OBJECTIVE: Peripheral venous reconstruction surgery may be necessary for appropriate oncologic resection; however, the operative approach and surgical outcomes are not well described. We report our experience with these complex reconstructions to identify best practice. METHODS: We retrospectively reviewed all adult patients who underwent peripheral vein reconstruction for tumor resection at Mayo Clinic, Rochester (2000-2015). Patients were classified into three subgroups by the location: iliac (IL), lower extremity (LE), and upper extremity (UE)...

Scope A systematic review of the clinical literature concerning medical management of chronic venous disease with the venoactive therapy Micronized Purified Flavonoid Fraction was conducted in addition to an investigation of the hemodynamics and mechanism of chronic venous disease. Methods The systematic review of the literature focused on the use of Micronized Purified Flavonoid Fraction (diosmin) which has recently become available in the US, in the management of chronic venous disease. The primary goal was to assess the level of evidence of the role of Micronized Purified Flavonoid Fraction in the healing of ulcers, and secondarily on the improvement of the symptoms of chronic venous disease such as edema...

Protein C deficiency is a risk of venous thrombosis because of poor fibrinolytic activity. It remains controversial whether protein C deficiency causes arterial thrombosis. A 21-year-old woman was referred with a chief complaint of right leg pain and numbness. Contrast-enhanced computed tomography revealed a low-density mass in the left ventricle (LV), splenic infarction, and peripheral arterial obstructions in her right leg. Thrombosis extending from the renal vein to the inferior vena cava was also detected...

BACKGROUND: This study aimed to introduce an improved surgical procedure to reduce the incidence of urinary tract complications after renal transplantation in mice using a modified bladder patch-to-bladder anastomosis technique. METHODS: Renal isotransplantation was performed in 28 male C57BL/6 mice. The urinary tract was reconstructed with a ureteral anastomosis between the donor's small bladder patch and the recipient's bladder. The bladder patch was secured through a cystotomy in the recipient's bladder mucosa and seromuscular layers, which were sutured in a double-layer manner...

Foreign body ingestion is common, although perforation after ingestion is rare. We report a case of an ingested sharp wooden stick that perforated the proximal jejunum toward the renal vasculature, causing segmental renal artery thrombosis and renal infarct. The patient presented with severe abdominal pain and vomiting. A computed tomography scan revealed a linear opacity corresponding to the foreign body. The wooden stick was removed endoscopically through deep-push enteroscopy with a rat-tooth forceps. We report this unique case of perforation by a foreign body through the proximal jejunum to the left kidney, which was managed endoscopically...

BACKGROUND: Radial artery is now the most frequent access for coronary angiography and intervention. Despite the common opinion that it is safer than femoral access, it has the potential for serious complications. One of them is upper limb ischemia caused by radial artery thrombosis. CASE REPORT: We are presenting a case of critical hand ischemia after coronary angiography performed through radial access despite existing risk factors, which may be considered as relative contraindications...

BACKGROUND: The incidences of thromboembolism (TE) in neonates were reported to be around 0.51 per 10,000 live births per year for overall TE and 24 per 10,000 NICU admissions per year. As the incidences of TE in children and adults are lower in Asian populations, the incidences, risk factors, and outcomes of neonatal TE may be different to those reports from other countries. OBJECTIVES: To determine the incidences, risk factors and outcomes of neonatal TE in a tertiary care hospital in Thailand...

Thromboembolic disease is an important and frequent complication in patients with the nephrotic syndrome (NS), and the consequences are often severe. Usually, the venous system is affected. Arterial thrombosis has rarely been reported and occurs mainly in children. We report the case of a 27-year-old man with a history of NS due to focal and segmental glomerulosclerosis resistant to steroids and cyclosporine, admitted for bilateral pain in the calves. Aortogram revealed a suspended thrombus in the abdominal aorta just below the origin of the renal arteries with embolism into the left tibioperoneal trunk and the right anterior tibial artery...

OBJECTIVES: We evaluated the clinical outcomes of patients with chronic kidney disease (CKD) who underwent orbital atherectomy for severe coronary artery calcification (CAC) prior to stent implantation. BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with severe CAC is associated with increased rates of adverse clinical events. Patients with CKD are at increased risk for atherosclerotic cardiovascular disease, including vascular calcification, and have worse outcomes after PCI...

BACKGROUND: Few studies have examined the treatment and outcome of adult-onset minimal change nephrotic syndrome (MCNS). We retrospectively studied 125 patients who had MCNS with onset in either adulthood or late adolescence. Presenting characteristics, duration of initial treatment and response to treatment, relapse patterns, complications, and long-term outcome were studied. STUDY DESIGN: Case series. SETTING & PARTICIPANTS: Patients with new-onset nephrotic syndrome 16 years or older and a histologic diagnosis of MCNS in 1985 to 2011 were identified from pathology records of 10 participating centers...

Although chronic kidney disease (CKD) is strongly associated with onsets of cardiovascular disease (CVD), the pathogenic mechanism between these diseases has not been fully understood. To develop and validate new therapeutic strategies for this complication, appropriate experimental models that reflect the complexity of the underlying pathophysiology are needed. The Osborne-Mendel (OM) rat was identified as an atherosclerosis-prone and a premature-death rat strain among 16 inbred rat strains when fed high-cholesterol containing diet...

Patients with chronic kidney disease (CKD) have an increased risk of vascular disease, which is associated with considerable health care costs. Vascular disease in CKD differs clinically and pathobiologically from that in patients with normal renal function. Besides the traditional risk factors, retention of uremic toxins contributes to the pathogenesis of vascular disease in patients with CKD. Indoxyl sulfate is a protein-bound uremic toxin and is inefficiently removed by conventional dialysis. Accumulating evidence suggests that indoxyl sulfate is a vascular toxin involved in atherosclerosis, arteriosclerosis, vascular calcification and vascular repair...

Polyarteritis nodosa (PAN) is a systemic necrotising vasculitis preferentially targeting medium-sized arteries and not related with glomerulonephritis or small vessel involvement. Clinical manifestations of PAN are multisystem. The gastrointestinal, renal, cardiac, musculoskeletal, skin and central nervous systems may be involved. The aetiology remains unknown, and the ensuing vasculitis may lead to aneurysm formation and thrombosis in any organs of the body with resultant ischaemia. PAN of the intestines is a relatively common manifestation of this disease but rarely causes bowel ischaemia resulting in necrosis...

REVIEW
Aparna Dalal
Patients listed for organ transplant frequently have severe coronary artery disease (CAD), which may be treated with drug eluting stents (DES). Everolimus and zotarolimus eluting stents are commonly used. Newer generation biolimus and novolimus eluting biodegradable stents are becoming increasingly popular. Patients undergoing transplant surgery soon after the placement of DES are at increased risk of stent thrombosis (ST) in the perioperative period. Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor such as clopidogrel, prasugrel and ticagrelor is instated post stenting to decrease the incident of ST...

Sorafenib is thus far the only systemic treatment for hepatocellular carcinoma (HCC) based on the results of two randomized controlled trials performed in Western and in Eastern countries, despite a poor response rate (from 2% to 3.3%) following conventional evaluation criteria. It is now recognized that the criteria (European Association of the Study of the Liver criteria, modified response evaluation criteria in solid tumors) based on contrast enhanced techniques (computed tomography scan, magnetic resonance imaging) aimed to assess the evolution of the viable part of the tumor (hypervascularized on arterial phase) are of major interest to determine the efficacy of sorafenib and of most antiangiogenic drugs in patients with HCC...

A 76-year-old male presented with a submassive pulmonary embolism despite having an inferior vena cava (IVC) filter. Imaging demonstrated pulmonary artery emboli and a deep vein thrombosis in the left common femoral vein. Venography revealed the IVC filter with struts extending into the left and right renal veins. A new IVC filter was deployed below the prior filter. This case demonstrates IVC filter migration complicated by a submassive pulmonary embolism.

Renal artery thrombosis is a rare complication of blunt abdominal injury. It occurs most frequently in car accidents in which sudden deceleration results in multiple internal injuries. Renal artery occlusion occurs rarely as an isolated blunt trauma. This report presents a case of traumatic occlusion of the left renal artery with complete ischaemia of the left kidney in a haemodynamically stable girl who suffered multiple seat-belt injuries in a car crash. Ambiguous findings on a CT scan of the abdominal cavity indicated surgical inspection of the abdomen and, since the injury-to-surgery interval was short, an attempt at revascularisation of the left kidney was made...
