Robotic-assisted Resection of a Diaphragmatic Metastasis of a Gastrointestinal Stromal Tumor.

Gastrointestinal stromal tumors (GISTs) are relatively rare mesenchymal tumors. The treatment of these tumors has drastically changed based on molecular treatment methods, namely tyrosine kinase inhibitors, which have led to impressive survival benefits. While medical management has enhanced patient outcomes, surgery is still the standard of care for stable, completely resectable primary tumors or metastases that are >2 cm.

Occipital artery to p3 segment of posterior inferior cerebellar artery bypass in treating a complex fusiform aneurysm.

We provide a case report of a 58-year-old man who presented with a ruptured fusiform dissecting aneurysm located at the junction of the vertebral artery and posterior inferior cerebellar artery (PICA). Due to the lesion's complexity, a two-step approach was planned for revascularisation of PICA using the occipital artery (OA) prior to coiling embolisation. An end-to-side OA-PICA bypass was performed with implantation at the caudal loop of the p3 PICA segment.
