However, progressive formation of uterine arteriovenous fistula (AVF) after LAM is not described as a significant complication.
A 39-year-old nulligravida
underwent LAM for multiple myomas. On ultrasonography obtained 13 days after LAM, a prominent vascular mass was identified in the post-myomectomy scar. Computed tomographic angiography showed AVF originating from the left uterine BMS202 molecular weight artery. Uterine AVF was endovascularly embolized by metallic coils to avoid future hemorrhage.
Development of uterine AVF after LAM is a potentially life-threatening complication. Early diagnosis and endovascular management can provide a significant benefit for a woman wishing uterine preservation.”
“A series of experiments were performed in vacuum environments to investigate the impact of rf micromechanical system switch contact voltage versus resistance for gold-on-gold contacts at cryogenic temperatures. The purpose
of this work was twofold as follows: (1) to examine whether see more asperity heating models already validated for high temperature contacts were also applicable at cryogenic temperatures and (2)
to explore the implications and validity of prior suggestions that Fedratinib order contact temperatures between 338 and 373 K are high enough to dissociate adsorbed film and/or push them aside but low enough to prevent asperities from becoming soft and adherent. Measurements on two distinct switch types, fabricated at independent laboratories, were performed in the temperature range 79-293 K and for contact voltages ranging from 0.01 to 0.13 V. Contact resistance values at all temperatures were observed to be lower for higher contact voltages, consistent with the aforementioned asperity heating models, whereby increased contact currents are associated with increased heating and softening effects. In situ removal of adsorbed species by oxygen plasma cleaning resulted in switch adhesive failure. Switches that had not been cleaned meanwhile exhibited distinct reductions in resistance at contact temperatures close to 338 K, consistent with suggestions that films begin to desorb, disassociate, and/or be pushed aside at that temperature.
