Although the incidence of injury to the upper extremity screened with angiography as a result of proximity penetrating trauma is similar to that of the lower extremity, intervention rates seem to be higher. However, studies evaluating the incidence of injury as a result of proximity penetrating trauma have primarily focused on the lower extremity. This study shows the incidence and clinical significance of vascular injury as a result of proximity trauma to the upper extremity in a large cohort of patients screened with color-flow duplex. ⋯ Although color-flow duplex is an inexpensive and noninvasive means of detecting injuries as a result of proximity penetrating trauma, screening upper extremity wounds is unlikely to detect clinically significant arterial injuries in need of therapeutic intervention. Venous injuries in the form of deep venous thromboses were detected in only 1.4% of patients. These findings suggest that screening for proximity penetrating trauma of the upper extremity is unlikely to detect injuries at a rate that would prove cost-effective on formal decision analysis.

The documented risks of preoperative coronary revascularization prior to vascular surgery have led to a marked reduction in the role of percutaneous coronary intervention (PCI) during preoperative risk stratification. However, many patients with peripheral arterial disease are first identified immediately after a PCI for an acute coronary syndrome. We sought to determine the risks associated with these patients who then go on to have a peripheral arterial intervention (open operation or endovascular procedure). We hypothesized that there was no difference in outcomes in patients whose medical condition required PCI with coronary stent placement prior to a vascular operation compared with a control cohort of nonstented patients who underwent a vascular operation alone. We report the vascular operative outcomes in a contemporary cohort of vascular patients who had PCI with coronary stent placement for an acute event. ⋯ Patients who underwent PCI with coronary stent and then went on to require a vascular procedure had significantly more cardiovascular (CV) risk factors and were more likely to have an endovascular procedure than those patients without preoperative PCI. When controlling for CV risk factors and procedure type, there was no significant difference in death, MI, MACE, or bleeding complications between the groups.

True aneurysms and pseudoaneurysms of the visceral arteries are uncommon. Visceral artery aneurysms (VAAs) represent 0.1-0.2% of all vascular aneurysms and were also found in 0.1% of autopsies. VAAs most commonly affect the splenic (60%), hepatic (20%), and superior mesenteric (9%) arteries. ⋯ A 30-year-old man arrived at our trauma hospital and was found to have a traumatic pseudoaneurysm of the superior mesenteric artery (SMA) after a motor vehicle collision. To date, only 10 visceral arterial pseudoaneurysms have been reported in the literature. We present an 11th case of a pseudoaneurysm involving the SMA after blunt abdominal trauma.
