Muskelbiopsier

Muskelbiopsier, also known as muscle biopsies, are a medical procedure that involves removing a small sample of muscle tissue from a patient. The purpose of a muscle biopsy is to examine the muscle tissue under a microscope to diagnose and monitor various muscle disorders, such as muscular dystrophy and myopathies.

Before the procedure, the patient's ultrasound or CT scan is typically used to guide the Needle of the biopsy instrument, determining the best muscle to sample. A local anesthetic is administered to numb the area, and a needle or small incision is used to remove a small sample of muscle tissue, usually about 1-2 mm in diameter. The procedure is usually quick, lasting only a few minutes.

The removed muscle tissue is then analyzed in a laboratory under a microscope by a pathologist who examines the muscle fibers, muscle nuclei, and any other tissue components to identify any abnormalities. Muscle biopsies can help diagnose various conditions, such as muscular dystrophy, muscular atrophy, and muscle infarction (muscle death due to lack of blood flow). They can also be used to monitor the progression of muscle disease and to evaluate the effectiveness of treatment.

The risk of a muscle biopsy is relatively low, but as with any medical procedure, there are some potential complications. These include bleeding, infection, damage to surrounding nerves, and muscle weakness or pain at the biopsy site. The results of a muscle biopsy are usually available within a few days, and the findings may lead to further testing, such as imaging and other diagnostic tools, to confirm the diagnosis and develop an effective treatment plan.
