Researchers at the University of Chicago have published a report on extracranial vertebral artery injuries. The vertebral arteries travel through the cervical spine and contribute to posterior cerebral circulation. Injuries to the cervical spine can pose a risk to the vertebral artery, potentially leading to posterior circulation stroke. Surgeons must have a thorough understanding of the anatomy of the vertebral artery to avoid injury during cervical spine surgeries. Preoperative assessment and advanced imaging studies are necessary to prevent iatrogenic injury. Treatment options for vertebral artery injuries include tamponade, ligation, repair, or endovascular procedures. [Extracted from the article]

A study conducted at the University of North Carolina Chapel Hill explores the use of endovascular and open surgical approaches in treating patients with complex vascular disease. The research highlights the potential for traditional open surgical techniques to facilitate endovascular procedures in certain situations. The study specifically focuses on the use of endovascular procedures to assist with difficult open surgical situations such as iliofemoral bypass and aortic arch debranching. The research has been peer-reviewed and is available in The Journal of Cardiovascular Surgery. [Extracted from the article]

Researchers from the Nemours Cardiac Center in Wilmington, Delaware have conducted a study on the developmental significance of aberrant subclavian artery (ASCA) in interrupted aortic arch (IAA) with aortic/subaortic obstruction. The study focused on newborns with prenatally diagnosed isolated IAA and found that the presence of ASCA was associated with larger patent ductus arteriosus (PDACSA), suggesting an adaptive enlargement of the ductus arteriosus and ASCA in response to reduced antegrade flow across small aortic valve opening (AVOCSA), which may be augmenting cerebral blood flow. The research concluded that preservation of cerebral blood flow may be another important determinant affecting embryonic cardiovascular development. [Extracted from the article]

A recent study conducted at the Mayo Clinic in Rochester, Minnesota examined the outcomes of surgical repair for aberrant subclavian arteries (ASCA) in adults. The study found that symptoms, imaging characteristics, and surgical outcomes for ASCA in adults are not well defined. The researchers conducted a retrospective review of adults who underwent surgical repair for ASCA and descending aorta origin/Kommerell diverticulum (KD) between 2002 and 2021. The study concluded that surgical repair effectively relieves symptoms, with low rates of reintervention, and should be performed in patients meeting size criteria or experiencing significant dysphagia or shortness of breath symptoms.

A recent study conducted at Henry Ford Hospital in Detroit, Michigan, analyzed patients with acute type B aortic dissection (aTBAD) who underwent thoracic endovascular aortic repair (TEVAR) with left subclavian artery (LSA) coverage. The study aimed to determine whether LSA revascularization reduced the risk of neurologic complications. The results showed that patients who had their LSA revascularized had a significantly lower incidence of neurological injury, including spinal cord ischemia and/or stroke. However, there was no significant difference in mortality rates between patients who had LSA revascularization and those who did not. [Extracted from the article]
