This prospective, nonrandomized clinical study indicates that eversion CEA is an effective surgical option comparable to conventional CEA with either primary arteriotomy closure or carotid patch angioplasty. No differences were found between eversion CEA and these more widely accepted CEA closure techniques with respect to operative morbidity and mortality. These data indicate, however, that eversion CEA has a lower restenosis rate than conventional CEA closure techniques and thus superior long-term durability.
Women with AAAs are older and have a higher frequency of cardiovascular risk factors than men. Women rupture AAAs with a greater frequency than men at all size intervals and have a fourfold increased frequency of rupture at <5.5 cm. No differences in surgical mortality between women and men were found. Current practice guidelines for elective AAA operative intervention should be reconsidered and stratified by gender.
Blunt subclavian artery trauma is an uncommon but challenging surgical problem. The purpose of this study was to retrospectively review the management of blunt subclavian artery injuries treated by the Trauma and Vascular Surgery Services at the East Tennessee State University-affiliated hospitals between 1992 and 1998. Six patients with seven blunt subclavian artery injuries were identified. Physical signs indicating blunt subclavian artery injury were pain or contusion around the shoulder joint; fractures of the clavicle, scapula, or ribs; periclavicular hematomas; and ipsilateral pulse or neurologic deficits. Seven subclavian artery injuries were treated-two arterial transections, two pseudoaneurysms, and three intimal dissections. Associated injuries included four clavicle fractures, one humerus fracture, one combined rib and scapular fractures, and two pneumothoraxes. Vascular surgical treatment included three primary arterial repairs, two saphenous vein interposition grafts, and one polytetrafluoroethylene (PTFE) graft. One patient was treated nonoperatively with anticoagulation. No deaths occurred. Morbidity occurred in two patients with chronic upper extremity neuropathy producing prolonged disability from pain and weakness; one patient had reflex sympathetic dystrophy, and the other had a brachial plexus injury. In conclusion, blunt subclavian artery trauma can be successfully managed with early use of arteriography and prompt surgical correction by a variety of vascular techniques. Vascular morbidity is usually low, but long-term disability because of chronic neuropathy may result from associated brachial plexus nerve injury despite a successful arterial repair.
Although a small number of secondary interventions were needed after EVAR with the Endologix Powerlink or AFX endografts, most were undertaken for late main-body component uncoupling and type IIIa endoleak, which can occur after sideways displacement of the endograft in large and angulated AAAs. Patients treated before 2013 under the old instructions for use should be evaluated for signs of impending component separation and monitored annually, noting that expected indicators of endograft failure, such as increasing AAA diameter and endoleak, may be absent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
