BACKGROUND: A cross-circulation technique involves gaining access to a cerebral vessel through a patent anterior or posterior communicating artery. This technique may be utilized in patients with emergent large vessel occlusions and an unfavorable direct route to the occlusion. While few previous reports have demonstrated successful cross-circulation technique for treatment of emergent large vessel occlusions, we present the first two cases of trans-anterior communicating artery stent-retriever thrombectomy...

PURPOSE: The knife is the most common used instrument for endoscopic urethrotomy. Unfortunately, there are high recurrence rates; it is thought that a laser reduces those rates. We compared the two techniques in this retrospective study. MATERIALS AND METHODS: Between 2010 and 2014, 127 patients were operated on with the knife (KG) and for 65 patients, the laser (LG) was used. We scored the complexity of the stricture using the UREThRAL stricture score (USS) and we scored if a treatment was successful...

Alongside imaging techniques, pulmonary function testing helps in the diagnosis of underlying disorders such as asthma and chronic obstructive pulmonary disease (COPD) or fibrosing lung disease. However, disease severity grading is also important, as well as disease follow-up under therapy. The value of spirometry as a first-line diagnostic test, whole-body plethysmography in advanced diagnostics, the measurement of transfer factor, as well as blood gas analysis are outlined. The importance of spiroergometry, echocardiography, and right-heart catheterization, particularly in the functional assessment of pulmonary vascular disorders, is described...

Successful replantation of distal digital segments necessitates the establishment of sufficient outflow to minimize congestion and progressive tissue necrosis. In cases where only arterial anastomosis is feasible, an artificial outlet must be provided to maintain physiological requirements until microvenous circulation regenerates. This can be accomplished using any number of "exsanguination techniques" designed to facilitate egress through ongoing passive blood loss. Although reportedly effective, these measures are imprecise and carry a substantial risk of infection, scarring, and/or uncontrolled hemorrhage...

It is not uncommon to see in developing and underdeveloped countries, where the anesthesiologist who is untrained in cardiac specialty takes care of cardiac catheterization centers. The service in cardiac catheterization laboratories (CCL) in developed countries and some of the developing countries is mainly provided by the cardiac anesthesiologists. The scenario is not same in some part of developing countries or in underdeveloped countries which are mainly due to increase in number of CCL (catheterization laboratory) when compared to the number of cardiac anesthesiologists working outside the operation theater...

INTRODUCTION: Lower urinary tract symptoms are common in Parkinson diseases, especially chronic urinary retention. In case of significant and symptomatic postvoid residual, a specific treatment is necessary in order to empty the bladder and nowadays the gold standard of such neurogenic bladder is based on self-intermittent-catheterizations, if possible at all. We carried out a retrospective study about feasibility and outcomes of self-intermittent-catheterizations in this population. METHODS: Retrospective study with qualitative and quantitative, clinical and instrumental (urodynamic) assessment, of lower urinary tract symptoms as urinary retention in extrapyramidal syndromes...

Neurogenic lower urinary tract dysfunction (NLTUD) is commonly encountered in neuro-rehabilitation settings and is caused by a variety of pathologies. The management of spinal cord injury (SCI) has been the model of reference for the approach to NLTUD due to many other diseases of the central and peripheral nervous system. The decline in renal-related mortality in SCI patients after the introduction of clean intermittent catheterization in association with pharmacological treatment (antimuscarinics in particular), and the algorithms proposed since 1998 by the International Consultations on Incontinence underline the need of early assessment and treatment of urinary incontinence and/or urinary retention in neuropathic patients...

INTRODUCTION: The Malone antegrade continence enema (MACE) procedure remains an effective tool in providing independence to patients with refractory constipation. Appendiceal, ileal and colonic segments are all used depending upon the patient's individual anatomy and surgeon's preference. Unfortunately, MACE stomal stenosis (SS) remains a frustrating complication. It was hypothesized that SS is associated with the type of efferent limb used for MACE construction. OBJECTIVE: To perform a retrospective risk analysis of the pre-operative factors that correlated with postoperative stomal stenosis...
