Pott, pedantry and precision.
The historical section of the Gordon Craig Library at the Royal Australasian College of Surgeons contains a copy of Pott's major work, which includes most of his surgical papers. It also contains three volumes by Sir James Earle, which include most of Pott's papers, together with an account of the life of Pott. What follows is the basis of an illustrated lecture that sought to sample and review these books for those who do not have an opportunity to read them.

The role of physical and chemical characteristics in assessing the performance of a new biological vascular graft.
Information obtained from physical and chemical characterization of vascular grafts can prove valuable in obtaining a preliminary assessment of potential in vivo performance. The data presented illustrate the concept and show that the new biological graft made from bovine ureters has adequate performance characteristics for use as a potentially successful vascular graft.

Aneurysms of the visceral arteries.
Visceral artery aneurysms are uncommon. During the period 1975-88, 32 patients were treated at the Royal Melbourne Hospital for true and false visceral artery aneurysms. There were 18 males and 14 females, with an age range of 12-86 years. Of the 32 patients, 26 were symptomatic and six were asymptomatic. True aneurysms were found in 20 patients and false aneurysms in 10. A further two were dissecting aneurysms. Of the arteries involved, 17 were renal, six were hepatic, five were splenic, one was superior mesenteric, one was left colic and there were two patients with aneurysms at multiple sites. Aetiological factors included atherosclerosis, fibromuscular dysplasia, pancreatitis, and trauma. Only one patient presented in pregnancy. Rupture occurred in 12 patients and two died as a result of this complication. All the true hepatic artery aneurysms presented in this way. Pre-operative investigations included plain radiology, computerized tomography with contrast, nuclear scanning and selective angiography. Operative treatment was required in 22 cases, 12 as an emergency and 10 as an elective procedure. Surgical options included aneurysm excision with or without arterial reconstruction, aneurysmorrhaphy with flap arterioplasty, or ligation of the aneurysm. Embolization was successfully employed in two patients and eight were merely observed without complications. Surgical therapy is recommended for any patient with symptoms, for any woman of child-bearing age and for all hepatic artery aneurysms.

Postpartum rupture of a renal artery aneurysm to a solitary kidney.
We present the case of the first known survivor of postpartum rupture of a renal artery aneurysm where the contralateral kidney was congenitally absent. An important surgical principle, that of establishing the presence of one kidney before removing the other, is illustrated.

Intravenous digital subtraction angiography in patients with carotid territory ischemia: a prospective trial.
To evaluate the place of intravenous digital subtraction angiography (IV-DSA) in the investigation of patients with carotid territory ischemia, we have compared the IV-DSA and conventional angiographic (CA) findings in 40 patients in a prospective study. Arterial disease was assessed by grading stenosis from zero (normal artery) to six (complete occlusion) and recording any luminal ulceration. In 59 of 66 bifurcations imaged by both techniques, the IV-DSA evaluation of any internal carotid artery origin disease was within one grade of the CA assessment, with three false negatives and four false positives. Luminal ulceration was less reliably predicted, and two clinically important middle cerebral artery lesions were missed by IV-DSA. In 11 patients who had carotid endarterectomy, there was a good correlation between surgical, CA, and IV-DSA findings, although some ulcerations were not detected by either angiographic technique. These results suggest that IV-DSA is a sensitive technique for detection of carotid bifurcation stenosis when the study is of good quality, but that intracranial lesions may be missed.

Claudication of the cauda equina.
The term "claudication of the cauda equina" is examined. It has arisen from semantic errors, and a belief in ischaemia for which there is no scientific evidence. Its use tends to hamper rather than assist the investigation of patients with obscure pain in the lower limb. A preferable alternative term, "atypical sciatica", is suggested.
