An aneurysm is an outward bulging, likened to a bubble or balloon, caused by a localized, abnormal, weak spot on a blood vessel wall. Aneurysms may be a result of a hereditary condition or an acquired disease. Aneurysms can also be a nidus for clot formation (thrombosis) and embolization. The word is from Greek: ἀνεύρυσμα, aneurysma, "dilation", from ἀνευρύνειν, aneurynein, "to dilate". As an aneurysm increases in size, the risk of rupture increases, leading to uncontrolled bleeding. Although they may occur in any blood vessel, particularly lethal examples include aneurysms of the Circle of Willis in the brain, aortic aneurysms affecting the thoracic aorta, and abdominal aortic aneurysms. Aneurysms can arise in the heart itself following a heart attack, including both ventricular and atrial septal aneurysms. There are congenital atrial septal aneurysms, a rare heart defect.
Vascular surgery is a surgical subspecialty in which diseases of the vascular system, or arteries, veins and lymphatic circulation, are managed by medical therapy, minimally-invasive catheter procedures, and surgical reconstruction. The specialty evolved from general and cardiac surgery, and includes treatment of the body's other major and essential veins and arteries. Open surgery techniques, as well as endovascular techniques are used to treat vascular diseases. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system excluding the coronaries and intracranial vasculature.
An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size. They usually cause no symptoms except when ruptured. Occasionally, there may be abdominal, back, or leg pain.
Abdominal aortic aneurysm is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. They usually cause no symptoms, except during rupture. Occasionally, abdominal, back, or leg pain may occur. Large aneurysms can sometimes be felt by pushing on the abdomen. Rupture may result in pain in the abdomen or back, low blood pressure, or loss of consciousness, and often results in death.
A thoracic aortic aneurysm is an aortic aneurysm that presents primarily in the thorax.
The coeliacartery, also known as the coeliac trunk, or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in humans, it is one of three anterior/ midline branches of the abdominal aorta.
Phlegmasia cerulea dolens (PCD) [literally: painful blue inflammation; not to be confused with preceding phlegmasia alba dolens] is an uncommon severe form of lower extremity deep venous thrombosis (DVT) that obstructs blood outflow from a vein. Upper extremity PCD is less common, occurring in under 10% of all cases. PCD results from extensive thrombotic occlusion of extremity vein(s), most commonly an "iliofemoral" DVT of the iliac vein and/or common femoral vein. It is a medical emergency requiring immediate evaluation and treatment.
Endovascular aneurysm repair (EVAR), is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair." The procedure involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. In 2003, EVAR surpassed open aortic surgery as the most common technique for repair of AAA, and in 2010, EVAR accounted for 78% of all intact AAA repair in the United States.
Michael L. Marin is an American vascular surgeon. Together with Drs. Frank Veith, Juan C. Parodi and Claudio J. Schonholz, he was the first in the United States to perform minimally invasive aortic aneurysm surgery. In 2004, he was the first doctor to implant an intravascular telemetric monitor -- a device that alerts to physicians any leakage in aortic stent-grafts.
Peter Lin is an American vascular surgeon, medical researcher, specializing in minimally invasive endovascular treatment of vascular disease. He has published extensively in the area of vascular surgery and endovascular surgery.
Kenneth Ouriel is a vascular surgeon and medical researcher. He has published in scientific and medical journals. He treated former presidential candidate Bob Dole for an abdominal aortic aneurysm in 2001. In the middle 2000s, Ouriel went to Dubai as CEO to help build a world-class hospital; he treated several Middle Eastern rulers in addition to his administrative duties. In 2009, he was senior vice president and chief of international operations at New York-Presbyterian Hospital. He has been described as one of America's top vascular surgeons.
A hybrid cardiac surgical procedure in a narrow sense is defined as a procedure that combines a conventional surgical part with an interventional part, using some sort of catheter-based procedure guided by fluoroscopy imaging in a hybrid OR without interruption. A wider definition includes a clinically connected succession of a catheter intervention and a surgical procedure with a time gap.
Vascular and Endovascular Surgery is a monthly peer-reviewed medical journal that covers the field of vascular surgery. It was established in 1967 and is published by Sage Publications. The editor-in-chief is Thomas Maldonado.
Perspectives in Vascular Surgery and Endovascular Therapy was a quarterly peer-reviewed medical journal that covered research in the field of angiology. Its editor-in-chief was Peter Gloviczki. It was established in 1988 and was published by Sage Publications until December 2013.
Perforator veins are so called because they perforate the deep fascia of muscles, to connect the superficial veins to the deep veins where they drain.
Rajiv Parakh is the chairman at the Division of Peripheral Vascular and Endovascular Sciences at Medanta, Gurgaon, India. In 1986 he completed his vascular surgery training and acquired a fellowship from the Royal College of Surgeons in the United Kingdom. He returned to India where, in 1990, he established one of the country's first independent departments of vascular surgery at a city hospital.
Juan Carlos Parodi is an Argentinian vascular surgeon who introduced the minimally invasive endovascular aneurysm repair (EVAR) to the world and performed the first successful endovascular repair of an abdominal aortic aneurysm on 7 September 1990 in Buenos Aires. In 1992 he was the first in the United States to perform minimally invasive aortic aneurysm surgery together with Drs. Frank Veith, Michael L. Marin and Claudio J. Schonholz. He continues to develop new techniques, including seat belt and air bag technique for cerebral protection during carotid stenting. He is recognized as a renowned pioneer in the specialty of endovascular repairs of the aorta.
Gurukumar Balachandra Parulkar is an Indian cardiothoracic surgeon and a professor emeritus at King Edward Memorial Hospital and Seth Gordhandas Sunderdas Medical College. He also served as the president of the Association of Surgeons of India in 1984.
Thomas J. Oxley is the chief executive officer of Synchron and neurointerventionist at Mount Sinai Hospital in New York City. Trained as a vascular and interventional neurologist, he established the Vascular Bionics laboratory at the University of Melbourne and is currently co-head of this lab. Oxley is best known for founding Synchron, a company building next-generation brain computer interface solutions that has recently announced the first clinical data on a novel stent electrode (Stentrode) neural interface that is inserted through blood vessels. The company was initiated sometime after his cold-call to DARPA for funding, and has received substantial funding from the U.S. Defense Advanced Research Projects Agency (DARPA) and the Australian government to research this minimally-invasive neural interface technology.
Gustavo S. Oderich MD is a vascular and endovascular surgeon and serves as a professor and chief of vascular and endovascular surgery, and is the director of the Advanced Endovascular Aortic Program at McGovern Medical School at The University of Texas Health Science Center at Houston and Memorial Hermann Health System. He previously served as chair of vascular and endovascular division at the Mayo Clinic in Rochester, Minnesota. Oderich is notable and recognized for his work in minimally invasive endovascular surgery and research in fenestrated and branched stent-graft technology to treat complex aortic aneurysms and dissections.
