Endovascular stenting of thoracic aortic aneurysm

Postoperative ICU management of vascular surgery patients

Critical care management of vascular surgical patients poses significant challenges owing to patients' comorbidities and the magnitude of the surgical procedures. The primary goals of the anesthesiologist and intensivist are reestablishing preoperative homeostasis, optimizing hemodynamics until return of normal organ function, and managing postoperative complications promptly and effectively. Postoperative critical care management demands a detailed knowledge of the various vascular surgical procedures and the potential postoperative complications. In this review, the authors describe the postoperative complications related to the major specific vascular surgical procedures and their perioperative management.

Thoracic endovascular aortic repair: update on indications and guidelines

Thoracic endovascular aortic repair (TEVAR) has revolutionized thoracic aortic surgery and has increased the options available to the aortic specialist in treating thoracic aortic disease. TEVAR is less invasive, and is associated with a decrease in perioperative morbidity and mortality when compared with open surgical repair. The dramatic expansion of TEVAR activity has necessitated a better definition for the indications, contraindications, and limitations of this new technology. Ideally TEVAR should be performed in specialized aortic centers providing a full range of diagnostic and treatment options, using a multidisciplinary team approach.

Neurological complications of thoracic endovascular aortic repair

Thoracic endovascular aortic repair (TEVAR) has decreased the morbidity and mortality associated with open surgical repair of descending thoracic aortic diseases, but important complications unique to the procedure remain. Spinal cord ischemia and infarction is a recognized complication caused by endovascular coverage or injury to spinal cord collateral vessels. Stroke is a consequence of thromboembolism or coverage of aortic arch branch vessels with insufficient collateral circulation. Understanding the risk factors and the pathophysiology of neurological complications of TEVAR are important for the successful anesthetic and surgical management and treatment of patients undergoing endovascular procedures involving the thoracic aorta.

The anesthetic management of cardiovascular trauma

PURPOSE OF REVIEW

Although little new has been specifically written in recent years regarding the anesthesia management of cardiovascular trauma, two specific areas have seen recent interest and progress, namely the endovascular management of blunt thoracic aortic trauma and commotio cordis, or sudden death following blunt precordial injury.

RECENT FINDINGS

Endovascular repair of thoracic aortic injury has been shown in multiple studies to have short to medium-term mortality and morbidity advantages over repair via thoracotomy. However, long-term (many years) outcome and the expenses required for long-term follow-up of endovascular repairs remain unknown. The risk of commotio cordis during sports activities has become more known to the general population. Recent studies have indicated a very specific limited time during the upstroke of the T-wave to be the critical time for injury, but specific channel involvement is unclear.

SUMMARY

Although transesophageal echocardiography diagnosis of aortic trauma is very sensitive and specific, in general, the lack of immediate availability at all times of skilled echocardiographers and the immediate availability of spiral computed tomography scanners in trauma centers limits the use of transesophageal echocardiography as a first-line diagnostic tool. Endovascular repair of traumatic aortic injury is becoming routine. Commotio cordis is being increasingly recognized as a cause of acute post-traumatic sudden death.
