Endarterectomy – also known as thrombendarterectomy (TEA) – is a surgical procedure used in vascular surgery. It involves removing atherosclerotic deposits from a narrowed blood vessel. The affected narrowed vessel is opened, cleared of deposits and then reconstructed. Endarterectomy improves blood flow and allows for the targeted treatment of circulatory disorders, such as peripheral arterial disease (PAD).
The method is particularly suitable for vessels that are locally narrowed or blocked. This frequently affects the femoral artery (femoral TEA), the carotid artery (carotid TEA) or vessels in the extremities. If necessary, a patient’s own vein or a synthetic graft is used as an interposition graft.
Surgical treatment of an arterial narrowing in the leg arteries – a typical scenario for endarterectomy (TEA).
Endarterectomy is performed when an arterial circulatory disorder is caused by a significantly narrowed or occluded artery. Typical indications:
- Peripheral arterial occlusive disease (PAOD)
- Intermittent claudication with a painfully limited walking distance
- Occlusion or narrowing of the carotid artery for stroke prevention
- Arterial narrowing in the extremities
- Severe plaque build-up in the femoral artery
- Occlusions that do not improve sufficiently with walking training, medication or minimally invasive procedures
Endarterectomy may also be necessary in cases of diabetic circulatory disorders to prevent amputations. The procedure is particularly beneficial when a narrowing is clearly defined and easily accessible surgically.
The operation is usually performed under regional anesthesia or general anesthesia. The blood vessel is surgically exposed and opened. The vascular surgeon then removes the atherosclerotic deposits using special metal instruments such as a dissector or ring stripper. The vessel is debrided so that the inner vessel wall is cleared and blood flow can proceed unimpeded.
If necessary, the vessel is widened using a patch made from the patient’s own vein or synthetic material, or bypassed using a graft. In some cases, a stent is also inserted or the vessel is dilated using a balloon.
Endarterectomy is one of the classic procedures in vascular surgery and is a key treatment method in the field.
Like any surgical procedure, endarterectomy also carries potential risks:
- Post-operative bleeding or bruising
- Infections
- Formation of blood clots
- Complications due to narrowing or restenosis
- Injury to the vessel wall or neighboring structures
- Rare risks: stroke (in procedures on the carotid artery), vascular occlusion or amputation
Choosing an experienced vascular center significantly reduces the risk.
Endarterectomy yields very good results in cases of locally confined vascular narrowing. It improves blood flow, alleviates symptoms and significantly increases walking distance. In cases of PAD, the progression of the disease can be slowed, particularly if patients consistently manage risk factors such as smoking, high blood pressure or diabetes mellitus.
Regular check-ups at the clinic and supplementary walking training improve long-term outcomes. The prognosis is particularly good if the narrowing can be completely removed and the treatment is combined with statins and other measures.
Depending on the severity and location, the following alternatives may be considered:
- Minimally invasive balloon dilation (balloon expanded)
- Vascular support via stent (stent inserted)
- Bypass to bypass long narrowings
- Interventional procedures for narrowed blood vessels
- Drug therapy (e.g. statins)
- Structured walking training to improve walking distance
Each treatment option is assessed on an individual basis, depending on the condition of the blood vessels and the patient’s general state of health.
Additional treatment options include:
- Modern interventional techniques
- Combined procedures
- Treatment for diabetic foot problems
- Rehabilitation with walking training
- Treatment at the Vascular Center in Bremen or specialist clinics
Endarterectomy is part of a comprehensive treatment plan designed to stabilize conditions such as atherosclerosis, circulatory disorders or narrowing of the arteries in the long term.
Endarterectomy is an effective surgical procedure for treating arterial circulatory disorders. It enables the removal of deposits, improves blood flow and can prevent serious complications such as amputations or strokes. In experienced centers, the procedure has a high success rate and represents an important treatment option for PAD and other vascular diseases.
What is endarterectomy and how is it performed?
Endarterectomy is a surgical procedure in which deposits or calcified sections of the artery are removed to keep the affected blood vessel open. The narrowed vessel is opened, the tissue is scraped out using special instruments, and blood flow is improved. The method is one of the classic procedures in the vascular lexicon from A to Z and is used primarily for PAD, also known as intermittent claudication.
When is endarterectomy more appropriate than a bypass?
Endarterectomy is the preferred option when the narrowing is clearly defined and the artery is not extensively blocked or severely calcified. If a longer segment of the vessel is affected, a bypass may be more appropriate – either using a vein from the patient’s own body or a synthetic graft. The specialist decides which option is suitable based on imaging and the condition of the vessels.
What are the risks associated with endarterectomy?
As with any vascular surgery, complications are possible. These include blood clots, post-operative bleeding, infections or restenosis. If too much of the artery is removed or the tissue is severely damaged, an additional patch or bypass may be required. Disturbances to blood flow in the surrounding blood vessels are also possible, but occur rarely.
Does endarterectomy help with peripheral arterial disease (PAD)?
Yes, endarterectomy is an established procedure for treating peripheral arterial disease. Removing the deposits improves blood flow, which can increase walking distance and reduce pain. In addition, specialists recommend walking exercises, statins and the elimination of risk factors such as smoking or high blood pressure.
What happens if the artery is severely calcified or the vessel is too narrow?
If the narrowed vessel is severely calcified or cannot be completely cleared, a stent may also be inserted to keep the vessel open. Alternatively, the affected section can be bypassed. The decision depends on how much of the artery needs to be removed and how stable the vessel wall is after the procedure.
How long do the results of an endarterectomy last?
The duration depends on the general condition of the blood vessels, risk factors and aftercare. Many patients benefit in the long term if they reduce risk factors, take their medication and attend regular check-ups. Consistent walking exercise also supports long-term success.
