Medium- and Long-Term Outcomes of Autologous Fat Grafting to Hands and Feet for Patients With Raynaud Phenomenon

BACKGROUND

Autologous fat grafting (AFG) has emerged as a promising treatment option for Raynaud phenomenon. However, existing studies are limited by short follow-up, and there is little evidence regarding predictive factors for successful outcomes.

METHODS

A retrospective chart review and standardized phone interviews were performed for all patients (n = 17, 65% response rate) treated with AFG to the hands or feet at our institution for primary or secondary Raynaud from 2010 to 2021. Each occurrence of AFG was defined as a separate surgery (n = 23), with an average follow-up of 3.7 years.

RESULTS

At follow-up, patients reported a 31% reduction in cold attack frequency, a 45% reduction in the intensity of individual attacks, a 29% reduction in the duration of attacks, and a 40% improvement in overall Raynaud Condition Score (P < 0.01). Although initial AFG to an extremity significantly improved symptoms, subsequent attempts were not shown to statistically improve outcomes. Digital ulcers were present in 65% of cases, and AFG resulted in ulcer healing in 87% of those cases. Median duration of maximum symptom relief was 1 year postoperatively, with 74% of patients reporting diminishing symptom relief by 4 years postoperatively. Those with a BMI ≥25, with primary Raynaud phenomenon or without preoperative ulcers experienced significantly longer symptom relief (P < 0.05). Average patient satisfaction was 7.7 of 10, and 91% would recommend the procedure to others.

CONCLUSIONS

Autologous fat grafting is an effective, albeit sometimes temporary, treatment for Raynaud and digital ulcers. Certain patients may be more likely to experience lasting symptom relief beyond 1 year.

Efficacy analysis of minimally invasive surgery for Raynaud's syndrome

BACKGROUND

Raynaud's syndrome (RS), also referred to as Raynaud's phenomenon, is a vasospastic disorder causing episodic color changes in extremities upon exposure to cold or stress. These manifestations, either primary Raynaud's phenomenon (PRP) or associated with connective tissue diseases like systemic sclerosis (SSc) as secondary Raynaud's phenomenon (SRP), affect the quality of life. Current treatments range from calcium channel blockers to innovative surgical interventions, with evolving efficacy and safety profiles.

METHODS

In this retrospective study, patients diagnosed with RS were selected based on complete medical records, ensuring homogeneity between groups. Surgeries involved microscopic excision of sympathetic nerve fibers and stripping of the digital artery's adventitia. Postoperative care included antibiotics, analgesia, oral nifedipine, and heat therapies. Evaluation metrics such as the VAS pain score and RCS score were collected bi-weekly. Data analysis was conducted using SPSS 26.0, with significance set at p < 0.05.

RESULTS

In total, 15 patients formed the experimental group, with five presenting fingertip soft tissue necrosis and ten showing RS symptoms. Comparative analysis of demographic data between experimental and control groups, both containing 15 participants, demonstrated no significant age and gender difference. However, the "Mean Duration of RP attack" in the experimental group was notably shorter (9.47 min ± 0.31) than the control group (19.33 min ± 1.79). The RS Severity Score also indicated milder severity for the experimental cohort (score: 8.55) compared to the control (score: 11.23). Postoperative assessments at 2, 4, and 6 weeks revealed improved VAS pain scores, RCS scores, and other measures for the experimental group, showing significant differences (p < 0.05). One distinctive case showcased a variation in the common digital nerve and artery course in an RS patient.

CONCLUSION

Our retrospective analysis on RS patients indicates that microsurgical techniques are safe and effective in the short term. As surgical practices lean towards minimally invasive methods, our data supports this shift. However, extensive, prospective studies are essential for conclusive insights.

Scleroderma and Raynaud Phenomenon: The Cold Truth Regarding the Use of Operative Management

BACKGROUND

Raynaud phenomenon, with and without scleroderma, is a common vasospastic condition that manifests with extremity pain and skin discoloration. When conservative management fails, complications such as ischemia, ulceration, and gangrene may warrant surgical intervention. The purpose of this study was to determine the risk factors and use of surgical intervention in this population.

METHODS

A national insurance claims-based database with patient records from the Centers for Medicare and Medicaid Services was used for data collection. Patients with first diagnoses of Raynaud phenomenon, scleroderma, or both between 2005 and 2014 were identified. Primary outcomes included the presence of upper extremity amputation or vascular procedure, and history of amputation within 5 years of a vascular procedure. Secondary outcomes included hospital admissions, upper extremity wounds, and amputation within 1 year of diagnosis.

RESULTS

The Raynaud phenomenon, scleroderma, and Raynaud phenomenon with scleroderma cohorts consisted of 161,300, 117,564, and 25,096 patients, respectively. A diagnosis of both Raynaud phenomenon and scleroderma increased the odds of upper extremity amputation by 5.4-fold, vascular procedure by 4.8-fold, and amputation within 5 years of a vascular procedure by 1.5-fold. Patients with Raynaud phenomenon or scleroderma alone were 3.1 and 5.6 times less likely to undergo amputation within 5 years of a vascular procedure, respectively.

CONCLUSIONS

Patients with both Raynaud phenomenon and scleroderma have higher likelihoods of having upper extremity amputations, vascular procedures, and amputations following vascular procedures compared to each diagnosis alone. Vascular procedures are rarely being performed. Further research is necessary to establish a standard of care and determine whether early and more frequent intervention with vascular procedures can decrease amputation rates in this patient population.

Peripheral Nerve Blockade for Patients With Raynaud Phenomenon and Other Causes of Digital Ischemia: A Case Report and Practice Implications

Raynaud phenomenon can be an idiopathic benign disease, or it can be associated with vascular insufficiency due to arterial disease caused by other processes. Medical management of Raynaud phenomenon can be difficult, and digital ischemia, gangrene, and ulcers may occur secondary to vascular insufficiency. This case report describes the anesthetic management of a patient with a diagnosis of Raynaud phenomenon who presented to the perioperative area for débridement and distal amputation of the right third finger, which had become necrotic and gangrenous. An ultrasound-guided supraclavicular nerve block was performed preoperatively with 15 mL of 1.5% mepivacaine and 15 mL of 0.5% bupivacaine. The block was performed without complication, and the patient tolerated the procedure. A review of literature related to the use of peripheral nerve blockade for the treatment of digital ischemia is discussed. Ultrasound-guided technique is considered the gold standard for the performance of peripheral nerve blocks because this technique provides better efficacy and safety. These same ultrasonographic skills can expand anesthesia providers' practice beyond nerve blockade for anesthesia and analgesia with the addition of treatment and management of digital ischemia.

Extended Periarterial Sympathectomy: Evaluation of Long-term Outcomes

BACKGROUND

Periarterial sympathectomy is a proposed surgical treatment for patients with refractory Raynaud syndrome; however, there is debate regarding the indications and extent of dissection. Due to the segmental arterial sympathetic innervation, we favor an extended sympathectomy in concert with vein graft reconstruction of occluded vessels when necessary. The purpose of this study is to examine outcomes of extended periarterial sympathectomy in our patients.

METHODS

A retrospective chart review was performed on 46 patients who underwent 58 periarterial sympathectomies (12 bilateral) since 1981. The data collected include demographics, comorbidities, previous therapy, operative details, and surgical outcomes. In addition, we contacted available patients for a phone survey.

RESULTS

Of 58 cases, 68.9% were female, 29.3% were current smokers, and 58.6% had known connective tissue disease. Thirty-three vein graft reconstructions were performed with a long-term patency of 77.4%. Sustained improvement of ischemic pain was reported in 94.8% of cases, and 78% of patients with ulcers completely healed. For the most symptomatic fingertip, mean Semmes-Weinstein monofilament measurements improved from 4.15 preoperatively to 3.29 postoperatively ( P ≤ .05). Mean follow-up was 3.97 years. Of 10 patients contacted by telephone, all reported a decrease in frequency and severity of Raynaud attacks, while 9 reported a long-term decrease in pain an average of 11.6 years after surgery.

CONCLUSIONS

Extended periarterial sympathectomy is an effective and safe procedure for patients with refractory Raynaud syndrome. Our data demonstrate long-term improvement in ischemic pain and sensibility, along with a high rate of ulcer healing and patient satisfaction.

[Severe Raynaud's syndrome treated by lumbar sympathectomy]

Avoiding exposure of extremities to cold combined with pharmacologic treatment usually suffice in the attempt to suppress the related symptoms of Raynaud's syndrome. This case report describes a severe case of Raynaud's syndrome affecting the lower extremities of a 16-year-old female. She was referred to a centre of vascular surgery with severe vasospasms of the feet. After failed attempts of pharmacologic treatment, a laparoscopic lumbar sympathectomy was performed with no complications and a slight reduction of symptoms three years post-surgically.

[Lumbar sympathectomy literature review over the past 15 years]

INTRODUCTION

Lumbar sympathectomy (LS) irreversibly damages a part of the sympathetic trunk and adjacent ganglia between L1 and L5, typically between L2 and L4. The first LS was performed in 1923. Initially, it used to be performed very often; however, with the progress of vascular and endovascular surgery its importance gradually continues to decline. The aim of the paper is to present literature review focusing on LS over the past 15 years.

METHOD

Literature review of 113 academic articles found in academic journal databases.

PATHOPHYSIOLOGY

Irreversible interruption of the efferent innervation leads to relative vasodilation of small vessels in lower extremities (α1-receptors blockade), and it reduces the volume of sweat due to inactivation of eccrine glands and nociception from lower limbs.

INDICATION

Raynaud´s phenomenon, thromboangitis obliterans, non-revascularizable peripheral arterial disease (PAD) (Fontain grade III-IV), hyperhidrosis, persistent pain in lower extremities, chronic pain of amputation stump, frostbites, chilblains.Effect: The three largest studies showed a positive effect in 63.6-93.4% cases of PAD and in 97%100% cases of hyperhidrosis. The positive effect was defined as warmer lower extremities, increased blood flow, acceleration of chronic defects healing, sweating disappearance and pain reduction.

CONCLUSION

Lumbar sympathectomy still remains a useful method in the treatment of above mentioned diseases if properly indicated.

KEY WORDS

Raynaud's phenomenon (secondary)

INTRODUCTION

Raynaud's phenomenon is episodic vasospasm of the peripheral vessels. It presents as episodic colour changes of the digits (sometimes accompanied by pain and paraesthesia), usually in response to cold exposure or stress. The classic triphasic colour change is white (ischaemia), then blue (de-oxygenation), then red (reperfusion). Raynaud's phenomenon can be primary (idiopathic) or secondary to several different conditions and causes. When secondary (e.g., to systemic sclerosis), it can progress to ulceration of the fingers and toes. This review deals with secondary Raynaud's phenomenon.

METHODS AND OUTCOMES

We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of surgical interventions in complicated secondary Raynaud's phenomenon? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found two studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review, we present information relating to the effectiveness and safety of the following interventions: botulinum toxin, simple debridement/surgical toilet of ulcers, peripheral sympathectomy (digital, digital plus sympathectomy of the ulnar and/or radial artery, ligation of the ulnar artery), cervical/thoracic sympathectomy, arterial reconstruction (venous graft, arterial graft, balloon angioplasty), and amputation.

[The experience with thoracoscopic sympathectomy for the treatment of distal lesions of limb arteries]

The study included 107 patients with distal lesions of limb arteries treated with the use of thoracoscopic sympathectomy. The best results in the early postoperative period were obtained in patients with Raynaud's disease. Modifications introduced into the methods of its treatment permitted to retain effectiveness of sympathectomy till the late postoperative period in 90% of the patients. Surgery for obliterative endarteritis and atherosclerosis was viewed as a possibility to preserve the supporting function of the limb. This purpose was attained in 73.2 and 62.5% of the patients respectively in the early and in 62 and 25% in the late postoperative periods.

[Comparative estimation of the results of open and endoscopic thoracic sympathectomy in the treatment of Raynaud's phenomenon]

Comparative analysis of thoracic sympathectomy efficacy, performed for Raynaud's phenomenon (RP), was accomplished, concerning application either endoscopic or open method. In 62 patients, suffering RP, open or endoscopic thoracic sympathectomy was done in surgical and vascular departments in 1997-2007 yrs. In 32 (51.61%) patients there was performed endoscopic thoracic sympathectomy, in 30 (48.39%)--upper thoracic sympathectomy, using extrapleural supraclavicular access, according to V. N. Klimenko. Immediate results of upper thoracic sympathectomy did not differ trustworthy depending on any method or access. Late follow-up results of upper thoracic sympathectomy were worse than immediate results by 28%--in endoscopic variant and by 43% --in the open one. The positive results rate after endoscopic thoracic sympathectomy have exceeded that after conducting the open one by 15.18%.

[Experience with thoracoscopic sympathectomy in distal lesions of lower-limb arteries]

We studied the results outcomes of thoracoscopic sympathectomy in 107patients with distal lesions of lower-limb arteries. The best results in the early postoperative period were observed in patients with Raynaud's disease and syndrome, reaching 100% efficacy. Due to implementation of novelties, we managed to preserve the efficiency of sympathectomy in 90% of patients with this pathology in the remote period. In patients with obliterating endarteritis and atherosclerosis, the efficacy of the operation was regarded as a possibility to preserve the supporting function of the extremity. In the postoperative period this goal was achieved in 73.2% and 62.5% of patients, respectively, while in the remote period in 62% and 25%, respectively.

[Nonreconstructive revascularizing operations in limb ischaemia]

Presented herein are the findings of experimental studies substantiating interrelationship between osteogenesis and blood circulation, as well as effects of surgical interventions based on excitation of reparative regeneration of the bone and aimed at improvement of blood circulation in the extremities. Reflected also are the main indications for the use of each operative intervention concerned. Based on the clinical findings obtained by follow up of 1,477 patients operated on for limb ischaemia secondary to obliterating arterial lesions efficacy of the methods of treatment devised is demonstrated.

Efficacy of cervicothoracic sympathectomy versus conservative management in patients suffering from incapacitating Raynaud's syndrome after frost bite

BACKGROUND

Raynaud's syndrome is a known complication of cold injuries. Stress, smoking and metabolic diseases may further aggravate the disease course. The purpose of this study was to determine the efficacy of Cervico-thoracic sympathectomy as compared to conservative management in severe Raynaud's syndrome after frostbite.

METHODS

This non-randomized controlled trial was conducted at Railway Hospital, Rawalpindi and Islamic International Medical Complex, Islamabad between January 1999 and June 2006. All patients sustained severe cold trauma in the mountain ridges of Himalayas in Kashmir. In all cases, an informed consent was obtained from patients and families. All operations performed were free of charges. Out of the total 48 patients who developed incapacitating Raynaud's syndrome of the upper limbs after frost bite, 17 patients underwent thoracic sympathectomy through anterior supraclavicular route. Remaining 31 patients were treated conservatively and were placed in the control group. Data was collected on pre-designed proforma and assessed using SPSS (version 11). Chi-square test was applied to assess the effectiveness of the two treatment modalities.

RESULTS

All operated cases initially showed improvement in symptoms and incapacitation. Among sympathectomised patients, 11 patients became symptom free and 3 patients showed mild but improved symptoms. Two patients after initial transient improvement developed incapacitating symptoms requiring further treatment, one patient developed gangrene ofdistal phalanx nine month after sympathectomy requiring amputation of the finger. Frequency of attacks and duration between the attacks reduced in all operated patients of cervical sympathectomy (p < 0.05) as compared to conservative management.

CONCLUSION

Cervical sympathectomy is a very effective modality of treatment in patients having severe Raynaud's disease of upper limbs secondary to frost bite.

[Thoracoscopic sympathectomy for arterial ischemia of the upper extremities: a case report]

INTRODUCTION

Thoracoscopic surgery reduce the morbidity of sympathectomy. Major indications of video-assisted sympathectomy (VAT) include hyperhidrosis, Raynaud's disease, causalgia, and reflex sympathetic dystrophy. Because little information is available in the national and international literature VAT sympathectomy in the treatment of upper extremities ischemia, we decided to present our first case.

CLINIC CASE

The 38 years old patient was hospitalized for left upper-extremity ischemia (Raynaud's syndrome). Thoracoscopic sympathectomy was performed with resection of the main trunk proximally immediately after the stellate ganglion and distally at the level of T4 and identification and resection of 2 collateral branches of the sympathetic chain T2-T3.

RESULTS

The postoperative evolution demonstrated evident clinical benefit. The thermography performed postoperative showed hyperthermia and hyper-vascularization in the left hemithorax with a difference of temperature of 2 degrees C between the two sides of the thorax.

COMMENT

Before the advent of VAT, thoracic sympathectomy was performed only in highly selected patients because of its invasiveness. Now VAT sympathectomy is considered in most cases as the last resort to prevent extensive and successive amputation. Because the procedure is minimally invasive, safe, and associated with a low rate of complications, it should be considered earlier in the natural course of this disease.

Long-term effects of thoracic sympathectomy on microcirculation in the hands of patients with primary Raynaud disease

OBJECTIVE

Videothoracoscopic sympathecomy is a widely used treatment modality in patients with severe Raynaud disease, but the reported late results are less than favorable. There have been no direct studies of the long-term effect of sympathectomy on microcirculation in the hands of these patients.

METHODS

In 25 patients with Raynaud disease treated with videothoracoscopic Th2-Th4 sympathectomy, we performed basal laser-Doppler flowmetry and measured the maximal refilling time after 1-minute occlusion measurements preoperatively and at 1 week, 6 months, and 1, 2, 3, and 5 years after the sympathectomy. The results were compared with the same measurements obtained in the group of 50 healthy individuals.

RESULTS

The patients' symptom severity was assessed by using the visual analogue scale. The basal capillary flow and the maximal refilling time improved after the sympathectomy to a level not different from that seen in the healthy population, and the effect was maintained during the 5-year follow-up period. The patients' symptom severity scores diminished to zero in the early postoperative period and increased to 28% of their initial value 5 years after the operation.

CONCLUSIONS

The videothoracoscopic Th2-Th4 sympathectomy produces excellent and long-lasting improvement of microcirculation function in patients with Raynaud disease. The mild return of symptoms might be due to factors other than the capillary blood flow alterations.

[Manifestations of scleroderma at the hand--options for hand surgery in an interdisciplinary concept]

Clinical manifestations of scleroderma at the hand include Raynaud's phenomenon, calcinosis cutis, sclerodactylia and teleangiectasia. With the progression of the disease, cutaneous and joint contractions, acro-osteolysis, necrosis of the finger tips, and even extensive digital ulceration are likely to occur. These painful and often rapidly advancing lesions cause loss of function and disfigurement and, untreated, often lead to mutilation of the affected hand. Only an interdisciplinary management including the hand surgeon, the rheumatologist, and the physiotherapist can guarantee optimal treatment. Drug therapy should be included as well as physical therapy. Both should be made use of before and accompanying surgical treatment. Surgical therapy consists of treatment of the infections, excision of calcinosis, arthrodesis, in particular of the proximal interphalangeal joints, and sympathectomy. Amputation remains a final option, whereas with timely and sufficient treatment, amputations can be avoided and an improvement of function and an alleviation of the symptoms can be achieved. Among the non-operative treatment options, behavioural training, calcium antagonists, prostacyclin derivatives, topical nitrates as well as plexus anesthesia and stellatum blocks have proved to be effective. Recent drug therapies include endothelin-receptor antagonists for the prevention of digital ulceration and phosphodiesterase-V antagonists in treatment of Raynaud's phenomenon and induction of ulcer healing. With reference to several cases seen at our institution, we propose an interdisciplinary treatment concept for acral manifestations of scleroderma.

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.

Bilateral pain relief after unilateral thoracic percutaneous sympathectomy

PURPOSE

To present a case of unexpected bilateral pain relief following unilateral thoracic percutaneous sympathectomy.

CLINICAL FINDINGS

We present a case report where severe ischemic pain due to paraneoplastic Raynaud's syndrome with distal gangrene was successfully treated by means of percutaneous thoracic sympathectomy. A unilateral T2, T3 radiofrequency sympathectomy combined with small volume phenol injection resulted in unexpected bilateral pain relief.

CONCLUSION

Our observations from this case report suggest a possible crossover of sympathetic innervation at the cervical and thoracic levels. Percutanenous thoracic radiofrequency sympathectomy is a feasible option for the treatment of refractory ischemic upper limb pain.

Thoracoscopic sympathectomy for Raynaud's phenomenon--a long term follow-up study

OBJECTIVES

To assess the long term results of thoracoscopic sympathectomy for Raynaud's phenomenon.

DESIGN, MATERIALS AND METHODS

A retrospective study of 34 consecutive patients who were treated for Raynaud's phenomenon by thoracoscopic sympathectomy from 1996 to 2005. Eight patients presented with ulcerations of the digits and 10 had severe ischaemia without ulcerations. The hospital records were retrieved and questionnaires were mailed to the patients for follow-up.

RESULTS

The questionnaire was answered by 91% of patients after a median follow-up time of 40 months. An immediate effect was seen in 83% of the patients but symptoms recurred in 60% during the follow-up period. Compensatory sweating occurred in 63 and 30% reported gustatory sweating. Thirteen patients (43%) regretted having the operation.

CONCLUSION

The majority of patients with Raynaud's phenomenon have an excellent immediate effect from thoracoscopic sympathectomy and one third achieve a long lasting effect. Side effects are frequent. We now only use thoracoscopic sympathectomy in severe cases of Raynaud's phenomenon.

Microsurgical distal sympathectomy in chronic vasospastic syndromes of the hand

The authors propose a microsurgical technique to treat upper limb chronic digital ischemia that is resistant to medical therapy. The adventitiectomy technique on digital arteries is used here to remove the fibrous tissue and the vasoconstrictor sympathetic nervous fibers contained in it. This operation is a valid alternative to traditional proximal sympathectomy.

Revascularization in distal lesions of upper extremity arteries

A study was made of the course of ischemia and hemodynamic disorders in 53 patients with occlusion of the distal arterial system of the upper extremities. Circulation was examined by ultrasound Doppler, tetrapolar rheology, transcutaneous oxymetry and angiography. Critical ischemia was discovered in 58.5% of patients. In occlusion of one of the forearm arteries, extremity circulation was made for. Circulatory decompensation was recorded in occlusion of both forearm arteries with intact distal bed and non-functioning palmar arches of the hand as well as in lesions of hand and finger arteries. All 53 patients were operated on, 66 operations were accomplished using magnifying optic appliances. Provided the distal bed was well preserved, use was made of direct revascularization techniques (36) whereas non-standard methods were employed in the event of its obliteration: arterialization of the outlets of the subcutaneous veins of the hand and autotransplantation of the greater omentum (30). Beneficial results were obtained in 91.5% and unsatisfactory in 8.5% of patients. The lethality accounted for 1.2% while the incidence of amputations was quoted as 5.7%. Good results offer the period as long as 5 years were well preserved in 87.6% of patients. Our experience indicates the efficacy of the use of revascularization techniques for the treatment of different versions of occlusion of the distal segments of upper extremity arteries.

Indications for endoscopic thoracic sympathectomy

The thoracoscopic approach to the sympathetic chain has diminished the trauma of previous open sympathectomy. The minimal trauma has opened the way to manipulate the chain for several conditions. Hand sweat is the most common indication resulting in patient satisfaction 2-13 years after surgery in more than 90%. High satisfaction was also obtained in patients with angina pectoris and a very disabling condition, facial blushing (85 %). Somewhat poorer results were obtained in patients with facial and axillary sweating. In patients with Mb Raynaud-all had recurrences within a year. Since severe side effects, especially compensatory sweating, may occur, the ETS procedure should be reserved only for patients with severe problems where other treatments have failed.

[Thoracic sympathectomy performed by videothoracoscopic technique]

Thoracic sympathectomy is a method for a segmental elimination of functions of the sympathetic system by the excision of its Th2-Th3 ganglia. The procedure can be performed both using open and videoscopic technique.

OBJECTIVE

The purpose of the study was the evaluation of efficacy of videoscopic thoracic sympathectomy.

MATERIAL AND METHOD

From 1993 to 2003 we performed 53 videoscopic thoracic sympathectomies in patients with Raynaud's syndrome and upper limb hyperhidrosis.

RESULTS

In all patients that underwent thoracic sympathectomy we obtained a positive reaction to a segmental excision of the sympathetic trunk. Patients with Raynaud's showed a significant improvement in symptoms in 76% of cases after a 4-year observation while patients with hyperhidrosis in 100%. The time of hospitalisation was 3.5 days in average. Postoperative complications were observed in two patients (3.7%). Videoscopic thoracic sympathectomy provides good therapeutic and cosmetic results and deserves more common use compared with open technique.

[Surgical anatomy of the thoracic sympathetic trunk]

Peculiarities of anatomical structure of cervical and thoracic parts of sympathetic trunk were studied. There was trusted, that in the upper extremities innervation a "lateral branch" of II thoracic sympathetic ganglion owes important significance. The method of TV surgical thoracic sympathectomy, permitting to improve late follow-up results of treatment in patients with Raynaud disease was elaborated.

[Assessment of thoracic sympathectomy by transpleural posterolateral and thoracoscopic approach in surgical treatment of Raynaud's syndrome]

Operative treatment of patients with Raynaud's Syndrome is rarely used, and is recommended by most authors only in the case of disthrophic changes or so advanced symptoms, which disturb normal social and daily life. Recently, thoracoscopic sympathectomy is applied more frequently. The aim of this study was to assess the usefulness of thoracoscopic sympathectomy by the presentation of early and long-term outcome of 43 thoracic and eight lumbar sympathectomies performed in 41 patients with Raynaud's Syndrome. Transpleural posterio-lateral thoracotomy was performed 29 times in 27 patients, whereas thoracoscopic sympatectomy 14 times in 8 patients. Surgical techniques, early and long-term results were discussed. Based on early and long-term outcome, there were no significant differences between applied surgical techniques. Moreover, thoracoscopic sympathectomy was safe in the aspect of a short duration as well as good therapeutic and cosmetic effect of the procedure. It should be applied instead of others, so far used methods, with the exception of patients with massive pleural adhesions, which need thoracotomy.

[A rare case of cannabis arteritis]

A 24-year old woman, heavy cannabis smoker with progressive Raynauld's phenomenon and digital necrosis is presented. Systemic sclerosis and other connective tissue disorders as well as arteriosclerosis and arterial emboli were excluded with appropriate laboratory examinations. Arteriography revealed multiple forearm, palmar and digital occlusions with corkscrew-shaped vessels. Based on these characteristic arteriography and clinical findings, the diagnosis of cannabis-arteritis was finally retained. With careful necrectomy, conservative wound dressings and secondary prostacyclin therapy a complete healing of digital necrosis was observed. There was no recurrence during the 6 month-follow-up. This observation demonstrates that cannabis may represent a possible cofactor in the pathogenesis of arteritis in young smokers. Early recognition is important to avoid irreversible complications such as loss of digits.

[Periarterial sympathectomy of the radial and ulnar arteries in Raynaud's phenomenon--a preliminary study]

PURPOSE

Assessment of the post-operative results of peripheral sympathectomy in Raynaud's phenomenon.

METHODS

Six patients with therapy refractory Raynaud's phenomenon underwent a 4 cm long adventitial stripping of the radial and ulnar arteries proximal to the wrist. The nerve of Henle was followed up to the surface of the palmar arch and resected. The pre- and postoperative examinations were performed using the help of a questionnaire, telethermography and infra-red laser reflexion rheography.

RESULTS

All but two patients (two hands) were free of complaints (four patients, six hands), the three ulcers on the finger tips healed well. According to the questionnaire there was a dramatic improvement in the quality of life of the patients.

CONCLUSION

In the follow-up period of two years, there was no recurrence. Adventitial stripping of the radial and ulnar arteries and resection of the nerve of Henle proximal to the wrist have demonstrated favourable results in the treatment of therapy-resistant complaints in Raynaud's phenomenon.

Adventitial stripping of the radial and ulnar arteries in Raynaud's disease

Adventitial stripping of the palmar arch, the palmar common digital arteries, or the proper digital arteries is a last resort in the treatment of refractory primary or secondary Raynaud's phenomenon. Seven patients who had adventitial stripping of the ulnar and radial arteries proximal to the wrist and resection of the nerve of Henle, if identifiable, are presented. All of them were evaluated by telethermography, acral rheography, and a questionnaire before and after surgery. All were asymptomatic after surgery with satisfactory healing of the ulcers at the fingertips. None of them relapsed during the follow-up time of 1.5 years.

Thoracoscopic sympathectomy for palmar hyperhidrosis and Raynaud's phenomenon of the upper limb and excessive facial blushing: a five year experience

Primary hyperhidrosis of the palms, face, and axillae has a strong negative impact on social and professional life. A retrospective analysis of 40 laparoscopic transaxillary thoracic sympathectomies performed in a district general hospital over a five year period was undertaken in order to determine the effectiveness of this procedure. A postal questionnaire was sent to all patients to assess the benefit from the operation; postoperative pain and time off work were collated. Immediate failure was noted in three patients, of whom two later underwent successful reoperation. Recurrence was noted in three patients (8%). Though immediate complications were minimal, the major long term postoperative morbidity was compensatory hyperhidrosis on the back, chest, and thigh (77%) along with gustatory sweating over the face (22%). Thoracoscopic sympathectomy is a safe, effective, and minimally invasive surgical treatment for hyperhidrosis, Raynaud's phenomenon of the upper limb, and excessive facial blushing; however, the chance of long term compensatory hyperhidrosis is high.

[The hypothenar hammer syndrome]

The hypothenar hammer syndrome (HHS) is a rare form of secondary Raynaud's phenomenon in workers who frequently use the ulnar side of the palm as a hammer. Clinically the patient with HHS shows neurologic symptoms such as paresthesia, numbness and pain and signs of vascular insufficiency such as coldness, pallor, discoloration and blanching of the affected ulnar sided fingers. The diagnosis is verified by angiography, showing thrombosis or aneurysm of the distal ulnar artery. We report on the treatment and outcome of 5 patients with HHS. All patients were painfree after treatment. But with the ongoing working habit of using the hand as a hammer there is always the risk of a recurrence. Therefore the job environment has to be changed considerably and the most effort should go into prevention and prophylaxis. If the change of the working habit is not possible, the job is clearly at stake.

Endoscopic thoracic sympathicotomy for Raynaud's phenomenon

PURPOSE

For many years, thoracic sympathectomy via open surgery was not used to treat Raynaud's phenomenon because of the invasiveness of this procedure and the poor long-term outcomes associated with it. However, with the introduction of endoscopic surgery, thoracic sympathectomy (or sympathicotomy) has been performed by some surgeons as a less invasive surgical option for patients with Raynaud's phenomenon. The less invasive procedure has the possibility of emphasizing merits of sympathectomy. The purpose of this study was to reevaluate the efficacy of sympathicotomy for Raynaud's phenomenon with endoscopic technique and its range of applicability.

METHODS

Between December 1992 and August 2001, endoscopic thoracic sympathicotomy (ETS) was performed in 28 patients with Raynaud's phenomenon (of a total of 502 patients with autonomic disorders who underwent ETS) at National Kanazawa Hospital. We considered indications for surgical treatment of Raynaud's phenomenon to include severe chronic symptoms or nonhealing digital ulceration refractory to intensive medical therapy. All patients were mailed a self-assessment questionnaire after surgery to determine the immediate and long-term results of the procedure. Data from both initial and long-term follow-up examinations were obtained.

RESULTS

Fifty-four ETS procedures were performed in 28 patients. No operative mortality was seen, and no occurrence of major complications necessitated open surgery. Initial resolution or improvement of symptoms was achieved in 26 of 28 patients (92.9%). However, later in the postoperative period, symptoms recurred in 23 of 28 patients (82.1%), although no recurrence of digital ulceration was seen throughout our observation. At the final follow-up examination (median follow-up period, 62.5 months), 25 patients (89.3%) reported overall improvement of the frequency and severity of their symptoms.

CONCLUSION

Despite the high rate of recurrence, ETS clearly produced a high rate of initial relief. ETS did indeed promote healing of digital ulcers, and the procedure shows potential for reducing the severity of refractory symptoms. We consider ETS to be the method of choice for treatment of severe or refractory Raynaud's phenomenon, and especially for Raynaud's involving digital ulcer, because of its safety and efficacy.

Laparoscopic lumbar sympathectomy for lower-limb disease

BACKGROUND

The standard procedure for sympathectomy is open surgery. The oblique retroperitoneal approach is popular because it provides good visibility, albeit at the expense of requiring a long skin incision. Chemical sympathectomy has been introduced as a less invasive means of achieving sympatholysis; however, this method is also associated with a significant incidence of incomplete block and transient denervation. Laparoscopic surgery is a new approach that simplifies various surgical procedures. The aim of our report was to evaluate the benefits of endoscopic retroperitoneal surgery for lumbar sympathectomies.

METHODS

Between March 1997 and April 2000, seven patients underwent laparoscopic lumbar sympathectomy in our department (all men, with an average age or 45.1 years). The predominant presenting symptoms were unilateral pain at rest and lower-extremity coldness. Symphaectomy was performed using a retroperitoneal approach on six patients and an anterior transperitoneal approach on one patient. After laparoscopic lumbar sympathectomy, skin thermometry was carried out on all patients.

RESULTS

The postoperative skin temperature of the affected leg rose to 36.6 +/- 0.5 degrees C, as compared to 33.8 +/- 0.8 degrees C preoperatively. After laparoscopic lumbar sympathectomy, none of the patients complained of neuralgia. All patients achieved sustained symptomatic relief, and no major postoperative complications were noted.

CONCLUSIONS

Lumbar sympathectomy can be performed laparoscopically. Currently, our standard technique is the retroperitoneal approach. More clinical experience and long-term follow-up will ultimately determine if this will become the procedure of choice. However, we believe that a learning period is necessary for this technique to be fully mastered.

Ulnar artery involvement in systemic sclerosis (scleroderma)

OBJECTIVE

Microvascular disease is one of the hallmarks of systemic sclerosis (SSc, scleroderma), but macrovascular involvement also exists in some patients. Patients with SSc may have severe Raynaud's phenomenon (RP) characterized by refractory digital ulcerations. We investigated if large artery involvement, that is, ulnar artery occlusion, has a role in the development of refractory digital ulcerations, and if both screening for this involvement and revascularization of the ulnar artery occlusive disease may improve digital ulcer healing.

METHODS

A retrospective chart review was performed of 15 patients with SSc, all of whom had severe RP and digital ulceration, together with a positive Allen test and ulnar artery occlusive disease documented by angiography.

RESULTS

Women outnumbered men 2:1, with limited disease predominating (7), 5 patients having diffuse cutaneous disease and 3 overlap syndromes. All patients had positive antinuclear antibody and capillary microscopy findings consistent with SSc. Antiphospholipid antibodies were present in 4 of 6 patients tested. Tobacco use was seen in 5 patients, only 2 of whom were current smokers. All patients failed conventional medical therapy (nitrates, calcium channel blockers, antiplatelet agents) for RP and digital ulceration. Only 1/8 patients improved with stellate ganglion block, and one patient had no improvement following digital sympathectomy. Eight patients underwent ulnar artery revascularization combined with digital sympathectomy, and 8 experienced dramatic improvement in RP and healing of digital ulcers.

CONCLUSION

An Allen test should be performed routinely on all SSc patients with severe RP and refractory digital ulceration to investigate the possibility of ulnar artery occlusive disease. If suspected ulnar artery occlusion is confirmed by angiography or ultrasonography, ulnar artery revascularization with or without digital sympathectomy should be considered in patients who fail conventional medical therapy.

Medical and surgical considerations in patients with vasculitis and Raynaud's syndrome

Vascular problems in the foot are certainly common when one considers only arteriosclerosis on the macrovascular scale. The primary cause of ischemia of the foot undoubtedly is primary arteriosclerosis, whether related to smoking, diabetes, renal failure, or other causes. Vasculitis and vasospasm, in their many forms, are distinctly unusual as a cause of ischemia of the foot. These entities, nonetheless, can cause significant problems from the standpoint of symptoms and even ulceration or gangrene of the foot. This article addresses the pathophysiology of vasculitis and vasospastic problems in the foot and their management.

Surgery for ischemic pain and Raynaud's' phenomenon in scleroderma: a description of treatment protocol and evaluation of results

Although the literature suggests that palmar sympathectomy (PS) with or without vascular reconstruction may improve ischemic digital pain, fingertip ulceration, and cold intolerance in patients with scleroderma, the question regarding long-term efficacy still remains. This retrospective study of six patients (eight hands) operated on between 1995 and 1997 evaluates both early (6 months) and long-term (average, 2.5 years) outcome after PS in combination with decompression arteriolysis of the radial and ulnar arteries proximal to the wrist. When preoperative digital blood flow was inadequate based on noninvasive vascular studies and major inflow occlusion was present, vascular reconstruction was also performed when feasible. At early review, significant improvement in ischemic digital pain and moderate improvement in cold intolerance resulted in eight hands, and at final follow-up, this was sustained in seven hands. Preoperatively, digital ulcerations were present in six hands. After digital debridement and/or amputation, all wounds healed, but in one patient with bilateral disease who continued to smoke, ulcerations recurred without the need for subsequent surgery. Five of six patients were no longer dependent on narcotic analgesics, but use of vasodilator medication did not change. Five of six patients claimed significant improvement in the quality of life after surgery and reported that they would undergo the surgery again. PS in combination with radial and ulnar arteriolysis appears to be efficacious at both early and long-term review. When major inflow occlusion exists and digital blood flow is compromised, vascular reconstruction is recommended if possible. We review our treatment protocol in this complex population of patients.

[Thoracoscopic thoracic sympathectomy--personal experience]

The authors present a group of 48 thoracoscopic thoracic sympathectomies they performed in 35 patients between November 1997 and March 2000. A favourable effect was recorded in all operated patients where the defect healed or the blood supply of the upper extremities improved. Twice thoracoscopic resympathectomy was performed in a patient 15 years after classical upper thoracic sympathectomy [2] from the supraclavicular space. Twice a relapse was recorded one year after the operation. The complaints are substantially smaller than before operation. The authors emphasize the advantages of thoracoscopic thoracic sympathectomy which is associated with a minimal risk of complications.

Digital arterial occlusion in scleroderma: is there a role for digital arterial reconstruction?

A 47-year-old patient with Raynaud's phenomenon secondary to scleroderma developed long finger ischaemic pain. This was successfully treated with a palmar sympathectomy and a long finger digital artery reconstruction using a reversed small calibre vein graft between a perforator from the deep palmar arch and the radial digital artery at the level of the distal interphalangeal joint.

[The indications for and results of video thoracoscopic sympathectomy]

BACKGROUND AND OBJECTIVES

Thoracoscopic sympathectomy, for years an effective way to treat mainly palmar and axilla hyperhidrosis, experienced a revival since the application of the principles of minimally invasive surgery. We report the personal experiences of three surgeons with this technique, as well as patients' view of the outcome.

PATIENTS AND METHODS

Between January 1990 and November 1997, 73 procedures were performed in 43 patients (23 males, 20 females, mean age 38.1 years, range 15-82 years), and the outcome was prospectively studied. Palmar hyperhidrosis without axilla symptoms was the indication for the operation in 27 patients (54 sympathectomies), Raynaud's syndrome in 15 (18 sympathectomies), and causalgia in one. Thoracic ganglia 2-4 were always completely resected. Perioperative morbidity as well as patient satisfaction in the long-term course (standardized interview) 25.8 (1-77) months postoperatively were assessed.

RESULTS

The complication rate in all 73 sympathectomies was 8.2%. Only two severe incidents were observed: in one patient intermittent Horner's syndrome (1.4%) occurred, and in another severe bleeding required conversion to open surgery (1.4%). Both complications occurred in the early study phase. The initial success rate in all 27 patients with hyperhidrosis was 100%. In 30% of these cases a mild partial relapse was observed, which did not interfere with their daily activities. 53% of the patients reported compensatory and 23% gustatory sweating. 9% would have refused the operation, had they known these side effects. In all patients with Raynaud's disease the ulcerations healed completely. At the time of the interview, two patients (13%) complained of painless relapses. They too stated that they had refused the operation, if they had known about the relapses.

CONCLUSIONS

Even in the longer-term course, thoracoscopic sympathectomy is rated subjectively successful by 93% of patients after treatment of hyperhidrosis of the upper extremities, and by 87% of patients after treatment of Raynaud's disease, despite some untoward effects and partial relapses.

[Video-thoracoscopic sympathectomy in the treatment of Raynaud's disease and palmar hyperhidrosis]

BACKGROUND AND AIM

Raynaud's syndrome is a clinical entity characterised by episodic vascular spasm, digital ischemia in response to cold or emotional stimuli and hyperhidrosis. Many patients suffering from Raynaud's syndrome are successfully treated using medical therapy alone. Those patients who do not respond to medical treatment undergo surgery but the indications continue to be a source of controversy. A modern approach to thoracic sympathectomy requires a video-assisted technique. The aim of this study is to attempt to use mini-invasive type surgery to treat Raynaud's disease and hyperhidrosis in order to evaluate the real efficacy of thoracic sympathectomy in a large number of patients. The results of this method were compared for the two different pathologies in question.

METHODS

The methodology used by this study is based on instrumental and clinical tests performed before and after surgery on treated patients using a comparative criterion and with a minimum 5-year follow-up. The pre- and postoperative diagnostic tests were performed by the vascular surgery laboratory and using a C.W. Doppler and a reflected light photoplethysmograph. Capillaroscopy and laboratory evaluations relating to secondary Raynaud's disease were carried out by internist type structures. The patients enrolled in the study responded to the following criteria: primary Raynaud's disease, palmar hyperhidrosis and associated syndromes. The population came from a mixed sociodemographic background, albeit within a strictly regional zone (Sardinia). A total of 42 patients were studied. The surgical technique used consisted of the ablation of thoracic ganglia from the 2nd to the 4th.

RESULTS

The results showed a resolution of symptoms in 95% of patients treated for hyperhidrosis, whereas a 50% recidivation rate was observed in patients with Raynaud's disease alone, although symptoms were less intense. The results for Raynaud's disease were more disappointing, but it is important to remember that surgery is the ultimate choice for cases with advanced lesions which do not respond to medical treatment. Under these circumstances, the possibility of halting the evolution of the pathology represents an auspicious achievement.

CONCLUSIONS

The authors affirm that mini-invasive surgical treatment of hyperhidrosis was resolutive during a mean follow-up of 3 years. It therefore represents a valid method which causes minimum esthetic damage to the patient and the greatest functional benefit. The postoperative period is short (about 3 days) and free of major complications. There is virtually no post-surgical pain.
