[Radiologically-guided dilatation in arterial stenosis of transplanted kidney]

Area of Science:

• Nephrology
• Vascular Surgery
• Interventional Radiology

Background:

• Transplanted kidney artery stenosis is a serious post-transplant complication.
• Treatment options include reconstructive surgery and radiologically-guided endovascular dilatation (RED).
• RED is considered the primary method of choice for managing this condition.

Purpose of the Study:

• To evaluate the effectiveness and outcomes of radiologically-guided endovascular dilatation (RED) for treating stenosis of the artery in transplanted kidneys.

Main Methods:

• The study involved 20 patients with transplanted kidney artery stenosis.
• Radiologically-guided endovascular dilatation (RED) was applied as the primary intervention.
• Outcomes were assessed in early and late post-procedural periods.

Main Results:

• Early post-RED results were good in 75% (15 patients) and satisfactory in 10% (2 patients).
• Technical complications led to RED failure in 3 cases (15%).
• Late-term restenosis occurred in 47% (8 patients), with repeat RED successful in 5 of these cases.

Conclusions:

• Radiologically-guided endovascular dilatation (RED) is an effective primary treatment for transplanted kidney artery stenosis, despite challenges.
• Restenosis is a significant concern requiring potential repeat interventions.
• Further research may explore strategies to improve long-term patency rates after RED.
