The good news is that the hospital is being very thorough in their testing before taking Dennis to surgery. The bad news is that all the testing, and the resulting delays, are making Dennis a little testy.
They've done an ultrasound test to check the circulation in his feet and lower legs. They've done a CT scan. And they've done another ultrasound test to map the arteries in the left leg, which is the one that has the foot with the dead toes.
He was supposed to have had an angiogram today, inserting dye into the artery or arteries in that left leg, further checking the circulation. At the same time, they were going to check the veins in the right leg to see if any of those could be used to improve the circulation in the left leg. Unfortunately, those tests have been delayed until tomorrow.
So, at this point, it's looking like it might be next week before the actual surgery can happen.
