OBJECTIVE: While vein of Galen aneurysmal malformations (VGAM) can be diagnosed in the fetus, the challenge is predicting the occurrence of its two major complications: cardiopulmonary failure and encephalomalacia. This study attempts to determine which fetal brain MRI features might be used to predict the development of these complications at birth. METHODS: The cohort was extracted from a prospectively-assembled database of VGAM cases managed at a single referral centre from 2000 to 2014...

A wide range of clinically important anatomic variants and pathologic conditions may affect the renal vasculature, and radiologists have a pivotal role in the diagnosis and management of these processes. Because many of these entities may not be suspected clinically, renal artery and vein assessment is an essential application of all imaging modalities. An understanding of the normal vascular anatomy is essential for recognizing clinically important anatomic variants. An understanding of the protocols used to optimize imaging modalities also is necessary...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

Venous aneurysms of the jugular vein are one of the rare causes of neck swelling, and primary venous aneurysms of the external jugular vein are extremely rare. A 46-year-old woman presented with a painless and suddenly growing mass in the left neck. A computed tomography angiography revealed a fusiform venous aneurysm of the external jugular vein containing intraluminal thrombus. We performed resection of the aneurysm and ligation of the external jugular vein. Removal of the aneurysm of the neck vein was necessary because venous aneurysms with thrombosis may lead to serious thrombotic complications such as pulmonary embolism...

BACKGROUND: Optic neuropathy is a disorder characterised by dysfunction or destruction of the optic nerve tissues. Acquired causes include interruption in the blood supply, nutritional deficiency, compression by a tumour or aneurysm, trauma, and toxic types (Ambizas and Patel In US Pharm 36(4):HS2-HS6, 1). Drug-induced optic neuropathy is of the toxic type and can be defined as a clinical syndrome characterised by papillomacular bundle damage, central, or cecocentral scotoma, and reduced colour vision (Ambizas and Patel In US Pharm 36(4):HS2-HS6, 2011; Sharma and Sharma In Indian J Ophthalmol 59(2):137-141, 2)...

Brachial artery (BA) aneurysms are rare, and most are false aneurysms. Although true BA aneurysms have been reported, most have been reported without symptoms. A 65-year-old man was referred due to a left upper limb mass with rest pain and slight ulceration of the left second and third fingers. As enhanced computed tomography revealed the patency of only the left proximal and distal BA as well as the thrombosed mass, excision of the aneurysm and BA replacement were performed with a great saphenous vein graft...

Nontraumatic spontaneous rupture of a bronchial artery aneurysm is rarely seen. In this report, we described such a phenomenon in a patient induced by usage of anticoagulant agent. The patient had no antecedent history of trauma, hypertension, or apparent aortic pathology. The patient who had been taking low-molecular-weight heparin and warfarin to treat deep vein thrombosis complained of a sudden upper abdomen pain with shortness of breath and hypoxemia. The patient was diagnosed and treated for an acute hemomediastinum caused by a ruptured bronchial artery aneurysm...

Giant coronary artery aneurysms are rare clinical entities. We report the case of a 49-year-old man who presented with dyspnoea and exertional chest pain. Investigations confirmed an aneurysmal right coronary artery measuring 4 cm with a fistulous communication to the right atrium. Following right atriotomy, the fistula was oversewn and the aneurysmal right coronary artery ligated at its origin and at several points along its course. A saphenous vein graft was anastomosed to the posterior descending artery...

Preoperative three-dimensional (3-D) visualization of brain vasculature by digital subtraction angiography from computerized tomography (CT) in neurosurgery is gaining more and more importance, since vessels are the primary landmarks both for organs at risk and for navigation. Surgical embolization of cerebral aneurysms and arteriovenous malformations, epilepsy surgery, and stereoelectroencephalography are a few examples. Contrast-enhanced cone-beam computed tomography (CE-CBCT) represents a powerful facility, since it is capable of acquiring images in the operation room, shortly before surgery...

BACKGROUND: Venous aneurysms of the upper torso are uncommon in contrast to the abdomen and lower extremities. Mostly silent, they can cause significant morbidity. Large or symptomatic venous aneurysms are generally treated with open resection. To our knowledge, there are no documented cases of head and neck venous aneurysms treated by a hybrid endovascular and open approach. CASE PRESENTATION: A 56-year-old female presented with the complaint of pain and increasing size of a supraclavicular mass...

We report a case of a symptomatic and rapidly expanding aneurysm of an in-situ saphenous vein graft in a 70-year-old man with extensive prior open and endovascular procedures for aneurysmal disease. He was was found to have full-length aneurysmal dilation with rapid progression over the course of six months. Successful ligation and exclusion with subtotal excision of the aneurysmal segment was performed and revision bypass was foregone due to adequate distal perfusion via collateralization. This rare complication of autologous vein bypass graft typically occurs at the anastomoses and merits aneursymorrhaphy or ligation...

BACKGROUND: Visceral venous aneurysms are exceedingly rare, and until now, there have been no reports of this phenomenon in the adrenal vasculature. This report details the first adrenal venous aneurysm reported in the literature. The aneurysm presented as an 18-cm mass that was initially suspected to be a hematoma or tumor on the basis of the complex medical history of the patient, which included hemophilia A and testicular cancer. After surgical excision, pathologic examination confirmed this mass to be a 15...

The usual manifestation of brachial artery aneurysms is the incidental finding of a swelling of the arm, combined with paresthesia or pain in some cases. The etiology is often traumatic or secondary to drug abuse. Pathophysiology of brachial artery dilation in these cases is not completely clear. We herein describe a case of a 61-year-old male presenting with a giant, painful, pulsatile mass on his left arm. He was submitted to a cadaveric kidney transplant in 2005. He had a functioning arteriovenous fistula (AVF) on his right arm, and a spontaneously thrombosed radiocephalic AVF on his left arm...

Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril...

Behçet's disease is a multisystem disorder with unknown etiology and a unique geographic distribution. The disease is characterized by recurrent skin-mucosa lesions and sight-threatening panuveitis. Vascular involvement, which is more common and more severe among males, has also equally characteristic features such as affecting mostly veins, having a significant tendency for thrombosis, and running a relapsing course. Lower extremity vein thrombosis (LEVT) is the most frequent manifestation, followed by vena cava inferior thrombosis...

Theoretical properties of a multi-scale opening (MSO) algorithm for two conjoined fuzzy objects are established, and its extension to separating two conjoined fuzzy objects with different intensity properties is introduced. Also, its applications to artery/vein (A/V) separation in pulmonary CT imaging and carotid vessel segmentation in CT angiograms (CTAs) of patients with intracranial aneurysms are presented. The new algorithm accounts for distinct intensity properties of individual conjoined objects by combining fuzzy distance transform (FDT), a morphologic feature, with fuzzy connectivity, a topologic feature...
