BACKGROUND: Dural arteriovenous fistulas (DAVFs) are usually seen in relation to the venous sinuses, but in certain rare instances fistulas may not drain directly into the venous sinuses but rather drain into the cortical veins. This rare form of DAVF may present with either intracranial hemorrhage or myelopathy. The mode of clinical presentation is influenced by the venous outflow into either intracranial drainage or caudally intraspinal drainage. OBJECTIVE: To evaluate the clinical presentations, angioarchitectural characteristics, and treatment of 12 patients who presented with DAVF in the region of the foramen magnum...

Iatrogenic venous pseudoaneurysm (VP) formation after venipuncture is rare. This report showed 2 cases of VP following venipuncture, and VPs were resected surgically. A 58-year-old woman and a 56-year-old woman developed a soft antecubital mass after blood sampling from the basilic veins. One patient had the sensory disturbance of forearm. The mass was diagnosed as a VP with thrombus by duplex ultrasound and magnetic resonance imaging. The aneurysm was resected completely, and the sensory disturbance of the patient was improved...

A portal vein aneurysm is the dilatation of the portal vein due to a defect in the vein wall. This rare disease manifestation is difficult to predict and has the potential for severe complications. We describe the case of a 68-year-old man involved in a motor vehicle collision who presented with abdominal hemorrhage found on ultrasound, hypotension, and vague abdominal pain. The patient underwent an exploratory laparotomy to control bleeding. Surgery and a subsequent abdominal computed tomography revealed the presence of a portal vein pseudoaneurysm and shock bowel...

OBJECTIVE: Conflicting data exist on outcomes of open vein harvest (OVH) and endoscopic vein harvest (EVH) for infrainguinal bypass. The purpose of this study was to compare outcomes between OVH and EVH in femoral to popliteal artery bypasses. METHODS: A retrospective review was performed of all patients undergoing common femoral to popliteal artery bypass with great saphenous vein between January 1997 and June 2014. Bypasses using arm or composite vein were excluded, as were those performed for popliteal artery aneurysms or trauma...

A carotid-cavernous fistula (CCF) is an abnormal communication between arteries and veins within the cavernous sinus and may be classified as either direct or dural. Direct CCFs are characterized by a direct connection between the internal carotid artery (ICA) and the cavernous sinus, whereas dural CCFs result from an indirect connection involving cavernous arterial branches and the cavernous sinus. Direct CCFs frequently are traumatic in origin and also may be caused by rupture of an ICA aneurysm within the cavernous sinus, Ehlers-Danlos syndrome type IV, or iatrogenic intervention...

Thoracic venous aneurysms are a rare clinical entity and contrast-enhanced computed tomography has been the cornerstone of their diagnosis. We are reporting a rare case of isolated left brachiocephalic vein aneurysm, which was surgically managed, highlighting the role of dynamic contrast-enhanced magnetic resonance imaging as a definitive diagnostic modality in this patient.

Vein of Galen aneurysmal malformations (VGAMs) are complex vascular lesions. Their etiopathogenesis is extensively debated and remains poorly understood. Strictly speaking, true VGAMs are Galenic pial arteriovenous fistulas. They are believed to arise in utero and are contended to drain either into the true vein of Galen or the median prosencephalic vein of Markowski. Several classification systems have been proposed and are widely used. With the advent of endovascular therapy, precise understanding of the angioarchitecture is critical for management and therapeutic decision making...

Visceral venous aneurysms are uncommon and renal vein aneurysms are among the rarest in this subset. Renal vein aneurysms are frequently asymptomatic, but patients may present with flank pain or hematuria. Complications of untreated visceral venous aneurysms include thrombus formation and, very rarely, rupture. Treatment of renal vein aneurysms ranges from watchful waiting to surgical repair. We describe a patient with renal vein aneurysm presenting with recurrent pulmonary embolus with no other identifiable source...

Vascular diseases account for a significant proportion of abdominal pathology and represent a common referral source for abdominal ultrasonographic examinations. B-mode, color Doppler, and spectral Doppler analyses are well-established in the evaluation of abdominal blood vessels although they may occasionally be limited by lower sensitivity for slow flow visualization or the deeper location of abdominal vascular structures. The introduction of microbubbles as ultrasonographic contrast agents has rendered contrast-enhanced ultrasound (CEUS), a valuable complementary ultrasonographic technique, which is capable of addressing clinically significant problems and guiding patient management...

Saphenous vein graft (SVG) aneurysms (SVGA) after renal transplantation represents a rare vascular complication with subsequent challenging multidisciplinary treatment. We present a case of a 30-year-old female who received a live donor kidney transplantation for end-stage renal disease that was caused due to the hemolytic uremic syndrome. Postoperatively, an insufficient graft perfusion due to an arterial kinking was noted and repaired using an autologous SVG interposition. Ten years later, a 3-cm aneurysm of the SVG at the anastomotic site with the common iliac artery was discovered...

A 40-year-old man with a history of oral and ileocecal ulcers, acneiform lesions, erythema nodosum and deep vein thrombosis presented with fever, abdominal pain and a pulsatile mass in the right groin. Two months prior to the presentation, he underwent stent grafting via the right femoral artery for an abdominal aortic aneurysm. Enhanced computed tomography disclosed aneurysms at the both ends of the stent (blue and green arrows in the panels A and B) and at the right femoral puncture site (blue arrowhead)...

Gonadal vein aneurysm is a very rare anomaly and the aetiology is often unknown. Many factors have been said as contributory such as multiple pregnancies, multiple pelvic surgeries, pelvic tumours or pelvic congestion, but none of them have been strongly or closely associated with the lesion. Here, we present a case of left gonadal vein aneurysm in a female with its management. A 72-year-old, diabetic and hypertensive female presented with complaints of left loin pain. She is multiparous with four normal vaginal deliveries...

Kawasaki disease (KD) is an autoimmune disorder that can induce coronary artery aneurysms, particularly in the case of delayed diagnosis and/or treatment. Early diagnosis is important for treatment and reduces the risk of heart injury. The aim of the present study was to identify differentially expressed genes by comparing the levels of gene expression in human umbilical vein endothelial cells following treatment with plasma from healthy individuals and patients with acute or convalescent KD. Following comparison of the control and acute KD groups, 385 up-regulated and 537 down-regulated genes were identified in the acute KD group...

BACKGROUND: Although the indications for endovascular aneurysm repair for abdominal aortic aneurysm have been expanding, our primary strategy for pararenal and juxtarenal abdominal aortic aneurysm (P/JRAA) is open surgery (OS). One consequence of OS for P/JRAA is transient renal ischemia owing to renal artery clamping, which can be followed by acute kidney injury (AKI). Prior studies referred to the impact of renal ischemia on AKI, but they have rarely evaluated longer-term renal function...

Thoracic venous aneurysms are very rare conditions, even more unusual from left innominate vein. We report a case of a 57-year-old male who presented an anterior mediastinal mass suspicious of thymoma by chest computed tomography. Median sternotomy was performed aiming for total thymectomy, but intraoperative findings and final pathology confirmed the diagnosis of left innominate vein aneurysm. The patient underwent aneurysmectomy and reconstruction of the left innominate vein. The patient remains well 2 years after surgery...
