae) are structures in the veins that perform a valve-like function and thus prevent the blood from flowing back in the wrong direction. The wall of blood vessels is formed by three different layers. On the outside is the so-called tunica externa (adventitia), in the middle is the tunica media (media) and … Venous valve
Introduction The term venule refers to a section of blood vessels in the body’s vascular system which, together with the arterioles and capillaries, form the final flow path of the vascular system. The function of the venule includes the exchange between blood and tissue and the transport of blood as part of the vascular system. … Venole
Difference between a venule and an arteriole An arteriole is also a component of the final flow path of the vascular system and resembles an artery in its wall structure. The arteries generally have a larger and more compact muscle layer than the veins. The arterioles form the resistance vessels in the body’s circulation and … Difference between a venule and an arteriole | Venole
