More rarely, hematoma can result from breast biopsy. Rarely, a breast hematoma can also occur spontaneously due to a rupture of blood vessels in the breast, especially in persons with coagulopathy [1] [2] or after long-term use of blood-thinning drugs such as aspirin or ibuprofen. [3]
This is composed of blood plasma that has seeped out of ruptured small blood vessels and the inflammatory fluid produced by injured and dying cells. [citation needed] Seromas are different from hematomas, which contain red blood cells, and abscesses, which contain pus and result from an infection. Serous fluid is also different from lymph.
A hematoma, also spelled haematoma, or blood suffusion is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery [1] and may involve blood continuing to seep from broken capillaries.
Breast ultrasound is also used to perform fine-needle aspiration biopsy and ultrasound-guided fine-needle aspiration of breast abscesses. [8] Women may prefer breast ultrasound over mammography because it is a painless procedure and does not involve the discomfort of breast compression present in mammograms.
Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" (see Venous hypertension section below). When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles.
An embolism involves the occlusion of blood vessels by an embolus. [1] Arterial occlusion by an embolus is termed 'arterial embolism'. An embolus is an agent that blocks blood flow by physically obstructing blood vessels. [1] This includes gas bubbles, [18] fatty deposits, amniotic fluid, [19] blood clots, and foreign material. Arterial emboli ...
Also, blood clots may form on the inside of ventricular aneurysms, and form embolisms. If such a clot escapes from the aneurysm, it will be moved in the circulation throughout the body. If it gets stuck inside a blood vessel, it may cause ischemia in a limb, a painful condition that can lead to reduced movement and tissue death in the limb. [1]
By contrast, the blood itself and the healthy muscular tissue portion of the blood vessel wall is relatively echolucent, just black circular spaces, in the images. Heavy calcium deposits in the blood vessel wall both heavily reflect sound, i.e. are very echogenic, but are also distinguishable by shadowing. Heavy calcification blocks sound ...
