Primary aortoenteric fistulas are rare with an incidence reported up to.07% at autopsy. Literature review yields few reported cases, and rarer still is a fistula between a normal thoracic aorta and the esophagus. Rather, 83% of cases are associated with an aneurysmal aorta and 54% involve the duodenum. Patients with aortoesophageal fistula (AEF) usually present with a triad of chest pain, dysphasia, and a herald bleed. Without treatment, AEFs will result in exsanguination and are universally fatal; even with traditional open surgical treatment, mortality is reported over 55%. The complex pathology of AEFs makes repair more challenging, given an infected field, friable tissue, and patients who are often hemodynamically unstable. Staged repair using endografts as initial treatment with the primary goal of controlling bleeding and preventing fatal exsanguination has been reported. We present a case where a descending thoracic aorta to esophageal fistula was repaired, and this strategy was utilized. [ABSTRACT FROM AUTHOR]

- Abstract
The prevalence of subclavian steal (defined as retrograde/bidirectional vertebral artery flow) in the general population and in patients undergoing cerebrovascular duplex ultrasound (CDUS) examinations is variable. This is the largest study to date to analyze the incidence of duplex-suggested subclavian steal in 5615 CDUS examinations over a 1-year period and to examine its clinical implications. All consecutive CDUS examinations performed over a 1-year period were analyzed for the presence of subclavian steal. Indications of testing, presence of posterior cerebral circulation/subclavian steal symptoms, and any interventions for subclavian steal were analyzed. A total of 171 of 5615 (3.1%) CDUS examinations were found to have subclavian steal (duplex-suggested). One hundred seventeen (2.1%) had retrograde flow and 54 (1%) had bidirectional flow. Of 171, 104 (60.8%) were left sided. Indications for CDUS were post-carotid endarterectomy/carotid artery stenting surveillance in 39 patients (22.8%), surveillance for progression of carotid stenosis in 76 patients (44.4%), transient ischemic attack/stroke in 26 patients (15%), asymptomatic screening/carotid bruit in 18 patients (10.5%), and isolated posterior cerebral circulation symptoms in 12 patients (7%). A total of 63% patients had associated >50% carotid stenosis. The mean arm Doppler pressure gradient was 32.2 mm Hg for asymptomatic patients vs 37 mm Hg for patients with posterior circulation symptoms (P =.3254). There were significant differences between the mean systolic arm pressure for patients with retrograde vs antegrade vs bidirectional flow (105 mm Hg vs 146 mm Hg vs 134 mm Hg, respectively, P <.0001). All patients with retrograde flow had >50% subclavian stenosis or occlusion (100 of 117 had subtotal/total occlusion) except for one patient. Meanwhile, 52 of 54 patients with bidirectional flow had >50% subclavian stenosis (6 of 54 with subtotal/total occlusion), whereas two patients were normal/<50% stenosis (P <.0001). Overall, 26 of 171 patients (15.2%) had interventions for disabling symptoms. Eleven of 26 of all interventions were for disabling arm claudication, and only 10 of 171 patients (5.8%) were intervened for disabling posterior circulation symptoms with complete resolution of symptoms in all except one. At a late follow-up with a mean of 18 months (range: 1-37 months), there was no late major stroke with only two lacunar infarcts (not subclavian steal related). There were also seven late deaths, none stroke related. The incidence of subclavian steal in patients who undergo CDUS is relatively rare. Most of these patients are asymptomatic and can be treated conservatively, and only a few may need intervention for disabling symptoms with good symptom resolution. [ABSTRACT FROM AUTHOR]

- Abstract
We previously reported the incidence of ≥50% and ≥80% carotid in-stent stenosis. In the present study, we analyzed the rate of progression of in-stent stenosis and clinical outcomes with longer follow-up. We performed a retrospective analysis of prospectively collected data for 450 patients who had undergone transfemoral carotid artery stenting with longer follow-up (mean, 70 months). The progression of in-stent stenosis was defined as stenosis advancing to a higher severity of disease (ie, from <50% to ≥50% and from ≥50% to ≥80%). Kaplan-Meier analysis was used to estimate the rate of progression from <50% to ≥50% and ≥50% to ≥80%, the overall rates of ≥50% and ≥80% in-stent stenosis, and survival at 1, 3, 5, and 10 years. At a mean follow-up of 70.3 months (range, 1-222 months), 121 of 446 patients (27%) had had progression to ≥50% and 39 (8.7%) to ≥80% in-stent stenosis. Of the 406 patients whose first duplex ultrasound findings were normal or showed in-stent stenosis of <50%, 82 had had progression from normal or <50% to ≥50% in-stent stenosis at a mean of 51.7 months (range, 1-213 months). Of the 121 patients with ≥50% stenosis, 14 (11.6%) had experienced progression to ≥80% at a mean of 33.6 months (range, 6-89 months). Of the 82 patients with progression from <50 to ≥50%, 10 (12%) had experienced a neurologic event (eight transient ischemic attacks [TIAs] and two strokes). Of the 14 with progression from ≥50% to ≥80%, 2 (14.3%) had experienced a TIA, and the remaining patients were asymptomatic. Of the 39 patients with ≥80% in-stent stenosis, 9 (23%) had experienced a neurologic event (eight TIAs and one contralateral stroke). Overall, 13 of the 121 patients with late ≥50% restenosis (10.7%) had experienced a neurologic event (10 ipsilateral TIA, 2 ipsilateral stroke, and 1 contralateral stroke. Thus, 12 of 446 patients (2.7%) had experienced an ipsilateral TIA or stroke at a mean follow-up of 70 months. The rates of freedom from <50% to ≥50% in-stent stenosis progression were 93%, 85%, 78%, and 66% at 1, 3, 5, and 10 years. The rates of freedom from progression from ≥50% to ≥80% in-stent stenosis were 89%, 81%, and 77% at 1, 3, and 5 years, respectively. The overall rates of freedom from ≥50% in-stent stenosis and ≥80% in-stent stenosis were 86%, 77%, 71%, and 59% and 96%, 93%, 91%, and 84% at 1, 3, 5, and 10 years, respectively. Finally, the stroke survival rates were 95%, 80%, 63%, and 31% at 1, 3, 5, and 10 years, respectively. The rate of progression of carotid in-stent stenosis was modest, with a low incidence of stroke events. Therefore, the use of duplex ultrasound surveillance after carotid artery stenting should be selective and its benefits and utility perhaps reevaluated. [Display omitted] [ABSTRACT FROM AUTHOR]
