Purpose SVC stenting is often used to manage malignant superior vena cava obstruction (SVCO). Stenting is a minimally invasive procedure that offers more rapid symptomatic relief when compared with other management options including chemotherapy, radiotherapy or conservative treatment [1-3].There are different stent designs such as close cell and open cell type, both were used in our center for SVC stenting. Each design has certain advantages and disadvantages as summarized in Table 1.This study aims to evaluate the outcome of SVC stenting...
Read more Methods and materials All cases of SVC stenting performed in our center from July 2019 to June 2024 were retrieved. Indications other than malignant SVCO were excluded. Patient demographics, procedural details and outcomes were reviewed.Technical success was defined as complete coverage of the occlusive lesion with <30% residual stenosis on angiography [1]. Clinical success was defined as subjective relief of SVCO symptoms as documented in clinical notes. Complication was graded according to the CIRSE classification system. Follow up period is defined as the...
Read more Results Total 19 patients underwent 19 SVC stenting procedures during the study period. All cases were caused by malignant SVCO. 16 patients (84%) had lung cancer.Technical success and clinical success were achieved in all cases (100%). Post-stenting balloon angioplasty was performed in 11 cases (58%). Figure 1 illustrated a technical success case of SVC stenting.Intraprocedural complication was detected in 1 case (5%). It was a case of intraprocedural stent migration into the right atrium with close cell stent, managed with additional...
Read more Conclusion SVC stenting is a safe and effective treatment for malignant SVCO. There is no difference in outcome between open cell and close cell stent group.Our study is limited by its retrospective study design, single center study with small sample size and short follow up period.
