title: Pulmonary tractotomy as an abbreviated thoracotomy technique.
abstract: BACKGROUND
  Operative abbreviated thoracotomy techniques in thoracic trauma include emergency center thoracotomy, ligation of major arterial branches, packing the thoracic cavity for diffuse bleeding, towel clip or Bogota bag closure of the chest, and pulmonary tractotomy. Pulmonary tractotomy with selective vascular ligation was originally described for deep through-and-through lung injuries that did not involve hilar vessels or airways. Pulmonary tractotomy has evolved into use as an abbreviated thoracotomy technique in patients with severe thoracic or multivisceral trauma. As with any operative technique in high-risk patients, specific procedure-related complications may occur and are analyzed herein. The objective of this manuscript is to review the indications, techniques, and results for pulmonary tractotomy in trauma patients requiring abbreviated thoracotomy.
  
  
  METHODS
  Medical records were retrospectively reviewed for 30 of 32 consecutive tractotomy patients treated at Ben Taub General Hospital, during a 3-year period. By using a model for logistic regression analysis, the characteristics of each patient and their clinical course were tested for impact on mortality.
  
  
  RESULTS
  Seventy percent of patients had at least one intraoperative parameter indicative of acidosis (pH < 7.2), coagulopathy (prothrombin time > 13.8 or partial thromboplastin time > 38.0 seconds), or hypothermia (core temperature < 34 degrees C), and 50% of patients manifested two of these three parameters. The mortality rate among the 30 patients was 17%. Three of the five patients who died were noted to be acidotic, coagulopathic, and hypothermic. Twelve of 25 patients who survived more than 1 day had at least one thoracic complication. There were no late deaths. There was one failed tractotomy and one missed injury. A second thoracotomy was not required for control of a lung injury in any patient. Logistic regression analysis showed that intraoperative blood loss was the only predictive factor for mortality.
  
  
  CONCLUSIONS
  Pulmonary tractotomy is a simple and effective technique in injured patients who require an abbreviated thoracotomy and has an acceptable mortality and complication rate. This follow-up report notes that as definitive therapy, tractotomy continues to allow for direct control of bleeding and air leak and obviates the need for formal resection.
