| Abstract|| |
Complex iliac artery obstructions, particularly bilateral stenosis or total iliac artery occlusions, are usually treated with aortofemoral or aortobifemoral graft surgery. However, surgical treatment is associated with 3% mortality rate and significant morbidity such as intestinal ischemia, spinal cord injury, and ureteral damage. Percutaneous interventions of aortic bifurcation offer a promising alternative to surgery with potentially lower morbidity and mortality risk. We report a case of peripheral artery disease who had underwent right transfemoral iliac angioplasty with femoropopliteal bypass presented again with bilateral lower limb ischemia, who was successfully treated with stent implantation with the kissing balloon technique.

| Introduction|| |
Surgical treatment of aortoiliac occlusive disease is associated with excellent long-term results with a mortality rate of 3% and morbidity rate of 5–8%. Percutaneous interventions is a less invasive alternative to surgery with a good success rate.
Risks of contralateral embolism or contralateral iliac artery occlusion due to dislodgement of atherosclerotic or thrombotic material from aortic bifurcation during unilateral percutaneous transluminal angioplasty (PTA) are high. Kissing balloon technique wherein balloons are positioned simultaneously across both limbs of aortic bifurcation and inflated in unison prevents such a complication to develop. Although several series have reported good procedural and clinical success, the complication of dissection, thrombosis or significant residual stenosis remain up to 9%.
| Case Report|| |
A 45-year-old male patient presented with a history of intermittent claudication pain for the last 3 months and blackish discoloration of the right toe for 15 days. The patient is a known case of peripheral arterial disease, previously underwent right transfemoral iliac angioplasty with femoropopliteal bypass 1 year ago for similar complaints. He is also a smoker and diabetic, no family history of ischemic heart disease and peripheral vascular disease. Coronary angiogram revealed normal coronaries. On examination, blackish discoloration of the right middle toe, absent pulse in bilateral lower limbs. Computed tomography (CT) peripheral angiogram was revealed diffuse internal thickening with wall calcification noted in aorta causing 40% diameter stenosis, right common iliac artery (CIA) in-stent restenosis of 90% at proximal and distal edges of the stent [Figure 1]a, right femoropopliteal graft is thrombosed and left CIA shows multifocal areas of narrowing and occlusion of 90% [Figure 1]b. The patient was subjected for PTA, left CIA approached from the left brachial artery with 0.035 Terumo wire and exteriorized through left femoral artery [Figure 2]a. The right femoral arterial approach was used for deploying CIA stent. Serial predilatation was done using 8 mm × 55 mm peripheral balloon [Figure 2]b. A 8 mm × 120 mm medtronic self-expanding stent was deployed in the right CIA and 7 mm × 150 mm medtronic self-expanding stent deployed in left CIA. A postdilatation with simultaneous kissing at aortoiliac junction was done using 8 mm × 55 mm balloon in right CIA and 7 mm × 40 mm balloon in left CIA. Postprocedure showed good distal flow [Figure 3]. CT peripheral angiogram was done after 1 week which showed patent stent seen in relation to distal aorta, left CIA, external, right CIA [Figure 4].

| Discussion|| |
Aortoiliac occlusive disease has been traditionally treated with open aortobifemoral bypass which is burdened with perioperative mortality of 3–5% and morbidity of 10%. Percutaneous interventions offer a less invasive alternative to surgery with a high technical success rates and comparable long-term results especially in low-grade TransAtlantic Inter-Society Consensus lesions.
Aortic bifurcation stenting was first described by Palmaz et al. in a study of seven patients with an alternative percutaneous approach in which they delivered one iliac stent at a time. Kissing stent insertion in the aortic bifurcation can be achieved with excellent clinical success with minimal short and intermediate-term complications. Those with lesions localized to the aortic bifurcation may be best suited for the kissing stent technique even though patients with more extensive involvement of the aorta or external iliacs can be successfully treated with additional stents.
Early series of percutaneous recanalization procedures for chronic iliac artery occlusions demonstrated poor results and excessively high complication rates of up to 20%., Vorwerk et al. demonstrated that endovascular stents significantly contribute to an improvement in long-term results. A meta-analysis study of iliac artery intervention, stent placement was found to reduce the risk of long-term failure by 39% when compared with PTA alone, and the 4-year success rate for iliac angioplasty was approximately 44 to 65%.
According to Ballard et al., factors such as female sex, superficial femoral artery occlusion, perioperative vascular complications, and hypercholesterolemia proved to be risk factors for lower patency rates in iliac artery stents.
In the present case, the patient underwent balloon angioplasty, followed by primary stent implantation with the kissing balloon technique. All stents were placed, with successful restoration of the vessel patency both CIAs. The patient showed prompt recovery on follow-up at 6 months.
| Conclusion|| |
Endovascular treatment of aortoiliac disease with kissing stent is a promising method to restore circulation with low morbidity and mortality and good patency rates even in the setting of in-stent restenosis and a good alternative to surgery.
