RATIONALE: Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is characterized by a pattern of extravasated blood restricted to the perimesencephalic cisterns, normal angiographic findings, and an excellent prognosis with an uneventful course and low risks of complication. The precise etiology of bleeding in patients with PNSAH has not yet been established. The most common hypothesis is that PNSAH is venous in origin. Intracranial venous hypertension has been considered as the pivotal factor in the pathogenesis of PNSAH...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...

Arterial aneurysms are more common than visceral venous aneurysms. Portal vein aneurysms being the most common type of visceral venous aneurysms. Here, we present an 18-year-old young woman with thalassaemia major, who presented with headache, palpitation, shortness of breath and a recent increase in blood transfusion rate. On clinical examination, she had hepatosplenomegaly. Ultrasonography revealed hepatosplenomegaly with fusiform dilatation of extrahepatic portal vein, which was confirmed to be portal vein aneurysm on contrast enhanced CT...

Cervical carotid aneurysms are rare, and surgical treatment should be planned for each patient. The authors report 9 cases of cervical carotid aneurysm in 9 patients(mean age, 53.7 years;5 men)who were treated surgically between 2005 and 2014. The aneurysm was located in the internal carotid artery in 6 patients, the common carotid artery in 2 patients, and the carotid bifurcation in 1 patient. Four aneurysms were recurrences after a previous endovascular intervention(parent artery coil embolization, covered stent placement, or stent with coil embolization)...

BACKGROUND: The frontal bridging vein, which is the venous drainage route of the frontal cortex into the superior sagittal sinus (SSS), sometimes poses an obstacle in the anterior interhemispheric approach during surgery for anterior cerebral artery aneurysms. Although severe complications including venous infarction or edema due to damage to the bridging vein are well known, only a few reports have discussed how to avoid venous injury when we must sacrifice the bridging vein to obtain an appropriate surgical field...

INTRODUCTION: With the present disparity between organ availability and recipient demands, we reported our experience in transplanting kidneys with renal artery aneurysm after back-table reconstruction. METHODS: Four patients were identified. The repair consisted of excision of the aneurysm with ostial closure, and for one of the cases, an ovarian vein patch was used. We reviewed the safety and outcomes of this procedure. All donors were asymptomatic before surgery and were diagnosed incidentally during living donor evaluation...

BACKGROUND: Cardiovascular disease remains a major health care challenge. The knowledge about the underlying mechanisms of the respective vascular disease etiologies has greatly expanded over the last decades. This includes the contribution of microRNAs, endogenous non-coding RNA molecules, known to vastly influence gene expression. In addition, short interference RNA has been established as a mechanism to temporarily affect gene expression. This review discusses challenges relating to the design of a RNA interference therapy strategy for the modulation of vascular disease...

Aortic surgery results in ischemia-reperfusion injury that induces an inflammatory response and frequent complications. The magnitude of the inflammatory response in blood and bronchi may be associated with the risk of immediate complications. The purpose of the study was to evaluate bronchial microdialysis as a continuous monitoring of cytokines in bronchial epithelial lining fluid (ELF) and to determine whether bronchial ELF cytokine levels reflect the ischemia-reperfusion injury and risk for complications during open abdominal aortic aneurysm (AAA) repair...

We report the case of a 33-year-old man presented with a post-traumatic 20mm left ulnar artery aneurysm without intraluminal thrombus in the left hypotenar eminence. The patient reported left hand paraesthesia. Because of symptoms and the embolic risk we decide to plan an aneurysm resection and an interposition graft with inverted basilic vein for adequacy diameter (∼ 2mm), but an end-to-end anastomosis was performed instead. We think that the post traumatic distal artery aneurysm could be treated without a by-pass but, after a meticulous anatomic dissection, with a microvascular anastomosis between the artery stumps...

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...

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...
