Open repair of a -associated abdominal aortic endovascular stent graft infection with a cryopreserved allograft using visceral artery pump perfusion.

the causative organism of Q fever, has been increasingly reported to be associated with infections of abdominal aortic aneurysms and endovascular stent grafts. We have added to the current literature by presenting a case of the surgical management of chronic Q fever that had infected a prior aortic endovascular stent graft placed for a contained rupture of an infrarenal aortic aneurysm in a 68-year-old woman. We presented our case of the surgical management of the excision and explantation of the infected aorta and stent graft, with reconstruction of the aorta using a cryopreserved aortic graft and visceral artery pump perfusion.

Aortoiliac Endarterectomy: A Useful Tool in Modern Vascular Practice.

Aortoiliac endarterectomy was the standard treatment for aortoiliac occlusive disease before the availability of prosthetic graft material for aortobifemoral bypass, although the number of patients appropriate for this repair continues to diminish in the endovascular era. Patients with focal aortoiliac disease are often treated with bilateral "kissing" iliac stents through an endovascular approach. However, in patients with eccentric plaque morphology or smaller caliber vessels, the risk of distal embolization and vessel rupture is not insignificant.

Endovascular Abdominal Aortic Aneurysm Repair: Does Anesthesia Type Matter?

Background: Given the various types of anesthesia used for endovascular abdominal aortic aneurysm repair (EVAR), we sought to determine the effect of anesthesia type in the outcomes of elective EVAR in a large multiinstitutional healthcare maintenance organization.

Methods: A retrospective chart review was conducted on all elective EVAR conducted from August 2010 to August 2017 in 14 regional hospitals of Kaiser Permanente Southern California. Patients undergoing emergent, nonelective abdominal aortic aneurysm repairs, thoracoabdominal aneurysm repair, requiring conversion to open surgery or general anesthesia were excluded from the study.

Effect of Endovascular Interventions on General Surgery Trainee Operative Experience; a Comparison of Case Log Reports.

Background: Vascular surgery fellowship training has evolved with the widespread adoption of endovascular interventions. The purpose of this study is to examine how general surgery trainee exposure to vascular surgery has changed over time.

Methods: Review of the Accreditation Council for Graduate Medical Education national case log reports for graduating Vascular Surgery Fellows (VF), and general surgery residents (GSR) from 2001 to 2012 was performed.

Intraprocedural and postprocedural perigraft arterial sac embolization (PASE) for endoleak treatment.

Intervention may be necessary in up to one-third of patients with endoleaks after endovascular aortic aneurysm repair (EVAR). Perigraft arterial sac embolization (PASE) to induce aneurysm thrombosis was performed by intrasac injection of thrombin and gelfoam slurry. Thirteen patients were treated with PASE since 2006.

A prospective study of carbon dioxide digital subtraction versus standard contrast arteriography in the detection of endoleaks in endovascular abdominal aortic aneurysm repairs.

Background: The objective of this study is to compare intraoperative endoleak detection by carbon dioxide digital subtraction angiography (CO(2)-DSA) during endovascular aortic aneurysm repair (EVAR) with standard iodinated contrast angiography (ICA).

Methods: Between 2006 and 2010, 76 patients with abdominal aortic aneurysms undergoing EVAR were enrolled in a prospective study. After EVAR, both an ICA and CO(2)-DSA completion study were performed.

Safety of carbon dioxide digital subtraction angiography.

Objective: Reports of fatality following carbon dioxide digital subtraction angiography (CO2-DSA) have raised concerns regarding its safety. This study reviews the safety of CO2-DSA.

Design: Single-institution retrospective review.

Antibiotic-impregnated grafts for aortic reconstruction.

An infected aorta, or aortic graft, is a challenge to manage. Extra-anatomical bypass followed by resection of the infected aorta has been considered standard practice. Outcomes are far from ideal and anatomical constraints make this impossible at the visceral and thoracic aorta.

Thrombin use in surgery: an evidence-based review of its clinical use.

When surgical ligation of bleeding fails, or is not possible, surgeons rely on a number of hemostatic aids, including thrombin. This review discusses the history, pharmacology and clinical application of thrombin as a surgical hemostat. The initial thrombin was bovine in origin, but its use has been complicated by the formation of antibodies that cross-react with human coagulation factors.

Clinical use of topical thrombin as a surgical hemostat.

When surgical ligation of bleeding fails, or is not possible, surgeons rely on a number of hemostatic aids, including thrombin. This review discusses the history, pharmacology and clinical application of thrombin as a surgical hemostat. The initial thrombin was bovine in origin, but its use has been complicated by the formation of antibodies that cross react with human coagulation factors.

Use of standardized, quantitative digital photography in a multicenter Web-based study.

Objective: We developed a Web-based, blinded, prospective, randomized, multicenter trial, using standardized digital photography to clinically evaluate hand burn depth and accurately determine wound area with digital planimetry.

Methods: Photos in each center were taken with identical digital cameras with standardized settings on a custom backdrop developed at Wake Forest University containing a gray, white, black, and centimeter scale. The images were downloaded, transferred via the Web, and stored on servers at the principal investigator's home institution.

Endovascular management of mycotic aortic aneurysms and associated aortoaerodigestive fistulas.

We evaluated the short- and intermediate-term results of endovascular aneurysm repair (EVAR) for mycotic aneurysms. We reviewed all patients undergoing EVAR for mycotic aneurysms at our institution. To be consistent with the existing literature, patients with associated aortoaerodigestive fistulas were included.

Endovascular management of hoarseness due to a thoracic aneurysm: case report and review of the literature.

Although uncommon, hoarseness can be a presenting symptom of a thoracic aneurysm. We present a case of a 67-year-old man with hoarseness, subsequently found to have left vocal paralysis. On workup, a computed tomography scan demonstrated a saccular thoracic aneurysm compressing the recurrent laryngeal nerve at the aortopulmonary window.

A comparison of recombinant thrombin to bovine thrombin as a hemostatic ancillary in patients undergoing peripheral arterial bypass and arteriovenous graft procedures.

Objectives: Recombinant thrombin (rThrombin) is a potential hemostatic alternative to bovine and human plasma-derived thrombin. This report examines the clinical results for the vascular surgery subgroup of patients enrolled in a larger double-blind, randomized, multicenter trial, which evaluated the comparative safety and efficacy of rThrombin and bovine plasma-derived thrombin (bThrombin) when used as adjuncts to surgical hemostasis.

Methods: Data from the 164 vascular patients who underwent either a peripheral arterial bypass (PAB) or arteriovenous graft (AV) procedure are included in this analysis.

Use of thrombolytics in vascular and endovascular surgery.

Until recently, acute arterial or venous thromboses were routinely managed with surgical intervention. With the development of effective thrombolytic pharmacologic agents and improved modes of delivery of these agents to the target site, surgery is no longer the only option. Greater understanding and knowledge about the finely orchestrated, counterbalanced processes of coagulation and fibrinolysis/thrombolysis have enabled development of agents and strategies for pharmacologic restoration of vascular patency while reducing or eliminating the need for surgery.
