Wünderlich syndrome is a rare entity characterised by spontaneous retroperitoneal haemorrhage with renal origin. We present a case of Wünderlich syndrome secondary to clotting dyscrasia in a 64-year-old woman. The patient experienced a second Wünderlich haemorrhagic event with metachronous pseudoaneurysm formation, which was likely secondary to the large subcapsular haematoma stripping the renal capsule and tearing the cortical arteries. Selective pseudoaneurysm embolisations were successfully performed on both occasions...

BACKGROUND: Mastery of microsurgical anastomosis is key to achieving good outcomes in cerebrovascular bypass procedures. Animal models (especially rodents) provide an optimal pre-clinical bypass training platform. However, the existing models for practicing different anastomosis configurations have several limitations. OBJECTIVE: We sought to optimize the use of the rat's abdominal aorta and common iliac arteries (CIA) for practicing the 3 main anastomosis configurations commonly used in cerebrovascular surgery...

BACKGROUND AND AIMS: The pathogenic events responsible for the reduction of endothelial progenitor cell (EPC) number and function seen in patients with chronic renal failure (CRF) are poorly understood. Here we investigate the hypothesis that increased concentrations of urea associated with CRF increase ROS production directly in EPCs, causing abnormalities associated with coronary artery disease risk. METHODS: Human EPCs were isolated from peripheral blood mononuclear cells of healthy donors and cultured in the presence or absence of 20 mmol/L urea...

The SCHEDULE trial was a 12-month, randomized, open-label, parallel-group trial that compared everolimus (EVR; n=56) to conventional CsA (n=59) immunosuppression. Previously, we reported that EVR outperformed CsA in improving renal function and coronary artery vasculopathy, despite a higher rejection rate with EVR. The present study aimed to compare the effects of these treatments on quality of life (QoL). Within 5 postoperative days, patients (mean age 50±13 years, 27% women) were randomized to EVR or a standard CsA dosage (CsA group)...

OBJECTIVES: Haemodynamically stable patients admitted for coronary artery bypass grafting in acute myocardial infarction often undergo delayed surgery in order to avoid the risks of emergency surgery. However, initially stable patients undergoing delayed surgery may develop low cardiac output syndrome (LCOS) during the waiting period, which might be a major drawback of this strategy. We aim to define risk factors and clinical consequences of LCOS during the waiting period. METHODS: A total of 530 consecutive patients with acute myocardial infarction (33% non-ST-segment elevation myocardial infarction and 67% ST-segment-elevation myocardial infarction) underwent isolated coronary artery bypass grafting between 2008 and 2013...

Background The aim of the study was to assess the value of post-operative cardiac troponin T-levels, measured with a new highly sensitive assay (hs-cTnT), as a suitable parameter to predict patients' outcome after cardiac surgery. With the introduction of the new hs-cTnT assay the correlation between measured levels and the post-operative patient's outcome remains to be evaluated. Methods Patients undergoing coronary artery bypass grafting (n = 213) were included. Perioperative measurements of hs-cTnT and CK-MB were correlated to parameters of clinical outcome and further explored...

BACKGROUND: High dietary salt, as well as renal mass reduction, is known to decrease baroreflex sensitivity in rats. However, the effect of high salt intake on baroreflex sensitivity is unknown in reduced renal mass (RRM) hypertension; therefore, the aim of this study was to investigate the effects of salt loading on arterial baroreflex sensitivity and mean arterial pressure (MAP) in RRM hypertension. METHODS: Both RRM and sham-operated control (SO) rats were loaded with 0...

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...

OBJECTIVE: Hepatopulmonary syndrome (HPS) is characterized by hypoxia in patients with chronic liver disease. The mechanism of HPS includes pulmonary vasodilatation, inflammation, and angiogenesis. Prostaglandins synthesized by cyclooxygenases (COX) participate in vascular responsiveness, inflammation and angiogenesis, which can be modulated by COX inhibitors. We therefore evaluated the impact of COX inhibition in rats with common bile duct ligation (CBDL)-induced liver cirrhosis and HPS...

BACKGROUND: Abdominal aortic aneurysm surgery with suprarenal cross-clamping is often associated with renal injury. Although the mechanism underlying such injury is unclear, tissue ischemia and reperfusion, which induces endothelial dysfunction and decreases the availability of tetrahydrobiopterin (BH4), may play a role. We evaluated whether BH4 administration prevents renal ischemia/reperfusion injury in an animal model of aortic cross-clamping. METHODS: Nineteen anesthetized, mechanically ventilated, and invasively monitored adult sheep were randomized into 3 groups: sham animals (n = 5) that underwent surgical preparation but no aortic clamping; an ischemia/reperfusion group (n = 7), where the aorta was clamped above the renal arteries for 1 hour, and a BH4 group (n = 7), in which animals received 20 mg/kg of BH4 followed by aortic cross-clamp for 1 hour...

BACKGROUND: Diabetes mellitus is a major risk factor for prolonged hospital stays, renal failure, and mortality in patients having coronary artery bypass grafting (CABG). Complications pose a serious threat to patients and prolong intensive care and hospital stays. Low glomerular filtration rate (GFR) due to existing renal impairment or volume depletion may exacerbate acute renal impairment/failure in these patients. Preoperative volume replacement therapy (VRT) is reported to increase the GFR and we hypothesize that VRT will reduce renal impairment and related complications in diabetic patients...

In the kidneys, there is both blood flow through the capillaries and flow of pre-urine through the tubuli and collecting ducts. We hypothesized that diffusion-weighted (DW) MRI measures both blood and pre-urine flow when using a tri-exponential intravoxel incoherent motion (IVIM) model. Our aim was to systematically investigate and optimize tri-exponential IVIM-analysis for the kidney and test its sensitivity to renal perfusion changes in humans. The tri-exponential fit probes the diffusion coefficient (D), the intermediate (D*i) and fast (D*f) pseudo-diffusion coefficients, and their signal fractions, fD, fi and ff...
