Diagnosis and therapy of osteoporosis in geriatric trauma patients: an update.

Demographic changes confront clinicians with an increasing number of orthogeriatric patients. These patients present with comorbidities, which force their surgeons to take into consideration their medical condition. A major risk factor for fractures in orthogeriatric patients is osteoporosis in combination with frailty.

A prospective study of growth and rupture risk of small-to-moderate size ascending aortic aneurysms.

Objective: The natural history of small-to-moderate size ascending aortic aneurysms is poorly understood. To follow these patients better, we have developed a method to objectively and reproducibly measure ascending aortic volume on the basis of gated contrast computed tomography scans.

Methods: From 2009 to 2011, 507 patients were referred for management of ascending aortic aneurysms.

Imaging of vascular remodeling after simulated thoracoabdominal aneurysm repair.

Objective: A better understanding of the response of the spinal cord blood supply to segmental artery (SA) sacrifice should help minimize the risk of paraplegia after both open and endovascular repair of thoracoabdominal aortic (TAA) aneurysms.

Methods: Twelve female juvenile Yorkshire pigs were randomized into 3 groups and perfused with a barium-latex solution. Pigs in group 1 (control) had infusion without previous intervention.

Open repair of descending and thoracoabdominal aortic aneurysms and dissections in patients aged younger than 60 years: superior to endovascular repair?

Background: The best option for repair of descending thoracic and thoracoabdominal aortic aneurysms (TAAA)-whether open operation or stent grafting-is increasingly a subject of controversy. We examined the results of open surgical repair in patients aged 60 years or younger to assess the value of conventional repair in younger patients.

Methods: From October 2002 to October 2010, 107 of 294 TAAA operations were in patients (75 men [70%]) aged a mean of 48 ± 9 years.

Frequency of reoperations in patients with Marfan syndrome.

Background: We undertook a retrospective study of the pattern of reoperations in surgical patients with Marfan disease.

Methods: Between 1985 and 2008, 83 Marfan patients (60 males, 23 females) underwent 155 aortic operations in our institution. Twenty-eight patients had acute dissection (22 type A, 6 type B), and two had aortic rupture.
