Endovascular repair of the thoracic aorta.
[Endovascular repair of the thoracic aorta]. Presse Med. 2018 Feb 23;: Authors: Canaud L, Alric P Abstract Degenerative aneurysms of the thoracic aorta are increasing in prevalence. The recognition of the decreased morbidity of this approach compared with open repair was readily apparent, as it avoided left thoracotomy, aortic cross-clamping, and left heart bypass. Repair of isolated descending thoracic aortic aneurysms using stent grafts was introduced in 1995, and in an anatomically suitable subgroup of patients with thoracic aortic aneurysm, repair with endovascular stent graft provides favorable outcomes, with decreased perioperative morbidity and mortality relative to open repair. The cornerstones of successful thoracic endovascular aneurysm repair are appropriate patient selection, thorough preprocedural planning, and cautious procedural execution. Since then, TEVAR is increasingly being used for other aortic pathologies such as complicated type B dissection, traumatic aortic transection, and aneurysmal disease extending into the arch or visceral segment, requiring debranching procedures.

Abstract The pathogenesis of ascending thoracic aortic aneurysm (aTAA) is thought to differ between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV), and one of the causes is different hemodynamics. Influenced by hemodynamics, the tissue levels of proteins associated with aTAA might differ between aTAAs with BAV and TAV and between different localities within the aortic wall. We therefore analyzed aTAA tissue levels of MMP-2 (matrix metalloproteinase-2) isoforms (Pro-MMP-2, active MMP-2, and total MMP-2) and tissue levels of MMP-14, TIMP-2 (tissue inhibitor of metalloproteinase-2), MMP-9,...
Conclusion: The results of our study did not support associations between MMP1, MMP9, COL1A1, and COL1A2 genetic variants with the risk of thoracic artery disease in Polish patients. However, rs1799750 MMP1 and rs3918242 MMP9 seem to be associated with the degree of aortic regurgitation. PMID: 33029260 [PubMed - in process]
Yale Medicine vascular surgeons treat at least 80% of aortic aneurysms with minimally invasive approaches —and that includes some of the most complicated cases.
We report a case of a 92-year-old man who came to the neurologist outpatient department due to left buttock pain and numbness that radiated to the left lower leg in the recent 6 months and progressed rapidly over 10 days. Diagnosis: We arranged magnetic resonance imaging for lumbar nerve lesion. Magnetic resonance imaging showed a common iliac artery mycotic aneurysm, at about 6.3 cm in diameter, which compressed the psoas muscle, nerve plexus, and vein. Interventions: We used a left-side iliac bifurcation stent graft of 12 mm in diameter for aneurysm repair. An internal iliac artery with a stent graft of 10 mm...
Low muscle mass is common in patients with abdominal aortic aneurysm (AAA) and is associated with reduced post-operative survival,1 frailty, and acute and chronic disease. AAA is due to connective tissue abnormalities influenced by enzymatic activity. Matrix metalloproteinases, which are implicated in this process, have also been shown to affect muscle development.2 It is unclear, however, if low muscle mass is related to the anatomy and evolution of AAA. It was hypothesised that low muscle mass, measured by total psoas area (TPA), is associated with certain features of aneurysmal disease in the abdominal aorta, which may ...
To evaluate the 30 day mortality of elective open complex abdominal aortic aneurysm (cAAA) repair and identify factors associated with death.
ConclusionSequential catheterization amid progressive deployment of the Zenith ® t-Branch™ device is an effective method of deployment of the device that ensures optimal positioning and secured catheterization of the target vessels.
We report the successful repair of a large ascending aortic pseudoaneurysm in a 62‐year‐old male with bovine arch anatomy and prior Type A dissection repair, presenting with contained rupture and a pulsatile c hest wall mass.
CONCLUSIONS: TSP1 contributes to aneurysm pathogenesis, at least in part, by suppressing TIMP1 expression, which subsequently enables inflammatory macrophages to infiltrate vascular tissues. PMID: 33028100 [PubMed - as supplied by publisher]
In this study, we w ill analyze the management of DIC post TEVAR and look at its presentation more extensively, as it is currently a topic that is poorly studied.
