From February to August28 cases of uterine myomas were under-gone bilateral arterio -embolization of tumor feeding vessels. Interventional treatment for uterine myoma is definite effective especially in submucosal uterine myoma. Los primeros premolares superiores presentan uno, dos y tres conductos.

La presencia de tres conductos tiene una baja prevalencia. Intracranial dural arterio -venous fistula presenting with progressive myelopathy. Spinal dural arterio -venous fistula DAVF is rare and usually involves the thoracic segments. The classical presentation is a slowly progressive ataxia. Patients may present with pulsatile tinnitus, occipital bruit, headache, dementia, visual impairment as well as neurological deterioration distant from the DAVF as a result of venous hypertension and cortical haemorrhage.

The authors present a rare case of progressive myelopathy secondary to an intracranial DAVF. Descartando la reapertura del conducto arterioso. Occupational therapy for patients with an arterio -venous fistula.

Full Text Available End stage renal disease ESRD represents a chronic medical condition that has become a public health problem and requires substantial funding. The number of patients with ESRD is rapidly increasing. From the moment that ESRD is diagnosed, the natural evolution of this pathology is towards mandatory dialysis, in absence of a renal transplant procedure.

In order to perform hemodialysis, a vascular access site must be created and maintained functional. A proper vascular access site allows an adequate blood flow through the dialysis machine, in order to obtain the required results. The arterio -venous fistula represents the number one recommended vascular access site procedure.

Establishing and maintaining a vascular access represents one of the biggest problems in hemodialysis. Maintaining a good quality vascular access site is a demanding process and requires cooperation between both the patient and the health care providers. For ESRD patients there is a constant concern regarding the patency of their vascular access.

The aim of this paper is to present the postoperative measures that ESRD patients should provide in order to preserve their vascular access. Also, we want to present the main signs of an early complication that patients should recognize and therefore immediately present themselves to the physician. By establishing this type of cooperation and trust between the patient and the medical staff we will be able to reduce the number of surgical procedures required for the creation and maintenance of the vascular access.

Suppressing unsteady flow in arterio -venous fistulae. Arterio -Venous Fistulae AVF are regarded as the “gold standard” method of vascular access for patients with end-stage renal disease who require haemodialysis. Unphysiological flow patterns, including high-frequency flow onfalomesenterjco, associated with the unnatural and often complex geometries of AVF are believed to be implicated in the development of IH.


In the present study, we employ a Mesh Adaptive Direct Search optimisation framework, computational cknducto dynamics simulations, onfalkmesenterico a new cost function to design a novel non-planar AVF configuration that can suppress high-frequency unsteady flow.

A prototype device for holding an AVF in the optimal configuration is then fabricated, and proof-of-concept is demonstrated in a porcine model.

Results constitute the first use of numerical optimisation to design a device for suppressing potentially pathological high-frequency flow unsteadiness in AVF. Persistencia del conducto onfalomesenterico. Arterio -venous anastomoses in isolated, perfused rat lungs. We used a flow cytometer to count particle appearances in venous effluent samples collected every 0. Cumulative percentages of infused particles that appeared in the samples averaged 3.

This article is a U. Government work and is in the public domain in the USA. Physiological Reports published by Wiley Periodicals, Inc. Fanconi anaemia with bilateral diffuse pulmonary arterio venous fistulae: Full Text Available Abstract Background We report a patient with cytogenetically confirmed Fanconi anaemia with associated diffuse bilateral pulmonary arterio -venous fistulae. This is only the second reported case of diffuse pulmonary arterio -venous fistulae with Fanconi anaemia.

Both central and peripheral cyanosis plus clubbing were noted on examination. The peripheral saturation was persistently low on room air and did not improve with supplementary Oxygen. Contrast echocardiography failed to demonstrate an intra cardiac shunt but showed early crossover of contrast, suggesting the possibility of pulmonary arterio -venous fistulae.

Computed tomography pulmonary angiogram was inconclusive. Subsequent right heart catheterisation revealed bilateral diffuse arterio -venous fistulae not amenable for device closure or surgical intervention.

Conclusion To our knowledge, this is the second reported patient with diffuse pulmonary arterio -venous fistulae associated with Fanconi anaemia. We report this case to create awareness among clinicians regarding this elusive association.

We recommend screening patients with Fanconi anaemia using contrast echocardiography at the time of assessment with transthoracic echocardiogram. Though universal screening may be impossible given the cost constraints, such screening should at least be performed in patients with clinical evidence of desaturation or when a therapeutic option such as haematopoietic stem cell transplantation is considered.

Treatment of pulmonary arteriovenous fistulae would improve patient outcome as desaturation by shunting worsens the anaemic symptoms by reducing the oxygen carrying capacity of blood. We report a year-old man with recurrent variceal bleeding due to portal hypertension caused by multiple intrahepatic arterio -portal venous fistulas, which were successfully occluded by embolization with n-butyl cyanoacrylate and micro-coils.

Arterio -venous flow between monochorionic twins determined during intra-uterine transfusion. Nonlinear decay of adult red blood cells. Recently, we derived equations relating the flow of adult red blood cells through a placental arterio -venous anastomosis with intra-uterine and post-natal measured adult hemoglobin concentrations.

Vitelline duct – Wikidata

In this letter, we re-derived the equations, now including a more realistic nonlinear decay of adult red blood cells, and re-evaluated the measurement accuracy of the arterio -venous flow and the lifetime of the red blood cells. Quantitative determination of peripheral arterio -venous shunts by means of radioactively labelled microspheres. In the present work a nuclear method of quantitative measurement of confucto arterio -venous shunts with a whole-body scanner is standardized.

This method, developed at the beginning of the onfalomesentwrico at Tuebingen, stands out in contrast with earlier measuring methods by the application of the theory of quantitative scintiscanning. This means that the scintigram obtained after injection of sup 99m technetium-labelled human albumin microspheres into an artery before the shunt is corrected for the quantitative shunt calculation by several factors using a computer, to avoid systematic mistakes.


For the standardization of the method, scintigrams were taken during model experiments and experiments on animals and human beings. A review of 50 cases with cerebral arterio. Clinical records, surgical techniques and pre- and post-operative studies were evaluted by retrospective analysis. The more important onfalomewenterico were the frecuency of presentations in male patients from the coast, the clinical onset with intracraneal hemorrhage, the onfakomesenterico technique of drain Se reconoce la diversidad de formas de vejiga urinaria.

Se manifiesta en algunas especies el dimorfismo sexual en la forma de las papilas urinaria y urogenital. By means of an anatomical analysis from 70 species of teleostean fishes, belonging to 62 genera, and 39 families, and 20 orders, the morphological diversity of the urinary Duch system is described.

A general morphological teleostean pattern is defined as the fusion of both archinephric ducts in the common urinay duct, and the fusion in malesof the common urinary duct with the common spermatic duct in the urogenital duct.

A relation between the length of thekidney and of the archinephric ducts is recongnized. The origin of the urinary bladder from the common urinary duct is suggested.

Differential kinetics of response and toxicity using stereotactic radiation and interventional radiological coiling for pulmonary arterio -venous shunting from metastatic leiomyosarcoma. Case report demonstrating the differential kinetics of response and toxicity using stereotactic radiation and interventional radiological coiling for pulmonary arterio -venous shunting from leiomyosarcoma pulmonary metastases. Monitoring arterio -venous differences of glucose and lactate in the anesthetized rat with or without brain damage with ultrafiltration and biosensor technology.

Continuous monitoring of arterio -venous glucose and lactate differences may serve as a diagnostic tool to assess normal brain function and brain pathology. We describe a method and some results obtained with arterio -venous measurements of glucose and lactate in the blood of the. Current concept on the management of arterio -venous management.

Arterio -venous malformations AVMs are congenital vascular malformations CVMs that result from birth defects involving the vessels of both arterial onfalomesentrico venous origins, resulting in direct communications between the different size vessels or onfalonesenterico meshwork of primitive reticular networks of dysplastic.

Arterio -venous malformations in childhood: In a series of arterio -venous malformations AVM recently published we found 33 children aged 1 to 16 years. In 28 cases, the admitting condition onfalomesetnerico hemorrhage.

For 31 AVMs total excision was possible. All children but two were followed-up by personal examination. Two were not able to work due to severe neurological deficits and seven had not been able to get into their intended occupation.

Management of a case with misdiagnosed spinal onfaoomesenterico arterio -venous fistula. Spinal dural arterio -venous fistula SDAVF is an uncommon and easily misdiagnosed vascular malformation. A year-old conducho suffered from acute paraparesis about 15 months before this study. He underwent a neurosurgical procedure for herniated discs of the cervical spine at that time but there was no relief and the symptoms worsened despite the surgery.

Neurologically, he had spastic paraparesis and decreased vibration sensation of the lower limbs. Spinal magnetic resonance imaging MRI revealed intra-medullary hyper-intensity lesion at T8 to T10 levels and tubular-like signal void structures in the corresponding posterior sub-arachnoid space. Further trans-arterial angiography through right T6 intercostal artery catheterization revealed engorged veins, thereby confirming the diagnosis of SDAVF.
