Reaching deep into the brain to treat strokes [and aneurysms]
Reaching deep into the brain to treat strokes [and aneurysms] [Star Tribune, June 24, 2017] The skinny tools that can reach deep into the brain to treat aneurysms and strokes without cutting the skull have advanced far enough to spur new medical specialties known as endovascular surgery and interventional neuroradiology... Today about 70 percent of brain aneurysms are treated with skinny tubes inserted in blood vessels lower in the body and then advanced through the blood vessels until they reach the brain. Now similar types of tools are being used to reach stroke-causing blood clots as well, but...only about 1 in 10 stroke patients who would benefit from the highly recommended therapy get it. Terri Hopp, 63, of Litchfield, is one of the people who feels she has benefited. Earlier this month, Dr. Josser Delgado repaired Hopp’s non-ruptured aneurysm at Abbott Northwestern by placing four metal coils inside the 5-millimeter balloon of weakened tissue on the left side of Hopp’s internal carotid artery terminus, a major vessel in the brain. Over time, the metal coils will allow Hopp’s body to form scar tissue that seals up the bulging aneurysm, greatly reducing the risk that it will burst and suddenly kill her one day. “I’m back to work and everything’s good,” Hopp said Wednesday. “I’m not nervous and scared that it’s going to rupture any minute.” Read the full article at Star Tribune.com.rthwestern by placing four metal coils inside the 5-millimeter balloon of weakened tissue on the left side of Hopp’s internal carotid artery terminus, a major vessel in the brain.

Inside Your Health Special: Stroke - When Seconds Count
[KSTP, June 29, 2015] Watch Dr. Delgado in this special edition of "Inside Your Health" featuring the Abbott Stroke Team. Fortune and daughter find their way to Faribault man during stroke
[Faribault Daily News, May 20, 2015] While there were no unusual astrological phenomena on March 13, the stars were definitely aligned in the life of a local man who suffered a stroke while driving in town. “He was very lucky,” said Delgado. “For every minute that passes, two million neurons die because they’re not getting enough oxygen. It’s lucky he was recognized as having a stroke and taken to the ER in Faribault.” Read the full story at Faribault Daily News. 
How a Faribault, Minn. man survived a stroke while driving
[KMSP, April 30, 2015] Jerome Nelson, who lives outside Faribault, Minn. has quite a story to tell. Considering how the odds were stack against him, it is amazing he is alive to tell it. The story began on March 13. Fortunately, this Friday the 13th brought him and his family not the luck usually associated with the date, but good luck. “I gotta rest, I get kind of tired, but I'm getting better all the time,” Nelson said looking back on his ordeal. The ordeal in question began with a simple trip to the car dealership. He left, with his wife following him, to drop off a car at a dealership, when he suddenly the entire right side of his body went numb. “My arm wouldn't work, my leg wouldn't work. I couldn't get it off the gas pedal. I just kept speeding up and speeding up,” Nelson said. “Other than that, the rest of the 10 miles into Faribault. I don't remember any of it.” His wife Cindy, who at the time was following him into Faribault, could tell something was wrong. “I'm positive he was going faster than 70, because I was going 70 at one point and I could not keep up with him. He was just gone,” she said. No one knows if the three lights he went through were red or green, but Jerome says he does remember hitting a few curbs and somehow making a few turns before coming to a stop. “I could have very easily gone in a ditch, and killed myself there -- let alone someone else,” Nelson said. When he did finally get the car stopped, his wife was nowhere in sight. It was then, luck (or fate) came into play. His daughter, Shannon Nelson, lives in Faribault, about 10 miles from her parents' home outside of town. It was while she was running an errand to the grocery store she came upon her father's car on the side of the road. “He was slouched over and I could see his lip was going down. I know that's a major sign for a stroke,” Shannon, who has medical training from her job working in a group home, said. Nelson was airlifted to Abbott Northwestern, and within 24 minutes of arriving, doctors had the blood clot in his brain removed. Dr. Josser Delgado, who treated Jerome, says if help hadn't found him so quickly, he wouldn't be doing as well as he is today. Dr. Delgado also credits Shannon's ability to recognize the signs of a stroke – the drooping face, inability to talk, weak arms and legs – with helping avoid something direr from happening. “The moral of the story is when in doubt. It's such a devastating medical condition. And time is so precious, if there are any questions or concerns go to an emergency department right away,” Dr. Delgado said. Nelson can't thank the people who saved his life enough. He also hopes that by telling his story, he can help others. “I don't know how I got there, I don't know who was driving the car for me. But it wasn't me.” It is estimated that someone in the United States has a stroke every 40 seconds. Watch the news video at Fox9.com New technique has stroke patients on the mend
[WCCO-TV, Feb. 9, 2015] Cutting edge technology being used at Abbott Northwestern Hospital could change the treatment for stroke patients. Doctors use a machine with a catheter and suction to remove the stroke-causing blood clot, essentially like a miniature vacuum.. The recovery time can be much quicker than the traditional procedure of using medication to dissolve a clot. Few understand the impact of a fast recovery better than Kyle Smith. Two months ago, Smith was being rushed into Abbott Northwestern. A blood clot in his carotid artery caused a massive stroke, paralyzing the right side of his body and his ability to speak. “I’ll tell you, it’s a life changing experience, for sure,” Smith said. Dr. Yasha Kayan (Kadkhodayan) performed the mechanical thrombectomy. |

Technology provides Cambridge woman with alternative methods for brain aneurysm treatment
[Isanti County News, November 11, 2015] Diane Nelson was treated using both Pipeline and coils simultaneously - a treatment of larger aneurysms which has the highest chance of being successful. “(Pipeline has) given us a very, very valuable tool to treat people with brain aneurysms,” Dr. Delgado said. “(It is a) huge advancement in our field for endovascular treatment of aneurysms. It has allowed us to treat aneurysms that were not treatable before.” Read the full story at IsantiCountyNews.com.

Aneurysm device study looking for volunteers
[KARE-TV, Jan. 13, 2015] Wendy Salter keeps a selfie of sorts on her phone. It’s a picture of blood vessels in her brain and an aneurysm protruding from them. Showing the picture, she laughed, “It looks like a stick person so if you think about it, it’s like your subconscious.” The head of the stick figure, the aneurysm, was found when she had dental problems. She explained, “I had an infection, an abscess, under my tooth and when they did a CT scan to see how deep it was they found it.” Neurointerventionalist Dr. Josser Delgado of Abbott Northwestern Hospital said a majority of aneurysms he has treated have been found when doctors are looking for something else.

Abbott Northwestern Hospital researchers to conduct MRI study of aneurysm-linked strokes
[KMSP Fox 9 News, Nov. 12, 2013] Researchers at Abbott Northwestern Hospital are conducting a first-of-its-kind study in this country in the hopes that understanding a type of stroke caused by aneurysms could yield a life-saving prevention strategy. Every year, 30,000 Americans suffer a ruptured aneurysm, and though 60 percent survive, many are at risk of fatal or debilitating strokes. Now, interventional neuroradiologist Dr. Yasha Kayan (Kadkhodayan) is trying to prevent those strokes from happening. 
Allina surgeons get new treatment approach for brain aneurysms
[Star Tribune, Jan. 30, 2012] As physicians, nurses and technicians looked on, Dr. Josser Delgado gingerly inserted a catheter into an artery in the leg of a 55-year-old woman. To guide them, the neuroradiologists watched their progress on several screens showing multiple images of the blood vessels in her brain. It was her brain — or, more accurately, a large 1-inch cerebral aneurysm — that was their destination. Delgado’s team at Abbott Northwestern is the only group in the Twin Cities area, and one of only two in Minnesota, implanting the Pipeline device. Read the full story at startribune.com. 
HeadachesGood Question: Why Do We Get Headaches?
[WCCO 4 News March 2, 2017] Headaches are not pain in a person’s brain because the brain itself doesn’t have any pain sensors in it. “Headaches are usually related to pain sensors in the lining of the brain or in the blood vessels of the brain,” said Dr. Yasha Kayan, an interventional neuroradiologist with Allina Health.
