A pulmonary thrombectomy is an emergency surgical procedure used to remove blood clots from the pulmonary arteries. Mechanical thrombectomies can be surgical (surgical thrombectomy) or percutaneous (percutaneous thrombectomy). [1] Surgical thrombectomies were once popular but were abandoned because of poor long-term outcomes.
Furthermore, movement from the heart makes delicate work on the closely attached pulmonary arteries complex. Hypothermia is necessary as the embolus is very delicate and the risk of disruption is high, in order to appropriately visualize the clot and remove it a bloodless field is required. Clot visualization is achieved through dissection of ...
Surgical or catheter embolectomy is a procedure performed in patients with pulmonary embolism, which is a blockage of an artery in the lung caused by a blood clot. This procedure is typically used for patients who are in a critical condition, such as those who are experiencing persisting shock despite receiving supportive care, and who have an ...
A system of coaxial catheters is pushed inside the arterial circulation, usually through a percutaneous access to the right femoral artery. A microcatheter is finally positioned beyond the occluded segment and a stent-retriever is deployed to catch the thrombus; finally, the stent is pulled out from the artery, usually under continuous ...
An embolized fragment of an atrial myxoma in the iliac bifurcation. Although a myxoma is not malignant with risk of metastasis, [3] complications are common. Untreated, a myxoma can lead to an embolism (tumor cells breaking off and traveling with the bloodstream). Myxoma fragments can move to the brain, eye, or limbs. [citation needed]
The right atrial appendage (lat: auricula atrii dextra) is located at the front upper surface of the right atrium. Looking from the front, the right atrial appendage appears wedge-shaped or triangular. Its base surrounds the superior vena cava. [6] The right atrial appendage is a pouch-like extension of the right atrium and is covered by a ...
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
