Peripheral Vascular Disease
Peripheral vascular disease (PVD), also known as peripheral artery disease (PAD), is caused by the obstruction of large arteries in the arms and legs. PVD can result from atherosclerosis which is an inflammatory processes leading to stenosis (narrowing) of blood vessels. It causes chronic ischemia (lack of blood supply); most often in the legs. When symptoms can no longer be sufficiently controlled with medication, stenosis may be treated with an intervention. Methodist Cardiovascular Surgery Associates offers many interventional options including catheter-based removal of plaque (percutaneous transluminal angioplasty or PTA); surgical removal of plaque (endarterectomy); or for blockages that cannot be effectively removed, a bypass graft may be used to restore blood flow.
Carotid Artery Disease
Carotid Artery Disease is a common, treatable narrowing of the major arteries in the neck supplying blood to the brain. Reduced carotid blood flow may lead to stroke. The latest non-invasive Doppler ultrasound tests are used to detect and measure the degree of stenosis (narrowing) enabling Methodist Cardiovascular Surgery Associates physicians to determine the best treatment option. Non-invasive ultrasound testing can monitor the progression of the narrowing and indicate when an intervention is required. Patients who traditionally may have been candidates for open surgery, now also benefit from catheter-based endovascular solutions such as angioplasty, carotid endarterectomy, and the placement of stents to sustain improved blood flow.
Aneurysms (bulging) can occur in the aorta and in distal arteries. The latest diagnostic capabilities are available at Methodist for detecting and imaging life-threatening aneurysms, a condition that may be asymptomatic. Physicians at Methodist Cardiovascular Surgery Associates treat aneurysms with a coordinated, patient-centered set of procedural tools including catheter-based, minimally invasive, and open vascular surgery procedures using the latest stent graft technology. Methodist Cardiovascular Surgery Associates physicians are leaders in researching and developing new aortic surgical techniques including aortic de-branching and hybrid surgical repairs for repairing longer sections of aorta. For patients experiencing aortic dissections, the Acute Aortic Treatment Center is a multidisciplinary approach to providing immediate diagnosis and potentially life-saving treatment.
Limb Preservation Program
Limb preservation surgery, also called limb-sparing surgery, is an alternative to amputation for patients with cancer, degenerative bone and joint conditions, severe circulation problems often resulting from diabetes, or serious wounds. Vascular surgeons work closely with orthopedic and plastic surgeons, and many other disciplines with the goal of preserving the appearance and, to the extent possible, the function in the affected limb. These procedures may involve the transplant of bone and tissues to the affected limb, including the revascularization of the affected tissues (restoring blood flow). Methodist Cardiovascular Surgery Associates physicians use a broad range of imaging technologies including CT and MRI to evaluate and plan limb preservation procedures, providing the opportunity for improved surgical outcomes.
Arteriovenous malformation (AVM) is a congenital condition (genetic abnormality); resulting in abnormal connections between veins and arteries at various locations within the circulatory system. While many people with AVM are asymptomatic, some experience muscle weakness or dizziness and AVM increases the risk for stroke. Treatment alternatives include catheter-based procedures for cutting off abnormal circulatory paths; and surgery for removing the abnormal pathways.
Renal/Mesenteric Occlusive Disease
Renal or mesenteric artery occlusive disease (stenosis or plaque buildup) results in compromised blood flow to the kidneys and intestines and may require a renal/mesenteric revascularization procedure to restore adequate blood flow. The intervention may be a catheter-based angioplasty procedure which may include the placement of a stent; or an open surgical procedure to either repair the blockage or create a bypass.
