ABSTRACT
We present the case of a patient with chronic type B aortic dissection with a previous iliac to visceral debranching graft and thoracoabdominal endograft who, because of a type Ib endoleak and aortic diameter enlargement, required a complex solution involving placement of a thoracic endovascular graft inside a Dacron graft with a 180° curved shape in three-stage surgery. At 9 months of follow-up, he had no evidence of type I endoleaks, and the aortic diameter had decreased.
ABSTRACT
BACKGROUND: Due to population aging and the spread of endovascular techniques for aortic diseases, there has been an increase in older population intervened. Objectively assessing patient's global status becomes mandatory in advanced ages, as impaired functional status and frailty are associated with higher postoperative mortality rates. The aim of this paper is to evaluate the impact of a systematic geriatric preoperative assessment on the outcomes of aortic interventions. METHODS: All patients above 60 years old with surgical indication for aortic disease between September 2016 and May 2019 underwent a standardized geriatric assessment. It analyzed physiological reserve, frailty, and life expectancy. An algorithm was created for its application before intervention indication. Variables registered were patient's data, type of aortic disease, type of intervention, geriatric assessment result, mortality and follow-up time. A bivariate analysis was performed. RESULTS: One hundred forty-four patients were included. Geriatric report was unfavorable for intervention in 6.25% (N.=9). From these, 88% (N.=8) were finally rejected for intervention. In those undergoing aortic intervention (N.=127) there was a 7% mortality rate (N.=9) and in the no-intervention group (N.=17) mortality rate raised up to 35% (N.=6). No aortic-related mortality was reported. A relevant association between an unfavorable geriatric report and mortality was found "OR 0.036 (CI 0.0082-0.155)." A protective relationship between any aortic intervention and mortality was found, with OR 0.139 (CI 0.043-0.447). CONCLUSIONS: Geriatric assessment is a valid tool to estimate life expectancy and patient's physiological status. An unfavorable report correlates with short-term non-aortic mortality independently of undergoing intervention. This has a high clinical relevance, and it highlights its practical applicability to improve aortic surgery indication's quality and optimize resource investment.

BACKGROUND: Ureteroarterial fistula (UAF) represents an uncommon complication after urological surgery; however, this is a well-documented condition in patients with predisposing risk factors. The aim of the present study is to report and analyze the endovascular management of a series of patients with UAF, treated in authors' hospital, and to report and analyze the same data concerning patients retrieved from a systematic literature review. METHODS: Authors conducted a retrospective analysis of prospectively collected data and a systematic literature review. The research was carried out through PubMed database searching the following keywords: "uretero arterial fistula" and "uretero iliac fistula." It includes only articles reporting the endovascular management. RESULTS: Forty-six articles were included in the present study for a total of 94 patients. Risk factors were as follows: chronic indwelling ureteral stents, pelvic surgery, radiotherapy, iliac artery pseudo-aneurysm, and chemotherapy. All patients had gross hematuria at presentation. Stent graft placement was performed in 89 patients, embolization in 5 patients, and iliac internal artery embolization combined with stent graft placement was performed in 24 patients. Four postprocedural complications were observed (4.2%). During a median follow-up of 8 months, 10 complications related to UAF were observed (10.6%): rebleeding (7 cases) and stent thrombosis (3 cases). Two patients died for causes related to UAF (2.1%): rebleeding (1) and retroperitoneal abscess (1). CONCLUSION: Based on the present data, endovascular treatment is feasible and safe with low postprocedural complications and mortality rate. Considering the increase in surgery and radiotherapy performed, UAF should be always debated in patients with massive hematuria.
