Procedure The aortic adventitia is dissected with McIndoe’s scissors away from the proposed site of anastomosis. A side-clamp is applied to the ascending aorta, and its position fine-tuned with a Duvall clamp. A stab incision is made with a 15-blade scalpel and an aortotomy punch passed inside to make a circular hole. Any pieces of…
Procedure After haemostasis of the median sternotomy wound, apply an internal mammary retractor to elevate the left hemi-sternum. The pericardium may be left closed. Position the patient so the internal sternal edge is just above eye-level. This would mean raising the bed and rotating it away from the operator. The operator may be standing. A…
Procedure The patient is positioned sitting at 45 degrees, and hands above head to retract scapula. Scrub up (wash hands, hat, mask, gown, sterile gloves) Identify the triangle of safety: anteriorly the lateral border of pectoralis major, posteriorly the lateral border of latissimus dorsi and inferiorly the superior border of the 5th or 6th rib.…
Procedure The landmark and ultrasound-guided techniques may be used to cannulate usually the right IJV. The patient is supine in a Trendelenburg position (head down) to distend the right IJV. With the head turned to the left, the IJV may be identified superiorly in the carotid triangle anterior to the anterior border of sternocleidomastoid muscle,…
