Some issues Dr. Christopher Gene Kalhorn, MD can help you with:

Hydrocephalus

Normally, the brain is bathed in a liquid called cerebrospinal fluid. This fluid cushions and nurtures the brain cells as it flows around and through the brain. Sometimes, cerebrospinal fluid does not get reabsorbed into the body properly, or a blockage in the brain can stop it from flowing. This causes a buildup of pressure called hydrocephalus. This condition affects a wide range of people, but it is much more prevalent among infants and older adults. Left untreated, hydrocephalus can cause uncomfortable symptoms, such as headaches and blurred vision, and eventually may cause brain damage.

Hydrocephalus is most often treated with an implanted device called a shunt. A shunt is a long, thin tube that is used to drain excess fluid. One end is placed within the brain. The tube runs under the skin, along the neck behind the ear, and to another part of the body where the fluid can be reabsorbed. Most often this is the abdomen, but the chest or other areas can also be used. Shunts have a valve that allows doctors to monitor and control the pressure within the brain. Insertion of a shunt is a surgical procedure that takes one to two hours. Incisions are made in the head and the abdomen, and the shunt is threaded into place before the openings are stitched closed.

In cases where hydrocephalus is caused by a blockage, a procedure called endoscopic third ventriculostomy, or ETV, may be performed. During this procedure, a surgeon makes a dime-sized hole in the skull and uses a thin tube with a camera on the end (called an endoscope) to see inside the brain. The surgeon punctures a hole in the floor of the third ventricle, a fluid-filled space within the brain. The hole provides an opening for cerebrospinal fluid to flow around the blockage, normalizing pressure. The entire procedure usually takes less than an hour and patients can often go home the following day. ETV can provide a permanent and safe alternative to a shunt, but it is only useful for patients whose hydrocephalus is caused by a blockage.

Intra-Aortic Balloon Pump (IABP) Insertion

High-risk patients whose hearts are not able to pump blood effectively may be fitted with a device called an intra-aortic balloon pump or IABP. This device is a temporary, surgically implanted pump that does some of the work of the heart and supports the heart in moving blood throughout the body. An IABP may be used after a heart attack, during heart surgery, for patients who are having trouble after a bypass, or as a "bridge" treatment for patients who are waiting for a heart transplant.

An intra-aortic balloon pump is a small, sausage-shaped balloon at the end of a catheter, or very thin, flexible tube. An incision is made (usually in the groin), and the deflated balloon and catheter are threaded through an artery to the aorta, the large main artery that takes oxygen-filled blood from the heart to the rest of the body. The pump can also be placed during open-heart surgery. If this is the case, it is positioned directly into the aorta. Once in place, the balloon inflates and deflates in rhythm with the heart. When it inflates, it pushes blood back towards the heart to help the heart muscle get enough oxygen and fill correctly. When the IABP deflates, just before the heart contracts, it lowers the pressure in the aorta slightly. This helps move blood away from the heart and into the body.

An IABP is a short-term solution, used for only hours or up to a few weeks at most. The pump is powered and controlled by a computer outside the body, so during treatment patients must remain lying down in their hospital bed. Insertion of the device is performed at a cardiac catheterization lab or operating room, and patients with an intra-aortic balloon pump often stay in the intensive care unit (ICU). While it is not a particularly painful treatment, it is common for patients to hear and feel the balloon inflating and deflating within their chest, which can be unsettling. However, IABP is a safe and effective treatment for supporting the heart.

Spinal Fusion

Spinal fusion is a surgical procedure to permanently join together two or more vertebrae, the bones in the spine. Certain spinal disorders can lead to instability and pain, and the idea behind spinal fusion is that fusing vertebrae together can both make them stronger and reduce motion, which can sometimes reduce pain.

There are several different types of spinal fusion surgery available, mostly depending on where a patient's pain is located and whether his or her surgeon will perform the procedure through the back, front, or side. In general, a fusion is performed by packing the vertebrae to be fused with grafted bone. This bone may be taken from the patient's hip, may be donated from a cadaver, or it may be a manufactured synthetic material. The bone is placed along the vertebrae, and sometimes, the disc that lies in between the vertebrae is removed and replaced with grafted bone. The bone material will grow and cement the two vertebrae together. After the bone graft is placed, the vertebrae are sometimes held in place with rods, screws, plates, or cages, depending on the weakness of the spine and needs of the graft.

Spinal fusion is a significant surgery and can take three to four hours or more. Recovery is typically two to four days in the hospital. After surgery, it is important to remember that the fusion takes time to grow from the bone graft. So, the actual fusion is not complete for several months. Patients will probably feel somewhat better right away, but it may take a while to feel the full effects of the fusion as the bone grows into place. In the meantime, doctors might have patients wear a brace to protect their spine and keep it properly aligned.

Spinal fusion is not used for all kinds of back pain. Changing the way the spine moves can lead to strain on the other joints in the back, and fusion is only performed when the benefits outweigh the risks. Some spine disorders that are treated with fusion include:

  • Curvature disorders, such as scoliosis and kyphosis
  • Degenerative disc disease
  • Spondylolisthesis, a disorder that causes vertebrae to slip over each other
  • Significant spinal fractures that cause instability
  • Weakened spine due to infection or tumor
  • Some cases of spinal stenosis, a narrowing of the spinal column
  • Chronic lower back pain (although the use of fusion to treat this is controversial)

Regardless of the diagnosis, there is always a possibility of 'failure' with spinal fusion, or of the surgery not fully solving the pain. This is more likely when fusion is used primarily to treat pain instead of structural problems. Patients can improve their chances of a successful outcome by stopping smoking, maintaining a healthy weight, moving their body every day, and following their doctor's instructions for any physical therapy that they are prescribed.
