Regarding percutaneous dilatational tracheostomy (PDT), which of the following is incorrect?
A. Posterial tracheal wall perforation can occur
B. In one study, patients with platelet counts of <50×109/L could still undergo PDT safely with platelet cover
C. Compared with surgical tracheostomy, PDT has lower operative time, similar operative complication rates, less peri-operative bleeding, lower overall post-operative complication rate, lower post-operative incidence of bleeding and lower stomal infection
D. On long-term follow-up of PDT using the Griggs method, compared with other methods, tracheal stenosis is less common and grade of stenosis is independent of the puncture site.
Answer: D
