Alexandra J. Golby, MD, Director, Image-guided Neurosurgery at Brigham and Women’s Hospital, discusses technological advancements to improve the precision of surgery to remove brain tumors.
It’s estimated that each year nearly 80,000 people are diagnosed with primary brain tumors and 100,000 with metastatic brain tumors. Nearly everybody is at risk for developing a brain tumor. Brain tumors can affect people from childhood to the last years of their lives. Men are slightly more affected than women and the causes of most brain tumors are not known.
There are a number of unique challenges in treating brain tumors. One challenge is that primary tumors can have indistinct margins that are difficult to see. Another challenge is that the tissue around a brain tumor is uniquely important and may impact things like language, visual and motor function.
The AMIGO Suite, opened in 2011 at Brigham and Women’s Hospital, is the Advanced Multimodality Image Guided Operating Suite. It's an NIH-funded national center which was developed with the goal of translating technological advances into improvements in surgical and interventional care for patients. In the AMIGO Suite, there is an intraoperative MRI scanner which can be brought in and out of the operating room during surgery to help surgeons visualize a patient’s tumor better.
Image-guided surgery uses the information obtained from advanced imaging and translates that into the planning and execution of surgery by acquiring high resolution and specialty structural images of the brain and also functional images of the brain. These images can be registered to one another and then to the patient's head during surgery. This allows surgeons to pinpoint the location of the tumor as well as the areas that we would like to preserve, areas that serve critical brain functions are located.
One of the big challenges, even with image-guided surgery, is that as we perform the surgery, the configuration of the brain is changing, and we call that brain shift. And it's due to changes in the brain itself and also as we remove tissue, things are constantly shifting and moving. When we're talking about doing brain tumor surgery, a few millimeters of movement can be a big difference. How to measure and track brain shift is an important area of research and a number of technologies are being studied to understand how to measure brain shift during surgery.
The development of various intraoperative imaging technologies allows surgeons to provide the most accurate surgical treatment for each individual patient.

This video, created by Nucleus Medical Media, shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.
This is similar to the procedure performed on former president Bill Clinton and former California governor Arnold Schwarzenegger.

CORRECTION: After review of this video, it is clear that this video is of a baby who is near full term (40 weeks) based on the size. Late trimester "abortions" are defined only to viability of a baby (24 weeks) A 24 week baby is much smaller than this baby shown and by definition this is not a late "abortion" procedure. The proper labeling of this video should be management of a deceased breech baby with "head entrapment" as this was almost certainly a naturally occuring delivery and an OB nightmare (Reviewed by Dr. Frederick Bright)
Thyroid nodules increase with age and are present in almost 10% of the adult population. Autopsy studies reveal the presence of thyroid nodules in 50% of the population, so they are fairly common. 95% of solitary thyroid nodules are benign, and therefore, only 5% of thyroid nodules are malignant.
To use the diaphragm, first cover the inside of it with spermicide. Then insert it into your vagina so that it covers your cervix. You can insert the diaphragm up to 6 hours before sex. You should leave it in for at least 6 hours after the last time you have sex.
Your baby's sex is set at conception. At around 7 weeks, your baby's internal sex organs – such as ovaries and testes – begin to form in the abdomen. Male and female sex organs and genitalia look the same at this stage because they're derived from the same structures. At around 9 weeks, boys and girls begin to develop differently. In girls, a tiny bud emerges between the tissue of the legs. This bud will become the clitoris. The membrane that forms a groove below the bud separates to become the labia minora and the vaginal opening. By 22 weeks, the ovaries are completely formed and move from the abdomen to the pelvis. They already contain a lifetime supply of 6 million eggs. In boys, the bud develops into the penis and starts to elongate at around 12 weeks. The outer membrane grows into the scrotal sac that will later house the testicles. By 22 weeks, the testes have formed in the abdomen. They already contain immature sperm. Soon they'll begin their descent to the scrotum, but it's a long journey. They'll reach their destination late in pregnancy, or for some boys, after birth. If you're eager to find out whether you're having a girl or a boy, you'll have to wait until you're at least 17 weeks pregnant. That's when the genitals have developed enough to be seen on an ultrasound.
This video provides a demonstration of how to assess for transillumination when assessing scrotal swelling.
