Carotid-Carotid Transposition for Zone 1 Thoracic Endovascular Aortic Repair

The Call for the "Interventional/Hybrid" Aortic Surgeon: Open, Endovascular, and Hybrid Therapies of the Aortic Arch

Aortic arch pathology is relatively rare but potentially highly fatal and associated with considerable comorbidity. Operative mortality and complication rates have improved over time but remain high. In response, aortic arch surgery is one of the most rapidly evolving areas of cardiac surgery in terms of surgical volume and improved outcomes. Moreover, there has been a surge in novel devices and techniques, many of which have been developed by or codeveloped with vascular surgeons and interventional radiologists. Nevertheless, the extent of arch surgery, the choice of nadir temperature, cannulation, and perfusion strategies, and the use of open, endovascular, or hybrid options vary according to country, centre, and surgeon. In this review article, we provide a technical overview of the surgical, total endovascular, and hybrid repair options for aortic arch pathology through historical developments and contemporary results. We highlight key information for surgeons, cardiologists, and trainees to understand the management of patients with aortic arch pathology. We conclude by discussing training paradigms, the role of aortic teams, and gaps in knowledge, arguing for the need for wire skills for the future "interventional aortic surgeon" and increased research into techniques and novel devices to continue improving outcomes for aortic arch surgery.

Uncorrected Preoperative Infection Causing the Death of a Patient with a Thoracic Aortic Aneurysm

Background

A thoracic aortic aneurysm (TAA) is a known condition seen in cardiovascular practice. A TAA rupture and postoperative infection may result in death. Preoperative infections leading to death are extremely rare.

Case Study

A 62-year-old Chinese female was admitted to The First Hospital of Hebei Medical University with a two-day history of abdominal pain. She was diagnosed with a TAA rupture and underwent immediate surgery. The preoperative urine analysis indicated that the positive bacteria and white blood cell count suggested a urinary tract bacterial infection. The patient was administered the empiric antibiotics, cefazolin; however, her blood pressure continued to drop during the perioperative period and she died of uncorrectable acidosis 8 h after the operation. On the second day after death, both the blood and urine cultures were positive for Pseudomonas aeruginosa.

Conclusion

Given that this patient with a TAA rupture died of uncorrected acidosis caused by preoperative infection, it is important to evoke the diagnosis in the context of TAA. Routine laboratory indicators are valuable factors for surgeons and physicians in assessing a patient's condition and improving their prognosis.
