INDICATIONS

++

The most common indication is for the administration of chemotherapy or long-term parenteral nutritional support. For these purposes, a port is usually used. For short-term therapies, alternatives include a tunneled central venous catheter or a peripherally inserted central catheter (PICC).

++

PREOPERATIVE PREPARATION

++

The procedure is usually performed as an outpatient. Electrolytes and clotting studies should be checked prior to the procedure. If the patient has had previous central catheters, a careful history should be obtained, as this will help with site selection. Transcutaneous ultrasound can assist with vein localization. A single dose of preoperative antibiotics provides for prophylaxis.

++

ANESTHESIA

++

Moderate sedation and local anesthesia is preferred.

++

POSITION

++

The patient is placed in the supine position. Fluoroscopy should be available. The arms are tucked at each side.

++

OPERATIVE PREPARATION

++

The hair is removed with clippers. The chosen side of the neck/upper thorax is prepped and draped using the maximum sterile barrier technique.

DETAILS OF PROCEDURE

INTERNAL JUGULAR VEIN ACCESS

++

The internal jugular vein may be safer than subclavian venous access. The internal jugular vein is located posterior to the sternocleidomastoid muscle (figure 1). It is usually accessed by a percutaneous route. This chapter demonstrates a right internal jugular cannulation.

++

Preliminary ultrasound of the right side of the neck is done in order to document the patency of the internal jugular vein. With real-time ultrasound guidance and employing a modified Seldinger technique, a small incision is made in the skin of the neck with a 15 blade and the internal jugular vein is cannulated with a small-diameter needle (figure 2a). After removing the syringe, the surgeon places a flexible guidewire (figure 2b). The needle is removed, and over this wire, a 5-French dilator is placed to create a track (figure 3). A 3- to 4-cm transverse incision is made on the upper right thorax two fingerbreadths below the clavicle and a hemostat is passed to create a tunnel between the two incisions (figure 4). Blunt dissection is done to create a subcutaneous pocket on top of the pectoralis muscle fascia for the reservoir (figure 4). The Silastic catheter is advanced through the subcutaneous tissues from the upper thoracic subcutaneous pocket to the neck incision (figure 4). The 5-French dilator is exchanged over a wire for an introducer with a peel-away sheath (figure 5). The dilator and wire are removed from the introducer. The Silastic catheter is advanced through the peel-away sheath (figure 6) and is positioned under fluoroscopy with its tip in the right atrium (figure 7). Keeping the catheter in place with a forceps (figure 6), the sheath is ...
