Phrenic nerve damage after cardiac surgery. It is therefore preferable to use more modern cardioplegia techniques instead of ice slush. Patients with persistent phrenic nerve injury have increased acute and midterm morbidity after operation as well as reduced quality of life. Phrenic nerve injury is also a risk in coronary artery bypass surgery where the IMA is used as conduit.

However marked paresis remained as evidenced by prolonged latency and a reduced CDAP. What are the symptoms of Phrenic Nerve Damage. This is due to the proximity of the IMA to the phrenic nerve.

Phrenic nerve injury is a well-recognised complication of cardiac surgery that can lead to disabling effects from diaphragmatic dysfunction especially in children and patients with a history of chronic obstructive airway disease. Various mechanisms of injury have been recognised including hypothermia mechanical trauma and possibly ischaemia. The symptoms are varied depending on whether the left or right nerve is damaged.

I was on oxygen for five months before I was able to breath without help because of an elevated diaphragm due to a paralyzed phrenic nerve.

Observed in 5-15 of patients undergoing such surgery. Definitive studies have shown this complication to be related to coldinduced injury during myocardial protection strategies and possibly to mechanical injury during internal mammary artery harvesting. An important factor in hypothermic phrenic nerve injury is the exposure time to the topical.

Bilateral phrenic nerve injury will recover with ventilatory andcardiac and nutritional support death could still occur. Because of its location damage can unintentionally occur during heart or abdominal surgery. It is known risk associated with chest and neck procedures such as coronary bypass surgery CABG neck dissection for head and neck cancer surgery of the lungs heart valve surgery surgery of the aorta thymus gland surgery carotid-subclavian bypass surgery and surgery for thoracic outlet syndrome.

The biggest symptoms of nerve damage after surgery are usually numbness tingling burning or muscle weakness or atrophy. Injury to the phrenic nerve can impair the ability of the nervous system to regulate breathing. Luckily my cardiologist was on top of it and diagnosed it along with pulmonary specialist before leaving the hospital.

Up to 10 of cases of phrenic nerve damage are caused by operative trauma. The use of cooling cardiac jackets during open heart procedures has also resulted in unilateral or bilateral phrenic nerve injury. In this study we also found a prolonged time course of recovery after bypass surgery.
