Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
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 ...
When severe enough to cause these shifts and hypotension, it is called a tension pneumothorax. This is life-threatening. The increased pressure inside the chest can compress the heart and lead to a collapse of the blood vessels that drain to the heart. The veins supplying the heart are compressed, in turn decreasing venous return. [7]
Trousseau's syndrome is a rare variant of venous thrombosis that is characterized by recurrent, migratory thrombosis in superficial veins and in uncommon sites, such as the chest wall and arms. This syndrome is particularly associated with pancreatic, gastric and lung cancer and Trousseau's syndrome can be an early sign of cancer [ 2 ] [ 3 ...
Massive PE causing hemodynamic instability (shock and/or low blood pressure, defined as a systolic blood pressure <90 mmHg or a pressure drop of 40 mmHg for >15 min if not caused by new-onset arrhythmia, hypovolemia, or sepsis) is an indication for thrombolysis, the enzymatic destruction of the clot with medication. In this situation, it is the ...
An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel. [1] The embolus may be a blood clot ( thrombus ), a fat globule ( fat embolism ), a bubble of air or other gas ( gas embolism ), amniotic fluid ( amniotic fluid embolism ), or foreign material .
An embolus, is described as a free-floating mass, located inside blood vessels that can travel from one site in the blood stream to another. An embolus can be made up of solid (like a blood clot), liquid (like amniotic fluid), or gas (like air). Once these masses get "stuck" in a different blood vessel, it is then known as an "embolism."
