Severe Reperfusion Therapies regarding Severe Ischemic Cerebrovascular accident.
The aim of the present study was to demonstrate the clinical outcomes of intentional coverage of the celiac artery (CA) during thoracic endovascular aneurysm repair (TEVAR).

The MEDLINE, EMBASE, and Cochrane Library databases were searched for studies reporting coverage of CA during TEVAR. The methodologic quality of the included studies was assessed using the Moga score and Newcastle-Ottawa scale. A random effects model was used to pool the estimates. A meta-analysis was performed with investigation of the following outcomes visceral ischemia, spinal cord ischemia (SCI), stroke, endoleak, reintervention, 30-day mortality, and 1-year mortality.

A total of 10 studies with 171 patients were included. The summary estimate rate of visceral ischemia events was 4.2% (95% confidence interval [CI], 0.9-8.9%; I
= 4.1%). The incidence of stroke and SCI was 0.2% (95% CI, 0%-3.4%; I
= 0%) and 3% (95% CI, 0.3%-7.4%; I
= 6.1%). The rate of endoleak during the follow-up period was 24.1% (95% CI, 14.3%-35.1%; I
= 20.0%). The reintervention rate was 13.6% (95% CI, 4.4%-25.7%; I
= 66.0%). The 30-day and 1-year mortality were 2.9% (95% CI, 0.3%-7.2%; I
= 6.2%) and 15.2% (95% CI, 7.8%-23.9%; I
= 0%).

Among the patients with complex thoracic aortic pathologies deemed at high risk for open reconstruction, TEVAR with intentional coverage of the CA is a safe and feasible option to extend the distal sealing zone with acceptable rates of visceral ischemia, SCI, type II endoleak from the CA, and 30-day mortality.

On February 17, 2021, Medtronic Incorporated issued a global voluntary recall of the Valiant Navion Thoracic Stent Graft System (the device under study in the Valiant Evo Global Clinical Program that is the subject of this publication), and instructed physicians to immediately cease use of the Valiant Navion system and return any unused product. Medtronic initiated the recall in response to three clinical trial subjects recently observed with stent fractures, two of whom have confirmed type IIIb endoleaks. The data collection, analysis, and manuscript submission occurred before the notice of this recall, and, specifically, the 100 procedures reviewed for this series were free of events at 1year related to the reason for this device recall. The authors of this article and the manufacturer were unaware of the recently detected adverse events at the time of the preparation of the manuscript, and the 1-year trial results, and imaging-based analyses described are unchanged. Management of thoracic aortic aneurysmreedom from mortality, endoleak development, and secondary procedures. Aortic elongation and dilation were more prevalent at the distal end, emphasizing the importance of distal attachment zone consideration as part of preoperative planning. Because aortic remodeling can be expected to continue over time, additional follow-up and imaging analysis in the trial will be necessary to assess the aortic morphology and its effects on stent graft performance.
Open surgical repair remains the gold standard treatment for popliteal artery aneurysms (PAA). The objective of this study was to evaluate the safety of external stenting and its medium-term effect on vein graft disease after open PAA repair.

Between December 2017 and September 2019, 12 consecutive patients with PAA underwent open surgical repair with externally stented saphenous vein grafts. Duplex ultrasound scanning of the grafts was performed at discharge and at 3, 6, and 12months after the procedure to evaluate graft patency, average lumen diameter and lumen uniformity.

Eleven patients underwent aneurysm ligation and bypass grafting and one patient was treated with aneurysm exclusion and interposition of a venous segment. External stenting of the vein graft was successful in all patients. The mean follow-up time was 12months (range, 7-17months), with a primary patency rate of 100% and no graft revisions or reinterventions. The mean lumen diameters at 3, 6, and 12months were 5.9± 1.2mm, 5.7± 0.8mm, and 5.7± 0.7mm, respectively, with no significant changes between 3 and 6 (P= .34) and between 6 and 12months (P= .34). The coefficient of variance at 3, 6, and 12months was 8.2± 9.3, 9.4± 7.2, and 10.4± 8.9, respectively, with no significant change between 3 and 6months (P= .78) or 6 and 12months (P= .98). No mortality or amputations were recorded throughout the follow-up period.

External stenting of vein grafts in open surgical repair of PAA is feasible and safe. This technique may potentially improve the outcomes of surgical repair in patients with PAA.

Contemporary national trends in the repair of ruptured abdominal aortic aneurysms (AAAs) and intact AAAs are relatively unknown. Furthermore, screening is only covered by insurance for patients aged 65 to 75years with a family history of AAAs and for men with a positive smoking history. Oleic in vivo It is unclear what proportion of patients who present with a ruptured AAA would have been candidates for screening.

Using the National Inpatient Sample from 2004 to 2015, we identified ruptured and intact AAA admissions and repairs using the International Classification of Diseases codes. We generated the screening-eligible cohort using previously identified proportions of male smokers (87%) and all patients with a family history of AAAs (10%) and applied these proportions to patients aged 65 to 75years. We accounted for those who could have had a previous AAA diagnosis (17%), either from screening or an incidental detection in patients aged >75years who had presented with AAA rupture. The primary outcomes were treatmen range should be considered.
Most patients who had undergone repair for ruptured AAAs did not qualify for screening. EVAR was the primary treatment of both ruptured and intact AAAs with relatively low in-hospital mortality. Therefore, expansion of the screening criteria to include selected women and a wider age range should be considered.
