Purpose: A hybrid aortic repair using the frozen elephant trunk (FET) technique with an open distal anastomosis in zone 2 and debranching of the left subclavian artery (LSA) has been demonstrated to be favorable and safe. Although a transposition of the LSA reduces the risk of cerebellar or medullar ischemia, this may be challenging in difficult LSA anatomies. Case Report: We present the case of a 61-year old patient with DeBakey I aortic dissection, treated with FET in moderate hypothermic circulatory arrest (26°C) and selective cerebral perfusion using a Thoraflex-Hybrid (Vascutek Terumo) prosthesis anchored in zone 2, with overstenting of the LSA orifice and no additional LSA debranching. Sufficient perfusion of the LSA was proved intraoperatively using LSA backflow analysis during selective cerebral perfusion in combination with on-site digital subtraction angiography (ARTIS Pheno syngo software). No neurologic dysfunction or ischemia occurred in the postoperative course. An angiographic computed tomography revealed physiologic LSA perfusion, with subsequent thrombotic occlusion of the false lumen in the proximal descending aorta after 7 days. Conclusion: Using an angiography-guided management in patients with complex DeBakey I dissection and difficult anatomy may simplify a proximalization of the distal anastomosis in zone 2 for FET, even without an additional LSA debranching.

Background: Stroke is a severe complication of patients with type B aortic dissection (TBAD) after thoracic endovascular aortic repair (TEVAR). Our aim is to identify predictors of stroke after TEVAR.Methods: From February 2016 to February 2019, 445 patients with TBAD who underwent TEVAR were retrospectively analyzed. Univariate and multivariate analyses were performed to identify predictors of stroke after TEVAR.Results: The total incidence of stroke was 11.5%, with transient neurological dysfunction (TND) of 10.6% and permanent neurological dysfunction (PND) of 0.9%. The average age of the patients was 53.0 ± 3.2 years, and the male/female ratio was 1.17. Univariate analysis suggested that age, body mass index (BMI), diabetes mellitus, chronic obstructive pulmonary disease (COPD), the urgency of repair, type of anesthesia, and left subclavian artery (LSCA) processing were potential risks factors of stroke after TEVAR. Multiple logistic regression identified that LSCA coverage (OR = 5.920, 95% CI: 2.077–16.878), diabetes mellitus (OR = 3.036, 95% CI: 1.025–8.995), and general anesthesia (OR = 2.498, 95% CI: 1.002–6.229) were independent predictors of stroke after TEVAR.Conclusions: Left subclavian artery (LSCA) coverage, diabetes mellitus, and general anesthesia were independent risk factors of stroke after TEVAR for TBAD.

Mycotic subclavian aneurysms are rare, and their presence typically mandates urgent repair due to the associated high risk of rupture and mortality. A multi-disciplinary team effort is of utmost importance in ensuring favorable results. In this case report, we present a 79-year-old male with a rapidly enlarging mycotic left subclavian artery aneurysm secondary to a retrosternal abscess and left sternoclavicular septic arthritis, who underwent aneurysmal exclusion, a left carotid-left axillary bypass and pectoralis muscle flap coverage with a good outcome.

ABSTRACT Objective: To describe an infant with craniofacial microsomia and recurrent respiratory distress associated with aberrant right subclavian artery in order to review its most frequent congenital anomalies and alert the pediatrician to its rarer and more severe complications. Case description: This case report involves an 18-month-old male infant, only son of non-consanguineous parents. At birth, the child presented craniofacial dysmorphisms (facial asymmetry, maxillary and mandibular hypoplasia, macrostomia, grade 3 microtia, and accessory preauricular tag) restricted to the right side of the face. Additional tests showed asymmetric hypoplasia of facial structures and thoracic hemivertebrae. No cytogenetic or cytogenomic abnormalities were identified. The patient progressed to several episodes of respiratory distress, stridor, and nausea, even after undergoing gastrostomy and tracheostomy in the neonatal period. Investigation guided by respiratory symptoms identified compression of the esophagus and trachea by an aberrant right subclavian artery. After surgical correction of this anomaly, the infant has not presented respiratory symptoms and remains under multidisciplinary follow-up, seeking rehabilitation. Comments: Craniofacial microsomia presents a wide phenotypic variability compared to both craniofacial and extracraniofacial malformations. The latter, similarly to the aberrant right subclavian artery, is rarer and associated with morbidity and mortality. The main contribution of this case report was the identification of a rare anomaly, integrating a set of malformations of a relatively common condition, responsible for a very frequent complaint in pediatric care.

Purpose: To describe a technique of vascular plug penetration by a guidewire with a heavy tip load for additional embolization of a type 2 endoleak after endovascular aortic aneurysm repair (EVAR). Technique: The technique of vascular plug penetration is effective for additional embolization of a type 2 endoleak, when large arteries such as left subclavian artery (LSA) or hypogastric artery remain patent even after the embolization of the vessel has been performed using a vascular plug and are responsible for the endoleak. A tapered guidewire with a heavy tip load enables the penetration of the disk of the plug, followed by introduction of a microcatheter into the endoleak nidus. In the presented case, the technique successfully eliminated a type 2 endoleak in a thoracic aortic aneurysm for which a patent LSA despite the embolization by a vascular plug was responsible. Conclusion: The technique of vascular plug penetration allows an access to an endoleak cavity via a vascular plug placed in an aortic side branch for additional embolization of a type 2 endoleak after EVAR.
