The Current Role of Renal Angioplasty in the Treatment of Renovascular Hypertension

Use of external iliac artery in renal revascularization surgery: long-term angiographic assessment1 1Competition of interest: none.

“…In certain forms of fibrodysplasia, primarily those involving the tunica media of the arterial wall, excellent results are attained with endoluminal techniques. [16][17][18][19][20] However, other forms of the disease, eg, fibroplasia of the intima, are resistant to endoluminal intervention, with high rates of technical failure or recurrence of lesions. [21][22][23][24] It is, nevertheless, important to note that many of the studies published report only results obtained immediately after the procedure, and few report long-term results.…”

“…This is particularly important given that there are powerful biologic arguments that suggest these procedures are likely to fail, eg, myoproliferative response of the arterial wall to the injury caused by dilatation, and reaction to a foreign body triggered by presence of the stent. 16,17,25,26 Prosthetic substitutes are rarely used in isolated renal artery revascularization, 27,28 although they are more frequently used when the abdominal aorta must be replaced at the same time because of concomitant obstruction or aneurysm. 29,30 Prostheses of a caliber compatible with the renal artery are usually small in diameter, and they have low permeability indexes in different vascular territories, for reasons related to their thrombogenicity and biologic behavior.…”
