OBJECTIVE to investigate prospectively the additional value of intra arterial digital subtraction arteriography (IADSA) for decision making in patients with critical limb ischemia (CLI). Treatment plans based on colour-duplex imaging (CDI) were compared with treatment plans based on IADSA. METHODS ninety-eight consecutive patients with 112 legs with CLI(More)
Intracranial mesenchymal chondrosarcoma is a rare, high-grade malignancy with the highest prevalence in young adults. Because of its rarity, most data regarding survival are limited to case studies and small series. We present a 71-year-old woman with an intracranial dural based mesenchymal chondrosarcoma located in the anterior skull base, to our knowledge(More)
