Pulmonary Artery

This video shows management of rupture of the posterior capsule post blunt trauma in a child aged 8. Pre-operative suspicion of PCR was strong because of a flat anterior. So we were careful in our approach from the very beginning. CCC was performed and then dry aspiration of lens matter initiated. Sice vitreous showed, so anterior vitrectomy was done along with systematic removal of the lens matter. An acrysof multi-component lens was implanted into the sulcus and optic captured into the CCC.Outcome was very good.

Laparoscopic Tubal Reversal of fallopian tubes after ligation

With an Ophthalmoscope, light is shone into the eye and the retina and the optic nerve is examined. This is called as Examination of the Fundus. This is what the eye-doctor sees when he peeps into your eye! Through the transparent cornea, into the dark interior. The Fundus Exam When he looks into the eye with the Ophthalmoscope, he sees a orange glowing interior. That is the retina. The retina is actually transparent. It appears bright because of blood vessels in the choroid layer below. It is like looking at your ear against the bright sunlight. The yellow circle is the Optic Nerve, the cable of vision! A red, shiny dot attracts attention. That is the macula. If indicated, the exam of periphery of the retina is done with an Indirect ophthalmoscope. The ophthalmologist wears this instrument on the head and focuses the light into the eye with a lens held in his hand. This is usually done in a dark room.

Arthrocentesis of the Knee

On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com

The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.

Watch as Dr. Benjamin Carson performs risky brain surgery on young Payton to remove a brain tumor. Dr. Carson, director of pediatric neurosurgery, is just one of the many reasons why Johns Hopkins Children's Center was recently ranked #1 in neurology and neurosurgery in America's Best Children's Hospitals 2008

I call this technique deep rendering. I basically stacked graphical cross-sections (in this case, MRI rendering data), using proper increments and clip through them with the camera. This way I am able to explore all internal components in full 3D real-time.

I actually was able to figure out how to colorize different organs to help distinguish them apart from each other but couldn't get the shader to render real-time in Maya.

Biliary and Pancreatic Sphincterotomies for Sphincter of Oddi Dysfunction

This 43 year old woman has severe recurrent RUQ pain post cholecystectomy. Liver and pancreatic chemistries and duct size are normal, but pancreatic manometry is abnormal. The plan is to perform dual biliary and pancreatic sphincterotomy. The pancreatic duct is cannulated with a 3.9 French tip tr...iple lumen papillotome loaded with a 0.025 inch Jagwire. Contrast is injected to outline the course of the duct. The wire is passed to the tail. Notice the knuckling of the wire into the tail. This provides a safety loop, but is only safe in a small duct with use of a smaller caliber wire. Then with the wire securely in PD, papillotome is used to cannulate the bile duct. Placement of the wire in PD guarantees access for pancreatic stent placement, which is mandatory in these patients to reduce risk, it also facilitates difficult biliary cannulation. Here is the fluoroscopic view as the papillotome is passed deep into bile duct. This shows wires in the CBD and PD. Now a biliary sphincterotomy is performed, with the pancreatic guidewire in place beside the papillotome. The scope is pushed into a longer position to orient up the middle of the papilla. The sphincterotomy is done in very careful stepwise fashion to avoid perforation. Now the biliary wire is removed and the papillotome passed over the pancreatic wire for pancreatic sphincterotomy. The incision is aimed back up towards the biliary sphincterotomy to ensure the septum only is cut. Note the large pancreatic orifice. Last, a 4 French 9cm unflanged soft material pancreatic stent is placed. We always use single pigtail design to avoid inward migration of the stent. The long unflanged design allows spontaneous passage within a few weeks.
