INTRODUCTION: Cerebral cortical venous aneurysm also known as cerebral varix is a rare entity that usually occurs in relation to high-flow draining veins of arteriovenous fistulas, arteriovenous malformations, and venous angioma. Isolated cerebral varix is an extremely rare entity. CASE REPORT: We present a 1-year-old male with isolated cerebral varix. During follow-up, the varix thrombosed spontaneously without causing any neurological deficits. CONCLUSION: To the best of our knowledge, spontaneous asymptomatic thrombosis of an isolated cerebral varix without any clinical finding was reported for the first time in the literature...

A 73-year-old man, who had undergone coronary artery bypass grafting (CABG) 10 days prior, presented with a great saphenous vein graft aneurysm (SVGA). CT revealed the increasing size of the aneurysm. Since the SVGA occurred immediately after CABG and there were no other complications, the aneurysm was treated percutaneously. While intravascular ultrasonography (IVUS) and optical coherence tomography failed to detect the entry point, an IVUS catheter with the addition of ChromaFlo imaging clearly revealed the entry point, size and length of the SVGA...

Objectives Treatment options for venous insufficiency are rapidly evolving in the office setting and include venography, intravascular ultrasound, and venous stenting. Non-thrombotic iliac vein lesions assessment and treatment in an office setting is currently an area of interest. The purpose of this study is to demonstrate the safety and efficacy of evaluating non-thrombotic iliac vein lesion with this office-based procedure in octogenarians and nonagenarians. Methods From January 2012 through December 2013, 300 non-thrombotic iliac vein lesion limbs in 192 patients with venous insufficiency ≥80 years old were evaluated for non-thrombotic iliac vein lesion...

Oxidative stress is implicated in the pathophysiology of vascular diseases, including atherosclerosis, aneurysm and arteriovenous fistula. A previous study from our lab suggested that microRNA (miR)‑4463 may be involved in the pathogenesis of vascular disease; however, the roles of oxidative stress in the molecular mechanisms underlying the actions of miR‑4463 in vascular disease have yet to be elucidated. The aim of the present study was to investigate the role of miR‑4463 in hydrogen peroxide (H2O2)‑induced oxidative stress in human umbilical vein endothelial cells (HUVECs)...

Venous aneurysms are rare lesions, they have been reported in most venous territories. Abdominal location is unusual. A 61-year-old man presented with chest pain and dyspnea attributed to pulmonary embolism. Computed tomography of the abdomen showed multiple thrombosed venous aneurysms of the left external iliac vein and the inferior vena cava. There were no signs of rupture. The patient received anticoagulant treatment. He had no surgical treatment.

A venous aneurysm (VA) is a relatively rare disease defined by cystic vasodilated lesions in a general vein. Popliteal venous aneurysm (PVA) is a rare clinical entity, and the first signs may be a thromboembolic event. They can cause potentially life-threating diseases, such as pulmonary embolism and deep venous thrombosis. A left-sided inferior vena cava (IVC) is a common anomaly associated with venous thrombus, resulting in anatomical variations in the venous return from the lower limbs. The general vascular malformation of PVA and left-sided IVC should also be preoperatively understood because of the unpredictable risk of thromboembolic complications...

PURPOSE AND METHODS: Superselective transvenous embolization (TVE) with liquid embolic agents is a new concept in treatment of vein of Galen aneurysmal malformations (VGAM). We performed ten sessions of TVE in VGAM patients with restricted transarterial access. In this paper, we assessed clinical and angiographic outcomes of the proposed treatment and discussed three different TVE techniques with regard to morphology of the shunt and outflow tract. Safety and avoidance-of-complication tips were also discussed...

In 1997 D’Andrea et al. described a new nosological entity the characteristics of which consisted of lengthening, dilation and tortuosity of blood vessels, arteries or veins, less prominent, but also less circumscribed than an aneurysm. This condition does not necessarily imply specific aneurysm formation although aneurysms at multiple sites are a frequent observation. The term used by authors for angiomegaly of the venous system was venomegaly and the analogous condition of the arterial system was termed arteriomegaly...

A 69-year-old man was referred urgently for a 58-mm enlarging painful right internal iliac artery (IIA) aneurysm. Since exclusion through proximal IIA coverage and distal IIA branches embolization had been previously performed, aneurysm sac puncture through the iliac vein was decided. The ipsilateral common femoral vein was antegradely punctured, and a 16.5 G Ross modified Colapinto needle from a transjugular intrahepatic access set was used to puncture the sac and fill the aneurysm with coils. Embolization of an IIA aneurysm through the iliac vein may represent an alternative when prior IIA aneurysm exclusion has been performed...

C Stelzner, N Abolmaali, U Hecker, S Schellong
Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound...

Subcortical arteriovenous malformations (AVMs) are surgically challenging. Localization is crucial for eloquent areas, and complete resection evaluation is uncertain. Indocyanine green videoangiography (ICG-VA) can assist this surgery. An illustrative video of a subcortical frontoparietal bleeding AVM resection assisted by ICG-VA is presented. A bleeding arterial feeder aneurysm was embolized in the acute phase to protect against rebleeding. ICG-VA helped to detect the AVM's superficial arterialized draining vein, distinguishing it from normal cortical veins...

A 46-year-old male presented with an incidentally discovered left ventricular body arteriovenous malformation (AVM). It measured 2 cm in diameter and had drainage via an atrial vein into the internal cerebral vein (Spetzler-Martin Grade III, Supplementary Grade 4). Preoperative embolization of the posterior medial choroidal artery reduced nidus size by 50%. Subsequently, he underwent a right-sided craniotomy for a contralateral transcallosal approach to resect the AVM. This case demonstrates strategic circumferential disconnection of feeding arteries (FAs) to the nidus, the use of aneurysm clips to control large FAs, and the use of dynamic retraction and importance of a generous callosotomy...

Vascular diseases of the spleen are relatively uncommon in the clinical practice. However, the reported incidence has been progressively increasing, probably due to advances in the imaging modalities used to detect them. This disease condition often presents with non-specific clinical manifestations, but can be associated with significant morbidity and mortality. This review article aims to provide updated clinical information on the different vascular diseases of the splenic vasculature-splenic vein thrombosis, splenic vein aneurysm, splenic artery aneurysm, splenic arteriovenous fistula, and spontaneous splenorenal shunt-in order to aid clinicians in early diagnosis and management...

Aneurysm of the proximal ulnar artery is extremely rare. Ultrasonography, computed tomography and magnetic resonance imaging generally provide accurate diagnosis of aneurysm. A 29 year-old woman who had undergone an excision biopsy of a mass in her right arm by an orthopedic surgeon was referred to our department. We resected the mass and interposed it with a reversed great saphenous vein. Histopathological examination suggested that the mass was a pseudoaneurysm consisting of organized thrombi with recanalization...

BACKGROUND: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra-anatomical bypass grafting; however, the use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic hemorrhage, limb occlusion, and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...

Behçet's disease (BD) is systemic vasculitis of unknown etiology, which is more common in the countries located along the Great Silk Road. The disease is diagnosed if a patient has 4 key diagnostic signs: aphthous stomatitis, genital sores, and eye and skin lesions. Vascular diseases referred to as minor criteria for BD are characterized by the formation of aneurysms and thrombosis, predominantly in the venous bed. In venous disorders, a blood clot can form in any vessel, including caval, cerebral, pulmonary, and other veins...

OBJECTIVE: Azygos vein aneurysms (AVAs) are uncommon and infrequently diagnosed. When confronted with a patient presenting with an AVA, physicians can rely on only a few case reports after an extensive literature search. To date, no guideline, no rule, and no review on the optimal treatment strategy for these patients exist. METHODS: A PubMed and MEDLINE database search for papers and case reports describing AVA was performed. Cases from our own institutions were also reviewed...
