Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly used diagnostic and therapeutic technique but it is not free of complications. Subcapsular hepatic haematoma is a rare but potentially fatal complication. A 71-years-old male patient resorted to the emergency department 36 hours after an uneventful ERCP presenting with severe abdominal pain and haemoglobin drop. Abdominal ultrasound and CT scan diagnosed a subcapsular hepatic haematoma. The patient was haemodynamically normal and was successfully treated with a conservative management...

OBJECTIVES: There is potential for high radiation exposure during neurointerventional procedures. Increasing regulatory requirements mandate dose monitoring of patients and staff, and justification of high levels of radiation exposure. This paper demonstrates the potential to use radiation dose-tracking software to establish local diagnostic reference levels. METHODS: Consecutive neurointerventional procedures, performed in a single institution within a one-year period, were retrospectively studied...

PURPOSE: Endovascular stents are widely used for the elective treatment of cerebral aneurysms. Acute stenting is performed in the management of dissections, pseudo-aneurysms, broad-based aneurysms or as a 'bail out' measure after coil migration. The purpose of this study is to review the safety of using stents in acute subarachnoid haemorrhage. METHODS: The stent registry of our institution was reviewed for procedures in patients with acute subarachnoid haemorrhage...

A 79-year-old man was admitted electively for investigation of weight loss. While he was an inpatient, he developed severe epigastric pain and an initial blood test revealed an acutely raised amylase (>2000) and deranged liver function tests. A contrast CT angiography showed a large haematoma adjacent to the duodenum, spreading in the retroperitoneal space, arising from a 2 cm bleeding pseudoaneurysm in the region of the gastroduodenal artery. Due to his underlying comorbidities, he was deemed unfit for surgical repair and he had coil embolisation with successful haemostasis...

Malignant soft tissue tumours are rare in infants. Specific radiologic features help differentiate benign from malignant musculoskeletal entities. We report a case of malignant soft tissue tumour with initial radiologic evaluation suggesting a benign entity, thus delaying diagnosis. The case was treated as a case of cystic hygroma, suggested by ultrasound and MRI with good initial response to bleomycin injection. Later, symptoms recurred with poor response to repeat therapy which led to review the diagnosis...

INTRODUCTION: Arteriovenous malformations (AVMs) are a type of vascular malformation characterised by an abnormal connection between arteries and veins, bypassing the capillary system. This absence of capillaries generates an elevated pressure (hyperdebit), in both the AVM and the venous drainage, increasing the risk of rupture. Management modalities are: observation, microsurgical clipping, endovascular treatment and radiosurgery. The former can be used alone or in the frame of a multidisciplinary approach...

Cholesterol crystals embolise when an aortic atherosclerotic lesion ruptures and cholesterol crystals are scattered and obstruct small peripheral arterioles. Risk factors include both iatrogenic factors such as intravascular catheterisation, and spontaneous factors for atherosclerosis such as aging, hypertension, dyslipidaemia, and smoking. We describe the case of an 83-year-old Japanese man who developed unilateral, superficial necrosis of the tongue as a result of spontaneous embolisation of cholesterol crystals...

A patient with a cystic artery pseudoaneurysm (CAP) presented to the emergency department with upper abdominal and back pain. The patient also had clinical signs of sepsis. CT revealed gallstones with acute suppurative cholecystitis with a gallbladder perforation. In addition, a CAP was also suspected and subsequently diagnosed on CT angiography. The pseudoaneurysm was treated with embolisation and a cholecystostomy was performed for the gallbladder perforation. Following her acute admission, the patient underwent an elective cholecystectomy and made a good recovery post surgery...

Saphenous vein grafts (SVGs), used during coronary artery bypass graft surgery for severe coronary artery disease, are prone to degeneration and occlusion, leading to poor long-term patency compared with arterial grafts. Interventions used to treat SVG disease are susceptible to high rates of periprocedural MI and no-reflow. To minimise complications seen with these interventions, proper stents, embolic protection devices (EPDs) and pharmacological selection are crucial. Regarding stent selection, evidence has demonstrated superiority of drug-eluting stents over bare-metal stents in SVG intervention...

Herbert G Kroon, Nicolas Mda Van Mieghem
Transcatheter aortic valve implantation (TAVI) is a less invasive aortic valve replacement technique and is indicated for patients with symptomatic severe aortic stenosis and a high operative risk. Cerebral embolisation seems inherent to TAVI, as illustrated by the consistent appearance of new brain lesions on post-procedural MRI studies. Embolic protection devices may capture or deflect embolised material en route to the brain and thus reduce TAVI-related brain injury. Histopathology studies of captured debris revealed a diverse aetiology including recent or organised thrombotic material, tissue originating from the aortic valve, atherosclerotic plaques or myocardium and foreign body components...

The use of embolic protection devices (EPDs) when treating coronary saphenous vein bypass grafts, performing carotid arterial stenting and treating acute coronary syndromes is well accepted. We will review currently available devices and approaches to reduce distal embolisation, first discussing their uses in carotid interventions and then in vertebral and peripheral vascular interventions.

Endovascular treatment has been the mainstay of therapy for repair of both ruptured and unruptured cerebral aneurysms. Flow diverter devices offer a new option for the treatment of complex aneurysms that were previously not amenable to coiling. Procedural adverse effects include intracranial haemorrhage and ischaemic stroke, which usually occur on the same day. Delayed complications are rare. We report a case of a patient who underwent placement of a pipeline embolisation device and developed delayed neurological deficits, which were thought to be an inflammatory reaction to the hydrophilic coating used in guidewires and microcatheters...

Three-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) can reliably detect dural arteriovenous fistula (dAVF); however, TOF source images should be checked in cases with low-flow dAVFs. A 69-year-old woman reported intractable pulsatile tinnitus after head trauma. It was difficult to diagnose dAVF using conventional MRA, but it was confirmed using a TOF source image. Cerebral angiography revealed a dAVF with a small shunted pouch draining into the sigmoid sinus, accompanying the arterial jet flow...

The most common benign liver tumours are haemangiomas, focal nodular hyperplasia and hepatocellular adenoma. We perform a review of the literature and show the current diagnostic and therapeutic modalities based on the EASL Clinical Practice Guideline. With the widespread use of ultrasound, the detection of liver lesions is increased. They are usually found in women of childbearing age with atypical abdominal pain or incidentally. Contrast-enhanced US, CT or MRI are usually necessary for differential diagnosis...

A 77-year-old Caucasian woman with recent abdominal surgery was diagnosed with multiple paradoxical systemic emboli in the mesenteric and renal circulation. Diagnosis was made by direct visualisation of a serpentine thrombus traversing both atria through patent foramen ovale (PFO) by transesophageal echocardiogram (TEE). Concomitantly, the patient was found to have deep venous thrombosis and pulmonary embolism. A decision was made to pursue cardiothoracic surgery preceded by inferior vena cava filter placement...
