Creation of a distal re-entry site is widely performed to treat subintimal hematoma. However, this method has a risk of further vessel damage. The present aspiration technique after sealing the entry site by stenting is more promising because the hematoma can be reduced without additional vessel damage. ().

Unlabelled: Persistent sciatic artery (PSA) is a rare congenital anomaly that may involve aneurysmal formations. During endovascular treatment for PSA aneurysm (PSAA) occlusion, guidewire crossing can be challenging due to complex anatomy. We report successful endovascular intervention for PSAA occlusion using the "direct tip injection in occlusive lesions (DIOL)" fashion, in which hydraulic pressure with contrast facilitates guidewire crossing by visualizing the vessel course and expanding the microchannel and vessel lumen.

Background: Endovascular therapy is an effective method for revascularization in lower extremity artery disease, but treating chronic total occlusion (CTO) remains challenging. This is particularly true for patients with severe calcification, poor run-off in below-the-knee arteries, or limited access sites, where even guidewire (GW) passage can be difficult and bidirectional approaches are often not feasible. The tip-detection (TD) method has been reported as a useful technique in coronary artery CTO interventions, allowing real-time visualization of the GW tip direction.

Treatment of chronic total occlusions (CTOs) by percutaneous coronary intervention (PCI) is technically challenging, with exponential difficulty in the presence of specific anatomical features. We present a complex case where procedural success was achieved by sequential PCIs to two separate CTOs in a 'two-in-one' procedure.
