Common and uncommon CT findings in rupture and impending rupture of abdominal aortic aneurysms.

The rapid imaging evaluation and diagnosis of rupture and impending rupture of an abdominal aortic aneurysm (AAA) is imperative. This article describes the imaging findings of rupture, impending rupture, and other abdominal aortic abnormalities. It is important not to overlook AAA as the consequences can be life threatening.

Acute aortic syndrome: CT findings.

Acute aortic syndrome (AAS) is a constellation of potentially life-threatening acute aortic diseases. The spectrum includes penetrating atherosclerotic ulcer, intramural haematoma, dissection, and unstable thoracic aneurysm. AAS cannot be reliably diagnosed clinically and multidetector computed tomography (MDCT) has revolutionized the diagnosis and management of this group of conditions in the acute setting due to its availability, speed, and accuracy.

Penetrating atherosclerotic ulcer of the aorta: a continuing debate.

Aortic penetrating atherosclerotic ulcer (PAU) is a relatively common incidental finding on thoracic computed tomography (CT) examinations. This is likely to relate to the steady increase in the number of CT examinations performed and also due, in part, to the increasing age of the general population. There is as yet no consensus on the management of incidental PAUs in asymptomatic patients.

Patterns of renal angiomyolipoma regression post embolisation on medium- to long-term follow-up.

Objective: To assess the patterns of regression of renal angiomyolipoma (AML) post embolisation and report the outcomes related to the use of different embolic materials.

Methods: A retrospective review of all patients who underwent embolisation for renal AML at our institution between January 2004 and April 2012.

Results: 13 patients underwent 16 episodes of embolisation.

Replacement tunnelled dialysis catheters for haemodialysis access: Same site, new site, or exchange - a multivariate analysis and risk score.

Aim: To identify variables related to complications following tunnelled dialysis catheter (TDC) replacement and stratifying the risk to reduce morbidity in patients with end-stage renal disease.

Materials And Methods: One hundred and forty TDCs (Split Cath, medCOMP) were replaced in 140 patients over a 5 year period. Multiple variables were retrospectively collected and analysed to stratify the risk and to predict patients who were more likely to suffer from complications.

Renal artery stenosis: an innocent bystander or an independent predictor of worse outcome in patients with chronic heart failure? A magnetic resonance imaging study.

Aims: To investigate the prognostic impact of atherosclerotic renovascular disease in patients with chronic heart failure.

Methods And Results: Patients with heart failure due to left ventricular systolic dysfunction underwent cardiac magnetic resonance imaging and contrast-enhanced magnetic resonance angiography. Renal artery stenosis (RAS) was defined as a luminal narrowing >50%.

Primary infrarenal aortic stenting with or without iliac stenting for isolated and aortoiliac stenoses: single-centre experience with long-term follow-up.

Purpose: The purpose of this study was to evaluate the technical success, complications, long-term clinical outcome, and patency after primary infrarenal aortic stenting for aortic and aortoiliac stenosis. Between January 1999 and January 2006, 22 consecutive patients underwent endovascular treatment because of infrarenal aortic stenosis with and without common iliac stenosis (10 men; mean age 64 ± 14 years). Eleven (11 of 22) patients had an isolated aortic stenosis, whereas 11 of 22 had aortic stenosis that extended into the common iliac arteries (CIAs).

Long-term follow-up of treatment of pulmonary arteriovenous malformations with AMPLATZER Vascular Plug and AMPLATZER Vascular Plug II devices.

Purpose: To assess the feasibility, complications, and long-term success of embolization of pulmonary arteriovenous malformations (PAVMs) with the AMPLATZER Vascular Plug and AMPLATZER Vascular Plug II.

Materials And Methods: The study included 15 consecutive patients (19 embolization episodes) who had embolization of PAVMs between April 2004 and April 2009 with an AMPLATZER Vascular Plug or AMPLATZER Vascular Plug II. There were 4 men and 11 women, with a mean age of 56 years (range 24-74 years).

Atherosclerotic disease of the abdominal aorta and its branches: prognostic implications in patients with heart failure.

Aortic atherosclerosis reduces compliance in the systemic circulation and increases peripheral resistance, afterload and left ventricular wall stress. In patients with heart failure, these changes can impair left ventricular systolic function and energy efficiency, which could reduce exercise capacity. Though the interaction and the impact of aortic atherosclerosis on left ventricular function have been investigated, its prognostic implications in patients with heart failure are unclear.

Patient experience, pain, and quality of life after lower limb angioplasty: a multisite prospective cohort study.

Purpose: To explore the experience of patients undergoing endovascular lower limb angioplasty and evaluate the improvements in quality of life and disease-related symptoms after the procedure.

Methods: Patients completed a questionnaire before treatment and three questionnaires after the procedure (immediately after the procedure, and again 4 weeks and 3 months later). Anxiety, patient understanding, procedure-related pain, and disease-related pain were assessed by a visual analog score (VAS).

Staged coil embolisation for the management of persistent aneurysmal right subclavian artery.

A 70-year-old patient, who had previously undergone open surgical repair of an aneurysmal aberrant right subclavian artery (ARSA), presented with recurrent symptoms and reperfusion of the aneurysm at the site of proximal ligation. This was successfully treated by a staged endovascular procedure.

Endovascular management of bilateral superior intercostal artery aneurysms following late repair of coarctation of the aorta.

Endovascular management of massive bilateral superior intercostal artery aneurysms following late surgical repair of juxtaductal coarctation of the aorta is described in a 40-year-old male patient. Both aneurysms were successfully treated by coil embolisation without the need for further surgical intervention.

Three-year follow-up of fenestrated thoracoabdominal stent graft bridging an endovascular thoracic stent graft and a surgical abdominal aortic graft.

This case report describes repair of a type I endoleak at the distal landing zone of a thoracic aortic stent graft by endovascular placement of a thoracoabdominal fenestrated stent graft (Cook, Brisbane, Australia). The fenestrated stent graft was interposed between a previous abdominal aortic aneurysm (AAA) Gelsoft tube graft (Sulzer Vascutek Ltd, Inchinnan, United Kingdom) and two overlapping Zenith thoracic endografts (Cook Inc, Bloomington, Indiana). Placement was made more complex because the distal thoracic endograft had rotated into a horizontal position.

Clinical outcomes following endovascular treatment of the malfunctioning autologous dialysis fistula.

Background: There is limited long-term prospective data on the use of endovascular techniques and the use of thrombolysis in malfunctioning autologous haemodialysis fistulas.

Purpose: Prospective assessment of clinical outcomes following angioplasty with or without low-dose thrombolysis was undertaken in patients who presented with malfunctioning autologous haemodialysis fistulas.

Methods: Consecutive patients referred to our department over a 6-month period were included.

Iatrogenic arteriovenous fistula as a cause for leg ulcers: a case report.

An 80-year-old man presented with painful leg ulceration due to steal phenomenon from a groin arteriovenous fistula (AVF) 10 years following a coronary angiogram. The diagnosis of the AVF was confirmed by duplex examination of the groin vessels which demonstrated characteristic flow pattern in the femoral arterial and venous system. Angiography further confirmed the site of the fistulous communication and this was managed by a covered stent graft.

Long-term outcomes of low-dose catheter-directed thrombolytic therapy: a 5-year single-center experience.

Purpose: To determine immediate and long-term outcomes following catheter-directed intraarterial thrombolysis of occluded native arteries and infrainguinal vein grafts by using low-dose tissue-type plasminogen activator (tPA) in patients with lower limb ischemia.

Materials And Methods: One hundred eleven intraarterial thrombolysis procedures were performed in 96 patients during the 2-year study period. Patient records were available for retrospective review in 85 thrombolytic procedures performed in 74 (77%) of the 96 patients.

Carotid stump syndrome: pathophysiology and endovascular treatment options.

Carotid stump syndrome is one of the recognised causes of recurrent ipsilateral cerebrovascular events after occlusion of the internal carotid artery. It is believed that microemboli arising from the stump of the occluded internal carotid artery or the ipsilateral external carotid artery can pass into the middle cerebral artery circulation as a result of patent external carotid-internal carotid anastomotic channels. Different pathophysiologic causes of this syndrome and endovascular options for treatment are discussed.

Long term follow-up of transcatheter coil embolotherapy for major colonic haemorrhage.

Aim: Therapeutic angiography with embolization is fast becoming the preferred treatment modality for major bleeding in the lower gastrointestinal (LGI) tract. The aim of this study was to determine the long term outcome and complications of percutaneous coil embolization (PCE) and its efficacy as definitive therapy in patients with major LGI bleeding.

Methods: All patients presenting to our institution with a haemodynamically significant LGI tract bleed between 1995 and 2001 that were unresponsive to conservative measures were considered for emergency angiography and coil embolization where appropriate.

Magnetic resonance angiography: current status in the planning and follow-up of endovascular treatment in lower-limb arterial disease.

Magnetic resonance angiography (MRA) has become an established imaging modality in the management of lower-limb arterial disease, with emerging roles in treatment planning and follow-up. Contrast-enhanced MRA is now the most widely used technique with clinically acceptable results in the majority of patients. Difficulties in imaging and image interpretation are recognised in certain subgroups, including patients with critical limb ischaemia as well as patients with stents.

Inferior vena cava filter use in pregnancy: preliminary experience.

Thromboembolism is the most common direct cause of maternal mortality in the UK. Inferior vena cava (IVC) filter placement is indicated in conditions where recurrent thromboembolism occurs despite adequate anticoagulation or when anticoagulation is contraindicated. The safety of IVC filter use in pregnancy is uncertain, as there are limited data available.
