Transradial Renal Artery Angioplasty and Stenting in a Patient With Leriche Syndrome

Abstract

SUMMARYPercutaneous interventional procedures in the renal arteries are usually performed employing a femoral or brachial vascular access. In contrast, the transradial approach has been established for coronary angiography and angioplasty. We encountered a patient with Leriche syndrome who had renovascular hypertension ascribed to a severe left renal artery stenosis. To stabilize his blood pressure, we made an attempt to relieve the renal artery stenosis with Leriche syndrome by transradial renal artery angioplasty and stenting, using devices for coronary intervention. The procedure was successful without complications or residual stenosis. His hypertension improved with less antihypertensive medications. This case suggests that the radial approach might become an alternative entry site for renal artery interventions. (Int Heart J 2005; 46: 557-562)

Feasibility and application of single 5F multipurpose catheter in coronary and peripheral angiography via a transradial approach

“…Similar benefits are also expected from the transradial access for cerebral angiography [6,7]. Some case reports have also shown the benefits of transradial approach in renal angiography [8].…”

“…Staying in bed for a long time can result in urinary retention, back pain and venous thrombosis that may become lethal [1,2]. Therefore the transradial approach has been suggested for coronary, cerebral and renal catheterizations [3][4][5][6][7][8]. Previous studies show that there is a close association between CAD and other arterial diseases, including cerebral arterial and renal stenoses.…”

Transradial Embolization of a Bleeding Renal Angiomyolipoma

“…Finally, this approach minimizes pelvic radiation. 15,17,18 There are also disadvantages to the use of the radial access route. The radial artery is smaller than the femoral artery (*2-3 mm compared with 7-10 mm), making radial access more technically challenging.…”

“…Lack of familiarity with this approach may be the main impediment to procedural success. 15,17,18 The Allen test should be documented in every patient undergoing a radial artery procedure. To perform this test, both the radial and ulnar arteries should be occluded so as to observe any obvious pallor of the hand.…”

“…13 More recent reports have shown that percutaneous renal artery angioplasties also could employ the radial approach as a vascular access site. 14, 15 We report the use of a transradial approach to embolize a hemorrhagic AML in a pregnant patient in order to prevent additional hemorrhage while minimizing pelvic radiation.…”
