VASCULAR MEDICINE. Peripheral arterial ischemic events in cancer patients

Saurabh Sanon, Daniel J Lenihan and Elie Mouhayar

Thromboembolic complications are the second leading cause of death in cancer patients. In contrast to the large body of literature on venous thromboembolism (VTE), relatively few reports have focused on the pathogenesis, incidence, management and outcomes of arterial thromboembolic events in patients with malignancy. The purpose of this article is to review the current literature on the etiology, mechanisms, and prognosis of arterial thromboembolic events in cancer patients and outline appropriate screening and management guidelines that may help lower the rates of morbidity and mortality related to these events.

JOURNAL OF VASCULAR SURGERY. Changes in thrombin generation, fibrinolysis, platelet and endothelial cell activity, and inflammation following endovascular abdominal aortic aneurysm repair

Mohamed F. Abdelhamid, MS, MRCSE, Robert S. M. Davies, MRCS, Donald J. Adam, MD, FRCSEd, Rajiv K. Vohra, MD, FRCS , Andrew W. Bradbury, BS, MBA, MD, FRCSE, Birmingham, United Kingdom

Background: Abdominal aortic aneurysm (AAA) is a chronic inflammatory condition associated with a prothrombotic, hypofibrinolytic diathesis that may increase the risk of cardiovascular events. The effect of endovascular aneurysm repair (EVAR) on this prothrombotic diathesis is not fully understood, especially over the medium and long term. A better understanding of these postintervention changes may improve the risk of cardiovascular complications in the long term. The purpose of this study was to examine thrombin generation, fibrinolysis, platelet and endothelial activation, and the inflammatory response during the 12 months following EVAR.

JOURNAL OF MEDICAL CASE REPORT. Simultaneous endovascular repair of an iatrogenic carotid-jugular fistula and a large iliocaval fistula presenting with multiorgan failure: a case report

Yuigi Yuminaga, Walid Mohabbat, Tam Nguyen, Andrew Michael Thompson and Charles Marshall Fisher

Iliocaval fistulas can complicate an iliac artery aneurysm. The clinical presentation is classically a triad of hypotension, a pulsatile mass and heart failure. In this instance, following presentation with multiorgan failure, management included the immediate use of an endovascular stent graft on discovery of the fistula. Yuminaga et al.

JOURNAL OF VASCULAR SURGERY. Percutaneous transluminal angioplasty for treatment of critical hand ischemia with a novel endovascular approach: “The radial to ulnar artery loop technique”

Roberto Gandini, MD, Georgios Angelopoulos, MD, Valerio Da Ros, MD, and Giovanni Simonetti, MD, Rome, Italy

A 44-year-old patient with type I diabetes with critical upper limb ischemia of the left hand was referred to our department with ischemic tissue loss and rest pain. After unsuccessful use of the endovascular antegrade approach, retrograde revascularization with percutaneous transluminal angioplasty (PTA) of the ulnar artery and the Palmar arch through the radial artery was successfully performed (the radial to ulnar artery loop technique). Relief of the patient’s symptoms was immediate and ischemic lesions were healed at 6-month follow-up. This technique, which has been used for the first time in critical upper limb ischemia, may significantly increase the success rate of percutaneous angioplasty, especially when antegrade recanalization fails.

JOURNAL OF VASCULAR SURGERY. Hybrid treatment of an ascending aortic pseudoaneurysm following multiple sternotomies

Vito Giovanni Ruggieri, MD, Romain Malezieux, MD, Najeebullah Bina, MD, and Jean-Pierre Favre, MD, PhD, St. Etienne, France

Ascending aortic pseudoaneurysm following prior cardiac or aortic surgery is a rare entity that requires reoperation. Surgical repair is a complex procedure associated with high operative mortality. We report the case of a 76-year-old male patient with an ascending aortic pseudoaneurysm developing from distal anastomosis of a Dacron aorto-aortic prosthesis. This high-risk patient had previously undergone multiple cardiovascular operations and was treated by performing an extra-anatomic bypass between the descending thoracic aorta and supra-aortic vessels, followed by endovascular stent graft placement, avoiding median re-sternotomy.

JOURNAL OF VASCULAR SURGERY. A case of external iliac arteriovenous fistula and high-output cardiac failure after endovenous laser treatment of great saphenous vein

Scott J. Ziporin, MD, Catherine K. Ifune, MD, Malcolm P. MacConmara, MD, Patrick J. Geraghty, MD, and Eric T. Choi, MD, St Louis, Mo

Valvular incompetence in the great saphenous vein (GSV) is the most common cause of superficial venous insufficiency and symptomatic varicose vein development. Recently, less invasive modalities such as foam sclerotherapy, radiofrequency ablation (RFA), and endovenous laser treatment (EVLT) have gained popularity in the treatment of saphenofemoral junction and saphenous truncal incompetence over the traditional approach of surgical ligation and stripping. Here, we present the case of a 32-year-old woman who underwent EVLT and was diagnosed subsequently with ipsilateral external iliac arteriovenous (AV) fistula and high-output cardiac failure. She was stabilized medically and treated surgically with a covered stent placed in the external iliac artery with complete resolution of the fistula and cardiac failure. We reviewed the literature and discuss the complications of AV fistulae after EVLT. JOURNAL OF VASCULAR SURGERY Volume 51, Number 3 J Vasc Surg 2010;51:715-9.

JOURNAL OF VASCULAR SURGERY. The challenge of associated intramural hematoma with endovascular repair for penetrating ulcers of the descending thoracic aorta

Himanshu J. Patel, MD, David M. Williams, MD, Gilbert R. Upchurch Jr, MD, Narasimham L. Dasika, MD, and G. Michael Deeb, MD, Ann Arbor, Mich

The presence of penetrating aortic ulcers (PAUs) of the descending thoracic aorta has been associated with a poor long-term prognosis. Although early results have suggested acceptable outcomes for thoracic endovascular aortic repair (TEVAR) for PAU, few studies have described the late outcomes of this approach.

JOURNAL OF VASCULAR SURGERY. Treatment of a pelvic arteriovenous malformation by stent graft placement combined with sclerotherapy

Sun Young Choi, MD, Young Soo Do, MD, Do Yun Lee, MD, Kwang-Hun Lee, MD, and Jong Yun Won, MD, Seoul, Republic of Korea

We present a 64-year-old woman with left leg swelling for 1 year. Computed tomography imaging showed a large pelvic arteriovenous malformation that consisted of multiple fine shunts between the left internal iliac artery and the long segment of the left external iliac vein. A stent graft was inserted within the left external iliac vein to occlude the arteriovenous shunts with consecutive transarterial sclerotherapy using absolute ethanol. This resulted in complete resolution of the pelvic arteriovenous malformation. To our knowledge, this is the first reported case of stent graft insertion within a large vein for treating arteriovenous malformation. JOURNAL OF VASCULAR SURGERY Volume 51, Number 4.

JOURNAL OF VASCULAR SURGERY. Endovascular repair of popliteal aneurysms

Claudio S. Cina, MD, FRCSC, MSc (HRM), Toronto, Ontario, Canada

Endovascular repair is an established modality of treatment for abdominal aortic aneurysms. It is therefore reasonable to expect its application to other less common aneurysmal conditions, including isolated iliac and popliteal artery aneurysms (PAA). There are, however, essential differences between aortic aneurysms and peripheral aneurysms: smaller arterial caliber, mobility of the arterial segment, associated occlusive disease, and devices that have not been specifically designed for peripheral applications. Due to these differences, results obtained in abdominal aortic aneurysms cannot be extrapolated to peripheral aneurysms. The attraction of the endovascular repair for PAA is its minimally invasive nature. The literature, however, provides only case reports, case series and small cohorts, and one small randomized, controlled trial. A cumulative summary of these studies provides the clinician with information upon which to base the choice of treatment on a specific patient. Endovascular repair for PAA with suitable anatomy and good run-off can be considered safe, and medium term results appear comparable with those of open repair.

VASCULAR AND ENDOVASCULAR SURGERY. Open Repair and Endovascular Covered Stent Placement in the Management of Bilateral Axillary Artery Aneurysms

Douglas A. Troutman, DO, Chittur R. Mohan, MD, Farouq A. Samhouri, MD, and Richard L. Sohn, MD Abstract

A 72-year-old male with chronic obstructive pulmonary disease and hyperlipidemia presented with acute right upper limb ischemia. Arterial occlusion was found to be secondary to a thrombosed axillary artery aneurysm. An open repair was performed with a polytetrafluoroethylene (PTFE) graft. On further workup, the patient was found to have an asymptomatic axillary artery aneurysm on the left-hand side. Endovascular repair with a covered stent was chosen to treat this aneurysm.
