title: [Resection and reconstruction of the carina with separate two-lung high-frequency jet ventilation].
abstract: Carinal resection and reconstruction via a right transpleural approach in an hypoxemic patient provides difficult maintenance of satisfactory gas exchange when one lung ventilation is inadequate. The present case report concerns a 62-year-old patient with chronic obstructive airways disease and a carinal squamous cell carcinoma. He underwent tracheobronchial reconstruction surgery by Barclay's procedure through a right postero-lateral thoracotomy. During resection and reconstruction phases, the gas exchange was maintained by a new technic: high-frequency-jet-ventilation (HFJV) with two small-bore catheters through the endotracheal tube and JVHF ventilators adjusted to the compliance of each lung (high for the right lung, low for the left one). No circulatory changes were observed during the sutures lines phase (90'). The oximeter and the arterial blood gas values show an adequate procedure. The immediate post operative period was unremarkable and uncomplicated. The histological diagnosis was squamous cell carcinoma involving the carina with one metastatic pretracheal lymph node and microscopic infiltration of the left main bronchus resection margin. Sixteen grays postoperative radiotherapy was required. Ten months after the patient is alive, without tumor recurrence. HFJV greatly facilitates surgery by avoiding endobronchial intubation with large cuffed tubes into the surgical field. In patients with low pulmonary reserve, bilateral lung HFJV is required: two JVHF ventilators with different ranges delivering separate ventilation to the right and left lungs avoid left hypoventilation and right surgical emphysema and insure good surgical conditions.
