The treatment of Raynaud's phenomenon

Role and rationale for extended periarterial sympathectomy in the management of severe Raynaud syndrome: techniques and results

There is no consensus regarding etiology or best surgical technique for severe Raynaud syndrome in patients with connective tissue disease. Observations after 30 years' experience in more than 100 cases led to the conclusion that an extended periarterial sympathectomy (with or without vein-graft reconstruction) and adjunctive use of Botox topically will offer benefits that exceed palliation and reduce recurrent ulcerations. In this article the rationale for this approach is reviewed, techniques and results are outlined, and a hypothesis for the mechanism of Raynaud attacks is offered.

Long-term results of periarterial sympathectomy

PURPOSE

To compare long-term results (minimum follow-up of 23 months) of periarterial sympathectomy for patients with digital vasospasm secondary to either an autoimmune disease or generalized atherosclerotic disease. Patients with posttraumatic or localized occlusive disease and vasospasm were not evaluated.

METHODS

Twenty-eight patients had periarterial sympathectomy at 1 hospital by 1 senior surgeon. Periarterial sympathectomy was targeted to the areas of ulceration. Twenty patients (with 24 involved extremities and 42 ulcerated digits) had a documented autoimmune disease; 17 patients had scleroderma or an undifferentiated mixed connective tissue disorder, 2 had systemic lupus erythematosus, and 1 had rheumatoid arthritis. Eight patients (with 9 involved extremities and 17 ulcerated digits) had atherosclerotic disease. The primary outcomes were complete healing of all ulcers, a decrease in the number of ulcers, and need for amputation by the end of follow-up. Statistical analysis was done using the Fischer exact t-test.

RESULTS

The average follow-up for all patients was 96 months (90 months for the autoimmune group and 113 months for the atherosclerotic group). Fifteen of the 20 patients (28 of 42 digits) in the autoimmune group had complete healing or decrease in ulcer number. Conversely, only 1 of the 8 patients (2 of 17 digits) in the atherosclerotic group had complete healing or decrease in ulcer number. Eleven of the 42 (26%) digits treated in the autoimmune group required amputation. In contrast, 10 of the 17 (59%) digits treated in the atherosclerotic group ultimately required amputation.

CONCLUSIONS

Periarterial sympathectomy can lead to complete healing and decrease in ulcer number in autoimmune disease patients with digital ischemia from vasospasm. However, our data suggest that periarterial sympathectomy may be of little or no benefit in patients with chronic digital ischemia and vasospasm secondary to severe atherosclerotic disease.

Thromboangiitis obliterans (Buerger's disease): searching for a therapeutic strategy

Treatment of thromboangiitis obliterans (Buerger's disease) includes both surgical and nonsurgical approaches, or a combination of both. A definite therapeutic approach has not yet been set. This article reviews the proposed therapeutic strategies and considers the advantages and disadvantages of each treatment. Cessation of smoking seems to be the only globally accepted therapeutic measure to prevent disease progression. A number of promising novel therapeutic strategies may prove useful for the treatment of this physically and socially mutilating disease.

Peripheral Sympathectomy for Raynaud's Phenomenon: A Salvage Procedure

We retrospectively reviewed the effectiveness of peripheral sympathectomy for severe Raynaud's phenomenon. In this study, a total of 14 digits from six patients with chronic digital ischemic change were included. All patients had pain, ulcer, or gangrenous change in the affected digits and were unresponsive to pharmacologic or other nonsurgical therapies. In all cases, angiography showed multifocal arterial lesions, so microvascular reconstruction was unfeasible. Peripheral sympathectomy was performed as a salvage procedure to prevent digit amputation. The results were analyzed according to reduction of pain, healing of ulcers, and prevention of amputation. In 12 of the 14 digits, the ulcers healed and amputation was avoided. In the other two digits, the ulcers improved and progressive gangrene was limited. As a salvage procedure for Raynaud's phenomenon recalcitrant to conservative treatment, peripheral sympathectomy improves perfusion to ischemic digits and enables amputation to be avoided.

Effects of transvenous regional guanethidine block in the treatment of critical finger ischemia

The objective of this study was to determine the effects of transvenous regional guanethidine block in the treatment of patients with critical finger ischemia. Twenty-seven patients (17 collagen vascular disease, four thromboangiitis obliterans, three embolism, three atherothrombosis) presenting with ischemic rest pain and/or ulcerations of the fingers received a single block with 5 mg guanethidine injected in 60 mL into the clinically more affected hand under 30 minutes of arterial arrest. Marked hyperemia was induced in the treated upper limb, increases (p < 0.01) in finger blood flow, finger skin temperature, and laser Doppler flux were higher and longer lasting than in forearm blood flow, persisting for a whole month. Effects in patients with ischemic finger ulcers were less pronounced than in those without, yet statistically significant increases of all evaluated parameters were observed in these patients too. No effects were seen in the contralateral untreated upper limb or in systemic blood pressure. Subjective symptoms (reduction of rest pain, numbness, vasospastic attacks) were improved in 25/27 (92.6%) patients, ischemic rest pain disappeared in 20/27 (74.1%), and complete healing of finger tip ulcerations within 1 month was achieved in 10/12 (83.3%) affected patients. No side effects were observed. This described method combines good clinical efficacy with lack of undesirable side effects and can be repeated easily. Therefore, this technique is recommended for broader clinical use.

Raynaud's disease: patient education as a primary nursing intervention

The terms Raynaud's disease and Raynaud's phenomenon are often used interchangeably to identify two distinct disease states that initially appear with similar symptoms but then have very different sequelae. Triggered primarily by cold weather, both conditions commonly result in a vasospastic response predominantly observed in the fingers and toes. A review of the relevant health care literature indicates that there is little, if any, information available on Raynaud's disease that would be of particular and specific interest to the nursing profession. So that they can provide appropriate patient teaching, nurses need to be familiar with the precipitating factors, signs and symptoms, evaluation methods, and treatments of Raynaud's disease. This article focuses specifically on Raynaud's disease, which affects many women but relatively few men. A historic perspective on this disease state is provided, and postulated pathophysiologic mechanisms for the onset of this condition are addressed. The patient who is experiencing symptoms of this disease may have complaints of pain and numbness particularly in the fingers. The nurse's primary role is patient education so that the onset of symptoms associated with this disease can be identified and minimized. A discussion of nursing implications with a focus on teaching is provided. A case study is presented of a patient with Raynaud's disease, which will serve to highlight and expound on key information provided throughout the text of this article.
