Percutaneous intervention is now the first line therapy, overtaking prior surgical grafting techniques. We report a series of cases with benign acquired chronic vena caval total occlusions treated with endovascular stenting. Methods: This data was collected from a single center, retrospective chart review of the electronic medical record between November 2015 - August 2021. CTOs were identified as those with a duration of symptoms >3 months. Cases with acute thrombosis were excluded. Results: The cohort consisted of seven patients, four were women and ages ranged from 31-66 years. Two patients were on hemodialysis, three patients had pulmonary hypertension and two had chronic thromboembolic pulmonary hypertension (CTEPH). All the etiologies were benign. The procedure utilized hydrophilic wire with support catheters from multiple access sites. All patients were treated with balloon angioplasty and stenting with bare-metal stents. All patients had a technically successful procedure without procedural complications. Conclusions: These cases highlight the complex interventional techniques of CTO revascularization in the SVC and IVC lesions. Large prospective studies examining the technical and clinical success and long-term complications are needed in the future.2 pagesengAttribution-NonCommercial-NoDerivs CC BY-NC-NDhttps://creativecommons.org/licenses/by-nc-nd/4.0/Text
