OBJECTIVES: Cerebral arterio-venous malformations (AVM) are considered congenital lesions, emerging as an important cause of haemorrhagic stroke in children. The potential influence of age on clinical presentation and angio-architecture have been analysed extensively in the last years. Yet, comparative studies comprising ascending age groups may be limited in their conclusions, especially when comparing young children and adults. It is the aim of this study to evaluate characteristic clinical and angiographic features of AVM within a paediatric subgroup and their correlation to age at presentation...

INTRODUCTION: The association between lower-extremity venous thrombosis and cancer is well-established. However, the extent to which upper-extremity deep venous thrombosis (U-DVT) is a marker of cancer and a prognostic factor for all-cause mortality remains poorly understood. We examined the risk of cancer after a diagnosis of U-DVT compared with cancer risk in the general population. MATERIALS AND METHODS: Using Danish nationwide population-based medical registries, we identified all patients with first-time U-DVT during 1980-1993 and 2000-2013...

Aims: Heart failure (HF) is accompanied by major neuroendocrine changes including the activation of the natriuretic peptide (NP) pathway. Using the unique model of patients undergoing implantation of the CARMAT total artificial heart and investigating regional differences in soluble neprilysin (sNEP) in patients with reduced or preserved systolic function, we studied the regulation of the NP pathway in HF. Methods and results: Venous blood samples from two patients undergoing replacement of the failing ventricles with a total artificial heart were collected before implantation and weekly thereafter until post-operative week 6...

OBJECTIVE Transcranial color-coded duplex sonography (TCCS) is a reliable tool that is used to assess vasospasm in the M1 segment of the middle cerebral artery (MCA) after subarachnoid hemorrhage (SAH). A distinct increase in blood flow velocity (BFV) is the principal criterion for vasospasm. The MCA/internal carotid artery (ICA) index (Lindegaard Index) is also widely used to distinguish between vasospasm and cerebral hyperperfusion. However, extracranial ultrasonography assessment of the neck vessels might be difficult in an intensive care unit...

OBJECTIVE The rarity of cerebral dural arteriovenous fistulas (dAVFs) has precluded analysis of their natural history across large cohorts. Investigators from a considerable proportion of the few reports that do exist have evaluated heterogeneous groups of untreated and partially treated lesions. In the present study, the authors exclusively evaluated the untreated course of dAVFs across a multi-institutional data set to delineate demographic, angiographic, and natural history data. METHODS A multi-institutional database of dAVFs was queried for demographic and angiographic data as well as untreated disease course...

OBJECTIVE Pediatric cerebral venous sinus thrombosis has been previously described in the setting of blunt head trauma; however, the population demographics, risk factors for thrombosis, and the risks and benefits of detection and treatment in this patient population are poorly defined. Furthermore, few reports differentiate between different forms of sinus pathology. A series of pediatric patients with skull fractures who underwent venous imaging and were diagnosed with intrinsic cerebral venous sinus thrombosis or extrinsic sinus compression is presented...

Modern invasive treatment of superficial venous insufficiency of the lower extremities is largely based on the use of intravenous procedures under ultrasound guidance. The first-line treatment is thermoablation, in which the insufficient superficial vein, typically vena saphena magna or parva, is constricted by using laser or radio frequency energy under ultrasound guidance. The procedure is nearly always successful under local anesthesia and can be performed as an outpatient operation. When necessary, visible collateral varices can be treated with foam sclerotherapy or by surgical excision...

We quantify the impact of several variables including site of blood draw, delay in measurement, and use of the cyanide antidote hydroxocobalamin on detection of both normal (<2 mmol/L) and elevated (>6 mmol/L) human plasma lactate. An in vivo study assessed effects of venous or arterial origin of blood samples. Two in vitro studies assessed the effect of a 2 h delay in measuring plasma lactate concentrations, as well as the interference of low (100 μmol/L) and high (300 μmmol/L) plasma hydroxocobalamin concentrations on detecting normal and elevated levels of lactate...

Venous insufficiency of the lower limb is a common disease. Diagnosis is based on symptoms, clinical findings and duplex ultrasound. Consideration and planning of invasive treatment cannot be performed without ultrasound. Vast majority of invasive treatments in superficial venous insufficiency can be done by ultrasound-guided endovenous methods with local anesthesia. Thermoablation (laser of radiofrequency) is the first-line treatment. There are promisisng endovenous methods for treatment of deep venous obstruction in selected cases...

In reconstructive surgery, the ability to detect blood flow interruptions to grafted tissue represents a critical step in preventing postsurgical complications. We have developed and pilot tested a compact, fiber-based device that combines two complimentary modalities-diffuse correlation spectroscopy (DCS) and diffuse reflectance spectroscopy-to quantitatively monitor blood perfusion. We present a proof-of-concept study on an in vivo porcine model (n=8). With a controllable arterial blood flow supply, occlusion studies (n=4) were performed on surgically isolated free flaps while the device simultaneously monitored blood flow through the supplying artery as well as flap perfusion from three orientations: the distal side of the flap and two transdermal channels...

REVIEW
M Papamichail, M Pizanias, N Heaton
Congenital portosystemic venous shunts are rare developmental anomalies resulting in diversion of portal flow to the systemic circulation and have been divided into extra- and intrahepatic shunts. They occur during liver and systemic venous vascular embryogenesis and are associated with other congenital abnormalities. They carry a higher risk of benign and malignant liver tumors and, if left untreated, can result in significant medical complications including systemic encephalopathy and pulmonary hypertension...

BACKGROUND AND PURPOSE: Type I and IIa dural arteriovenous fistulas (DAVFs) have a low hemorrhagic risk, but are often the cause of debilitating tinnitus that requires treatment. While Onyx® and PHIL™ (Precipitating hydrophobic injectable liquid) transarterial embolization represent the first endovascular option, there are occasional cases where performing angioplasty and stenting of the affected sinus may lead to satisfactory results. MATERIAL AND METHODS: We retrospectively analyzed four consecutive cases of patients with DAVF-induced pulsatile tinnitus secondary to type I and II DAVFs who were treated with angioplasty and stenting of the sinus only...

BACKGROUND Celiacomesenteric trunk (CMT) is a very rare anatomic finding in which the celiac artery and the superior mesenteric artery (SMA) originate from the abdominal aorta through a common trunk. Clinical associations with CMT include arterial aneurysm, thrombosis, and celiac artery compression. However, an association between CMT and abdominal venous congestion caused by left renal vein compression, or 'nutcracker phenomenon,' has not been previously reported.
