A rare case of abnormally high thoracic duct in neck

Thoracic duct injury can be a cause of significant morbidity if its injury remain undiagnosed during surgery. Knowledge of its course and anomaly should be known to prevent its injury. Presenting a case of 40 year male who was diagnosed to have left buccal mucosa squamous cell carcinoma. During neck dissection, anomalous thoracic duct was found much above the omohyoid muscle. Adequate steps were taken to prevent injury to it. It is necessary to acknowledge thoracic duct and prevent its injury during neck dissection. Knowledge about its anomalous path should be known to prevent its injury. Valsalva manoeuvre should be done at the end of neck dissection to find and thoracic duct injury by observing chyle leak and adequate measures should be taken immediately to prevent morbidity associated with it.

Thoracic duct injury after decortication of lung, new technique to repair thoracic duct in this challenging situation: A case report

Background Chylothorax is a rare form of pleural effusion that can be associated with both traumatic and non-traumatic causes. Very few patients respond to conservative line of therapy. Thoracic duct ligation is often the treatment of choice in post-surgical patients; however, the optimal treatment of this disease process after traumatic injury remains unclear. Case presentation: We present the case of a 46-year-old woman with thoracic duct injury secondary to decortication for post-pneumonic empyema. Conservative therapy and pleurodesis done twice failed. She developed severe cachexia losing 15 kg in 30 days. She was referred to our center for ligation of thoracic duct. Preoperative lymphangiography located the duct injury in upper part of mediastinum. Computerized tomography scan of chest showed collapse of left lower lobe and thickened left pleura, indicating a significant pericardial effusion. She underwent decortication of left lung, pericardial window, and native pericardial patch repair of thoracic duct. Results and Conclusions: In this unusual and complex case, successful resolution of the chyle leak was achieved with new surgical technique of patch repair. The patient recovered well and was now on a normal diet. She has put on 12 kg in four months. We have avoided late complications of thoracic duct ligation by this technique. This nouvelle technique may be recommended as it is simple and effective. Ligation of thoracic duct carries late complications. Isolating right lung by double lumen tube may cause severe hypoxia as left-sided lung is not expanded as in this case.

An Unusual Cause of Chylothorax after Esophagectomy

Chylothorax due to inadvertent thoracic duct injury after esophagectomy is a well-known complication and requires careful postoperative management and timely intervention to prevent potential morbidity and mortality. We present a case of high-output chylothorax after esophagectomy where the source of chyle leak was not in the thorax.

PERCUTANEOUS FLUOROSCOPICALLY-GUIDED TRANSCERVICAL RETROGRADE ACCESS FACILITATES SUCCESSFUL THORACIC DUCT EMBOLIZATION AFTER FAILED ANTEGRADE TRANSABDOMINAL ACCESS

The purpose of this study was to demonstrate the feasibility of percutaneous fluoroscopically-guided transcervical retrograde access into the thoracic duct following unsuccessful transabdominal cisterna chyli cannulation to perform thoracic duct embolization for the treatment of chylothorax. Five patients, including three (60%) women and two (40%) men, with median age of 62 years, underwent percutaneous transcervical thoracic duct access and embolization after failed transabdominal cisterna chyli cannulation for the treatment of chylothorax. In all patients, fluoroscopically-guided percutaneous transcervical retrograde access into the distal thoracic duct was achieved using a 21-gauge needle and an 0.018-inch wire. Following advancement of a microcatheter, retrograde lymphangiography was performed to identify the location of thoracic duct injury. A combination of 2:1 ethiodized oil to cyanoacrylate mixtures, platinum microcoils, or stent-grafts were used to treat the chylous leaks. Technical successes, procedure durations, fluoroscopy times, blood losses, immediate adverse events, clinical successes, and follow-up durations were recorded. Technical success was defined as cannulation of the distal thoracic duct using a transcervical approach followed by treatment of the thoracic duct injury. Adverse events were classified according to the Society of Interventional Radiology guidelines. Clinical success was defined as resolution of the presenting chylothorax. Percutaneous transcervical retrograde thoracic duct access and treatment was technically successful in all patients (n=5). Median procedure duration was 173 minutes (range: 136-347 minutes) with a median fluoroscopy time of 94.7 minutes (range: 47-125 minutes). Median blood loss was 10 mL (range: 5-20 mL). No minor or major adverse occurred. Clinical success was achieved in all patients (n=5). Median follow-up was 372 days (range:67-661 days). Percutaneous fluoroscopically-guided transcervical retrograde thoracic duct access is an effective and safe method to perform thoracic duct embolization following unsuccessful transabdominal cisterna chyli cannulation for the treatment of chylothorax.
