What is the definition or description of: thrombectomy?

Removal of bloodclot: Thrombectomy is removal of a blood clot. It can be performed with a catheter using either an open or closed technique. The open technique uses an incision to expose a blood vessel, then a catheter with a collapsed balloon at its end, is passed into the vessel, past the clot. The balloon is inflated, pulled back, and the clot removed. Sometimes this can be done thru the skin by closed technic. ...Read more

Why would clots be forming after a thrombectomy?

Same as original.: For the same reason they formed prior to removal of the clot. A thrombectomy is just a removal of clot. If the underlying disorder that caused the clot is not treated, it is likely the clot will recur. ...Read more

What causes clots to keep forming after a thrombectomy?

What causes clots to keep forming after a thrombectomy?

Some Possibilities: Some possible causes are: unrecognized and thus untreated arterial blockage that results in: *poor arterial inflow into artery that is thrombosed *poor runoff from artery that is thrombosed. *poor flow through the bypass (if patient has a bypass) hyper-coagulable state allergy to the blood thinner heparin...This can cause a syndrome called hit that results in thrombosis. ...Read more

Please explain why would clots keep forming after a thrombectomy?

Where are clots?: Either 1) disease in the blood vessel, 2) a clotting disorder or 3) clot in the heart or other location which is traveling and lodging at site of thrombectomy (embolus). ...Read more

I : I believe that you also asked this question elsewhere, so escuse me if the first part of my answer is a repeat. The ankle-brachial index (abi) is a screening test done with blood pressure cuffs and an ultrasound probe. An mra, in contrast, uses magnetic fields and injected dye to directly visualize the anatomy of the blood vessels. Therefore, while an mra might show a blocked dorsalis pedis artery, it would not be reported as showing an abi of zero. The abi tests blood pressure in the dorsalis pedis and the posterior tibial arteries and compares those measurements to blood pressures in the arms. If the pressures in the feet are significantly lower than those in the arms, and/or the patient has clinical signs of decreased blood flow to the feet, then one may decide to intervene. It sounds to me like you had no pulse in your dorsais pedis artery before your surgery, regardless of what your abi might have been. This could have happened because of chronic blockage or because of new clot that might have formed a) because of decreased flow in an already-diseased dorsalis pedis or b) because of clot that came from abnormal vessels upstream. You had an aortic bypass, so there certainly was disease upstream. It sounds to me like your surgery was a difficult one. However, it's hard to know whether your doctor was fixing problems that were caused by the surgery or whether you just had a lot of disease to begin with and he or she was trying to fix a of of problems at the same time. Unfortunately, a lot of people with bad arterial disease wind up in a wheelchair or with amputations despite the best efforts of good doctors. Still, if you think your doctor made a mistake, you should certainly talk it over with him or her and consider seeing another doctor for a second opinion. ...Read more

What are thrombectomies and embolectomies?

What are thrombectomies and embolectomies?

Blood clot removal: Emboli and thrombi are blood clots, an embolus is one that has traveled and lodged an a vessel and a thrombus is a blood clot that has formed in a vessel. Removal of the blood clot is performed, usually surgically, to restore blood flow. In the case of a thrombectomy, in addition to removing the clot, one needs to treat the cause of the vessel thrombosis...by removing blockage that caused thrombosis ...Read more

Am I dying?

Am I dying?

We all are: A 3-word question with no details... well, life is short on Earth, regardless of whether a person lives 3 days, 3000 days, or 30,000 days. It is not length of one's life that matters, but the quality of the life lived. The goal is not to live a long life, but to live a good life. Even if a person makes it all the way to age 82, that's only 30,000 days. ...Read more
