Successful treatment of catamenial hemoptysis by single-incision thoracoscopic left S9  + 10 segmentectomy using indocyanine green injection-assisted targeting
AbstractCatamenial hemoptysis is a rare condition. A 28-year-old woman presented with a 1-year history of repetitive hemoptysis occurring on the first day of her menstrual period. Chest computed tomography revealed catamenial hemoptysis during her menstrual period. The patient underwent single-incision thoracoscopic left S9  + 10 segmentectomy using indocyanine green injection-assisted targeting. The endometriosis lesions would not be enhanced by perfusion defects during ICG injection due to the lung contusion. Surgical resection with accurate localization of catamenial hemoptysis was a fundamental treatment ...

Preoperative tracheal resection and reconstruction simulations with patient-specific three-dimensional models
In this study, we describe the use of patient-specific 3D models for tracheal resection. We performed preoperative simulations for two patients diagnosed with tracheal ganglioneuroma and adenoid cystic carcinoma; the mimic operations suggested the necessity of a short cuff intubation tube across the surgical field, indicating the recommended amount of dissection around the trachea and bilateral hilum prior to tracheal reconstruction. The postoperative courses were free from any anastomotic or pulmonary complications. We described the availability of preoperative simulations for complicated tracheal resection and reconstruc...

AbstractDescribed herein the case of a 47-year-old woman who underwent surgical closure of a large fistula between the right coronary artery (RCA) and the superior vena cava with subsequent thrombosis of the ectatic RCA determining myocardial infarction and cardiac arrest. After resuscitation, rheolitic thrombectomy with AngioJet device was performed and anticoagulant treatment was started in addition to antiplatelet therapy. The type of antithrombotic therapy after coronary fistula closure is still debated but long-term anticoagulation should be considered in high-risk cases.

Titanium plate to fix crossed rib can cause cardiac tamponade: A cautionary note
AbstractA 78-year-old woman diagnosed with an infected descending aortic aneurysm underwent graft replacement through a left rib-cross thoracotomy. She developed shock suddenly on the postoperative day 3 owing to cardiac tamponade. We performed emergent surgery and identified a small myocardial laceration in the left ventricular obtuse marginal area and a small perforation on the pericardium. One of the claws used to fix the titanium plate in the cross-rib repair caused this complication. This is a cautionary note regarding this type of titanium plate, which is used in many procedures.
