UNASSIGNED: The current study aims to report midterm results of patients treated with endovascular intervention, kissing stent, or covered endovascular reconstruction of the aortic bifurcation, for Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation.
UNASSIGNED: Eighteen patients who have intermittent claudication or chronic limb threatening ischemia with Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation enrolled to the study between January 2018 and January 2021. Kissing stents, Advanta V12 (Atrium, Getinge Group), were used in 13 patients, and the covered endovascular reconstruction of the aortic bifurcation technique was used in 4 patients to reconstruct the aortic bifurcation. The patients were followed for a median of 49 months (min. 2, max.58 months). Patency rates, mortality, morbidities, and reinterventions were recorded.
UNASSIGNED: The mean age of the patients was 60.4 ± 10 years. Technical success was achieved in 94.4% of the patients, but one patient had to convert to open surgery. Primary patency rate of the remaining patients was 85.6% at 58 months. Target lesion revascularization rate was 11.7%. One patient had successful reintervention for in stent restenosis, and secondary patency rate was 93.3% at 58 months. Limb salvage rate was 84.6% during the follow-up. Two patients had myocardial infarction (11.1%) and one mortality (5.6%) occurred because of cerebrovascular event in the follow-up.
UNASSIGNED: Endovascular techniques can be used safely for reconstruction of the aortic bifurcation in Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease in selected patients who have high risk for open surgery. Covered endovascular reconstruction of the aortic bifurcation is the only technique that showed patency rates approaching open surgery in treatment of aortoiliac occlusive disease involving the aortic bifurcation to date. Although promising patency results were achieved with kissing-covered stents, long-term patency rates were still lower than those achieved with open surgery. Further randomized controlled studies comparing the long-term results of these techniques are needed.

UNASSIGNED: To study and compare the clinical outcomes of endovascular therapy with those of hybrid surgery in the treatment of Trans-Atlantic Inter-Society Consensus II (TASC II) D aortoiliac occlusive disease (AIOD).
UNASSIGNED: Patients with TASC II D-type AIOD who underwent their first surgical treatment at our hospital between March 2018 and March 2021 were enrolled and followed up to evaluate the improvement in symptoms, complications, and primary patency. The Kaplan-Meier method was used to compare the differences in primary patency between the treatment groups.
UNASSIGNED: In total, 132 of 139 enrolled patients (94.96%) achieved technical success following treatment. The perioperative mortality rate was 1.44% (2/139), and postoperative complications occurred in two patients. Among the patients who successfully underwent surgery, 120 underwent endovascular treatment (110 patients with stenting and 10 patients with thrombolysis before stenting), 10 underwent hybrid surgery, and 2 underwent open surgery. The follow-up data were compared between the endovascular and hybrid groups. At the end of the follow-up period, the patency rates in the hybrid and endovascular groups were 100% and 89.17% (107/120), respectively. The endovascular group achieved primary patency rates of 94.12%, 92.44%, and 89.08% at 6, 12, and 24 months postoperatively, respectively, whereas the primary patency rate remained at 100% in the hybrid group, with no significant variation between the endovascular and hybrid groups (P = 0.289). The endovascular group was further divided into a stent subgroup (110 patients) and a thrombolysis/stent subgroup (10 patients), and no prominent variation was noted in the primary patency between the two subgroups (P = 0.276).
UNASSIGNED: Although open surgery is the gold standard treatment for TASC II D-type AIOD, endovascular and hybrid treatments are feasible and effective. Both methods showed good technical success and early to midterm primary patency rates.

OBJECTIVE. The purpose of this study is to compare the clinical and safety outcomes between two groups of patients with Trans-Atlantic Inter-Society Consensus class D (TASC II D) aortoiliac occlusive disease (AIOD): those with higher-risk comorbidity who underwent endovascular reconstruction and those with lower-risk comorbidity who underwent surgical bypass. MATERIALS AND METHODS. Thirty-two consecutive patients with symptomatic TASC II D AOID who underwent surgical bypass or endovascular reconstruction from 2012 to 2017 were retrospectively reviewed. Lesion characteristics, technical approach, survival, limb salvage, patency, and change in clinical symptoms were analyzed. RESULTS. Nineteen patients with higher comorbidity underwent endovascular reconstruction, whereas 13 patients with lower comorbidity underwent surgical bypass. Patients undergoing endovascular reconstruction had an older median age (67.0 vs 62.0 years; p = 0.007), higher rates of hypertension (94.7% vs 61.5%; p = 0.018) and coronary artery disease (26.3% vs 0%; p = 0.044), and advanced renal impairment (mean [± SD] chronic kidney disease stage, 1.4 ± 1.5 vs 0.7 ± 1.3; p = 0.005). There were no significant differences in Rutherford classification between the groups. During long-term follow-up of 2.76 years, endovascular reconstruction and surgical bypass showed equivalent rates of survival (89.5% vs 84.6%; p = 0.683), limb salvage (100.0% vs 92.3%; p = 0.219), and primary or primary-assisted patency (85% vs 85%; p = 0.98). Groups showed similar clinical improvements in walking distance, rest pain, and tissue loss at 30 days (95% vs 85%; p = 0.158) and at long-term follow-up (74% vs 62%; p = 0.599). CONCLUSION. For properly selected patients, the clinical outcomes of endovascular reconstruction versus surgical bypass for TASC II D AOID may be equivalent at 2.5 years after the procedure. The decreased operative risk associated with endovascular reconstruction suggests that it is the technique of choice for high-risk patients.
