In early stages (TASC [Trans-Atlantic Inter-Society Consensus] II A/B), these stenoses can be successfully treated by endovascular procedures. For more complex aortoiliac stenoses (TASC II C/D), open surgical treatment was the primary treatment in the past.Clinical issue: Because of the advanced age and multiple comorbidities of PAD patients with complex aortoiliac stenoses, open surgical treatment is usually associated with high risk, and therefore endovascular procedures are an alternative despite their poorer outcome. Covered endovascular reconstruction of the aortic bifurcation (CERAB) aims to improve the primary patency rate compared with the usual endovascular implantation of kissing stents.Data: With regard to the primary patency rate, open surgical treatment remains superior to both endovascular procedures; however, the CERAB technique shows a better 5‑year outcome than the kissing stent technique. No differences are found in the secondary patency rate for any of the three procedures. The morbidity and mortality of the CERAB and kissing stent techniques are comparably low, and both procedures are superior to open surgical treatment.Conclusion: Because of the better long-term outcome of the CERAB versus the kissing stent technique, it should be used in patients with complex aortoiliac stenoses with increased risk of complications expected with open surgical treatment.","PeriodicalId":29778,"journal":{"name":"Radiologie","volume":"62 1","pages":"601-606"},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42401986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of those affected are men over the age of 65. The ideal imaging technique for diagnosis, treatment planning and follow-up is computed tomography (CT) angiography. Below a diameter of 4 cm, the risk of rupture is 6.3%, and then increases significantly with increasing diameter. Today, treatment is recommended from a size of 3.5 cm at the earliest.Therapy: Because of the lower mortality, endovascular therapy is the leading treatment for the elective and emergency situation. The quality of the landing zones, which are important for sealing, is decisive for elimination of the aneurysm. The elimination is carried out by means of stent grafts, often in combination with embolization. Due to the risk of buttock claudication and erectile dysfunction, the preservation of ipsilateral pelvic perfusion is recommended in cases of insufficient collateralization. Special iliac branch devices or various parallel endograft techniques are available for this purpose.Follow-up: The main problem of endovascular treatment are endoleaks and the associated need for reintervention. Imaging control by means of CT angiography is crucial for timely endoleak detection, especially in the early phase.","PeriodicalId":29778,"journal":{"name":"Radiologie","volume":"62 1","pages":"607-613"},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46363545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
