title: Endovascular interventions for descending thoracic aortic aneurysms: The pivotal role of the clinical nurse in postoperative care.
abstract: Descending thoracic aortic aneurysms (dTAA) comprise 40% of all aneurysms arising from the thoracic aorta. Because rupture of thoracic aneurysms is associated with a 94% mortality rate, timely detection, surveillance and treatment is imperative. Endovascular stent-graft repair of thoracic aneurysms was first performed in 1992 and has become an accepted treatment option for this condition in select candidates. There is an abundance of information for the care of patients after open surgical repair of dTAA. However, still relatively few written guidelines exist in the nursing literature for postoperative care and complications associated with endovascular stent-graft repair. The prevalence of aortic endografting, however, now makes it necessary for nurses to have a solid knowledge base in the operative procedure, complications and postoperative care for this patient population. Ideal candidates for aortic endografting undergo CTA or MRI preoperatively and fit a set of strict anatomic criteria to ensure proper delivery and fixation of the device. The early postoperative care focuses on minimizing pulmonary complications, paraplegia, renal failure and embolic complications such as stroke and limb ischemia through skilled nursing assessment and interventions. Late complications such as stent-graft migration, kinking, stent fracture and endoleak are often without symptoms, making it necessary for patients to be educated about these potential complications and to be encouraged to comply with lifelong follow up. This overview provides a sound cognitive framework for nurses practicing in a vascular surgery milieu.
