Posterior condylar canal dural arteriovenous fistula (PCC dAVF) is a rare entity with only three cases having been reported so far in the English literature. We describe the clinical presentation, imaging, and endovascular management of an elderly man with left PCC dAVF presenting with subarachnoid haemorrhage (SAH). Endovascular management of such cases requires thorough understanding of the vascular anatomy around the craniovertebral junction (CVJ) and variable bridging vein draining patterns. The fistula in our case was fed by the posterior meningeal branch of the left vertebral artery and was draining through a dilated and tortuous medullary bridging vein into the antero-lateral pontomedullary venous system...

Tumor-suppressing subchromosomal transferable fragment cDNA 6 (TSSC6) expression is restricted to hematopoietic organs and tissues where it plays a role in hematopoietic-cell function. The ADP purinergic receptor P2Y12 is mainly expressed by platelets with important clinical significance as a target for several clinically approved antithrombotic agents. We have previously shown a physical association between P2Y12 and TSSC6 in platelets. Hence our aim was to investigate whether this physical association is translated to functional effects...

PURPOSE: A highly variable prostatic artery origin coupled with frequent anastomoses to adjacent organs makes prostate artery embolisation a challenging procedure. Despite CT angiography facilitating procedural planning, it is not performed in all centres. Therefore, we explored the utility of prostatic CT angiography by assessing its capacity to identify the prostatic arteries and highlight troublesome anastomoses. MATERIALS AND METHODS: A retrospective review of patients undergoing prostate artery embolisation for symptoms of benign prostatic obstruction between June 2012 and October 2016 was conducted, with analysis of the pre-procedural CT angiography...

Retinal artery occlusions are acute vascular diseases. Very often they are caused by an embolisation. Rarely a thrombosis is caused by an arteriitis. In the acute phase diagnosis in most of the cases can be made by ophthalmoscopy due to the whitish retinal edema and in central retinal artery occlusion the cherry red spot. Difficulties in making the diagnosis can occur in the chronic stage, especially after reperfusion of the retinal vessels, when the fundus colour returned to normal again. Several diagnostic procedures help to make the diagnosis...

Inflammatory bowel disease is closely associated with an increased risk for thrombotic events. Thrombosis mostly occurs in the extremities, lungs, and liver; but it can also occur in the ventricles of the heart. The primary goal of this article is to increase awareness of the risk for ventricular thrombosis in this patient population among healthcare professionals and, thus, appropriate prompt use of thromboprophylaxis therapy for these patients during acute flare-ups. Early diagnosis and intervention are critical for ventricular thrombosis to prevent systemic embolisation of the thrombus...

Arteriovenous malformations (AVM) of the inferior mesenteric artery are rare. They may be primary (congenital or idiopathic) or secondary (acquired) after trauma or of iatrogenic origin. Of the abdominal AVM, the inferior mesenteric trunk is the least commonly involved. Most reported cases are of iatrogenic origin, resulting from colon surgery. Only 17 cases have been described and published in the literature. The objective of this work is to make known a case treated in our center. We present a case of 73-year old male, who came to the emergency service with symptoms of abdominal distension, pain lasting 48 hours along with months of diarrhoea...

Pulmonary arteriovenous malformations (PAVMs) are structurally abnormal vascular communications that provide a continuous right-to-left shunt between pulmonary arteries and veins. Their importance stems from the risks they pose (>1 in 4 patients will have a paradoxical embolic stroke, abscess or myocardial infarction while life-threatening haemorrhage affects 1 in 100 women in pregnancy), opportunities for risk prevention, surprisingly high prevalence and under-appreciation, thus representing a challenging condition for practising healthcare professionals...

Schistosomiasis is one of the most prevelant parazitic diseases in the world. It is endemic in more than 70 countries, and more than 200 million people worldwide are infected with Schistosoma. Pulmonary hypertension (PHT) is one of the chronic complications of schistosomiasis. The exact pathogenesis of schistosomiasis-associated pulmonary hypertension (S-PHT) remains unclear, although several mechanisms such as parazitic arterial embolisation, pulmonary arteriopathy, and portopulmonary hypertension have been suggested...

A 64 year-old man with pituitary adenoma developed massive epistaxis after an uneventful endoscopic transsphenoidal surgery. Angiography showed extravasation from the sphenopalatine artery, to which embolisation was performed. An incidentally coexisting ethmoidal dural arteriovenous fistula supplied by the ophthalmic artery aberrantly originated from the middle meningeal artery caused increased haemorrhage.

Ectasias and coronary aneurysms are uncommon coronary artery diseases, can coexist and are poorly known. Their principal etiology in adults is coronary atherosclerosis. It has been suggested that these abnormalities would have poor prognosis and that slow flow could lead to in situ thrombosis and distal embolisation. However, ectasias and aneurysms are most often associated with coronary stenosis. We report a series of 47 cases of ectasias and coronary aneurysms with evaluation of the clinical and angiographic characteristics, the therapeutic choices and we review the literature concerning these lesions...

Background: The local injection of novel cardioprotective study drugs prior to percutaneous coronary intervention could cause embolisation of thrombus, resulting in increased reperfusion injury and subsequent infarct size. The aim of this study was to assess the safety of the delivery of an intracoronary therapy delivered during primary percutaneous coronary intervention for acute myocardial infarction prior to the re-establishment of thrombolysis in myocardial infarction III flow. Methods: One hundred sixty-seven patients with acute myocardial infarction successfully reperfused through primary percutaneous coronary intervention and undergoing Cardiac MRI within the first week after reperfusion were studied...

Background: Neuroendocrine tumours (NETs) are a heterogeneous group of diseases that can originate from any part of the gastrointestinal tract, bronchi, thyroid and pancreas. These tumours may be functioning or not depending on their ability to produce active substances, such as adrenocorticotrophic hormone (ACTH). ACTH-producing pancreatic neuroendocrine tumours are rare, with limited data about effective antitumor therapies. Case Report: A 58-year-old man with a history of type-2 diabetes mellitus and arterial hypertension was diagnosed with Cushing's syndrome (CS) secondary to an ACTH ectopic production from a well-differentiated neuroendocrine tumour of the pancreas metastatic to the liver...

INTRODUCTION: Pulmonary arteriovenous malformations (PAVMs) may not be amenable to treatment by embolisation or surgical resection, and many patients are left with significant hypoxaemia. Lung transplantation has been undertaken. There is no guidance on selection criteria. METHODS: To guide transplantation listing assessments, the outcomes of the six patients who had been considered for transplantation were compared with a similarly hypoxaemic patient group recruited prospectively between 2005 and 2016 at the same UK institution...

OBJECTIVES: To evaluate the risk factors for haemoptysis after cone-beam computed tomography (CBCT)-guided percutaneous transthoracic needle biopsy (PTNB), particularly on whether the enlargement of main pulmonary artery diameter (mPAD) is a risk factor for PTNB-related haemoptysis. METHODS: 4,172 cases of CBCT-guided PTNBs in 3,840 patients were retrospectively included in this study. Various data including mPAD measured on preprocedural CT images were evaluated using logistic regression analyses to determine significant risk factors for both haemoptysis and severe haemoptysis, designated as when blood transfusion, vascular embolisation or cardiopulmonary resuscitation were required to manage patients with haemoptysis...
