Pulmonary arteriovenous fistula is a congenital and rarely acquired anomalous direct communications between pulmonary arteries and veins. Transcatheter embolization using metallic coil or detachable balloon is one of the common treatment procedure. However, recanalization after the embolization is one of the concern and its differentiation from the retrograde filling via pulmonary vein is diffi...

This study presents and tests the clinical validity of a hemodynamic grading system that depends on noninvasive transcranial Doppler ultrasonographic parameters. The suggested transcranial Doppler-based grading system was compared with the Spetzler-Martin anatomic grading for prognosticative validity and clinical dependability. We concluded the following: (1) The pulsatility index was shown to ...

BACKGROUND Uterine arteriovenous malformation is a rare but life-threatening condition that accounts for 1-2% of massive vaginal bleeding. Uterine arteriovenous malformations are less common after menopause. The condition can be diagnosed using Doppler ultrasound, magnetic resonance imaging, computed tomography, and pelvic angiography. CASE PRESENTATION We report a postmenopausal patient with...

Arteriovenous malformations of the lower urinary tract are uncommon lesions, usually presenting as scrotal masses. A case of recurrent acute scrotal pain mimicking testicular torsion that was attributed to the presence of an arteriovenous malformation of the spermatic cord is described. To our knowledge this is the first reported case of an arteriovenous malformation of the spermatic cord prese...

We present a prepubertal male cystic fibrosis patient with high circulating oestrogen levels (as a consequence of sever cystic-fibrosis-related hepatobiliary disease) who subsequently developed a large pelvic arteriovenous malformation. This has not previously been described in patients with cystic fibrosis, despite the association between high oestrogen levels and arteriovenous malformations. ...

Arteriovenous haemofiltration was used for removal of fluid overload in a 9 month old burned infant with diuretic resistant hypervolaemia. After 60 hours of arteriovenous haemofiltration hypervolaemia had disappeared. Arteriovenous haemofiltration proved to be a safe and simple extracorporal method of managing severe fluid overload.

Congenital pulmonary arteriovenous fistulae, provided that they are not present in very large numbers, are best managed surgically, and there is no effective alternative management. Where pulmonary arteriovenous fistulae develop as a consequence of pulmonary hypertension it is rational to resect the fistulae if the cause of pulmonary hypertension - for example, mitral stenosis - is correctable....

Spinal arteriovenous fistulas are rare formations with severe clinical symptoms and consequences, if left untreated. Over the past few decades, considerable progress has been made for the clarifying and correct interpretation of these lesions by conducting selective angiographies. Good knowledge of anatomical characteristics and pathophysiology of spinal arteriovenous fistulas has led to the de...

Pulmonary arteriovenous malformations are abnormal direct communications between pulmonary arteries and pulmonary veins. Transcatheter embolotherapy is the preferred treatment method because of its less invasive nature. There are several methods for the treatment of pulmonary arteriovenous malformations, such as detachable occlusion balloon and coil embolization. The Amplatzer Vascular Plug is ...
