Herein, we present a neonatal case of coarctation of the aorta, with aortic arch thrombus confirmed by echocardiography. We performed thrombus removal and aortic arch repair emergently. This critical condition necessitates quick preoperative evaluation with echocardiography. Moreover, postoperative evaluation using computed tomography is reasonable to assess an aortic arch configuration, and exclude the remnant thrombus.

Abstract Neonatal aortic thrombus is a rare and critical condition that can present mimicking severe coarctation of the aorta or interrupted aortic arch. Transcatheter thrombectomy for this lesion has not been well described. We report a premature neonate with an occlusive proximal descending aorta thrombus, who underwent transcatheter mechanical thrombectomy using an Amplatzer Piccolo PDA occluder (Abbott, North Chicago, IL, USA). The procedure was successful with no subsequent distal thromboembolic events.

Cervical Approach

Sternotomy is indicated when a goiter cannot be resected via a cervical incision, such as in the case of a substernal goiter extending beyond the aortic arch. In this article, we report a case of a large substernal goiter that was successfully removed using the cervical approach only. This is a case of a 68-year-old woman, diagnosed with goiter 20 years ago, who complained of a neck mass enlargement with associated cough. Pathological examination revealed no malignancy. Computed tomography (CT) scan showed an 11-cm thyroid mass reaching the level of the aortic arch. Preoperatively, we evaluated the substernal extent of the goiter via CT in the extended neck position to decide whether sternotomy was necessary. With the patient’s neck extended, the goiter withdraws cranially above the aortic arch. The mass was then removed via the cervical approach without sternotomy. Preoperative CT in the extended neck position was thus deemed helpful in deciding whether or not sternotomy was required.

Purpose: Zone 0 landing in thoracic endovascular aortic repair (TEVAR) has recently gained increasing attention for the treatment of high-risk patients. The aim of this study was to compare the outcomes of total endovascular aortic arch repair between branched TEVAR (bTEVAR) and chimney TEVAR (cTEVAR) in the landing zone (LZ) 0. Materials and Methods: This was a single-center, retrospective, and observational cohort study. From January 2010 to March 2020, 40 patients (bTEVAR, n=25; cTEVAR, n=15; median age: 79 years) were enrolled in this study, with a median follow-up period of 4.1 years. These patients were considered unsuitable for open surgical treatment. Results: All procedures were successful and no cases of conversion to open repair were noted during the 30-day postoperative period. The 30-day mortality was 2.5% (n=1; bTEVAR [0 of 25, 0%] vs cTEVAR [1 of 15, 6.7%]; p=0.375), the perioperative stroke rate was 10.0% (n=4; bTEVAR [4 of 25, 16.0%] vs cTEVAR [0 of 15, 0%], p=0.278), and type 1a endoleak rate was 15.0% (n=6; bTEVAR [0 of 25, 0%] vs cTEVAR [6 of 15, 40.0%], p=0.001). The risk factor for stroke was atheroma grade of ≥2 in the brachiocephalic artery (p<0.001). The risk factor for type 1a endoleak was cTEVAR (p=0.001). The 8-year survival rate was 49.9%. The aorta-related death-free rate and aortic event-free rate at 8 years were 94.4% (bTEVAR: 95.5% vs cTEVAR: 93.3%, p=0.504) and 60.7% (bTEVAR: 70.7% vs cTEVAR: 40.0%, p=0.048), respectively. Conclusions: Total endovascular aortic arch repair using bTEVAR and cTEVAR is feasible for the treatment of aortic arch diseases in high-risk patients who are unsuitable for open surgery. However, as the rate of stroke is high, strict preoperative evaluation to prevent stroke is needed. No rupture of the aneurysm was observed in cTEVAR, but patients should be selected carefully because of the high incidence of type 1a endoleak.

Increased Risk

Preoperative evaluation of maxillary sinus anatomy is very important to avoid surgical complications due to close anatomical relations between the sinus and the posterior maxillary teeth and/or edentulous alveolar ridge. Posterior superior alveolar artery is a branch of the maxillary artery and provides the vascularization of the lateral sinus wall and underlying mucosa. Maxillary artery branches should be taken into consideration during sinus lifting procedures and bone augmentation due to increased risk of bleeding by damaging the artery during the osteotomy. Computed tomography (CT) explores three-dimensional anatomic structures and provides complex and accurate information about them. Cone Beam Computed Tomography (CBCT) offers an accurate view of the teeth and surrounding structures at high resolution, despite low-dose radiation used. In this study, the incidence of anatomical variations and sinus pathology were assessed using CBCT. The aim is to evaluate the presence of sinus pathology (sinus mucosal thickening, oro-antral communications, sinus tumors, cysts, polyps), presence and position of the posterior superior alveolar artery. These issues are important because they are about the limits of the dental implants in the posterior maxillary area. The presence of sinus pathology and anatomical variations may predispose to complications and even failures of implantation therapy.
