How Two Legal Drugs Caused My Hemorrhagic Stroke

Pittsburgh, PA, is the magical land of good health where people embark on a journey just to be here, with Pittsburgh's reputation of new discoveries and treatments. Just today, I heard about a doctor who gave a man an artificial lung machine in a unit no bigger than a BLT sandwich.

Pittsburgh is where I found out stuff I didn't know, like my upcoming surgery on July 14 with the famed Dr. Dane Wukich, foot and ankle expert extraordinaire, to correct my drop foot, (or foot drop), where the tendons and muscles are not working enough to pull the ankle up. I want to run the Marathon--any Marathon--so I have to get my ankle working. (But that's another story for another day).

Today, I learned even more stuff. I took Coumadin, the blood thinner, from the start of my stroke over 5 years ago until now. I had loads of doctors then, and the communication between them was, at best, lousy. So I was on Coumadin until today when the well-known hematologist, Dr. Dhaval R. Mehta, who took lots of tests last month, figured out that I didn't need Coumadin anymore.

"No Coumadin?" I asked.

"No, you're done," the doc replied.

"Do I have to ween off of it?" 

"No, you're done," he said again. "Somewhere down the line, you should have been taken off Coumadin," Dr. Mehta said.

I was satisfied with Dr. Mehta's response but not with the last part. Somebody screwed up. But he had all the test results and I listened intently. But there was still a piece missing: why did I have the stroke? I was the picture of health: low cholesterol, low blood pressure, a non-smoker, no diabetes, a runner. So I put together some of my research as well.

This is my own theory. Avelox, an antibiotic, could result in clots as the side effect of that drug. I was in the hospital two weeks before I had my stroke in 2009 for an ear infection. So the ear doctor in Philadelphia put me on Avelox, and as a result, I got clots in both legs and I went to the ER because of the pain. 

The ER doctor admitted me and I was put on Lovenox, a low-molecular form of Heparin, to break up the clots. (Now here's where the story gets interesting). As a result of being on Heparin, I developed Heparin-induced thrombocytopenia (HIT), a serious side effect that may occur when one is being treated with heparin.

HIT can lead to low blood platelet counts, which I had. My platelet count went down to 18,000 and a normal platelet count is around 237,000 per mcL in men and 266,000 per mcL in women. 

HIT occurs in about 3% of people who are treated with heparin. HIT is more likely to occur with use of higher doses of heparin, but HIT can also be caused by very small heparin doses, including the amount used to flush intravenous catheters. So the very drug that was supposed to help me gave me HIT.

HIT is sometimes referred to as “heparin allergy." However, this is not correct terminology because it is not a true allergy. In most cases, the body makes antibodies to protect us from infections. The immune system in some people, for some reason the docs haven't figured out yet, makes antibodies in response to treatment with heparin. 

After the antibodies bind to the platelets, they are removed together with the platelets from the blood stream, resulting in a low platelet count.  Thus, HIT. And HIT can cause bleeding in the brain. Thus, a hemorrhagic stroke. 

Again, it's my own theory. So no more weekly blood tests, now that my taking Coumadin has ended. No more worrying about Vitamin K and cranberries, the substances that determined, in part, my Partial Thromboplastin Time (PTT) blood result. 

I celebrated by going home and having a turkey sandwich without the leafy greens (Vitamin K). Tomorrow, as the celebration continues, I will have cranberry juice. This weekend, I'm going to have some wine. Alcohol wasn't allowed with Coumadin. 

It took me over 5 years to discover that my taking Coumadin is finally over. I am satisfied with Dr. Mehta's decision. And the mystery of why I got a stroke has ended, to my way of thinking. Two legal drugs.... You never know.

My Upcoming Surgery for Foot Drop, aka My 50/50 Gamble

This may be my last post until my surgery on July 14th. Or maybe not. Anyway, I'll update you as soon as I can on the surgery. As usual, here's some background on the operation.

Ever since the stroke, I developed foot drop (or drop foot--I've heard it both ways), meaning the muscles and tendons that pull the foot and toes up are no longer working substantially. I walk on the side of my foot and the toes are not flat on the ground.


The American Orthopedic Foot and Ankle Society (AOFAS) says, "The surgical procedure for a foot drop is called a tendon transfer. In general, a tendon transfer is a procedure in which a tendon (and attached muscle) that is still working is taken from one part of the foot and moved to another part of the foot to try to replace the muscle function that is missing. The most common tendon transferred is the posterior tibial tendon." 

There's more. A second tendon, the peroneus longus, is severed above the ankle on the outside side of the leg. 


This tendon is then transported to the front of the ankle and the free end "is attached to the posterior tibial tendon and the anterior tibial tendon in a bridle configuration. With this construct, the posterior tibial muscle pulls on all three tendons to pull the foot up. The posterior tibial tendon is routed to the top of the foot as described above," says the AOFAS. Clever, huh!

Here's what it looks like when it's finished:  



Am I scared? Sort of. Anything could happen during surgery: anesthesia going south, infections. But do I have confidence in Dr. Dane K. Wukich? Absolutely!

As his website says, "Dr. Wukich is the chief of the foot and ankle division and associate professor of orthopaedic surgery at the University of Pittsburgh Medical Center. He is recognized nationally and internationally in this field and practices within the UPMC system and the Veterans Administration Medical Center is Pittsburgh. 

"His 80 publications include scientific articles, reviews and book chapters and he has presented over 150 medical lectures during his career. As a board certified orthopaedic surgeon with subspecialty training in foot and ankle surgery, Dr. Wukich is uniquely qualified to treat traumatic, degenerative, congenital and acquired disorders of the lower extremity. His orthopaedic training included comprehensive education in:

Amputations of the Lower Extremity  
Amputation Prevention 
Arthritis 
Biomechanics 
Degenerative Joint Disease 
Diabetes and its Impact on the Foot and Ankle 
Joint Arthroplasty 
Limb Salvage 
Metabolic Bone Disease and its Impact on the
Musculoskeletal System 
Neuromuscular Disorders and Spasticity 
Rehabilitation 
Sports Related Issues and Overuse Disorders 
Trauma"

Dr. Wukich examined my foot and said I am a candidate for this surgery because I have some minimally working muscles in my ankle and foot. If the operation is successful, I won't have to wear the cumbersome brace anymore. The doc said my chances are 50/50. 

How come no one in Philadelphia or South Jersey, where I am from, recommended this surgery? I haven't a clue. But I'm glad I came to Pittsburgh to find this information. 

By the way, Dr. Wukich doesn't know anything about this post. I won't tell him, either. He's a humble man, I think. But people who have drop foot will be educated on what they can do about it. "Options" is my middle name.

So I won't say "goodbye." That word is so final. Rather, I'll say, "See you later."

3 months later:
Surgery is a success! No foot drop and my foot is flat on the floor! I'm wearing the brace for now, but who knows what the future will bring? But I'm staying positive and maybe....
