Prioritisation of vascular outpatient appointments cannot be based on referral letters alone.

BACKGROUND: Vascular referrals include patients with conditions varying from varicose veins of cosmetic nuisance to patients with critical ischaemia, transient ischaemic attacks and abdominal aortic aneurysms. A large number of such referrals are received each week from general practitioners. It is important to prioritise patients with conditions that need to be dealt with quickly. OBJECTIVE: We prospectively reviewed referral letters to two vascular units, one in South Wales and one in the Oxford region to assess whether prioritisation can be made on the basis of referral letters. MATERIAL AND METHODS: All GP referral letters were studied for four months. Only patients with lower limb ischaemic symptoms were included. Degree of urgency requested by the GP was also noted. RESULTS: Of 174 referrals for potential lower limb ischaemia analysed, 145 (83%) proved to be due to peripheral vascular disease. Of these 145 referrals, 72% were referred for claudication. Only 37% and 13% respectively mentioned claudication distance and/or rest pain. Risk factors with reference to diabetes, hypertension, hyperlipidaemia, ischaemic heart disease, atrial fibrillation, cerebrovascular disease and smoking were made in 19%, 43%, 23%, 23%, 10%, 14%, 31% of letters respectively. Clinical signs were poorly documented, with 90% of referrals failing to mention presence or absence of critical ischaemic signs. The GP's own assessment of urgency was not stated in 66% of letters, without which only 3% of patients were seen in the clinic within four weeks, compared with 22% in those in whom urgency was stated. Six per cent of patients when reviewed in outpatients were found to have sufficiently severe symptoms to warrant immediate admission. Regional variation was observed with 57% of Royal Glamorgan Hospital referral letters documenting degree of urgency compared with only 23% of Royal Berkshire Hospital letters (p = < 0.0001). CONCLUSION: Most referral letters were poorly documented with regard to key symptoms, risk factors and clinical signs. The degree of urgency was often not stated. The creation of referral protocols is now being considered.

Management of cardiovascular risk factors by primary care physicians in patients with peripheral arterial disease.

BACKGROUND: Patients with significant coronary artery disease (CAD) are now intensively treated by primary care physicians predominantly because of government pressure and remuneration to prescribe anti-platelet and anti-hyperlipidaemic drugs. Peripheral arterial disease (PAD) with the identical risk factors appeared to us to be less intensively investigated and treated by primary care physicians. OBJECTIVE: To review the treatment of risk factors in all patients referred to two vascular clinics with a diagnosis of suspected PAD. DESIGN: Cross-sectional survey. SETTING: Vascular outpatient clinic in two district general hospitals. PARTICIPANTS: 124 consecutive new patients were studied to determine risk factors and appropriate treatment. RESULTS: Of the 124 patients, 85 (68%) were confirmed to have PAD without evidence of symptomatic CAD. In the PAD alone group, less than 25% received anti-smoking advice (p < 0.0001) and only 36% were prescribed anti-platelet drugs (p = 0.016). Seventy-three per cent of the overall referred patients with hypertension had been treated for this condition and the blood pressure was normal in 71% of the patients with PAD. In patients with hyperlipidaemia, statins had been prescribed in 92% of patients with coexistent symptomatic CAD, but only in 64% of patients with PAD alone (p = 0.009). In the patients with diabetes, only 66% of the PAD alone group had adequate control of their blood sugar (p = 0.185). CONCLUSIONS: It would appear that patients with CAD and PAD are being treated successfully for their risk factors, but patients with PAD alone, sharing the same common risk factors, are being less than optimally treated.

Hybrid repair of type B dissecting aneurysm with associated Kommerell's diverticulum.

Endovascular therapy has revolutionised vascular surgery. Complex open surgical procedures may be replaced with a combination of extra-anatomical reconstruction and endovascular treatment. This minimally invasive approach is associated with a lower peri-operative morbidity and mortality than open repair. We describe a novel 2-stage treatment in a patient with Type B thoracic aortic dissection with subsequent aneurysmal dilatation and the added difficulty of a concomitant aneurysmal aberrant right subclavian artery (Kommerell's diverticulum).

Subclavian Artery Pseudoaneurysm Formation 3 Months after a Game of Rugby Union.

Pseudoaneurysms of the subclavian artery remain a rare complication after fracture of the clavicle. We report a case of delayed diagnosis of a subclavian artery pseudoaneurysm after a closed fracture of the clavicle in a 15-year-old patient, 3 months after the original injury while playing rugby union. Despite several attendances to the Emergency Department with vague symptoms, the final diagnosis was confirmed by duplex ultrasound and Computed Tomography of the thorax. Surgical repair was indicated due to acute limb ischaemia from distal embolisation from a large pseudoaneurysm, with the patient making a full recovery. This case highlights the need for clinical vigilance when assessing patients, particularly on repeated occasions when their recovery appears to be impaired. A thorough history and clinical examination can raise suspicion of even rare occurrences and aid prompt management.

Patient outcome alone does not justify the centralisation of vascular services.

BACKGROUND: The Provision of Vascular Services document from the Vascular Surgical Society of Great Britain and Ireland argues for the centralisation of vascular services into units served by a minimum of four vascular consultants. The rationale for this is the presumed advantages of improved patient care, better utilisation of resources and a more comprehensive arrangement of consultant vascular cover. Since April 1998, the Royal Surrey County Hospital (RSCH) has had a single-handed vascular consultant with out-of-hours cross-district consultant vascular cover. OBJECTIVES: To use P-POSSUM analysis to determine patient outcome from the RSCH vascular unit, and to compare these with previously published P-POSSUM analysis from a major vascular unit in Leeds. PATIENTS AND METHODS: All patients undergoing major vascular surgery or amputation between April and November 1998 were analysed. RESULTS: 86 patients underwent 102 surgical procedures in 92 separate admissions. Data retrieval was 100%. Predicted (E) mortality 16 cases; observed (O) mortality 13 cases; O:E ratio 0.80. Predicted morbidity 26 cases; observed morbidity 19; O:E ratio 0.73. O:E ratio for mortality from Leeds = 0.83. CONCLUSIONS: Patient outcome in a single-handed vascular unit, with cross-district consultant cover, is equivalent to that found in a major vascular unit. Centralisation of vascular services cannot be justified on the basis of differences in patient outcome.

Gastro-colonic anastomosis--a viable option in extensive small bowel infarction.

INTRODUCTION: We have previously presented a patient with massive small and large bowel infarction and demonstrated that even with only a few inches of remaining small bowel an almost normal life-style and diet is possible. PATIENT: Recently, we have looked after a young and otherwise fit female patient who suffered mesenteric venous gangrene of the whole small bowel from the Ligament of Treitz to the caecum. In order to achieve gastro-intestinal continuity and to avoid the torrential fluid loss associated with high fistula, an anastomosis between the stomach and the transverse colon was formed. RESULTS: We are surprised to find that despite the extensive resection our patient maintains a good quality of life and is able to look after her young family.

Multiple aneurysms associated with congenital rubella.

We describe the case of a woman with congenital rubella who presented with backache. Plain abdominal X-ray revealed calcification of a superior mesenteric artery aneurysm. Intra-arterial digital subtraction angiography demonstrated multiple aneurysms of the arteries to the upper and lower limbs and the viscera. We have not found another report in the literature of the association of congenital rubella with multiple aneurysms.
