<b>Purpose</b><br/>This study aimed to evaluate the clinical efficacy and patency of stents placed for symptomatic iliac vein or IVC obstruction caused by malignant tumors. Material and Methods: A total of 34 consecutive patients with malignant iliac vein or IVC obstruction underwent stent placement. We reviewed their electronic medical records, pre- and post-procedural CT scans, and angiograms retrospectively, and evaluated technical success, clinical success, and patient-based and vessel-based reocclusion rates confirmed by follow-up cross-sectional images. The reocclusion rate difference between IVC and iliac stents was also assessed. <br/><b>Results</b><br/>All patients complained of leg and/or trunk edema. The stents were placed in the following locations: IVC (n = 9); iliac veins (n = 19); and both IVC and iliac veins (n = 6). Technical success rate was 100% and the clinical success rate was 87.5% during hospitalization. Cross-sectional area of the affected thigh was significantly decreased after stent placement (mean 11.7%, p = 0.003). The median follow-up period was 65 days (Q1–Q3, 28.5–227.3; IQR, 198.8). The patient-based reocclusion rate was 42.8%. The vessel- based reocclusion rates for IVC (12.5%) tended to be lower than those of iliac veins (45.0%), though the difference was not statistically significant (p = 0.194). <br/><b>Conclusion</b><br/>Stent insertion for iliac vein or IVC obstruction secondary to malignancy is technically feasible and can help to improve patients’ symptoms. IVC stents tend to achieve a higher rate of patency than iliac vein stents.

We report a 54‑year‑old woman with chronic pancreatitis, duodenal obstruction, massive ascites, and refractory thrombocytopenia who developed septic obstructive cholangitis after occlusion of a plastic common bile duct (CBD) stent. Endoscopic exchange failed and PTBD was prohibitively risky. Transjugular intrahepatic biliary stenting (TIBS) provides an alternative route that avoids transperitoneal hepatic capsule puncture. Via right internal jugular access, the right hepatic vein was catheterized, a posterior sectoral bile duct punctured, and a guidewire crossed the distal CBD stricture. A 12 × 80 mm self‑expandable metallic stent was deployed and the transhepatic tract embolized with coils. The patient experienced rapid clinical and biochemical recovery (bilirubin, 13.3 to 1.37 mg/dL) over 9 days postprocedure without any hemorrhagic complications. TIBS is a decisive, life‑saving alternative when standard routes are not possible.

Current percutaneous treatment strategies for acute limb ischemia (ALI) include catheterdirected thrombolysis (CDT) and mechanical thrombectomy. However, about 20% of these patients can have contraindications to thrombolytic therapy. Mechanical thrombectomy is the only option in such patients except for surgical candidates. Manual aspiration thrombectomy using a large-bore aspiration catheter is a preferred first option. However, this technique is sometimes insufficient when the thrombi burden is significant with the risk of distal embolization. In this case report, we would like to introduce a case with acute limb ischemia successfully treated with stentassisted thrombectomy when contraindicated for thrombolysis and failed simple aspiration thrombectomy alone.
