Surgical Pathology Specimens Clinical Aspects

Dissecting aortic aneurysm: a section of aorta is excised which shows a medial haematoma with an associated intimal flap entrance site and often either an intimal re-entrant or adventitial rupture site.

Abdominal aortic aneurysm: surgical repair involves opening the aneurysm and removing the clot. The graft is sewn inside the aorta and the wall of the aorta is closed. The specimen may consist of clot only, or clot with media.

Internal carotid endarterectomy: considered in symptomatic patients who have carotid artery stenosis that narrows the arterial lumen by more than 70%. The specimen may retain the shape of the bifurcation. It consists of luminal plaque with portions of intima and media attached.

Atherectomy: the removal of atherosclerotic plaque by cardiac catherization. Open thrombectomy or embolectomy of peripheral vessels, e.g., femoral artery, is also undertaken for the acutely ischaemic limb.

Vascular grafts: removed because of thrombosis, fibrous obstruction or infection.

Coronary artery bypass graft (CABG): during a second CABG the saphenous vein or internal artery mammary grafts are occasionally removed.

Temporal artery: a biopsy of approximately 2-10 mm length is taken.

Varicose veins: usually inverted during the procedure and not submitted for histology.
