vascular endothelial growth factor (vegf) is a multifunctional cytokine with distinct functions in angiogenesis, lymphangiogenesis, vascular permeability, and hematopoiesis. vegf is a highly conserved, disulfide-bonded dimeric glycoprotein of 34 to 45 kda produced by several cell types including fibroblasts, neutrophils, endothelial cells, and peripheral blood mononuclear cells, particularly t ...

purpose : to determine the association between retinal vascular diameter and its branching angles with diabetic retinopathy (dr) stages in diabetic patients methods : a descriptive analytic cross-sectional study was conducted in 62 diabetic patients (120 eyes) referred to farabi eye hospital between june 2008 and december 2009. digital fundus photography pictures were imported into photoshop so...

An association of pancreatic cancer and median arcuate ligament syndrome (MALS) is a rare and challenging situation in terms of treatment. A 60-year-old man diagnosed with pancreatic cancer underwent laparotomy. A pancreaticoduodenectomy was planned, but during the resection part of the operation, a celiac artery stenosis was noticed. The patient was diagnosed with MALS causing almost total cel...

OBJECTIVE To evaluate the results of vascular reconstruction in soft tissue sarcoma surgery and establish an algorithm based on current evidence. MATERIAL AND METHODS We studied patients undergoing soft-tissue sarcoma in a tertiary hospital. A retrospective review of 8 cases was carried out, analysing the demographics, surgical planning, complications, disease-free survival and bypass patency...

OBJECTIVES To evaluate the prevalence of a vascular network adjacent to the insertion of the pes anserinus, so that it could be used as an anatomical reference point to facilitate harvesting flexor grafts for arthroscopic reconstruction of the anterior cruciate ligament (ACL). METHODS Thirty patients with ACL tears who were going to undergo ACL reconstruction using the tendons of the semitend...

Supracondylar humerus fractures (SHF) are seen more than half of all fractures in the elbow. SHF may cause to vascular and neurologic injury. The most causes of the vascular injury are thrombosis with intimal tear, brachial artery entrapment in the fracture site, compression of the artery due to deformity/swelling and partial or complete transection of the artery (by the perforating spike of th...

variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

A knowledge of the variations of renal vascular anatomy has importance in exploration and treatment of renal trauma, renal transplantation, renovascular hypertension, renal artery embolization, angioplasty or vascular reconstruction for congenital and acquired lesions, surgery for abdominal aortic aneurysm and conservative or radical renal surgery (Sampaio & Aragão,1990; Satyapal et al., 1999; ...
