Percutaneous transluminal angioplasty of visceral arterial stenoses: results and long-term clinical follow-up.
OBJECTIVE
To determine the efficacy and safety of percutaneous transluminal angioplasty (PTA) of the visceral arteries.


METHODS
We retrospectively evaluated the results of PTA performed in 20 visceral arteries in 19 patients (10 men, nine women; mean age, 63 years). Eleven patients had symptoms characteristic of mesenteric ischemia, four had atypical abdominal pain, and four were undergoing prophylactic dilation before undergoing another procedure involving the abdominal aorta. Clinical follow-up was possible in all patients.


RESULTS
PTA was technically successful in 15 of 19 patients (79%); among these 15 patients, 12 (80%) did well clinically. Of the seven PTA procedures that were immediate failures, five failed secondary to an occult malignancy or to extrinsic arterial compression by the median arcuate ligament. Ten (83%) of the 12 patients in whom the procedures were immediate clinical successes are still clinically improved at 4-73 months follow-up (mean, 25 months). PTA was successful in only one of the four patients who had symptoms atypical of mesenteric ischemia, but it was successful in 11 of the 15 patients who had symptoms of mesenteric ischemia or who underwent prophylactic dilation. Major complications occurred in three (16%) of the 19 patients.


CONCLUSIONS
PTA of visceral artery stenoses is effective in patients with symptoms of mesenteric ischemia. It is also effective as prophylaxis in patients undergoing additional procedures in the abdominal aorta.
