[4] [1] Although the hemostatic effect is greatly affected by the underlying disease, some high-volume centers report a hemostatic rate of about 90.4% within one year of treatment, and 85.9% even in two years after treatment. [2] The occlusion of the blood vessels in the brain, heart, and kidneys, which are supplied by the end arteries, can ...
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
Bronchial artery is considered dilated when its diameter is more than 2 mm. Several causes of bronchial artery dilatations are: congenital heart or lung diseases, obstructions of pulmonary artery, and lung inflammation. [1] The bronchial arteries are typically enlarged and tortuous in chronic pulmonary thromboembolic hypertension. [3]
Lung transplantation, or pulmonary transplantation, is a surgical procedure in which one or both lungs are replaced by lungs from a donor. Donor lungs can be retrieved from a living or deceased donor. A living donor can only donate one lung lobe. With some lung diseases, a recipient may only need to receive a single lung.
Vasodilators to relax and dilate blood vessels. [1] Appropriate drug treatments successfully produce thrombolysis and removal of the clot in 50% to 80% of all cases. [1] Antithrombotic agents may be administered directly onto the clot in the vessel using a flexible catheter (intra-arterial thrombolysis). [1]
The primary treatment for atherosclerosis is making lifestyle changes to help prevent the further build-up of plaque in your blood vessels. You may also need to take medications or receive a ...
Since the pulmonary resistance is proportional to the pressure driving the pulmonary flow (=), it follows that the pulmonary pressure decreases. This in turn means that the work per time (power) decreases because it is equal to the pressure gradient times the volumetric flow , which in this case is the cardiac output.
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
