Manohar, Murli, and Thomas E. Goetz. Intrapulmonary arteriovenous shunts of 15 m in diameter probably do not contribute to arterial hypoxemia in maximally exercising Thoroughbred horses. J Appl Physiol 99: 224–229, 2005. First published March 17, 2005; doi:10.1152/japplphysiol.01230.2004.—The present study examined whether Thoroughbred horses performing strenuous exercise exhibit intrapulmonary...

Background. Arteriovenous malformations of the brain are a rare vascular pathology. Many studies focus on features venous drainage arteriovenous malformations. The angioarchitectural and hemodynamic component can influence patient management. Objective . To evaluate relationship between types clinical course. Design methods. Survey included 61 adult patients neurosurgical department № 3 Polenov...

Pial arteriovenous fistulas are an unusual type of cerebrovascular lesion. The vascular supply of this type of injury comes from cortical and pial vessels which are not located in the dura leaflets. With the aim to make a grading scale for this type of injury, we conducted a literature search using the keywords "pial arteriovenous fistulas", "embolization" associated with "outcome". Angiographi...

BACKGROUND Hemangioma is the most common tumor of neonatal period and it is almost always appeared by the end of the first week of life and can be found mostly in head and neck area. This study evaluated the synergistic effect of bleomycin, triamcinolone and epinephrine in treatment of hemangioma and arteriovenous malformations. METHODS In this multicenter study, a combination of bleomycin, t...

Arteriovenous malformations have a wide range of clinical presentations and an unfortunately unpredictable response to both nonsurgical and surgical intervention. The authors report on the surgical treatment of a 19-year-old man with a complex lower extremity arteriovenous malformation, previously unsuccessfully treated with numerous local sclerotherapy and interventional radiology embolization...

We present the first case of an arteriovenous fistula after an all-inside anterior cruciate ligament (ACL) reconstruction. A seventeen-year-old boy had an uneventful ACL reconstruction. Four weeks after surgery, the patient was seen with a pulsating swelling at the lateral distal upper leg. Vascular consultation led to the diagnosis of pseudoaneurysm and arteriovenous fistula of the lateral sup...

Aqueous outflow via the conventional outflow pathway is dependent on the pressure gradient between intraocular pressure (IOP) and episcleral venous pressure (EVP). Elevated IOP resulting from increased EVP is a well-known complication of arteriovenous fistulas, which are usually between the carotid artery and the cavernous sinus. Arteriovenous malformations usually occur spontaneously, after a ...

Vascular anomalies are a heterogeneous group of congenital blood vessel disorders more typically referred to as birthmarks. Subcategorized into vascular tumors and malformations, each anomaly is characterized by specific morphology, pathophysiology, clinical behavior, and management approach. Hemangiomas are the most common vascular tumors. Lymphatic, capillary, venous, and arteriovenous malfor...

Congenital arteriovenous communications involving the external carotid artery and jugular veins are rare. We report a 4-year-old girl with a history of an abnormal audible sound in the right ear during sleep. Physical examination revealed a carotid bruit, thrill and a pulsatile mass in the right neck. A simple congenital right external carotid-jugular arteriovenous fistula was confirmed and suc...

Facial palsy after embolization of neck arteriovenous fistula is an extremely rare complication. In our case, complete facial palsy occurred after embolization and was successfully treated with superficial parotidectomy, vessel ligation, and plug removal. We report the first case of unusual facial palsy that developed 13 days after neck arteriovenous fistula embolization. As a result of our fin...
