• Embolism: Defined as the obstruction of a blood vessel by a clot (embolus) or foreign substance.
• Ischemia: Deficiency of blood supply to tissues, result of obstruction but not the obstruction itself.
• Hemorrhage: Excessive bleeding, not obstruction.

• Surgical excision of a vein: Term is phlebectomy, not angioplasty.
