Laser Angioplasty
Laser angioplasty, also called excimer laser atherectomy or CLiRPATH, is a catheter procedure using pulsating laser beams to vaporize arterial plaque instead of a balloon; niche use remains after early trials showed no restenosis benefit.
Mechanical thrombectomy for stroke
Mechanical thrombectomy for stroke is a catheter-based endovascular procedure that removes a clot from a large cerebral artery, the standard of care for large-vessel occlusion stroke.
Mechanical Thrombolysis
Mechanical thrombolysis, also called mechanical thrombectomy, removes blood clots physically via catheter devices rather than drugs. Key devices: Merci Retriever, Penumbra System, stent retrievers, aspiration catheters; standard of care for large vessel occlusion stroke.
Orbital atherectomy
Orbital atherectomy is a catheter-based procedure in which a diamond-coated crown orbiting inside an artery sands away severely calcified plaque to enlarge the lumen and ease stent delivery.
Patch angioplasty
Patch angioplasty is a vascular surgery technique that widens a narrowed artery by sewing in a patch of vein, bovine pericardium, or synthetic material, chiefly after carotid endarterectomy.
Percutaneous angioplasty
Percutaneous angioplasty is a minimally invasive procedure in which a balloon-tipped catheter is inflated inside a narrowed artery to compress plaque and restore blood flow, usually followed by a stent.
Percutaneous sclerotherapy
Percutaneous sclerotherapy is a minimally invasive procedure that injects a sclerosing agent into varicose veins and vascular malformations, destroying the vessel lining so it scars into a fibrous cord.
Prostatic artery embolization
Prostatic artery embolization (PAE) is an interventional radiology procedure that blocks arteries supplying the prostate, shrinking the gland to relieve urinary symptoms of benign prostatic hyperplasia.
Recanalization
Recanalization is the reopening of an occluded blood vessel, the central goal of stroke reperfusion therapy, achieved through thrombolysis or mechanical thrombectomy within hours of onset.
Renal angioplasty
Renal angioplasty is a catheter-based procedure that widens a narrowed renal artery with balloon dilation and often a stent, used for renovascular hypertension and ischemic nephropathy.
Splenorenal shunt
A splenorenal shunt is a surgical operation connecting the splenic vein to the left renal vein, lowering portal pressure to control variceal bleeding; the selective distal form dates to 1967.
Stent graft implantation
Stent graft implantation is an endovascular procedure in which a fabric-covered metal scaffold is placed inside a blood vessel to exclude aneurysms, first reported by Juan Parodi in 1991.
Stent implantation
Stent implantation is a percutaneous procedure in which a small metal mesh tube is expanded inside a narrowed coronary artery to hold the vessel open and restore blood flow.
Stent retriever thrombectomy
Stent retriever thrombectomy is an endovascular procedure that removes a clot from a cerebral artery by deploying a stent-like mesh across it and withdrawing the device.
Surgical Arteriovenous Shunt
A surgical arteriovenous shunt is a surgical connection allowing blood to flow directly from an artery to a vein, used to provide long-term access for hemodialysis.
Surgical Portacaval Shunt
Surgical portacaval shunt (portacaval anastomosis, Eck fistula) is an operative connection between the portal vein and inferior vena cava, introduced by Whipple in 1945, that decompresses varices in portal hypertension but causes encephalopathy; largely replaced by TIPS.
Thoracic endovascular aortic repair
Thoracic endovascular aortic repair (TEVAR) is a minimally invasive technique that treats descending thoracic aortic disease with a stent graft, first performed at Stanford in 1992 and the standard of care for complicated type B dissection.
Thoracoabdominal aortic aneurysm repair
Thoracoabdominal aortic aneurysm repair is the surgical or endovascular treatment of aneurysms spanning the thoracic and abdominal aorta, classified by Crawford extent and aimed at preventing rupture.
Thrombectomy
Thrombectomy, also called aspiration thrombectomy, is an image-guided procedure that removes a blood clot from a vessel, used mainly for acute ischemic stroke within 24 hours of onset.
Thromboendarterectomy
Thromboendarterectomy is a surgical procedure removing obstructive material, such as thrombus or plaque, from an artery along with its diseased inner wall layers, chiefly for stroke prevention and pulmonary hypertension.
Vascular bypass
A vascular bypass is surgery that reroutes blood flow around a blocked artery using a vein or synthetic graft, most often for peripheral artery disease or coronary blockages.
Vascular grafting
Vascular grafting is a surgical procedure that replaces or bypasses a blocked or aneurysmal blood vessel with a vein, synthetic, or biological conduit, used for peripheral artery disease.
Vein ablation
Vein ablation is a minimally invasive procedure that closes diseased, refluxing superficial veins, most often the saphenous veins, using laser or radiofrequency heat delivered through an ultrasound-guided catheter.
Vein stripping
Vein stripping is a surgical operation that removes an incompetent superficial vein trunk, usually the great saphenous vein, to cure venous insufficiency and varicose veins.
Venous anastomosis
Venous anastomosis is a surgical procedure that connects two veins to restore or redirect blood flow, sewn by hand or joined with a ring-and-pin coupler in flap reconstruction, replantation, and organ transplantation.
Venous reconstruction
Venous reconstruction is a set of open surgical techniques that repair or rebuild veins using sutures, patches, or grafts, restoring venous outflow after tumor resection, trauma, or chronic venous obstruction.
