TABLE 1. Operative Characteristics of Patients With Cannulation of the Right Axillary Artery*
Cannulation of the axillary artery is one possible means of establishing cardiopulmonary bypass during surgery of the ascending aorta and aortic arch. Use of a Dacron graft for cannulation has a number of advantages. In this article, we report our experience with this technique in seven consecutive patients in whom we performed an ascending aorta replacement. The associated procedures involved were aortic root reconstruction using David's procedure in two patients, the Bentall procedure in one, the hemi-arch technique in two, the complete arch and elephant trunk technique in one, aortic valve repair in one, and Valsalva sinus reconstruction in one. Circulatory arrest with antegrade cerebral perfusion was carried out in three cases. There was no in-hospital mortality, and there were no vascular or infectious complications related to axillary access. One patient presented with transient paresthesia of the brachial plexus. In all cases, cardiopulmonary bypass flow was adequate.

INTRODUCTION

Peripheral cannulation is used in patients requiring cardiopulmonary bypass before a sternotomy, or when cannulation of the ascending aorta is not advisable, for example in cases of type A aortic dissections, or in patients with aneurysms of the ascending aorta, and aortic arch.

The femoral artery and vein have been the preferred cannulation sites for cardiopulmonary bypass in such cases, although alternative sites such as the axillary arteries, and supraaortic branches have been proposed.1-4 Right axillary artery cannulation permits antegrade perfusion without manipulation of the ascending aorta, and thereby facilitates procedures in the distal ascending aorta and aortic arch. The aim of the present study was to evaluate the efficacy of using a graft during cannulation of the right axillary artery.

METHODS

This was a descriptive study using prospective data from the Hospital Universitario Son Dureta cardiac surgery database. All clinical records were reviewed manually.

In 2004, 8 consecutive patients received cannulation of the right axillary artery using a Dacron graft. In 1 patient, it was decided not to use the technique because of the presence of a retroesophageal subclavian artery. Patient characteristics are shown in Table.

Surgical Approach to the Axillary Artery

Blood pressure in both arms, and core temperature were invasively monitored. The patient was placed in a supine position with arms parallel to each side. Before the median sternotomy, a horizontal skin incision of about 7 cm was made, 2 cm below the median lateral portion of the right clavicle (deltopectoral crest). The pectoral major and minor muscles were dissected, and the vascular and nerve bundle exposed. The axillary artery was identified, dissected, and isolated from the axillary vein and the branches of the brachial plexus (Figure). After heparinization (3 mg/kg), the axillary artery was occluded using vascular clamps. A longitudinal arteriotomy was performed and the 8-mm Dacron graft anastomosed. The clamps were removed and hemostasis verified. The Dacron graft was cut 6 cm from the anastomosis and a 20-F straight arterial cannula was introduced via the graft. Alternatively, the arterial line can be connected to the graft directly with the aid of an adapter. The Dacron tube was fixed to an arterial line and venous cannulation, or median sternotomy was performed as appropriate. On completion of the intervention, and after heparin reversal, the graft was occluded and sectioned using vascular clips before surgical reconstruction.

Cardiopulmonary Bypass

An adequate pump flow rate was achieved, with flows over 4 L/min in all cases (mean body surface: 2 m2). No cases of high pressure in the arterial line were observed. Cooling was performed in all patients until a core temperature of 32oC was reached. In patients with circulatory arrest (n=3), core temperature decreased to 26oC-28oC and antegrade cerebral perfusion (ACP) was performed at 18oC (10 mL/kg, 1-1.5 L/min) via the axillary artery through the clamped brachiocephalic trunk. Mean cardiopulmonary bypass and ischemia times were 150 (19) and 96 (13) mins, respectively. Mean ACP time was 35 (1) min. The mean duration of circulatory arrest with moderate hypothermia was 15 (1) min.

RESULTS

Complications of axillary cannulation

One patient presented with transient paresthesia of the brachial plexus which recovered in 48 h without sequelae. There were no cases of traumatic dissection of the axillary artery. There were no right arm vascular complications and no local complications at the scar site.

Overall Results

There was no in-hospital mortality. No re-operations due to bleeding were required and there were no neurological complications. In 57% of patients, extubation was performed within 24 h. The maximum mean creatine kinase MB isoenzyme (CK-MB) value for the series was 26 (12) mg/dL. Atrial fibrillation was the most frequent cardiovascular complication (50%). One patient presented with a non-Q wave acute myocardial infarction (patient with preoperative type A aortic dissection and occlusion of the right coronary artery).

One patient presented a temporary disturbance in renal function but recovered completely. Renal function in 2 patients with preoperative anuria was satisfactory after the intervention. A transfusion was performed in 85% of patients. The mean length of hospital stay was 10 (6) days (range, 8-22).

Post-Operative Ultrasonography

Transthoracic echocardiography was performed in all patients on discharge. The aortic valve was conserved in 5 of the 6 patients with aortic insufficiency (in 2 interventions using David's procedure, in 1 aortic valve repair, 1 Valsalva sinus reconstruction, and 1 correction of the sinotubular junction). None of the patients had greater than grade 1 positive aortic insufficiency.

COMMENTS

Cannulation of the femoral vessels during surgery for aortic dissection and aneurysms of the aortic arch carries a risk of poor perfusion and retrograde thrombotic embolism and atherosclerotic plaque in patients with extensive atherosclerotic disease of the thoracic, and abdominal aorta.3 In order to reduce these complications, other sites have been proposed for central and peripheral cannulation including the ascending aorta, the supraaortic trunks, and the axillary arteries.1,2,4-6

Cannulation of the right axillary artery during aortic arch procedures facilitates exposure during surgery and provides certain advantages when antegrade cerebral perfusion is used.2

The axillary artery is generally more fragile than the femoral artery and direct cannulation can therefore be traumatic. The most common complications of direct cannulation are dissection of, or damage to the artery. Likewise, closing the arteriotomy after direct cannulation is difficult and can lead to stenosis. Other complications have been described, such as the compartment syndrome in the arm being perfused or the impossibility of achieving adequate flow during cardiopulmonary bypass.7 The risk of these complications can be reduced by using a side graft.3,6,7

In the present series, there were no vascular complications arising from the cannulation of the axillary artery when using the Dacron graft. Closure of the arteriotomy was quick and easy.

In the present series, there were no cases of poor perfusion. In 3 cases, the technique allowed a circulatory arrest with moderate hypothermia to be performed safely, with a surgical field that was free of cannulae. In 1 case, the technique had to be abandoned due to retroesophageal right subclavian artery. This anomaly and the presence of significant atherosclerotic lesions can be detected during preoperative radiological diagnostics and by systematically determining whether asymmetry in pulse and blood pressure between the right and left arms is present.

In other series, complications arising from direct cannulation of the axillary artery have been observed in 4%-8% of patients.3,6,8,9 Schachner et al6 reported a 9% decrease in arterial damage and dissection, and a 4% reduction in cannulation problems when a Dacron graft was used in axillary artery cannulation.6

Based on these results, the axillary artery is our preferred site for cannulation in surgery involving dissection of the aorta and ascending arch. With the aid of a Dacron graft, a lateral anastomosis is performed to facilitate cannulation and establish cardiopulmonary bypass. It also allows for rapid improvisation of circulatory arrest and maintenance of antegrade cerebral perfusion via the brachiocephalic trunk. The technique can also be used when there is significant calcification and atheromatosis in the distal ascending aorta which could complicate cannulation of the artery.

Given the excellent outcomes in this series in terms of mortality and neurological complications, we recommend using this technique in patients requiring surgery of the distal ascending aorta and aortic arch.
