The Annals of thoracic surgery

Loeys-Dietz syndrome (LDS) is a recently recognized connective tissue disorder (CTD) caused by mutations in transforming growth factor-beta receptor (TGFBR)1 and TGFBR2. Surgical outcomes of aortic repair in patients with LDS are poorly known. ⋯ Surgical outcomes for patients with LDS were satisfactory. Once aortic dissection occurred, the aorta expanded rapidly, requiring further operations. Therefore, early surgical intervention may improve prognosis by preventing a fatal aortic event.

Lower extremity ischemia is an important source of morbidity with femoral venoarterial extracorporeal membrane oxygenation support. We describe our experience with the use of a side-arm graft sewn to the femoral artery that facilitates adequate extracorporeal membrane oxygenation flow while preventing lower extremity ischemia.

Arch reconstruction is a key part of the Norwood operation for hypoplastic left heart syndrome and is related to late morbidity. Since 2003, our surgical technique has been standardized to a right ventricle to pulmonary artery conduit, arch reconstruction with homograft patch, and Damus-Kaye-Stansel anastomosis onto homograft patch, with partial or complete resection of any coarctation ridge. We studied the impact of the surgical approach on arch reinterventions and outcome. ⋯ Our standard technique for the Norwood operation has good results but further intervention for recoarctation is common. Size of ascending aorta and incomplete resection of coarctation tissue were risk factors for recoarctation. Complete resection of coarctation tissue may reduce the incidence of recoarctation. A small ascending aorta may predict late arch problems.

The RIFLE criteria (risk, injury, failure, loss, and end-stage kidney disease) have been used to assess acute kidney injury (AKI) in various populations of critically ill children. There are limited reports of AKI using RIFLE criteria in large pediatric populations undergoing congenital heart disease surgery. ⋯ Incidence of AKI based on RIFLE criteria in patients undergoing congenital heart disease surgery is higher than previously reported. Risk factors include age 1 month or younger and use of cardiopulmonary bypass. Acute kidney injury is associated with longer lengths of stay.

Penetrating trauma has increased in developed and urban environments. Pulmonary artery injury is rare, but can be associated with significant morbidity. ⋯ The patient had active great vessel bleeding and required extensive surgical intervention. Clinicians should have a high index of suspicion for life-threatening thoracic injuries following a stab injury to the chest, despite initial clinical stability or negative baseline radiological findings.
