In modern clinical practice, EVT for PAD is the first line treatment. However, SAF long CTO lesion of the TASC C/D remains the major limitation of EVT. It has not been proved the decisive superiority of stent strategy for those lesions. Therefore, we compared the results of two strategies Balloon angioplasty and Primary stent strategy for SFA long CTO lesions. 164 lesions in 156 patients (72 years, 72% of male, lesion length: 19.2±3.8 cm) were received EVT for long CTO lesion of SFA. We divided into two groups according to procedure strategies (Balloon angioplasty strategy:57 lesions, Primary stent strategy: 107 lesions). There was no difference in CD-TLR rate at 1-year between both strategies (Balloon angioplasty strategy 64.9% vs. Primary stent strategy 72%; p=0.13). Furthermore, regarding lesions with CLI and TASC D lesions, there were no difference in CD-TLR rate at 1-year between both strategies (72.0% vs. 56.8%; p=0.5, 64.3% vs. 72.3%; p=0.15) . This finding suggested that Leaving nothing behind strategy might be the appropriate strategy.
Coral reef aorta (CRA) is calcified stenosis localized in pararenal abdominal aorta. We report three endovascular therapy (EVT) cases for CRA. All three patients were admitted to our hospital with intermittent claudication. CT showed calcified stenosis around the inferior mesenteric artery in two cases, and the superior mesenteric artery in one. Luminexx® 14 mm deployments were successfully performed for these patients. EVT for CRA is low invasive and efficient as open surgery. Post-therapeutic follow-up is essential and prompt re-intervention if necessary should be performed to improve the long-term results.
