After extended right hepatectomy remnant liver can be affected by outflow obstruction due to torsion of the inferior vena cava or kinking of the left hepatic vein. Remnant liver fixation is therefore suggested to avoid postoperative acute Budd-Chiari syndrome. Despite remnant liver reposition during surgery, a 76-years-old woman developed complete ...

PURPOSE: Ruptured cerebral arterial aneurysms require prompt treatment by either surgical clipping or endovascular coiling. Training for these sophisticated endovascular procedures is essential and ideally performed in animals before their use in humans. Simulators and established animal models have shown drawbacks with respect to degree of reality, size of the ...

BACKGROUND AND IMPORTANCE:: Most neuroendovascular interventions rely on a transfemoral approach to the intracranial circulation; however, this is sometimes not possible due to complex aortic arch anatomy or femoral arterial disease. Transradial arteriography and intervention is well established in interventional cardiology and there have been some reports of successful neurointervention ...

We report two cases of anesthesia for radical retropubic prostatectomy (RRP) in obese-chronic obstructive pulmonary disease (COPD) patients using the combination of epidural anesthesia and non-invasive ventilation (NIV). This technique avoided intubation, general anesthesia and perioperative pulmonary complications.

BACKGROUND: Diabetic patients with multivessel coronary artery disease who undergo coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCI) are at greater risk of late morbidity and mortality than nondiabetic patients. We questioned earlier comparisons of these two approaches that showed no differences in survival rates. This study compares ...

High-resolution CT angiography (CTA) is currently available using multidetector row CT (MDCT); however, its use for small artery visualisation has been limited. To evaluate its capability, we investigated CTA visualisation for difference in number of the lenticulostriate artery (LSA) branches between normotensive and hypertensive patients, because hypertension is a major ...

Pulmonary arterial hypertension (PAH) is no longer an orphan disease. There are three different classes of drugs for the treatment of PAH that are currently being used and an increasing number of patients are being treated with a single drug or combination therapy. During the last 25 yrs, new insights ...

Pulmonary hypertension is a life-threatening condition that results from a heterogeneous group of diseases, many of which demonstrate characteristic pathologic changes of pulmonary vascular inflammation and remodeling. Recent clinical studies indicate obesity to be a risk factor for the development of pulmonary hypertension; however, the mechanisms leading to this association ...

Although annulus rupture is one of the most severe complications of TAVI, the incidence and mechanism of this complication remain unclear. Out of 387 consecutive TAVI cases in our institution, the incidence of annulus rupture was 1.0% (4/387). The first two patients died because of hemodynamic collapse due to tamponade ...

Aims: Acute coronary syndromes (ACS) are often caused by rupture of non-flow limiting "vulnerable" atherosclerotic plaque, characterised by a large necrotic core pool and a thin, inflamed fibrous cap that are unidentifiable with diagnostic coronary angiography. The implementation of novel invasive imaging modalities, such as intravascular ultrasound-virtual histology (IVUS-VH) and ...

Pulmonary artery haemorrhage is thankfully a very rare complication following pulmonary artery catheter insertion. It carries a significant mortality of 50%, and most cases are managed conservatively or with embolization therapy. We present an occult case, in which a patient presented with haemodynamic compromise without haemoptysis or significant haemothorax, who ...

Pulmonary Arterial Hypertension is a rare and devastating disease characterized by vascular proliferation and remodeling. Epoprostenol, the drug counterpart of the eicosanoid prostacyclin produced by the vascular endothelial cells, is the drug of choice for this disease. Its capacity to act rapidly and significantly improve survival prospects in severe Pulmonary ...

Pulmonary tumor thrombotic microangiopathy (PTTM) is known as a rare and severe cancer-related pulmonary complication. Nowadays, fewer than 80 cases have been reported in the literature and very few cases have been diagnosed antemortem. We describe an autopsy case of PTTM associated with cancer of unknown origin. A 56-year-old male ...

Surgical aortic valve replacement (SAVR) has long been the mainstay of therapy for severe aortic stenosis. However, transcatheter aortic valve replacement (TAVR) is now generally accepted as the new standard of care for patients with symptomatic aortic stenosis who are not candidates for open surgery. Arguably TAVR may also be ...

Central venous catheters are extensively used in patients with cancer to secure delivery of chemotherapy and facilitate phlebotomy. Unfortunately, considerable morbidity can result from early complications or late sequelae, ranging from arterial puncture, pneumothorax, bloodstream infections, to catheter-related thrombosis (CRT). Contemporary studies have shown that the incidence of symptomatic CRT ...

OBJECTIVES: It is currently unclear whether the parallels between abdominal aortic aneurysms (AAAs) and chronic obstructive pulmonary disease (COPD) are explained by common risk factors alone, such as cigarette smoking, or by a predetermined cause. Given the persistent controversy with regard to the association between AAA and COPD, we studied ...

Conventional revascularization of the lower extremities secondary to aortoiliac atherosclerotic vascular disease (ASVD) involves major intra-abdominal surgery with aortobifemoral bypass grafting. Complication rates are as high as 10% and perioperative mortality can be as high as 5%; therefore, careful patient selection is paramount. Endovascular aortobifemoral bypass repair with aortic bifurcation ...

Although chronic obstructive pulmonary disease (COPD) is a major cause of disability worldwide, its determinants remain poorly defined. We hypothesized that both pulmonary and extra-pulmonary factors would predict prospective disablement across a hierarchy of activities in persons with COPD. Six hundred and nine participants were studied at baseline (T0) and ...
