![]() ![]() Yan ( 3) summarized a reliable posterior approach, in which first the posterior ascending artery branch and then the right upper bronchus are divided, followed by the pulmonary vessels. ( 2), the pulmonary vessels and then the bronchus are divided as in conventional RUL, but in both methods, problems with the hilar structures are encountered. In the single-direction approach of Liu et al. A large proportion (37.2%) ( 1) of pulmonary cancers occur in the right upper lobe and are treated surgically by right upper lobectomy (RUL), which takes into account the complicated anatomical structure of the right upper lobe. Video-assisted thoracic surgery (VATS) has been the standard treatment for early-stage non-small-cell lung cancer (NSCLC). Keywords: Video-assisted thoracic surgery (VATS) right upper lobectomy pulmonary carcinomas posterior ascending branch right upper bronchus By efficiently reducing the operation time and blood loss, our method is potentially superior to conventional right upper lobectomy. Our surgical procedure, posterior single-direction aBVA, consists of dividing the posterior ascending artery branch and then the right upper bronchus, followed by the right upper pulmonary vessels. The preoperative diagnosis was clinical T1bN0M0, stage Ia primary lung cancer. ![]() Based on a suspicion of indolent scar carcinoma, a right upper lobectomy was performed using VATS. During a regular follow-up over 3.5 years, the solid component enlarged and the cystic wall thickened. A 42-year-old male non-smoker was referred to the hospital following the detection of an opacity with a cystic airspace in the right upper lobe during a routine physical examination. Interviews with Outstanding Guest EditorsĪbstract: We describe a case of pulmonary indolent malignancy requiring a strategic surgery and introduce an alternative technique of right upper lobectomy via video-assisted thoracic surgery (VATS) for primary lung cancer patients.Policy of Dealing with Allegations of Research Misconduct.Policy of Screening for Plagiarism Process.The amplitude of the cyclical variations within a broadening wedge increases over time, thus potentially highlighting volatility clusters in higher time-frames. This scenario eventually repeats itself with increased volume, causing impulses and retracements of higher magnitude reinforcing a positive feedback loop until the price is judged overbought even by initial buyers.Ī broadening falling wedge follows the same scenario structure but with sellers instead of buyers. This allows the creation of a new impulse, with only a divergence left. These participants can be composed of initial buyers, accumulating positions, or late traders seeing the potential to buy at a better price. However, before the decline reaches the previously established low, certain market participants buy again. Momentum traders follow the initial impulse further pushing prices up.Ĭontrarian traders judge the price to be trading above its intrinsic value, selling and thus creating a decline in prices. The cause of an ascending broadening wedge is a surge from an initial buying impulse, driving the price higher. Causes Of Broadening Wedgesīulkowski offers a description of the causes of broadening wedges in the market in terms of the market participant's behavior. Selling directly after a partial decline would allow for higher profits.Ĭertain analysts close trades caused by partial rises/declines when the price reaches the support/resistance of the wedge, opening a new position in the case of a breakout while using the metric rule for setting their take profit. Selling directly after a partial rise would allow for higher profits.įor a broadening descending wedge the measure rule would place our take profit at the highest high inside the formation. For a broadening ascending wedge the measure rule would place our take profit at the lowest low inside the formation. ![]()
