INTRODUCTION AND OBJECTIVES: Current guidelines on the treatment of blood cholesterol recommend continuous maintenance of high-intensity statin treatment in drug-eluting stent (DES)-treated patients. However, high-intensity statin treatment is frequently underused in clinical practice after stabilization of DES-treated patients. Currently, the impact of continuous high-intensity statin treatment on the incidence of late adverse events in these patients is unknown. We investigated whether high-intensity statin treatment reduces late adverse events in clinically stable patients on aspirin monotherapy 12 months after DES implantation...

CONTEXT: With increasing use of direct oral anticoagulants (DOACs), urgent reversal of these agents becomes a growing concern. Idarucizumab is a humanized monoclonal antibody fragment that specifically binds to dabigatran with higher affinity than thrombin, rapidly neutralizing its anticoagulant effect without increased risk of thrombosis. CASE DETAILS: We describe two cases in which the recommended dose of idarucizumab was unsuccessful in completely reversing the anticoagulant effects of dabigatran...

Pheochromocytoma associated with inferior vena cava (IVC) thrombosis is very rare. A 27-year-old female presented with right flank pain and hypertensive urgency. Contrast-enhanced CT abdomen and gadolinium-contrast MRI abdomen revealed right adrenal mass suspicious of malignancy with invasion and compression to the right IVC wall along with IVC thrombus extending from the level of renal veins to the level of confluence with hepatic veins. Her routine laboratory investigations including 24-hour urine fractionated metanephrines, vanillylmandelic acid, and cortisol were normal...

BACKGROUND: Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). METHODS: We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016...

BACKGROUND: Surgical thrombectomy in the context of acute renal vein thrombosis (RVT) post-transplantation has had limited success, with considerable variation in the surgical techniques used. Unfortunately, it is usually followed by allograft nephrectomy within a few days if rapid allograft recovery does not ensue. We report a case of acute RVT in which nephrectomy was not performed despite a prolonged requirement for dialysis post-thrombectomy, but with recovery of renal function 2 weeks later...

INTRODUCTION/OBJECTIVES: Nutcracker syndrome, caused by mesoaortic compression of the left renal vein leading to symptoms related to venous hypertension, is an uncommon entity that may require operative intervention. Traditional open transposition of the left renal vein to the vena cava has been shown to have a re-intervention rate of up to 30%, while also having additional morbidity associated with laparotomy. More recently, endovascular stenting has been described in several small series, but have reported stent fracture, thrombosis and migration...

PURPOSE: To examine the influence of device positioning and infrarenal neck diameter on flow patterns in the Nellix endovascular aneurysm sealing (EVAS) system. METHODS: The transition of the aortic flow lumen into two 10-mm-diameter stents after EVAS creates a mismatched area. Flow recirculation may affect local wall shear stress (WSS) profiles and residence time associated with atherosclerosis and thrombosis. To examine these issues, 7 abdominal aortic aneurysm flow phantoms were created, including 3 unstented controls and 3 stented models with infrarenal neck diameters of 24, 28, and 32 mm...

BACKGROUND: Peripherally inserted central catheters (PICCs) can lead to development of venous thrombosis and/or stenosis. The presence of venous thrombosis and/or stenosis may preclude children with chronic medical conditions from receiving lifesaving therapies, from hemodialysis in end-stage renal disease to total parenteral nutrition in short bowel syndrome. Several adult studies have found an association between PICCs and venous thrombosis and/or stenosis, but none has evaluated for this association in children...

C Stelzner, N Abolmaali, U Hecker, S Schellong
Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound...

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to improve quality of life and survival rates in patients suffering from pseudomyxoma peritonei. The procedure is long and associated with significant intraoperative blood loss. As such, the anaesthetic management of patients undergoing this procedure can be challenging. The aim of this paper is to describe our perioperative management of pseudomyxoma peritonei patients who received CRS and to report a retrospective audit of our outcomes and complications over a six-year period at a large tertiary centre...

There is a paucity of data on the rate of urological and vascular complications in very young children after kidney transplant. We conducted a study on the incidence and risk factors for early post-transplant surgical complications in young recipients (<5 years) over three decades. The primary outcome was any urological or vascular complication within 30 days of transplant, and the secondary outcome was incidence rate of graft failure reported as per 1000 person-years. Risk factors associated with surgical complications were analyzed by logistic regression...

Renal infarction is a rare clinical entity that is not easily detected by low-sensitivity ultrasound. We herein report a case of dermatomyositis with renal infarction detected during corticosteroid therapy. The patient was followed up for 18 months. A woman who was clinically diagnosed with dermatomyositis complained of severe pain in the right flank of the low back and abdomen, accompanied by nausea and vomiting during corticosteroid therapy. Based on the findings of routine blood tests, abdominal X-ray radiography, and abdominal ultrasound, the patient was diagnosed with acute gastroenteritis and treated with levofloxacin...

Patients receiving extracorporeal membrane oxygenation (ECMO) are at risk of circuit thrombosis due to constant contact between blood and the extracorporeal components. Unfractionated heparin has traditionally been used in this setting as a systemic form of anticoagulation to prevent thrombosis of the circuit. However, if a patient develops heparin-induced thrombocytopenia (HIT), an alternative anticoagulant would be required while the patient is maintained on ECMO. Unfortunately, the pharmacokinetic changes induced by ECMO and critical illness may potentially affect optimal drug dosing...

Thrombosis is a frequent cause of morbidity and mortality in patients with nephrotic syndrome (NS). Though venous thromboses are common in NS, arterial thromboses are relatively rare. Commonly involved arteries include coronary, iliac, femoral, renal, cerebral, pulmonary, mesenteric, and axillary arteries, and the aorta. Arterial thromboses are associated with poor prognosis; treatment options are limited and patients may not always be amenable to treatment. We present the case of a 39-year-old female with NS who presented with thigh pain and was found to have sub-acute popliteal artery thrombosis...

Atypical hemolytic uremic syndrome (aHUS) is a disease characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia and acute kidney injury. The histopathologic lesions of aHUS include thrombotic microangiopathy involving the glomerular capillaries and thrombosis involving arterioles or interlobar arteries. Extra-renal manifestations occur in up to 20% of patients. The majority of aHUS is caused by complement system defects impairing ordinary regulatory mechanisms. Activating events therefore lead to unbridled, ongoing complement activity producing widespread endothelial injury...

BACKGROUND: Organ transplantation into sensitized patients with preexisting donor-specific antibodies (DSA) is very challenging. Spleen tyrosine kinase (Syk) promotes leukocyte recruitment and activation via signalling through various cell surface receptors. We investigated whether a selective Syk inhibitor (GS-492429) could suppress antibody-mediated rejection (AMR) in a rat model of AMR in sensitized recipients. METHODS: Recipient Lewis rats (RT1) were immunized with donor (Dark Agouti, RT1) spleen cells (day -5)...

Despite systemic thromboembolic complications being frequent, portal vein thrombosis is a rare complication of nephrotic syndrome. We report here a liver transplant recipient who presented a late extensive portal vein thrombosis related to nephrotic syndrome. During regular follow-up after liver transplant, the patient presented with diabetes, arterial hypertension, hypercholesterolemia, and progressive renal dysfunction. In addition, urine analysis showed isolated proteinuria, and the diagnosis of nephrotic syndrome was made 36 months after liver transplant...

End-stage kidney disease (ESKD) is one of the most prevalent diseases in the world with significant morbidity and mortality. Current modes of renal replacement therapy include dialysis and renal transplantation. Although dialysis is an acceptable mode of renal replacement therapy, it does have its shortcomings, which include poorer life expectancy compared with renal transplantation, risk of infections and vascular thrombosis, lack of vascular access and absence of biosynthetic functions of the kidney. Renal transplantation, in contrast, is the preferred option of renal replacement therapy, with improved morbidity and mortality rates and quality of life, compared with dialysis...
