After showing significantly lower complication rates in diagnostic coronary angiography, the radial artery access was successfully introduced as a useful vascular access site for transradial percutaneous coronary intervention in order to enhance patients' comfort and reduce hospital workload and costs. Moreover, due to the reduced need for antiplatelet therapy cessation as a result of lower bleeding complications, patients treated with transradial access showed a significantly better cardiac outcome in randomized interventional acute coronary syndrome studies.Procedural success and postprocedural radial arteritis or radial occlusions are closely related to anatomical circumstances (e.g., anomalous radial branching patterns, tortuosity, e.g., radial loops and small radial artery diameters), or risk factors for radial spasms (e.g. smoking, anxiety, vessel diameter, age, gender) which can effectively be reduced by the use of smaller catheters (4-5 Fr) and the administration of an adjuvant pharmacological therapy before (3000 U heparin, verapamil, nitroglycerine) and after (ibuprofen) the intervention.For successful radial sheath access and transradial catheterization, it is important to use dedicated radial access needles ≤21-gauge and steel wires ≤0.018 in. In order to pass the brachiocephalic trunk without difficulties or complications and access the ascending aorta, the use of inspiration maneuvers is of central importance.

Percutaneous transluminal procedure for removing atheromatous plaque from the coronary arteries. Both directional (for removing focal atheromas) and rotational (for removing concentric atheromatous plaque) atherectomy devices have been used.
Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, ANGIOPLASTY, TRANSLUMINAL, PERCUTANEOUS CORONARY is available.
Surgical excision of the gingiva at the level of its attachment, thus creating new marginal gingiva. This procedure is used to eliminate gingival or periodontal pockets or to provide an approach for extensive surgical interventions, and to gain access necessary to remove calculus within the pocket.

Dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.
Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.
