Catheter-associated upper extremity deep venous thrombosis (CAUEDVT) is well known; however, resolution rates and factors affecting resolution of CAUEDVT are not well characterized. This study determined resolution rates and factors associated with resolution of CAUEDVT. ⋯ More than half of CAUEDVT resolve

To evaluate the cost-effectiveness of endovascular repair (EVAR) for small abdominal aortic aneurysms (AAA). ⋯ This analysis demonstrated that early EVAR for AAAs <5.5 cm is not likely to be cost-effective compared with elective repair at 5.5 cm. However, EVAR for small AAAs may become cost-effective when differences in quality of life and mortality are considered.

Symptomatic peripheral arterial disease (PAD) results in significant gait impairment. In an attempt to fully delineate and quantify these gait alterations, we analyzed joint kinematics, torques (rotational forces), and powers (rotational forces times angular velocity) in patients with PAD with unilateral claudication for both the affected and nonaffected legs. ⋯ Patients with PAD with unilateral claudication demonstrate significant gait impairments in both limbs that are present even before they experience any claudication symptoms. Overall, our data demonstrate significantly reduced ankle plantar flexion torque and power during late stance with reduced knee power during early and mid stance for the affected limb. Further studies are needed to determine if these findings are dependent on the location and the severity of lower extremity ischemia and whether the changes in the nonaffected limb are the result of underlying PAD or compensatory changes from the affected limb dysfunction.

Our institution treats about 30 patients per year with ruptured abdominal aortic aneurysms (rAAA). Between 2002 and 2007, our 30-day mortality averaged 58%. In July 2007, we implemented an algorithm to promote endovascular aneurysm repair (EVAR) when feasible. This report describes the outcome with this approach. ⋯ Use of an algorithm favoring endovascular repair resulted in a highly significant reduction in rAAA mortality in our urban hospital. Thirty-day mortality for open repair was no different between pre- and post-protocol eras. With modern techniques of resuscitation and surgical management, a majority of patients presenting with rAAA can survive.

The use of a carotid shunt is a well-accepted method for the prevention of cerebral ischemia during carotid surgery. Although carotid surgeons are familiar with the risks associated with shunt use, few reports have been published detailing the nature, incidence, or severity of shunt-related complications. ⋯ Burlington, Mass) shunt balloon inflation. To our knowledge, this complication of shunting during carotid endarterectomy has not been previously described.
