background: arteriovenous malformations are one of the most common vascular disorders of the colon. vascular disorders present as painless, high-volume rectal bleeding. case presentation: this study elucidates two rare cases of vascular disorders that are diagnosed as angiodysplasia of the left colon and cavernous hemangioma of the colon and rectum.  the chief complaint in two patients was rect...

INTRODUCTION Pregnancy has been linked to increased rates of arteriovenous malformation rupture. This link remains a matter of debate and very few studies have addressed the management of arteriovenous malformation in pregnancy. Unruptured arteriovenous malformations in pregnant woman generally warrant conservative management due to the low rupture risk. When pregnant women present with rupture...

This study is to investigate hematuria in pregnant patients caused by renal arteriovenous malformation and to evaluate the efficacy of superselective renal angiography and embolization used for treatment of renal arteriovenous malformation. Two cases of hematuria in pregnant patients caused by renal arteriovenous malformation were enrolled. Case 1 was a 28-year-old woman with repeatedly intermi...

The relevance of assessing the lesion visual analyzer with optic disc drusen and possibility identifying concomitant pathologies, increases introduction latest diagnostic techniques.In S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, a patient, 50 years old, complaining episodic blurred vision. diagnosis revealed nerve head congenital neurological pathology. patient was consulted...

BACKGROUND Intracranial arteriovenous malformation rarely causes pulmonary hypertension and congestive heart failure in the newborn. Its diagnosis is challenging because cardiomegaly may suggest an intra-cardiac structural lesion. CASE PRESENTATION We present two newborns, one 2-day-old male and the other 11-day-old female, with intracranial arteriovenous malformation and misdiagnosis of cong...

An arteriovenous malformation is an anomaly of capillary development that results in a direct connection between branches of an artery and veins, with no intervening capillary network. Vascular malformations of the mediastinum presenting as mediastinal masses are very rare. We report a histologically proven case of a posterior mediastinal arteriovenous malformation in a 42-year-old man that was...

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 ...

INTRODUCTION Auricular Arteriovenous Malformation of the external ear is a rarely encountered disease; in particular, arteriovenous malformation arising from the auricle, with spontaneous bleeding, has seldom been reported. OBJECTIVE In the current study, we report an unusual case of late-onset auricular arteriovenous malformation originating from the posterior auricular artery that was confi...

Pulmonary arteriovenous malformations are rare congenital abnormal connections between the pulmonary arteries and veins. The patients are usually asymptomatic [1]. Although their aetiology is unclear, it is presumed that genetic abnormalities constitute a predisposition [1, 2]. An arteriovenous malformation might cause serious complications if it remains undiagnosed and untreated [3]. We report...

background traditional digital subtraction angiography (dsa) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (avm) and dural arteriovenous fistulas (davf). objectives the aim of this study was to analyze different less invasive magnetic resonance angiography (mra) images, time-resolved mra (tr-mra) and three-dimensional ti...
