Total endovascular repair of an intraoperative stent-graft deployed in the false lumen of Stanford type A aortic dissection: A case report. | LitMetric
Background: A 46-year-old male underwent ascending aortic replacement, total arch replacement, and descending aortic stent implantation for Stanford type A aortic dissection in 2016. However, an intraoperative stent-graft was deployed in the false lumen inadvertently. This caused severe iatrogenic thoracic and abdominal aortic dissection, and the dissection involved many visceral arteries.
Case Summary: The patient had pain in the chest and back for 1 mo. A computed tomography scan showed that the patient had secondary thoracic and abdominal aortic dissection. The ascending aortic replacement, total arch replacement, and descending aortic stent implantation for Stanford type A aortic dissection were performed 2 years prior. An intraoperative stent-graft was deployed in the false lumen. Endovascular aneurysm repair was performed to address this intractable situation. An occluder was used to occlude the proximal end of the true lumen, and a covered stent was used to direct blood flow back to the true lumen. A three-dimensional printing technique was used in this operation to guide pre-fenestration. The computed tomography scan at the 1mo after surgery showed that the thoracic and abdominal aortic dissection was repaired, with all visceral arteries remaining patent. The patient did not develop renal failure or neurological complications after surgery.
Conclusion: The total endovascular repair for false lumen stent-graft implantation was feasible and minimally invasive. Our procedures provided a new solution for stent-graft deployed in the false lumen, and other departments may be inspired by this case when they need to rescue a disastrous stent implantation.

Aortic dissection (AD) represents a critical condition characterised by a tear in the inner lining of the aorta, leading to the leakage of blood into the layers of the aortic wall, posing a significant risk to life. However, the pathogenesis is unclear. In this study, scRNA-seq was applied to cells derived from aortas of both AD and non-AD donors (control) to unveil the cellular landscape.

Aortic aneurysm is a common cardiovascular disease. Over time, the disease damages the structural and functional integrity of the aorta, causing it to abnormally expand and potentially rupture, which can be fatal. Sex differences are evident in the disease, with men experiencing an earlier onset and higher incidence.
Background: Aortic dilation, cardiac malformations and hypertension are known risk factors for aortic dissection in Turner syndrome (TS). In the current guidelines, rapid growth of the aorta has been added as a risk marker. This study aimed to estimate the growth of the ascending aorta over time, to identify risk factors of aortic growth, and to describe aortic complications in TS.

Background: Thoracic aortic dissection (TAD) is an uncommon complication in patients with Tetralogy of Fallot (TOF). Information concerning risk factors for TAD in patients with TOF is very limited.
Methods: We report a case of Stanford type A TAD in a female patient with previously repaired TOF.
Background: Double aortic arch (DAA) with type B aortic dissection in adults is a rare aortic vascular disease. The abnormal anatomical structure of the aortic arch in such patients presents significant challenges in the selection of surgical approaches, and there is a notable lack of exploration into endovascular repair approaches that simultaneously preserve asymptomatic vascular rings.
Case Description: A 43-year-old female patient was admitted due to recurrent chest and back pain lasting for over a month.
