Cardiovascular and Thoracic Surgery Practice by Dr. Michio Kajitani.:  Yes, He is back in Little Rock.  He is an active staff at Arkansas Heart Hospital, and a consulting staff at Baptist Medical Center, and St. Vincent Infirmary.  He is certified in American Board of Thoracic Surgery and American Board of Surgery, and actively attends National and Internaitonal meetings to keep updated with the latest knowledge and technology.  He moved to San Diego in May 2009 due to family situation, but he is back again to Little Rock joining Little Rock Cardiology Clinic as of January 2011.

Dr. Michio Kajitani is a board certified cardiovascular and thoracic surgeon graduated from University of Arkansas for Medical Sciences fellowship program.  He had medical education and cardiothoracic surgery training in Japan, completed additional fellowship in cardiopulmonary transplant / pediatric cardiac surgery at Mayo Clinic (Rochester, Minnesota), adult cardiac surgery at Dr. Albert Starr's academic institute (Portland, Oregon).  He also has extensive research experience in cardiac transplant, artificial heart valves, application of Laser and biomaterials in surgery.  He performs coronary artery bypass grafting (on and off cardiopulmonary by-pass), valve repair/ replacement, major and peripheral vascular surgery, carotid endarterectomy, repair of congenital cardiac defects, lung resection, mediastinal surgery, and treatment of varicose vein using radiofrequency vein closure device.  He is particularly interested in developement of new technologies for minimally invasive surgical treatment to improve surgical outcomes.


If you experience discomfort, swelling and varicose veins in your legs, you may be suffering from superficial venous reflux disease. Approximately 25 million people in the United States suffer from this condition. Traditionally patients diagnosed with venous reflux would undergo vein stripping surgery. Now, patients can be treated with the Closure procedure -- a minimally invasive alternative to painful vein stripping surgery.Venous reflux or venous insufficiency develops when the valves that usually keep blood flowing out of your legs become damaged or diseased.

The main treatment alternative is to re-route blood flow through healthy veins. Traditionally, this has been done by surgically removing (stripping) the troublesome vein from your leg. Closure provides a less-invasive alternative to vein stripping by closing the diseased vein instead.


Experience the Closure Procedure

The Closure procedure is performed on an outpatient basis using local anesthesia in which the physician numbs the leg before treatment.  The procedure consists of four principal steps.

Map the Saphenous Vein. A typical procedure begins with noninvasive ultrasound imaging of the diseased vein to trace its location. This allows the physician to determine the site where the Closure catheter will be inserted and to mark the desired position of the catheter tip to begin treatment.

Insert the Closure Catheter. After the physician accesses the saphenous vein, the Closure catheter is inserted into the vein and advanced to the uppermost segment of the vein. The physician then typically injects a volume of dilute anesthetic fluid into the area surrounding the vein. This numbs the leg, helps squeeze blood out of the vein and provides a fluid layer outside the vein to protect surrounding tissue from heat once the catheter starts delivering RF energy. Saline is then slowly infused into the vein from the tip of the catheter to further create a near-bloodless field inside the vein, allowing the catheter to preferentially heat the vein wall, rather than the blood.

Deliver RF Energy and Withdraw Catheter. Noninvasive ultrasound is used to confirm the catheter tip position and the physician then activates the RF generator, causing the electrodes at the tip of the catheter to heat the vein wall to a target temperature of typically 85 degrees Centigrade or 185 degrees Fahrenheit. As the vein wall is heated, the vein shrinks and the catheter is gradually withdrawn. During catheter pullback, which typically occurs over 15 to 18 minutes, the RF generator regularly adjusts the power level to maintain target temperature to effectively shrink collagen in the vein wall and close the vein over an extended length.

Confirm Closing of Vein. After treatment, ultrasound imaging is used to confirm closing of the vein. If a portion of the vein is not closed, the catheter can be reinserted and energy reapplied. After the procedure, the narrowed vein gradually becomes fibrous, sealing the interior of the vein walls and naturally redirecting blood flow to healthy veins. Experienced physicians often complete the procedure in 45 to 60 minutes.

98% of patients who have undergone the Closure procedure are willing to recommend it to a friend or family member
