A girl aged 11 years and 3 months with occlusion of the inferior vena cava had experienced two renal transplant graft failures since birth. The third renal transplant from a live donor was carried out. Preoperative evaluation showed that the arteries from the right common to the right external iliac artery were absent, and the ilio-caval vein was occluded below the level of the renal vein. The donor's renal artery was anastomosed to the aorta. The donor's ovarian and large saphenous veins were used to extend the transplant renal vein to the recipient's patent inferior vena cava...

PURPOSE: Retinal vein occlusion (RVO) is an important cause of visual disability in the modern world. We aim to evaluate the real-world outcomes of patients with RVO treated with anti-vascular endothelial growth factor (VEGF) in Portugal. METHODS: We performed a retrospective, observational, multicenter study including 8 centers across Portugal and 200 patients treated with either ranibizumab or bevacizumab. Data were collected at 3 time points: time of diagnosis (0 time point) and 6 and 12 months after initiating treatment...

BACKGROUND: Neovascular glaucoma (NVG) is rare, comprising only 3.9% of all glaucoma cases. The most common cause of NVG is ischaemic central retinal vein occlusion (iCRVO). NVG frequently results in blindness and painful end-stage glaucomatous damage leading to the need for enucleation. Currently, there is no preventive therapy for NVG following iCRVO. Rescue treatments have severe drawbacks. Accordingly, there is a great need for preventing the often visually devastating outcomes of NVG...

A 58-year-old man presented with slowly progressive chemosis, exophthalmos, and blepharedema of the left eye. Digital subtraction angiography revealed multiple dural arteriovenous fistulas(dAVFs)involving the bilateral tentorium, superior sagittal sinus, and right frontal convexity. In addition, occlusion of the left cavernous sinus and left sigmoid sinus were observed, which could lead to venous hypertension and might be associated with the occurrence of multiple dAVFs. Along with the congestion of the left ophthalmic vein, increased intracranial pressure due to the left tentorial dAVF with cortical venous reflux could have caused the left eye symptoms; therefore, the tentorial lesion was treated first...

While central venous stenosis is a common consequence of protracted central venous catheter use, intracardiac device transvenous leads, and central venous instrumentation, the majority of patients who develop symptomatic central venous stenosis present with characteristic venous hypertension. However, some patients may develop an abnormal intracranial venous circulation and present with neurologic symptoms. This paper will summarize findings from case reports that describe the neurologic sequelae that can develop as a result of central venous stenosis/occlusion in end-stage renal disease patients with a functional arteriovenous access...

BACKGROUND: Resection of the liver is often limited to the insufficient future liver remnant (FLR). To address this problem, the modification surgical technique "associating liver tourniquet and portal vein occlusion for staged hepatectomy" (ALTPS) was developed and led to quick hypertrophy in a short interval. In some colorectal cancer patients with multiple and bilobar metastases, the resection of the primary is often protracted immensely to the unpredictable postoperative complications for whom is to be treated with a liver-first approach...

An anterolateral thigh flap was salvaged using 110 medical leeches in the absence of an available vein for reanastomosis. After surgical construction of the flap for full-thickness thoracic wall reconstruction, the patient developed complete venous occlusion. Specifically, the anastomotic vein developed complete occlusion, and the internal jugular vein had a thrombus. In addition, because the lung was posterior to the flap, the angiogenic area of the flap was very small. When the medical leeches were first applied, the flap showed prominent venous congestion...

Hypoxia-inducible factor (HIF) is a transcription factor that facilitates cellular adaptation to hypoxia and ischemia. Long-standing evidence suggests that one isotype of HIF, HIF-1α, is involved in the pathogenesis of various solid tumors and cardiac diseases. However, the role of HIF-1α in retina remains poorly understood. HIF-1α has been recognized as neuroprotective in cerebral ischemia in the past two decades. Additionally, an increasing number of studies has shown that HIF-1α and its target genes contribute to retinal neuroprotection...

In this protocol, PAH is induced by combining a 60 mg/kg monocrotalin (MCT) injection with increased pulmonary blood flow through an aorto-caval shunt (MCT+Flow). The shunt is created by inserting an 18-G needle from the abdominal aorta into the adjacent caval vein. Increased pulmonary flow has been demonstrated as an essential trigger for a severe form of PAH with distinct phases of disease progression, characterized by early medial hypertrophy followed by neointimal lesions and the progressive occlusion of the small pulmonary vessels...

OBJECTIVE: Central venous occlusion is a common occurrence in patients with end stage renal disease. Placement of upper extremity arteriovenous access in patients with occlusion of the brachiocephalic veins is often not an option. Avoidance of lower extremity vascular access can decrease morbidity and infection. TECHNIQUE: The central venous lesions were crossed centrally via femoral access. The wire was retrieved in the neck extravascular. A HeRo catheter was then placed in the right atrium and completed with an arterial anastomosis...

The liver is a central organ in metabolism and can be affected by numerous inherited metabolic disorders. Recombinant adeno-associated virus (AAV)-based gene therapy represents a promising therapeutic approach for such diseases. AAVs have been demonstrated to be safe, and resulted in high and long-term expression in preclinical and clinical studies. However, there are still some concerns regarding the expression levels that can be achieved and the percentage of hepatocytes that can be transduced. Due to the cell-autonomous nature of most metabolic liver disorders, a high percentage of hepatocytes needs to be corrected in order to achieve a therapeutic effect...

PURPOSE: The association of central retinal vein occlusion (CRVO) with primary open-angle glaucoma (POAG) or ocular hypertension has been reported, and lowering intraocular pressure (IOP) helps to improve the retinal circulation in eyes with CRVO. However, the clinical features of CRVOs with normal-tension glaucoma (NTG) are not well known. Therefore, we investigated Japanese CRVO patients with NTG. METHODS: We retrospectively investigated 234 CRVO patients over 5 years, with follow-ups of more than 12 months, and evaluated the prevalence of glaucoma...

Patients with end-stage renal disease undergo renal transplant, peritoneal dialysis, or intermittent hemodialysis for renal replacement therapy. For hemodialysis, native fistulas or grafts are preferred but hemodialysis catheters are often necessary. Per KDOQI, the right jugular vein is the preferred vessel of access for these catheters. However, in patients with long-standing end-stage renal disease vein thrombosis, stenosis and occlusion occurs. In these patients with end-stage vascular access, unconventional routes of placement of dialysis catheters are needed...
