The extended posterior approach for resection of sacral tumours
ConclusionThe reported technique allowsen bloc resection of sacral tumours up to S1, through a posterior-only approach. It is less invasive with minimal morbidity. The functional and oncological outcomes are similar to those reported by other investigators.Graphical abstractThese slides can be retrieved from electronic supplementary material.
CONCLUSIONS: LS could reduce serum YKL-40 levels and PVT progression and was a useful treatment for patients
Authors: Ilias I, Thomopoulos C Abstract Introduction: Pheochromocytomas/paragangliomas (PPG) are rare tumors. In theory the diagnosis of PPG should be straightforward. In clinical practice, however, considerable delays are noted in establishing such a diagnosis. Areas covered: We assess the characteristics of various approaches to diagnosis and localization of PPG lesions (and their relevant caveats). We also evaluate potential biases to diagnosis. Expert opinion: A high degree of suspicion - particularly in younger patients - is required by clinicians. The availability of diagnostic means (mainly of biochemical t...
Conclusions and ImplicationsWe have shown that the pharmacometabonomics technique was able to differentiate between unstable and stable INR with good accuracy. NMR-based pharmacometabonomics has the potential to identify novel biomarkers in plasma, which can be useful in individualizing treatment and controlling warfarin side effects, thus, minimizing undesirable effects in the future.
ConclusionsEndoscopic imaging of the venous system has great potential to improve access and to guide endovenous interventions. Chronic venous occlusion in post-thrombotic syndrome is a fibrotic process, and chronic venous fibrosis is a better description of the type of occlusion and should replace chronic venous thrombosis.
ConclusionsPostural changes dramatically affect CSA of the LCIV and LRV and thus the degree of stenosis in women diagnosed with PVD. Stenosis found in patients while supine often disappears when the position is changed to lying on the left side or to standing. Therapeutic decisions based on assessment of CSA reduction in the supine position are likely to be inadequate.
ConclusionPortomesenteric venous thrombosis is an uncommon yet potentially fatal complication of bariatric surgery. A high index of suspicion, early diagnosis and subsequent adequate management is required. Based on this case series and the potential risk of portomesenteric venous thrombosis, we altered our clinical practice to include a 1 week course of low molecular weight heparin to be administered to all patients after discharge.
The objectives of this study were to characterize the kinetics of thrombus resolution and to define an appropriate duration of anticoagulation and interval for surveillance US.
Current arteriovenous grafts (AVGs) have unacceptably high failure rates. This issue led to the development of tissue-engineered vascular grafts in an attempt to mimic a native blood vessel. We hypothesized that a novel synthetic vascular graft could be developed using electrospinning technology that functions as scaffolding for cell ingrowth, thereby providing the added natural protection of native cells against thrombosis and infection. The resulting graft would also maintain the strength, kink resistance, and safety with cannulation that standard synthetic AVGs provide.
The radiocephalic arteriovenous fistula (AVF) is the preferred standard for patients needing primary hemodialysis access creation. In patients who lack suitable superficial veins in the distal upper extremity, proximal native vessels or synthetic grafts are often used. However, proximal primary access creation results in loss of vascular territory for future interventions, and grafts and proximal vessels have been shown to be inferior starting points because of higher risk of infection, thrombosis, and steal syndrome.
