Robotically assisted bypass surgery reduces complications after surgery and cuts recovery

28.10.2014

Less invasive type of heart surgery using robotic precision is safe, quick and clean

Robotically assisted coronary artery bypass grafting (CABG) surgery is a rapidly evolving technology that shortens hospital stays and reduces the need for blood products, while decreasing recovery times, making the procedure safer and less risky, says a study presented at the Canadian Cardiovascular Congress.

"Robotically assisted CABG is a safe and feasible alternative approach to standard bypass surgery in properly selected patients. It is a less traumatic and less invasive approach than regular CABG," says cardiac surgeon and researcher Dr. Richard Cook of the University of British Columbia. "It may reduce complications following surgery, and in the Canadian experience, has been associated with an extremely low mortality rate."

For CABG, or bypass surgery, a surgeon uses a section of vein, usually from the patient's leg, or an artery from inside the patient's chest, to create a new route for oxygen-rich blood to reach the heart. It is performed to improve blood flow to the heart muscle caused by the build up of plaque in the coronary arteries (atherosclerosis).

The robot offers several technical advantages to surgeons including a magnified 3D view of the patient's heart, as well as the elimination of any kind of tremor, which makes for precise incisions.

For this study 300 patients (men and women 60 years or older) underwent robotically assisted CABG at three hospital sites. In addition to the Vancouver General Hospital, the study was undertaken at the London Health Sciences Centre, led by Drs. Bob Kiaii and Michael Chu, and at Montreal's Sacred Heart Hospital, led by Dr. Hugues Jeanmart.

There were no deaths in this group of patients, with only one patient developing a deep wound infection after the procedure.

The doctors performed the surgery using the da Vinci Surgical System. It consists of a "surgeon console" where the surgeon views a high definition 3D image inside the patient's body. When the surgeon's fingers move the master controls, the system's "patient-side cart" springs into action with three or four robotic arms mimicking the surgeon's hand, wrist and finger movements with surgical instruments.

With traditional CABG the average hospital stay is five to six days. With the robotically assisted surgery, that was cut to an average of four days in the group of patients having surgery at London Health Sciences Centre; the hospital with the greatest experience with robotically-assisted cardiac surgery in Canada.

There was also less blood loss, which translated into a lower need for blood products. The more precise incisions also mean less cosmetic scarring.

Patients from the study reported being back to near normal levels of activity within a couple of weeks. With standard CABG, patients are asked to avoid driving or lifting any weights over 10 pounds for six weeks.

"Each year nearly 25,000 bypass surgeries are performed in Canada,; it is the most common form of surgery for people with heart disease," says Heart and Stroke Foundation spokesperson Dr. Beth Abramson, author of Heart Health for Canadians. "Surgery saves lives and helps improve quality of life. The safer we can make the surgery, the more lives we can save."

She adds that bypass surgery doesn't cure the underlying heart disease. "Health behaviour changes and medications as prescribed by your healthcare providers are critical to preventing further damage."

Currently, 17 centres across Canada use this robotic technology for surgery. However, they are used primarily in the fields of urology and gynecology. Dr. Cook and his colleagues hope findings from this study will increase the use robotically assisted heart surgery.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
