Technique of angiography and embolization
Several improvements have contributed to the increasingly widespread use of vascular investigations. Low osmolality quickly eliminated contrast media (iopamidol, iohexol) have recently been developed. They can be used in fragile or elderly patients and those presenting cardiac or renal insufficiency. Rapid elimination and better tolerance has resulted in modification in anesthetic procedures. General anesthesia has been abandoned in favor of neuroleptanalgesia. The patient remains conscious during the examination. Timely medication is administered by the anesthesiologist, who is present during the examination. The patient awakens immediately after the procedure. The entire exploration, including pre-anesthetic examination, can be performed during a 24-hour hospitalization. If, however, the patient presents a past history of allergy, premedication is given before the examination.
