Dec 04, 2022
Possible intraoperative or postoperative complications and surgical risks should be explained to the patient or relatives. Some unusual risks may not be listed here. Specific surgical procedures may vary according to different patient conditions:
1) Anaphylaxis: intraoperative drugs (contrast agents, anesthetics, etc.) may cause skin allergy, dyspnea, anaphylactic shock, hemolysis, etc.;
2) Puncture site complications: unsuccessful puncture, local hematoma, pseudoaneurysm or arteriovenous fistula formation, and adjacent organ damage.
3) Complications related to selective intubation: vasospasm, intima injury, arterial dissection or vessel rupture; Thrombosis, mural thrombosis or plaque shedding, resulting in blood supply tissue, organ ischemia, necrosis. Cerebrovascular thromboembolism (usually caused by internal carotid artery plaque or embolus loss in the heart).
4) Toxic side effects caused by contrast agents: allergic reactions, gastrointestinal reactions, bone marrow suppression, heart, liver and kidney damage, skin and mucosal ulcers, etc.
5) Infection (both local and systemic).
6) The operation was unsuccessful due to anatomical abnormalities and other reasons, or the need for multiple operations.
7) Intracranial hemorrhage (including arterial or venous hemorrhage) and puncture local hematoma.
8) In the operating room, the course of surgery is aggravated and death;
9) Intraoperative or postoperative aneurysm rupture and hemorrhage resulting in paralysis or death; Intracranial hemorrhage caused by anticoagulant therapy, and compression of blood vessels after bleeding to form cerebral infarction or death;
10) The catheter is broken and knotted.
11) Retroperitoneal hematoma caused by the operation may be life-threatening.
12) Radiation may cause damage.
13) No lesions were found by angiography, and reexamination may be necessary at a later date.
14) Some materials are self-funded.
15) In addition to the above conditions, there are other possible complications of this medical measure or other matters requiring the special attention of patients and their families:
