vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...

purpose : to report clinical and pathologic result of a young patient with isolated cavernous hemangioma of conjunctiva case report : a 26-year-old man who presented with smooth, red, lobular surface mass was seen in the bulbar conjunctiva in temporal side with engorged episcleral and conjunctival vessels around the lesion. excisional biopsy was performed. pathologist confirmed the diagnosis of...

in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...

We combine two near-infrared diffuse optical techniques to study variations of blood flow, haemoglobin concentration, and blood oxygen saturation in the functioning rat brain. Diffuse correlation spectroscopy (or flowmetry) monitors changes in the cerebral blood flow, without the use of the principles of tracer clearance, by measuring the optical phase-shifts caused by moving blood cells. Near-...

Congenital anomalies of the inferior vena cava (IVC) are rare but important problems in living donors for kidney transplantation, especially in cases of a short left renal vein and accompanying vascular and urological anatomic variations. However, the clinical impacts of IVC anomalies in deceased donors have yet to be reported. The unexpected presence of an IVC in an unusual position poses chal...

Vascular variations and the accidental cutting of veins and arteries potentially create problems during surgery and medical treatment. The surgeon's awareness of a vascular variation in the kidneys is essential during renal surgery and transplantation, color Doppler imaging, gonadal surgery and in the presence of an abdominal aortic aneurism. This awareness can improve the patient's recovery pr...

To test the hypothesis that temporal variations in microvessel red cell flux cause unstable oxygen levels in tumor interstitium, extravascular oxygenation of R3230Ac mammary tumors grown in skin-fold window chambers was measured using recessed tip polarographic microelectrodes. Red cell fluxes in microvessels surrounding pO2 measurement locations were measured using fluorescently labeled red ce...

In this study a new minimum lumped electrical model of total circulatory system through numerical solutions to approximate the response of the human circulatory system was presented. Among five existent ventricular elastances as activity function of heart pumps, a more accurate model was chosen as well as the operation of baroreflex system to accommodate variations in heart rate and systemic va...

hemangioma of the ovary is reported in a 66 years old woman. vascular tumors of the female genital tract are rare, especially those of the ovaiy. most cases are discovered incidentally. the case presented here was missed clinically.

background major vascular injury during a spinal surgery is a rare but most dreaded complication. case presentation a 39 years old female undergoing microscopic lumbar discectomy suddenly developed severe hypotension on table. the procedure was abandoned and the patient turned supine. it was diagnosed to be a major vessel tear and the patient was taken up for immediate successful vascular repai...
