    Summary
    This summary is machine-generated.

    Percutaneous transluminal angioplasty effectively treats renovascular hypertension caused by renal artery stenosis. This minimally invasive procedure significantly reduces blood pressure in most patients, offering a viable treatment option.

    Area of Science:

    • Interventional Cardiology
    • Nephrology
    • Vascular Surgery

    Background:

    • Renovascular hypertension, caused by renal artery stenosis, is a significant clinical challenge.
    • Percutaneous transluminal angioplasty (PTA) has emerged as a key therapeutic modality.
    • Increasing frequency of PTA use for managing renal artery stenosis and its complications.

    Purpose of the Study:

    • To evaluate the efficacy and long-term outcomes of PTA in patients with renovascular hypertension.
    • To identify factors influencing the success of PTA in this patient cohort.
    • To assess the impact of PTA on blood pressure control and renal function.

    Main Methods:

    • Retrospective analysis of 140 PTA procedures in 90 patients with 119 renal artery stenoses.

  • Inclusion of patients treated for hypertension and/or renal insufficiency.
  • Follow-up of blood pressure response for 1-52 months (mean 22 months).

    • Main Results:

    • An initial technical success rate of 95% was achieved.
    • Mean diastolic blood pressure decreased by 36.7 mm Hg post-treatment.
    • Among 80 hypertensive patients, 25 were cured, 47 improved, and 8 were non-responders.

    Conclusions:

    • PTA is technically feasible and clinically effective for treating renovascular hypertension.
    • Patient selection, appropriate balloon sizing, and initial procedural success are critical for long-term outcomes.
    • PTA offers a significant benefit in blood pressure reduction for patients with renal artery stenosis.
