A targeted puncture is a method used in medicine to obtain a sample of tissue or fluid from the body. It consists of inserting a needle through the skin, which then moves deep into the tissue until the desired point is reached.
When performing a targeted puncture, the patient is in a supine position. The doctor treats the needle insertion site with an antiseptic and numbs it. He then inserts a needle into the skin and advances it deeper into the tissue under vision control using special equipment such as an ophthalmoscope or ultrasound system.
During the procedure, the doctor makes sure that the needle does not pass through vital organs or vessels. If this happens, the procedure is interrupted and the needle is removed. Once the needle has reached the desired point, the doctor removes it and removes the resulting tissue or fluid sample from the body.
Targeted puncture is one of the most common methods for obtaining tissue or fluid samples for diagnosing various diseases. It provides more accurate results than other methods such as biopsy or surgery. However, like any medical procedure, targeted puncture has its risks, such as damage to blood vessels or nerves, so before performing it, it is necessary to conduct thorough preparation and choose an experienced doctor.
Puncture biopsy is one of the methods for the primary diagnosis of tumors and tumor-like processes. The manipulation is usually performed under local anesthesia on an outpatient basis or endoscopically under general anesthesia, less often under spinal anesthesia. At its core, it belongs to the class of diagnostic routine interventions (routine investigations), carried out in general surgical patients to diagnose tissue damage to organs of a particular location.
Puncture biopsy is an alternative to invasive methods of primary diagnosis - incisional and excisional biopsy. Unlike the latter methods, they do not require significant traumatic effects on organs and tissues; shorter execution time; are cheaper to perform and more effective, since they allow, as a rule, to extract pathological tissue in a “living” state and deliver it along with the puncture object to a histological laboratory.
