Review
Carinal resections are frequently performed for carinal tumors. Resection of the carina due to distal tracheal tumors may be required, and the extension of main bronchial tumors to the carina may lead to carinal resection. This is one of the rarely performed operations in thoracic surgery, which is technically challenging and has a high complication rate. In the early series, perioperative mortality rate was reported as 29% and the five-year survival rate as 15%. Due to its technical difficulties and high complication rates, it is performed only in certain centers. In this review, we discuss techniques related to carinal sleeve resection and prognostic factors in the light of literature data.

Review
There have been significant advancements in medical techniques in the present epoch, with the emergence of some novel operative substitutes. However, the treatment of tracheal defects still faces tremendous challenges and there is, as yet, no consensus on tracheal and carinal reconstruction. In addition, surgical outcomes vary in different individuals, which results in an ambiguous future for tracheal surgery. Although transplantation was once an effective and promising method, it is limited by a shortage of donors and immune rejection. The development of bioengineering has provided an alternative for the treatment of tracheal defects, but this discipline is full of ethical controversy and hindered by limited cognition in this area. Meanwhile, progression of this technique is blocked by a deficiency in ideal materials. The trachea together with the carina is still the last unpaired organ in thoracic surgery and propososal of a favorable scheme to remove this dilemma is urgently required. In this review, four main tracheal reconstruction methods, especially surgical techniques, are evaluated, and a thorough interpretation conducted.

Pleomorphic adenomas are the most common tumors of the salivary glands. Rarely, they occur as benign lesions in the lungs in both the central airways and the lung parenchyma. Herein, we present a case of a 60-year-old smoker who was incidentally found to have an endobronchial mass while undergoing evaluation for a lung nodule. During bronchoscopy, a smooth globular nodule was identified at the main carina and removed using electrocautery snare. Histopathology examination revealed this to be a pleomorphic adenoma.

Review
Coronary angiography is unable to visualise the atherosclerotic involvement of the arterial wall. Bifurcation lesions are particularly difficult to assess by angiography because overlapping mother and daughter vessels often obscure the lesion and carina. On the contrary, IVUS imaging allows for precise, real-time, cross-sectional assessment of all bifurcation lesion segments, enabling measurements of luminal and vessel areas. Moreover, IVUS evaluation of stent expansion, apposition and edge problems is also superior to angiographic assessment. In spite of the lack of adequately powered randomised trials, there is growing evidence from large registries and meta-analyses showing better acute and long-term outcomes of DES implantation guided by IVUS, in comparison to angiography-guided procedures. In this review, we summarise current scientific evidence, the European Society of Cardiology recommendations and the European Bifurcation Club consensus for the use of IVUS in bifurcation stenting.
