Vein of Galen aneurysmal malformations (VGAM) are characterized by multiple arteriovenous connections draining into a markedly enlarged median draining vein. This ectatic vein is not the vein of Galen, but its embryonic precursor, the median prosencephalic vein of Markowski. During normal development, the posterior portion of the median prosencephalic vein persists as the vein of Galen, while i...
background: peripheral vascular injury associated with lower limb trauma is a well-known emergency. the experience for the management of popliteal artery trauma have mainly come from managing the traumas of military personnels during iran-iraq war. the present study compared the effects of two currently-used surgical techniques in the management of popliteal trauma, namley femoropopliteal bypas...
Background: Central venous catheters are useful instruments in monitoring of critical patients and are important roots for total parentral nutrition. The catheters are widely used in general wards and intensive care units. Their use may be associated with serious and rare complications.Case presentation: We reported a 24 years old woman that admitted to Ghaem hospital Mashhad University of Medi...
Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral sof...
We report our experience with an ultrasound system to measure esophageal varix pressure in an in vitro model. The ultrasound system consists of a 12.5 MHz frequency intraluminal ultrasound probe, a water infusion catheter, and a manometry catheter, all contained within a nondistensible latex bag. Esophagi and external jugular veins were harvested from five pigs. The vein and ultrasound system w...
AIMS Failure of vein graft conduits due to vein graft thickening, accelerated atherosclerosis, and subsequent plaque rupture is applicable to 50% of all vein grafts within 10 years. New potential therapeutic targets to treat vein graft disease may be found in components of the innate immune system, such as mast cells and complement factors, which are known to be involved in atherosclerosis and ...
OBJECTIVES Retrospective analysis of five cases of coronary vein balloon angioplasty performed to allow insertion of left ventricular pacing leads. BACKGROUND Coronary vein stenoses or an insufficient vessel caliber can preclude transvenous placement of coronary vein leads. METHODS We compared our total patient population (n = 218), in whom we implanted coronary vein leads, to those five pa...
Introduction: Retinal vein occlusion is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO). Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...
