    Abstract Purpose: To evaluate the technical success and clinical outcomes of thoracic duct embolization (TDE) using transabdominal antegrade and transcervical retrograde accesses to treat patients with chyle leak.
    Materials and methods: This study was a retrospective, nonblinded, single-institution chart review of all patients aged 18 years or older over a 6-year time frame who underwent lymphangiography with attempted TDE for iatrogenic or spontaneous chyle leaks using transabdominal antegrade and/or transcervical retrograde accesses.
    Results: Ninety-nine patients underwent 113 procedures. Eighty-five patients underwent 1 procedure, and 14 patients required 2 procedures. The technical success rate of TDE was 68% (72/106) with transabdominal antegrade access and 44% (15/34) with transcervical retrograde access. The overall technical success rate of TDE, including both the access methods, was 77% (87/113). The most common reasons for transabdominal access failure were small caliber of the cisterna chyli and thoracic duct (TD) occlusion. Five patients were lost to follow-up. Overall clinical success, defined as resolution of the chyle leak, was achieved in 83% (78/94) of the patients. There were 6 Society of Interventional Radiology (SIR) level 1 adverse events (AEs), 5 SIR level 2 AEs, and 2 SIR level 3 AEs. Nontarget embolization occurred in 2 patients.
    Conclusions: Although transcervical retrograde TDE is a challenging procedure, with a lower technical success rate than transabdominal antegrade access, retrograde access improved the technical and clinical success rates of the treatment of chyle leaks in cases of thoracic duct occlusion, small cisterna chyli, and leaks located in the abdomen.

    Abstract Background: Thoracic duct injury is a rare complication of head and neck surgery. Thoracic duct embolization (TDE) has been proposed to manage postoperative chyle leaks.
    Methods: Twelve patients who underwent lymphangiography for a chyle leak after head and neck surgery (M:F = 5:7, mean 55 years) were retrospectively reviewed. Lymphangiographic findings, technical success, complications, and clinical outcomes were analyzed.
    Results: Chyle leak was identified and TDE attempted in 11 of 12 patients. Three patients required repeat TDE. Technical success of TDE was 86% (12/14). Clinical success for patients with technically successful TDE was 90% (9/10). Median time until drain removal was 2.1 days in nine patients with clinical success. Two major complications were encountered, chylothorax after initial TDE, requiring additional TDE and in one case surgical TD ligation.
    Conclusions: TDE is a safe treatment for chyle leaks after head and neck surgery with high technical and clinical success rates.

    Abstract From 2015 to 2019, 9 patients underwent ultrasound-guided intranodal lymphangiography for the treatment of a chyle leak following thoracic outlet decompression surgery. Chyle leaks were identified by Lipiodol (Guerbet, Roissy, France) extravasation near the left supraclavicular surgical bed in all patients. The technical success rate of thoracic duct embolization was 67% (6 of 9), including fluoroscopic transabdominal antegrade access (n = 4) and ultrasound-guided retrograde access in the left neck (n = 2). Clinical success was achieved in 89% of patients (8 of 9). The mean interval from lymphangiography to drain removal was 6.6 days (range, 4-18 d). No patients had a chyle leak recurrence during clinical follow-up (mean, 304 d).

    Abstract The interdisciplinary model for the management of vascular anomalies relies essentially on effective collaboration and communication between various medical disciplines. In this paper, we discuss the various facets of an organized institutional collaborative model for managing these patients. The case for interdisciplinary collaboration, use of proper terminology, the vascular anomalies center (structure and work flow), referral bases, and collaboration with support group are briefly illuminated. The role of the interventionalists as primary members and leaders in this field is buttressed by the clinical knowledge and competent use of imaging modalities and minimally invasive interventions.
