Despite accurate preoperative assessment and adequate preparation, unexpected, and sometimes disastrous, situations can occur during vascular and endovascular procedures. This latest book in the European Vascular Course series provides vascular and endovascular surgeons with the skills and techniques needed to solve these unforeseen intraoperative complications. It includes thirteen chapters on aortic neck problems during open and endovascular repair, ruptured clamp sites, ureteral lesions, unintentional covering of side branches, totally calcified aorta and embolization. Accidental conditions during carotid and lower limb revascularization are also covered in six chapters and additional challenges are described in another seven chapters.
