Some issues Dr. P. Gregory Gregory G. Hayes, MD can help you with:

Laparoscopic Surgery

Laparoscopic surgery is a kind of minimally invasive surgery using a thin, narrow tube called a laparoscope. Usually performed on the abdomen or the pelvic region, the surgeon makes a few very small incisions instead of one large one.

During the procedure, the surgeon inserts the laparoscope, which contains a light and camera that allows the surgeon to see what is happening inside the body. Then tiny tools are placed through the small openings and used to perform the surgery.

The most common laparoscopic surgery is gallbladder removal, but laparoscopic surgery may also be used for the removal of a kidney or appendix, to treat certain cysts and tumors, for bariatric surgery, for some GERD treatments, or for hernia repairs, among others.

Because laparoscopic surgery only uses a few tiny incisions, the scars are minimal and recovery is easier than with open surgery.

Peripheral Bypass Surgery

Peripheral bypass surgery is a procedure that reroutes blood flow around a blockage in the arteries of the arms or legs. Atherosclerosis, or plaque buildup, can affect these arteries in a condition called peripheral artery disease or PAD. A thick, waxy substance composed of cholesterol and minerals builds up within the blood vessels, and in severe cases it can clog arteries. Without enough blood getting to the muscles, patients can experience weakness and pain. Peripheral bypass surgery opens up a new pathway for blood to flow where it is needed. Sometimes peripheral bypass surgery is used when arteries are damaged, for instance, by a severe injury. While it can be performed in the arms, it is most commonly done in the calf, knee, thigh, or hip.

During surgery, the blockage is identified, and an incision is made to expose the artery. The surgeon prepares a tube, called a graft, to be used as the bypass. Sometimes this tube is synthetic, and sometimes a piece of the patient's own vein or artery is used. The ends of the bypass graft are attached to the artery above and below the blockage. Now blood can simply flow around and continue on its way.

After a peripheral bypass, patients may need to spend a couple of days in the hospital while doctors make sure the bypass is working and not leaking. If the bypass was done in the leg, doctors may check the pulse in the feet to make sure blood is flowing well. Patients may experience some swelling in the area where they had surgery. Raising an arm or leg will help. Patients will likely be back to normal activities within 2-3 weeks.

Stroke

A stroke is a medical emergency that occurs when a blood vessel supplying oxygen and nutrients to the brain is ruptured or blocked. The brain cannot function without a steady supply of oxygen and nutrients, so when the blood supply to the brain is interrupted, even for a brief moment, brain cells begin to die. When a sufficient number of brain cells die, the brain itself can no longer function, meaning that strokes are very dangerous. Strokes can result in impaired movement, speech, cognitive ability, the impairment of important physical functions, and even death.

Anyone can have a stroke, regardless of age and health. Strokes are known to happen at random. However, certain conditions and behaviors can increase one's risk of stroke over time.

Risk factors for stroke include:

  • Heart disease
  • Older age
  • Smoking
  • Diabetes
  • High blood pressure
  • High blood cholesterol and lipids

There are two main types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs more commonly and is when a blood vessel in the brain becomes blocked. Blockages are caused by blood clots and built-up plaque (deposits of fat and cholesterol), which leads to atherosclerosis, a condition where the blood vessels narrow and harden. The resultant restricted blood flow may lead to an ischemic stroke by blocking essential oxygen to the brain, causing the heart to exert more effort to pump blood.

Hemorrhagic stroke occurs when a blood vessel in or around the brain ruptures. The burst vessel leaks blood into surrounding brain tissue, causing irreparable brain damage.

Hemorrhagic strokes are less common and may occur from head injuries, brain aneurysms, brain tumors, and bleeding disorders, amongst other conditions.

Both ischemic and hemorrhagic strokes require immediate medical treatment. Medical intervention can prevent severe and life-threatening brain damage. Signs of stroke include:

-Disorientation or confusion

-Difficulty speaking

-Difficulty walking

-Impaired vision

-Weakness in the face, legs, or arms

-Severe headaches

When someone suspected of having a stroke reaches the hospital, the patient will usually receive a CT or other scan that provides an image of the brain. The scan results can reveal clotted or leaking blood in the brain. Physical exams, neurological exams, and blood tests may also be used to check for blood clotting and sugar. Treatment begins generally immediately if a stroke is detected.

Medical treatment for ischemic strokes includes a thrombolytic medicine which breaks up and disperses blood clots. This medicine can greatly improve stroke recovery and long-term health. However, the thrombolytic medicine must be administered as soon as possible to achieve these results. Other treatments for ischemic strokes are blood thinners and thrombectomy, a surgical procedure to remove a blood clot in the brain. Thrombectomy is performed by inserting a catheter (thin needle) into the artery to reach the blood clot and mechanically remove it. With the clot removed, normal blood flow to the brain resumes. Thrombectomy is typically performed at most six hours after a patient shows signs of a stroke.

Hemorrhagic strokes are treated with blood-saving medication and surgery. For a hemorrhagic stroke caused by the rupture of an aneurysm (blood vessel bulges), surgery to stem the bleeding aneurysm and vessel may be used. One surgical technique is stent-assisted coiling, which adds a stent (small wire-meshed tube) into the blood vessel to block the leaking opening of the aneurysm. A non-surgical procedure is endovascular coiling, where a catheter (thin, hollow needle) places a platinum wire coil at the spot of the aneurysm. The coil blocks bleeding and prevents the aneurysm from continuing to leak blood. These procedures are usually combined with blood-thickening medications. Blood transfusions may be administered if substantial blood loss has occurred.

Since stroke patients may have lost some essential functions while the blood flow to their brains was obstructed, both ischemic stroke and hemorrhage stroke patients may receive post-stroke rehabilitation to rebuild their physical and mental abilities. Some restorative treatments include occupational, physical, and speech therapy. Patients may also receive care from neurologists, who can assist patients in recovering certain brain functions and cognitive abilities, and rehabilitation psychologists, who may help patients with their emotional, behavioral, and cognitive recovery. Some stroke patients require lengthy rehabilitation and may never fully regain function, while others may recover more quickly. While the fastest recovery improvements are usually seen in the first three or four months, stroke rehabilitation can last for years.

If someone begins to show signs of stroke, contact emergency services and call 9-1-1 immediately since blood flow must be restored as soon as possible to help avoid significant brain damage. If an ambulance takes the person to the hospital, paramedics can initiate stroke treatment as soon as the patient enters the ambulance, allowing for more prompt medical intervention and care.

This was an annual test/consultation with Dr. Hayes to monitor a condition to see if I would need surgery. Dr. Hayes explained my condition, tests needed, and gave a clear explanation of the test results. The person who did the ultrasound was very kind, and concerned he didn't hurt me during the test.

Dr. Hayes and his staff were extremely knowledgeable and professional about vascular problems that I've been having with both of my legs. I had a vascular procedure done on my left leg recently to help my varicose veins. I was very pleased with the procedure. So far, everything is healing well.

Dr Hayes is a doctor I trust and can communicate very well with. He takes the time we need to discuss whatever questions or concerns I have. I never feel rushed or patronized. He really cares about his patients, which is hard to find these days.

I had not thought about it until now, that I did not receive a follow up call or letter to summarize my ultrasound. The doctor did review It with me at the office visit.
