Diabetic patients have a high rate of vein graft failure due to attrition or vessel occlusion that cause recurrent ischemic events or vein graft. Veins grafted into a high-pressure arterial environment must undergo vascular remodeling to better handle the altered hemodynamics and intravascular increased pressure. Multiple cellular and molecular events are purported to be associated with vascular remodeling of veins. Understanding the effect diabetes has on vascular mechano-transductive response is critical to decreasing graft failure rates...

Clinical trials in patients with macular edema due to diabetic retinopathy or retinal vein occlusion (RVO) have shown that suppression of VEGF not only improves macular edema, but also reopens closed retinal vessels, prevents progression of vessel closure, and improves retinopathy. In this study, we show the molecular basis for those clinical observations. Increased retinal levels of VEGF in mice cause plugging of retinal vessels with leukocytes, vessel closure, and hypoxia. Suppression of VEGF reduces leukocyte plugging, causing reperfusion of closed vessels...

The value of ICT is important in diagnosis of the diseases of the eye and orbit Methods for direct measurement of intracranial pressure (ICT) are exact, but they are invasive and there is some risk of infection and damage of the tissue. Currently there are 2 valid indirect methods of mesurement of IKT. Digital Ophthalmodynamometry (D-ODM) and Transcranial Doppler ultrasonography (TDU). D-ODM is a non-invasive method for measuring of the Pulsating Venous Pressure (VPT). We can measure VPT by the pulse phenomena...

BACKGROUND: A minimum future liver remnant (FLR) of 30% is required to avoid post hepatectomy liver failure (PHLF). Portal vein occlusion (PVO) is the main strategy to induce hypertrophy of the FLR, but some patients will not reach sufficient FLR hypertrophy to enable resection. Recently ALPPS has emerged as a "Salvage Procedure" for PVO failure. The aim of this study was to report the short term outcomes of ALPPS following PVO failure. METHODS: A retrospective analysis of patients enrolled within the international ALPPS Registry between October 2012 and November 2015 (NCT01924741) was performed...

Retinal venous occlusions comprise central retinal vein occlusion, hemiretinal vein occlusions, and branch retinal vein occlusions. They are associated with arterial hypertension and glaucoma. Retinal vein occlusions occur more frequently in males, at a median age of 55. The pathogenesis of retinal venous occlusions remains obscure. The clinical presentation of the disease is variable. In most cases, there is a unilateral visual loss over days with a painless, white and quiet eye. However, retinal venous occlusions may also present as an abrupt and profound loss of vision, or be asymptomatic...

PURPOSE OF REVIEW: Although cataract surgery can effectively restore visual function in many patients with cataract, pseudophakic cystoid macular edema (PCME) remains an important cause of suboptimal visual acuity. The present review provides an overview of the current literature on the prevention and treatment of PCME. RECENT FINDINGS: Optimal prevention of PCME starts preoperatively with a personalized risk assessment. Diabetes mellitus, retinal vein occlusion, epiretinal membrane, macular hole, and uveitis are the most important risk factors for developing cystoid macular edema after cataract surgery...

Phlegmasia cerulea dolens (PCD) is a rare condition resulting from venous occlusion that impairs arterial flow. We report a rare case of post-traumatic PCD after ligation of the iliac vein with successful treatment by right-to-left femoral vein to femoral vein bypass using left great saphenous vein (Palma procedure). The clinical presentation, diagnostic process, and approach to management along with a literature review on the operative management of PCD are presented in this case report.

REVIEW
Teruyo Kida
Retinal vein occlusion (RVO) is a common vascular disease of retina; however, the pathomechanism leading to RVO is not yet clear. In general, increasing age, hypertension, arteriosclerosis, diabetes mellitus, dyslipidemia, cardiovascular disorder, and cerebral stroke are systemic risk factors of RVO. However, RVO often occur in the unilateral eye and sometimes develop in young subjects who have no arteriosclerosis. In addition, RVO show different variations on the degrees of severity; some RVO are resolved without any treatment and others develop vision-threatening complications such as macular edema, combined retinal artery occlusion, vitreous hemorrhage, and glaucoma...
