Bilateral arterial ducts feeding discontinuous pulmonary arteries are a very rare anatomic arrangement in complex heart malformations with pulmonary atresia. In this setting, neonatal ductal closure may result in abrupt pulmonary hypoperfusion and life-threatening systemic hypoxia. In high-risk patients, percutaneous arterial duct stenting might be an engaging and cost-effective alternative to surgery. This paper reports on a critical low-weight neonate with complex heart disease and discontinuous pulmonary arteries dependent on bilateral arterial ducts who underwent successful transcatheter ductal stenting as an alternative to a high-risk surgical palliation.

Evaluation of maxillary sinus pathologies and the posterior superior alveolar artery canal using cone-beam computed tomography.

Objective: This study aims to determine the anatomical relationship between the posterior superior alveolar artery (PSAA) and the lateral wall of the maxillary sinus during preoperative radiological evaluations in the posterior maxillary dental region, as well as to evaluate the prevalence of PSAA and its potential associations with sinus pathologies.
Materials And Methods: This retrospective study is based on the analysis of Cone-Beam Computed Tomography (CBCT) data from 510 sinuses of 255 patients. The visibility of the PSAA vascular canal, artery diameters, vertical distance between the alveolar crest and the artery, and the distance to the sinus floor were measured in coronal sections.
Free jejunal transplantation in a patient with short neck, cervical spondylosis, and vascular calcification: A case report.

Total pharyngo-laryngo-esophagectomy (TPLE) with free jejunal transplantation (FJT) is the standard reconstructive procedure for hypopharyngeal cancer, typically utilizing the superior thyroid artery as the recipient vessel. However, patient-specific anatomical variations and comorbidities can significantly complicate this surgery. We present a unique case of a 68-year-old male with hypopharyngeal cancer who exhibited multiple challenges, including short stature (126 cm), low weight (35 kg), cervical spondylosis, and a history of vertebroplasty, highlighting the complexities inherent in such reconstructions.

Bilateral vertebral artery dissections account for only 8% of all vertebral artery dissections and cause just 2% of all ischemic strokes. They can occur spontaneously, even without any triggering factor. Classical clinical findings, such as headache or neck pain, may be absent, particularly in the context of a stroke.

Indirect bypass using autologous tissue is effective in Moyamoya disease, especially among pediatric patients. This study aimed to evaluate the effectiveness of indirect bypass using DuraGen (absorbable artificial dura mater composed of collagen matrix), as a substitute for autologous tissue in a rat model of chronic cerebral hypoperfusion. Male Wistar rats were subjected to bilateral internal carotid artery occlusion and divided into three groups: a control group without bypass surgery, a group wherein indirect bypass was performed using the temporalis muscle (encephalo-myo-synangiosis [EMS] group), and a group wherein DuraGen was used (Dura group).
