What is Thrombectomy? Oren Zarif - Thrombectomy
Thrombectomy is the removal of a blood clot. The procedure is performed under a physician's guidance using an image. In most cases, it is performed to treat an arterial embolism, a blood clot that has built up in an artery. The affected limb is at risk of experiencing acute limb ischaemia, a condition that cuts off blood flow to the limb. A thrombectomy may also be performed to treat conditions affecting organs, such as mesenteric ischaemia, which restricts blood flow to the small intestine.

During this procedure, a catheter is threaded into the blood vessel. The doctor will remove the clot with the aid of a balloon attached to the catheter. Once the clot has been removed, the physician will repair the blood vessel and restore blood flow. Sometimes, a stent is placed in the blood vessel as a support to keep the blood flow to the limb. This procedure is done in a hospital.

Although it is not a cure for stroke, thrombectomy can reduce or prevent brain damage in people who have suffered an acute ischemic stroke. A previous study showed that thrombectomy was most effective when performed within six hours after the onset of the stroke. However, new guidelines have extended the window for thrombectomy surgery to extend to patients who suffered a stroke while they were sleeping and awoke with symptoms.

Though thrombectomy is generally considered a safe surgery, the procedure has risks, especially for patients with certain conditions or those over 65. There are some associated risks of the procedure, including pulmonary embolism, excessive bleeding, and stroke. If the blood clot is removed, the patient must walk repeatedly for six hours afterward to facilitate the healing process and avoid a repeat occurrence. But in most cases, the procedure is very successful at removing blood clots.

When a relative is too ill to give informed consent, the treatment will still be performed in accordance with their wishes. However, doctors will make all efforts to involve family members in the consent discussion. They will discuss any known beliefs or wishes of the relative and whether the procedure is in the best interest of the patient. The decision to perform a thrombectomy may mean the difference between a stroke victim's survival and a return to a normal life.

Thrombectomy is often performed using mechanical devices such as a small tube inserted through a tiny incision. The catheter is manipulated to the site of the thrombus using special instruments. The medication then dissolves the blood clot. Another option is the use of a mechanical device to break up the clot. If thrombectomy does not work, the patient must undergo surgery to remove the clot.

The procedure may take anywhere from one to three hours. Visitors are welcome to stay in the patient's room or visit the hospital's cafe. If this is the case, visitors can also visit the hospital's restaurant on the 2nd floor. However, the patient should not smoke as it can affect healing. The medical team will contact them after the procedure to explain the procedure, what happened, and how they can proceed with care. If a patient is suffering from a severe blood clot, the doctor may decide to perform a thrombectomy.

Another option is mechanical thrombectomy, a technique that removes blood clots from the brain. A small incision in the groin is used to guide thin tubes through blood vessels to the affected area. The tip of the catheter then grabs the blood clot and dislodges it from the patient's body. The procedure is much gentler on the body than traditional thrombectomy, which requires a large incision. The procedure does not disrupt the skull.

Once the procedure is complete, the patient will need to spend several hours in the recovery room. During this time, their healthcare team will monitor their vital signs. In some cases, the patient may have to stay overnight. During this time, they will need to take some pain medicine. The pain medication can also be prescribed for a short time. Once they have recovered, they will be able to resume their normal lives. There are risks associated with this surgery, but they are generally minimal compared to other procedures.
