The Annals of thoracic surgery

Blunt thoracic aortic injury (BTAI) and traumatic brain injury (TBI) are the leading causes of death after blunt trauma, and TBI is common among patients with BTAI. Although aspects of aortic management, such as repair timing and procedural anticoagulation therapy, may complicate TBI, the optimal management of these patients is undefined. ⋯ For patients with BTAI and TBI, early aortic intervention is associated with progressive TBI regardless of repair modality, as well as increased aortic morbidity and mortality. Patients not requiring emergent intervention can undergo delayed repair with full anticoagulation therapy.

The risk of clinically apparent, periprocedural stroke after thoracic endovascular aortic repair (TEVAR) due to dislodgement and embolization of aortic debris from intravascular manipulation of guidewires, catheters, and large-bore delivery systems ranges between 2% and 6% and has been associated with increased postoperative mortality. The rate of clinically silent cerebral ischemia is yet unknown, but may be even higher. ⋯ Thoracic endovascular aortic repair resulted in a high incidence of new foci of restricted diffusion on cerebral DW-MRI in a pattern suggestive of periprocedural embolization. Although multiple lesions per patients were found, these lesions were not associated with apparent neurologic deficits during the in-hospital period. Further developments in TEVAR should be directed toward reducing the risk of periprocedural cerebral embolization.

Survival after cardiac surgery in infancy requires adaptive responses from oxidative stress management and vascular regulation pathways. We tested the hypothesis that genetic variation in these pathways influences postoperative survival in nonsyndromic congenital heart disease children. ⋯ After cardiac surgery, infants who are homozygous for the high-risk alleles for both the VEGFA and SOD2 SNPs have an approximately 16-fold increased risk of death or heart transplant, suggesting that genetic variants are important modifiers of survival after surgery for congenital heart disease.

Our objective was to determine the incidence and optimal management of chylothorax after pulmonary resection with complete thoracic mediastinal lymph node dissection (MLND). ⋯ Chylothorax after pulmonary resection and MLND occurred in 1.4% of patients. Its incidence was higher in those with pathologic N2 disease and those who underwent robotic resection. Nonoperative therapy is almost always effective.

Case Reports
Birt-Hogg-Dubé syndrome in a patient presenting with familial spontaneous pneumothorax.
Birt-Hogg-Dubé (BHD) syndrome is a recently discovered autosomal-dominant disease caused by a mutation in the folliculin gene. We report a patient with familial spontaneous pneumothorax who was found to have BHD syndrome. Patients with a personal and family history of pneumothoraces and computed tomographic (CT) findings of multiple pulmonary cysts should alert the thoracic surgeon to this syndrome; additional evaluation and testing may be warranted.
