| radiography, interventional | Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization. (12 Dec 1998) |

| interventional angiography | <cardiology, surgery> The surgical repair of a blood vessel. A balloon angioplasty is a noninvasive procedure where a balloon-tipped catheter is introduced into a diseased blood vessel. As the balloon is inflated, the vessel opens further allowing for improved flow of blood. (12 Nov 1997) |
| interventional radiology | The clinical subspecialty that uses fluoroscopy, CT, and ultrasound to guide percutaneous procedures such as performing biopsies, draining fluids, inserting catheters, or dilating or stenting narrowed ducts or vessels. (05 Mar 2000) |
| ultrasonography, interventional | Ultrasonography using invasive or surgical procedures. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions. (12 Dec 1998) |
| Belsey Mark IV procedure | A transthoracic hiatal hernia repair that restores the lower oesophageal sphincter zone to the high pressure region below the diaphragm. (05 Mar 2000) |
| Belsey Mark V procedure | A modified Belsey Mark IV procedure often employing pledgetted sutures performed for patients with hiatal hernia plus disordered oesophageal motility in whom an oesophageal myotomy is also needed. (05 Mar 2000) |
| Girdlestone procedure | Complete resection or excision of the head and neck of the femur. (05 Mar 2000) |
| Vineberg procedure | Implantation of the internal mammary artery into the myocardium to improve blood flow to the heart. (05 Mar 2000) |
| V-Y procedure | A flap in which the incision is made in a V shape and sutured in a Y shape to gain additional tissue. Synonym: V-Y plasty, V-Y procedure. (05 Mar 2000) |
| Gomori procedure | <procedure> Cytochemical staining procedure used to localise acid phosphatases. Depends upon the production of phosphate ions from organic phospho esters such as _ glycerophosphate. The phosphate in the presence of lead ions causes the formation of a precipitate of lead salt that is converted to the brown sulphide of lead by the action of yellow ammonium sulphide. (18 Nov 1997) |
| Chamberlain procedure | A limited left anterior thoracostomy for biopsy of the mediastinal nodes out of reach by cervical mediastinoscopy. Synonym: anterior mediastinotomy. (05 Mar 2000) |
| Rittenhouse-Manogian procedure | Enlarges the aortic annulus by incising the left coronary-noncoronary commissure down unto the anterior leaflet of the mitral valve. (05 Mar 2000) |
| Clagett procedure | For empyema, a two-stage surgical procedure for expediting treatment of chronic empyema. (05 Mar 2000) |
| Collis-Belsey procedure | A surgical method of treating oesophageal structure by creation of a neoesophagus and a fundoplication antireflux procedure. (05 Mar 2000) |
