What is a cerebral angiogram?

A cerebral angiogram is a diagnostic procedure that can reveal any problems with the blood vessels in your brain. Specially trained healthcare providers perform this procedure in an operating room.
During the procedure, a healthcare provider inserts a catheter (thin plastic tube) into an artery in your wrist or groin area. They then inject a contrast agent (a special dye) through the catheter to show the structure of your blood vessels. Then, your doctor takes an X-ray of your blood vessels while you lie on the procedure table.
Cerebral angiograms can provide much more detailed images of these blood vessels than other imaging tests, such as CT (computed tomography) or MRI (magnetic resonance imaging) scans.
Cerebral angiograms are also called digital subtraction angiography (DSA) of the brain.

Osteoid osteoma ablation

Osteoid osteoma is a benign tumor of the bone and constitutes 10% of benign bone tumors. It is more common in the childhood age group. It is 2-3 times more common in boys than in girls. It usually involves long bones (tibia, femur, arm bones). Today, the preferred treatment method for osteoid osteoma is radiofrequency and microwave ablation. In radiofrequency and microwave ablation, a thin needle is entered into the tumor and heat energy destroys both the tumor and the nerve endings that cause pain. The procedure is performed through a needle hole under the guidance of tomography. There is no incision or stitching. The patient is discharged one day after the procedure.

Thyroid nodule ablation

Thyroid nodule ablation is the process of entering the thyroid gland with needles and destroying the nodule through heat. The procedure is usually performed under local anesthesia and as an outpatient. It has lower complication rates than classical surgery.

Subcutaneous Port Placement

A subcutaneous port is a medical device and is generally used in diseases that require long-term treatment. These ports are often preferred, especially in cases such as chemotherapy or long-term drug treatments. Its function is to protect the patient's vascular access and avoid frequent intravenous (venous) access.

The subcutaneous port is usually placed under the chest area. This port, placed under the skin through a surgical or minimally invasive procedure, consists of a reservoir and a catheter. The reservoir serves as an area where medications or other liquid substances are injected or removed. The catheter is a thin tube that connects the port's reservoir to a main vein.

Placement of the subcutaneous port is usually done under local anesthesia. During the surgical procedure, a pocket is created under the skin and the port is placed there. This procedure ensures that the patient's vascular access remains intact throughout the treatment process and can reduce problems caused by frequent intravenous interventions.

Care and use of the port is usually taught by healthcare professionals, and the patient may need to be checked at regular intervals.

Anterograde ureteral stenting is a medical procedure used when there is a blockage or narrowing of the urinary tract, called the ureter. The ureter is a thin tube that carries urine from the kidneys to the bladder. In case of blockage or narrowing in the ureter, urine flow may be blocked and negative consequences may occur in the kidneys.

Anterograde ureteral stenting is usually necessary for the following situations:

Ureteral Obstruction or Narrowing: Blockages or narrowings in the ureter due to reasons such as stones or tumors can block the flow of urine. In this case, stenting may be necessary to open the ureter and allow urine flow.
Complications After Surgical Intervention: After some urological surgical procedures, narrowing or obstruction of the ureter may occur. In this case, stenting can be performed.

Anterograde ureteral stenting is usually performed as follows :

Stent Placement: A stent, a thin tube, is placed into the ureter to relieve the blockage or open the narrowing. The stent ensures that the urinary tract remains open so that urine flow from the kidney to the bladder continues.
Inspection and Maintenance: The stent can usually be removed or replaced after a certain period of time. After placement of the stent, the patient is monitored and, if necessary, other problems in the urinary tract are treated.

Anterograde ureteral stenting is a procedure performed by interventional radiologists and is an important treatment option to restore healthy function of the urinary tract.

Installation of Tunneled Dialysis Catheter

Tunneled dialysis catheter is a type of catheter used in patients requiring long-term dialysis treatment. Insertion of this catheter should be under local anesthesia and imaging guidance and should be performed by interventional radiologists or doctors experienced in relevant fields.

The process of inserting a tunneled dialysis catheter usually includes the following steps:

The patient's general health condition is evaluated and necessary medical preparations are made.
The procedure area (usually the neck or groin area) is numbed with a local anesthetic.
A surgical cut is made in the anesthetized area. This cut is usually small and large enough for the path through which the catheter will be passed.
A tunnel is created to pass the catheter between the lower layers. This reduces the movement of the catheter under the skin and the risk of infection.
The catheter is placed through the created tunnel and its ends are generally directed to large veins.
The catheter is fixed to the skin so that it remains in place. This is usually done using stitches or special adhesive tapes.
After the procedure is completed, it is checked whether the catheter is working correctly and the patient is given necessary care instructions. During the healing process, the catheter and its surroundings are checked regularly and precautions are taken against the risk of infection.

This procedure may vary depending on the patient's general health condition and the condition of the vein where the catheter will be placed. It is especially important to use sterilization and appropriate surgical techniques to reduce the risk of infection.
