interventional radiology

Interventional radiology is one of the specialized branches of radiology that diagnoses and treats the patient with the help of CT scan, ultrasound, MRI, fluoroscopy and special techniques and the necessary expertise and skill of the doctor.

This technique can be performed easily and without surgery by making a small incision on the skin, and as a result, it has much fewer side effects.

The following services are provided at RROC:

Biopsy :

One of the most accurate methods of tumor diagnosis is a needle biopsy, which is taken from a tissue or lesion (liver, soft tissue, breast, thyroid, etc.) with the guidance of imaging devices under local anesthesia and sent to pathology for diagnosis

Evacuation of all types of cysts

Abdominal, ovarian, breast, liver, etc. cysts are sent to the laboratory for evacuation and cytology under the guidance of an imaging device with local anesthesia.

Amniocentesis

Amniocentesis is the breathing fluid around the fetus for prenatal diagnosis and is performed under the guidance of an ultrasound machine. It is recommended to be done between 14 and 18 weeks of pregnancy.

Nephrostomy

Placing a special catheter inside the kidney system to divert the urinary tract in patients with ureteral obstruction, which is performed under the guidance of ultrasound and fluoroscopy with local anesthesia. Catarenephrostomy should be avoided.

Fetal placenta sampling

Sampling of fetal placental villi is to detect genetic abnormalities before birth, which is recommended between 11 and 14 weeks of pregnancy. This sampling is done under the guidance of an ultrasound machine with local anesthesia.

Sclerotherapy

The collection of scattered and irregular thin capillaries on the surface of the lower limbs, which are not suitable for beauty, are treated by injecting sclerosing drugs into these veins.

Abscess drainage

Catheterization of abdominal, pelvic, etc. abscesses is performed under the guidance of the imaging device with local anesthesia in order to remove the abscess and infection, and it is connected to the bag by an interface and placed in the drain. This catheter is fixed on the skin by suture thread and fixator so that the catheter does not come out. After complete drainage of the abscess and imaging for complete certainty, the catheter is removed from the body.

Drainage of bile

In patients whose bile duct obstruction causes jaundice and itching, a special catheter is placed in the path of the obstruction under the guidance of an imaging device with local anesthesia. In cases where severe obstruction makes it impossible to pass the catheter through the stricture, the end of the catheter is connected to the bag and the bile is directed out of the stomach, to prevent the accumulation of bile in the bile ducts.

Radio frequency (RF):

Radiofrequency is a treatment method in which, under ultrasound guidance, a needle electrode is inserted through the skin near the mass (liver, kidney, lung, breast, etc.). Passing high-frequency electric current creates a lot of heat and destroys cancer cells. In this method, lumps smaller than 1.5 inches, which are difficult to remove with surgery, are completely cured in more than 85% of cases.

Breast mass marker:

Some breast lumps are not easily accessible during surgery. In this case, the radiologist finds the lump under the guidance of the imaging device and places a very thin spring inside the lump. The other end of this spring is placed outside the skin of the breast so that the surgeon can easily remove the mass.

Breast  FNA

The simplest and fastest method of breast sampling, which is with a very weak needle (size 22 or 25) and syringe, cyst fluid or a number of suspicious tissue cells are removed through the skin with ultrasound guidance and sent to the pathology laboratory for examination.

Thyroid  FNA

The easiest way to check whether a thyroid nodule is cancerous or not is to suction a few suspicious tissue cells with very weak FNA needles under ultrasound guidance.
