PURPOSE To evaluate the outcomes of juxtarenal aortic occlusion (JRAO), a review of 15 patients who underwent aortic bypass replacement following aortorenal thrombectomy, especially focusing on the safety of suprarenal aortic clamping or transient aortic compression, was undertaken. MATERIALS AND METHODS During the period of June 2001 to November 2012, 15 patients with JRAO (chronic 10, acute...

Sheet-metal parts produced by pressing, stamping or similar technology; usually have residual stresses, which tend to deform them. If these parts are intended to be assembled with other elements, it is necessary to perform measurements to check if constructive dimensions are within acceptable tolerance limits. Such measurements require at least four stages: positioning, clamping, measurement, u...

OBJECTIVE To assess the effects of early or late clamping of the umbilical cord in term newborns, assessing the levels of hemoglobin, hematocrit, and ferritin, and their correlation with some of the complications. PATIENTS AND METHODS A prospective study of healthy newborns at term or born by dystotic or eutocic delivery in our hospital between May 2009 until May 2010. Patients were assigned ...

In order to find the ideal distal circulatory support during cross-clamping of the descending thoracic aorta, the author compared the effects of simple shunting (SS) and centrifugal pump (CP) on hemodynamics and metabolisms in mongrel dogs. In group I (control), the aorta was cross-clamped for two hours without SS or CP; in group II (SS), a temporary shunt was placed between the left common car...

The timing of umbilical cord clamping during the third stage of labor has been a point of contention for many years. The estimated combined blood-volume of the fetal and placental unit is 105-110 ml/ kg [1,2]. Two thirds of this volume is in the fetal circulation and one third in the placenta. In his publication “Zoonomia; or The Laws of Organic Life” originally published in 1794, Erasmus Darwi...

BACKGROUND Clamping and cutting of the umbilical cord is the most prevalent of all operations, but the optimal timing of cord clamping is controversial, with different timings offering advantages and disadvantages. This study, for the first time, compares the influence of early and late cord clamping in correlation with oxidative stress and inflammation signaling, Because cord clamping timing m...

BACKGROUND AND PURPOSE A potential source of complication at carotid endarterectomy (CEA) is cerebral ischemia caused by hypoperfusion during clamping of the carotid artery. Configuration of primary collateral pathways may be a major risk factor for development of transient cerebral ischemia during clamping. We investigated whether circle of Willis morphology on 3D time-of-flight (TOF) MR angio...

BACKGROUND AND OBJECTIVES The need for a skilled assistant to perform hilar clamping during robotic partial nephrectomy is a potential limitation of the technique. We describe our experience using robotic bulldog clamps applied by the console surgeon for hilar clamping. METHODS A total of 60 consecutive patients underwent robotic partial nephrectomy, 30 using laparoscopic bulldog clamps appli...
