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]
Fine-needle aspiration is a common procedure. [1] However, it is controversial: [ 11 ] it is recommended by some for the reason that a seroma can be a culture medium for bacteria, [ 12 ] whereas others advise it only for collection of excessive amounts of fluid, because even an aspiration carried out under aseptic conditions carries a certain ...
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.

The body is 73% water, and therefore, acoustically homogeneous. Blood and surrounding tissues have similar echogenicities, so it is also difficult to clearly discern the degree of blood flow, perfusion, or the interface between the tissue and blood using traditional ultrasound. [4] Ultrasound imaging allows real-time evaluation of blood flow. [29]
The first surgical treatment is thought to be performed by R.S. Shaw and described in the New England Journal of Medicine in 1958. The procedure Shaw described is referred to as mesenteric endarterectomy. [18] Since then, many advances in treatment have been made in minimally invasive, endovascular techniques including angioplasty and stenting.
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.
The sound waves are emitted from the catheter tip, are usually in the 20-40 MHz range, and the catheter also receives and conducts the return echo information out to the external computerized ultrasound equipment which constructs and displays a real time ultrasound image of a thin section of the blood vessel currently surrounding the catheter ...
