Preparation for the operation begins with a consultation with a surgeon. During the appointment, the doctor conducts an examination, clarifies complaints, assesses the size, location, and mobility of the hygroma, and also determines how long ago it appeared and whether it has changed over time.
To clarify the diagnosis and plan the operation, ultrasound diagnostics are most often prescribed. The examination makes it possible to determine the size, structure, and location of the hygroma, assess its connection with the joint or tendon, and plan the extent of the surgical intervention. In some cases, an X-ray may additionally be required, in particular to assess the condition of the joint or adjacent bone structures.
If surgical removal of a hygroma on the arm or leg is necessary, a standard preoperative examination is performed before the operation. It usually includes a complete blood count, coagulogram, general urine test, and other examinations, the need for which the doctor determines individually depending on the patient's health condition and the type of anesthesia.
