Abstract
BACKGROUND In periarterial sympathectomy for intractable Raynaud phenomenon, the extent of adventitectomy and postoperative outcomes and hand perfusion assessment tools remain debatable. The authors evaluated the outcome of neurectomy of the nerve of Henle combined with ulnar tunnel release and periarterial adventitectomy in the treatment of refractory Raynaud phenomenon using objective measurements and patient-reported outcomes. METHODS Nineteen patients with 20 affected hands were prospectively enrolled and underwent the proposed procedures from 2015 to 2021. Relevant data, including Michigan Hand Outcomes Questionnaire and 36-Item Short Form health questionnaire scores, were documented for analysis during a 3-year follow-up. RESULTS The average ingress value of the three measured fingers (index, long, and ring) on indocyanine green angiography increased after surgery ( P = 0.02). The median number of ulcers decreased ( P < 0.001), and the median digital skin temperature increased ( P < 0.001). Questionnaire scores showed improvement in physical aspects, such as overall hand function ( P ≤ 0.001), activities of daily living ( P = 0.001), work performance ( P = 0.02), pain ( P < 0.001), physical function ( P = 0.053), and general health ( P = 0.048), and mental aspects, such as patient satisfaction ( P < 0.001) and mental health ( P = 0.001). The average indocyanine green ingress value of the three measured fingers significantly correlated with the patient-reported outcomes, including overall hand function ( r = 0.46, P = 0.04), work performance ( r = 0.68, P = 0.001), physical function ( r = 0.51, P = 0.02), and patient satisfaction ( r = 0.35, P= 0.03). CONCLUSIONS The proposed surgical procedures provided satisfactory outcomes, both subjectively and objectively, over a follow-up period of up to 3 years. Indocyanine green angiography may provide rapid and quantitative measurements for perioperative hand perfusion assessment. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Objective This study assesses the efficacy of distal periarterial sympathectomy in treating chronic digital ischemia by evaluating clinical outcomes of surgery. Methods A systematic literature review of distal sympathectomy for chronic digital ischemia was conducted. Data extracted included study design, patient statistics, aetiology, follow-up duration, sympathectomy level, and surgical outcomes. Results 21 studies were analysed, containing a total of 337 patients, 324 hands, and 398 digits. Patient age ranged from 23.2 to 56.6 years. Causes of ischemia included Scleroderma, Raynaud's disease, atherosclerosis/Buerger's disease, systemic lupus erythematosus/discoid lupus, undifferentiated rheumatic disorder/mixed connective tissue disease, CREST syndrome, trauma and unknown diagnoses. Common digital artery sympathectomy was mostly performed. Follow-up spanned 12-120 months. Outcomes Distal sympathectomy led to reduced pain in 94.7 % patients. Complete resolution of ulceration was seen in 73 % patients. Subsequent amputation was required in 28 % patients. Other complications were reported in 24.1 % patients. Conclusions This study indicates that distal periarterial sympathectomy may effectively treat chronic digital ischemia, offering pain relief and resolution of digital ulceration. However, risks of complications and amputation persist. Further research is required to inform patient selection and establish the optimal technique and extent of distal sympathectomy surgery, before it can be considered a valid treatment option.

Abstract
Raynaud phenomenon (RP) presents with either primary or secondary disease, and both have the potential to negatively impact patient quality of life. First-line management of RP should include lifestyle modifications in all patients. Some patients with primary RP and most with secondary RP require pharmacologic therapies, which may include calcium channel blockers, topical nitrates, phosphodiesterase 5 inhibitors, or endothelin antagonists. Additional approaches to treatment for those with signs of critical ischemia or those who fail pharmacologic therapy include botulinum toxin injection and digital sympathectomy. Herein, we describe in detail the treatment options for patients with RP as well as provide treatment algorithms for each RP subtype.

Abstract
BACKGROUND There is a strong rationale to develop locally-acting surgical treatments for digital ulcers (DUs) in patients with systemic sclerosis (SSc). Our aim was to examine the safety and efficacy of local surgical management for SSc-DU. METHODS A systematic literature review was carried out until to August 2022 using 7 different databases. Original research studies concerning adult patients with SSc-DUs, and local surgical treatments were analysed using the PICO framework. We included randomized controlled trials, prospective/retrospective studies, and case series (minimum of 3 patients) References were independently screened by two reviewers including assessment of the risk of bias using validated tools. RESULTS Out of 899, 13eligible articles were included. Autologous fat (adipose tissue AT) grafting was the surgical modality most identified (7 studies, 1 randomized controlled double blinded trial and 6 prospective open-label single arm studies). The healing rate (HR) with autologous fat grafting (4 studies) was 66-100 %. Three studies reported autologous adipose-derived stromal vascular fraction grafting: HR of 32-60 %. Bone marrow derived cell transplantation in a single study showed 100 % healing rate over 4-24 weeks. Surgical sympathectomy was examined in 3 studies, prospective without comparator with a median healing rate of 81 %. Two surgical studies (of direct microsurgical revascularisation and microsurgical arteriolysis) showed 100 % healing of ulcers, with no complications. CONCLUSION Several surgical approaches for SSc-DUs have demonstrated some degree of safety and effectiveness for DU healing. However, there are significant methodological issues. Future studies are warranted to rigorously investigate surgical interventions for SSc-DUs.

Abstract
ABSTRACT Chronic ischemia of the hands and feet is a rare medical condition that requires surgical revascularization. In particular, digital ischemia resulting from connective tissue diseases (CTDs) is among the most important manifestations that negatively affect patients' quality of life. Here, we describe a bypass graft technique for treating digital ischemia. This study aimed to share the considerable benefits of surgical intervention for CTD and present a treatment algorithm. From 2009 to 2020, bypass graft surgery was performed on 10 patients with CTD to relieve their ischemic symptoms or ulceration. Preoperative angiography was performed, and blood distribution patterns were analyzed in detail. Based on the angiographic 4-level analysis, bypass graft surgeries were performed accordingly. The postoperative follow-up was 15 to 72 months. Pain in the hands that underwent the bypass graft surgery improved immediately after surgery. All ulcerations healed and the mean time recorded for ulceration healing was 45.7 days. Here, we propose an appropriate surgical treatment algorithm for managing CTD using arterial bypass graft surgery, and its positive long-term results demonstrate that it is an appropriate option for treating digital ischemia. In conclusion, strict measures with precise preoperative planning can provide satisfactory long-term results in patients with CTD.

Abstract
Nerves not only regulate the homeostasis and energetic metabolism of normal epithelial cells but also are critical for cancer, as cancer recapitulates the biology of neural regulation of epithelial tissues. Cancer cells rarely develop in denervated organs, and denervation affects tumorigenesis, in vivo and in humans. Axonogenesis occurs to supply the new malignant epithelial growth with nerves. Neurogenesis happens later, first in ganglia around organs or the spinal column and subsequently through recruitment of neuroblasts from the central nervous system. The hallmark of this stage is regulation of homeostasis and energetic metabolism. Perineural invasion is the most efficient interaction between cancer cells and nerves. The hallmark of this stage is increased proliferation and decreased apoptosis. Finally, carcinoma cells transdifferentiate into a neuronal profile in search of neural independence. The latter is the last stage in neuroepithelial interactions. Treatments for cancer must address the biology of neural regulation of cancer.

Abstract
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.

Abstract
Although systemic sclerosis (SSc) is currently incurable, there have been recent advances in treatment. This review article begins by providing a brief background to SSc in terms of disease subtyping and autoantibodies, because both predict disease trajectory and help clinicians to select appropriate monitoring and treatment protocols. Broad principles of management are then described: ‘disease-modifying’ therapies and therapies directed at reducing disease burden and/or progression of SSc-related digital vascular disease and of internal organ involvement. Next, advances in the management of digital vasculopathy, pulmonary arterial hypertension (PAH), interstitial lung disease (ILD) and early diffuse cutaneous SSc are discussed in turn, for example: (a) increased use of phosphodiesterase inhibitors and endothelin receptor antagonists for digital vasculopathy; (b) early recognition and treatment of PAH, including with combination therapies; (c) increased use of mycophenolate mofetil and of nintedanib in ILD; and (d) immunosuppression now as standard practice in early diffuse cutaneous SSc, and autologous haematopoietic stem cell transplantation for highly selected patients with progressive diffuse disease. Finally, future challenges are discussed, including ensuring that all patients with SSc are monitored and treated according to best practice guidelines, and whenever possible giving patients the opportunity to participate in clinical trials.

Abstract
Following periarterial sympathectomy, patients with recurrent digital ischemia due to vasospastic or vaso-occlusive disease have few remaining treatment options. We performed a retrospective review from 1997 to 2019 to determine the safety and efficacy of revision periarterial sympathectomy. Eleven patients were identified who underwent revision periarterial sympathectomy, performed on average 84 months after their initial procedure. Preoperatively, all patients had worsening ischemic pain and five had non-healing digital ulcers. Revision digital periarterial sympathectomy alone was performed in seven patients, while four had a more extensive sympathectomy. Mean follow-up after revision was 23 months (range 3 to 76). Eight patients had symptomatic improvement and four healed their digital ulcers. Three patients developed new ulcers during follow-up, of which two healed with conservative management and one required three digital amputations. Revision periarterial sympathectomy is effective in providing symptomatic improvement and digital ulcer healing with minimal postoperative complications.Level of evidence: IV.

Abstract
OBJECTIVES This study investigated the effect of very low concentrations of ethanol on artery and vein anastomosis. Also, it was aimed to determine the appropriate ethanol concentration to be used in vasospasm. METHODS Rats were divided into five groups of eight rats, each group, as follows: Group i: saline; Group ii: 2.5% ethanol; Group iii: 5% ethanol; Group IV: 7.5% ethanol; and Group V: 10% ethanol. During the femoral artery and vein anastomosis, 1ml of the agent was used for irrigation in each group. Vessel diameters were measured before the anastomosis, at the fifth and 15th minutes, and the third week after the anastomosis. Histopathological samples were taken in the third week. RESULTS In Groups ii and iii, the mean vessel diameters were found to increase 15th minute. Also observed was an increase in mean vessel diameter that continued in the third week. Although acute vasodilation was detected in Groups IV and V, arterial and venous thrombosis was observed in the third week. Intima and media thickness decreased in Group ii, while it increased in Group iii. Perivascular inflammation and fibrosis increased as the ethanol concentration increased. CONCLUSION 2.5% ethanol causes acute and prolonged vasodilation and does not cause endothelial cell damage, perivascular inflammation, and fibrosis. 2.5% ethanol will be a powerful alternative use in many situations that occur with vasospasm.

Abstract
Sympathectomy of arteries has been adopted for the treatment of peripheral arterial disease and Raynaud's disease. However, the exact route for sympathetic axons to reach peripheral arteries awaits further investigation that could pave the way for development of new surgical strategies. In this study, saphenous neurovascular bundles from 10 neonatal Sprague-Dawley rats first were harvested for whole-mount immunostaining to show sympathetic innervation pattern of the artery. Secondly, 40 Sprague-Dawley male rats weighing 350 to 400 g were assigned to five groups, receiving either sham, perivascular sympathectomy, nerve-artery separation, nerve transection in the saphenous neurovascular bundle, or lumbar sympathectomy surgery that removes the lumbar sympathetic trunks. Immediately after surgery, the arterial perfusion and diameter were measured using laser speckling contrast imaging, and 1 week later the saphenous neurovascular bundles were harvested for immunostaining using antibodies against TH, neuron-specific β-tubulin (Tuj 1), and α-SMA to show the presence or absence of the TH-immuopositive staining in the adventitia. The differences among the five groups were determined using one-way analysis of variance (ANOVA). We found that an average of 2.8 ± 0.8 branches with a diameter of 4.8 ± 1.2 μm derived from the saphenous nerve that morphed into a primary and a secondary sympathetic trunk for innervation of the saphenous artery. Nerve-artery separation, nerve transection, and lumbar sympathectomy could eradicate TH-immunopositive staining of the artery, resulting, respectively, in a 12%, 36%, and 59% increase in diameter (P < .05), and a 52%, 63%, and 201% increase in perfusion compared with sham surgery (P < .01). In contrast, perivascular sympathectomy did not have a significant impact on the TH-immunopositive staining, the diameter, and perfusion of the distal part of the artery (P > .05). We conclude that the sympathetic innervation of an artery derives from segmental branches given off from its accompanying nerve. Nerve-artery disconnection is a theoretic option in sympathectomy of an artery.

Abstract
Raynaud phenomenon (RP) is a condition causing vasospasm in the fingers and toes of patients that can have a significant negative impact on quality of life. This can lead to pain, ulceration, and possible loss of digits. Several pharmacological options are available for treatment. However, RP can often be refractory to traditional modalities, leaving surgery or injections as the next available options. This article provides a review and update on the use of botulinum toxin as an effective therapy for the treatment of RP refractory to medical management.

Abstract
Posttraumatic hand injuries from crush injury, infusion, or iatrogenic vascular cannulation can cause ischemic finger damage that can progress to necrosis and digital amputation. Botulinum toxin type A (Botox) improves blood flow in chronic vasospastic disorders of the hand. Botox's efficacy in salvaging ischemic loss in digits in acute traumatic and iatrogenic injury has not been previously reported. From February of 2015 to December of 2016, 11 patients at a Level I trauma center (West Virginia University) presented to the hand surgery service with early ischemic injury and vascular compromise to hand and fingers as a result of crush, direct drug injection, or proximal arterial injury from drug injection or catheterization. Before 2015, all patients with vascular compromise were treated with standard protocol. After January of 2016, patients were treated with additional injection of 80 to 100 U of Botox into the palm and wrist. Before administration of Botox, six patients with vascular compromise of one or more fingers were treated with a conservative protocol and 83 percent had amputation of necrotic digits. After January of 2016, five patients with ischemia were treated with Botox into the palm and proximal arteries. All Botox-treated digits were preserved (100 percent salvage). Pain scores were lower in Botox-treated fingers. We conclude that (1) in the acute traumatic vascular hand injury, early Botox injection markedly increases digital salvage; (2) direct nerve effects after Botox injections improve postinjury pain scores; and (3) early use of Botox in finger injuries is our standard approach to impending ischemia in the hand.

Abstract
Selective periarterial sympathectomy in Raynaud phenomenon (RP) has not been adequately studied as there was no reliable method to evaluate outcomes. However, dynamic Doppler ultrasonography may have clinical value in the management and follow-up of patients with RP; but few reports describe using the device to assess surgical outcomes. Here, we report a case of successful digital sympathectomy in a single digit and the postoperative evaluation using ultrasonography. A 23-year-old patient with secondary RP underwent surgery targeting both common digital artery (ulnar side) and the proper digital artery (radial side). The procedure yielded immediate pain relief and the improvement of recurrent fingertip ulceration. The 1-year postoperative assessment with dynamic Doppler ultrasonography using a hockey-stick probe was performed with a cold provocation test and revealed peak systolic velocity improvement comparable to the nontreated ulnar side but prominent fibrosis on the radial aspect. We anticipate that Doppler ultrasonography may be an effective tool for the postoperative assessment of patients who underwent digital sympathectomy for treatment of RP.

Abstract
Background: Chronic hand ischemia refers to progressive, non-acute ischemic symptoms such as cold intolerance, rest pain, ulceration, tissue necrosis, and digit loss and poses a significant challenge in management. Conservative treatment begins with medical optimization and pharmacologic therapy, but when symptoms persist, surgical intervention may be required. Various operations exist to improve circulation including sympathectomy, arterial bypass, or venous arterialization. The purpose of this study is to systematically review published outcomes and present our experience with each surgical technique.Methods: A systematic review of literature regarding surgical treatment of chronic hand ischemia published between 1990 and 2016 was conducted using PRISMA guidelines. A retrospective-review of surgical interventions for chronic hand ischemia from 2010 to 2016 was then conducted. Primary outcomes included improvement in pain, wound-healing, and development of new ulcerations.Results: The review included 38 eight studies, showing all three techniques were effective in treating chronic hand ischemia. Sympathectomy had the lowest rate of new ulcerations (0.8%); bypass had the highest rate of healing existing ulcerations (89%). Arterialization was associated with consistent pain improvement pain (100%) but more complications (30.8%). Our series included 18 patients with 21 affected hands, 18 sympathectomies, 6 ulnar artery bypasses, and 1 arterialization. Most hands had improvement of wounds (89.5%) and pain (78.9%). No patients developed new ulcerations, but one required secondary amputation.Conclusions: When conservative measures fail to improve chronic hand ischemia, surgical intervention is an effective last line treatment. An algorithmic approach can determine the best operation for patients with chronic hand ischemia.

Abstract
Raynaud's phenomenon is highly prevalent in the general population. The optimal medical management for patients with severe Raynaud's phenomenon remains unclear. Venous arterialization (VA) may be considered as a salvage procedure when no distal vessels are available for vascular reconstruction. Surgical treatments for lymphedema, including lymphovenous anastomosis (LVA), are becoming popular alternatives to conservative therapy. Here, we report on a patient with comorbid primary Raynaud's phenomenon and lymphedema in whom both VA and LVA were performed. The patient was a 60-year-old woman with an edematous right upper limb and pain and cold sensitivity in the middle, ring, and small fingers that was refractory to medication. Indocyanine green lymphography and computed tomography angiography suggested coexistence of lymphedema and primary Raynaud's phenomenon. VA and LVA were performed to reduce the risks of cellulitis and amputation. Computed tomography angiography was performed regularly after surgery to examine the arterialized venous system and Doppler echography to search for developing branches. Five months later, three branches of the arterialized veins that flowed proximally at the level of the hand and wrist were ligated. By around 1 year after surgery, the lymphedema index in the affected upper limb had improved from 116 to 103 and the patient's numerical rating scale score for intractable pain and cold sensitivity had improved from 6-7 to 1-2. We believe that the combination of VA and LVA in the early stages of primary Raynaud's phenomenon and lymphedema was effective in this case.

Abstract
Raynaud's phenomenon can be either primary (idiopathic) or secondary to underlying disease including systemic sclerosis. Primary Raynaud's phenomenon is very common, affecting approximately 3%-5% of the general population. Although much rarer, systemic sclerosis-related Raynaud's phenomenon can be particularly severe, progressing to digital ulceration in approximately 50% of patients. Raynaud's phenomenon can have a major impact on quality of life. This review has a focus on the systemic sclerosis-related Raynaud's phenomenon (which is the most researched form of Raynaud's phenomenon and probably the most challenging to treat) and on recent advances. Epidemiology (including transition from 'isolated' to systemic sclerosis-related Raynaud's phenomenon), pathogenesis, diagnosis and assessment are discussed, followed by the treatment of both 'uncomplicated' and 'complicated' Raynaud's phenomena (i.e. Raynaud's phenomenon which has progressed to digital ulceration and/or critical ischaemia). Finally, some of the major challenges for the next 5-10 years are highlighted.

Abstract
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.

Abstract
Raynaud's phenomenon (RP) is relevant to the rheumatologist because it may signify an underlying connective tissue disease and also because it can be very challenging to treat, especially when it has progressed to digital ulceration or critical ischaemia. This review article discusses diagnosis (does this patient have an underlying connective tissue disease?), including the role for nailfold capillaroscopy, and treatment. Management of 'uncomplicated' RP is first described and then treatment of RP complicated by progression to digital ulceration or critical ischaemia, highlighting recent advances (including phosphodiesterase type 5 inhibition, and endothelin 1 receptor antagonism) and the evidence base underpinning these. Possible future therapies are briefly discussed.

Abstract
Cutaneous nerves have branches called vascular branches (VBs) that reach arteries. VBs are thought to be involved in arterial constriction, and this is the rationale for periarterial sympathectomy as a treatment option for Raynaud's disease. However, the branching patterns and distribution areas of the VBs remain largely unclear. The aim of the present study was to investigate the anatomical structures of the VBs of the cutaneous nerves. Forty hands and forearms were examined to assess the branching patterns and distribution areas of the VBs of the superficial branch of the radial nerve (SBRN), the lateral antebrachial cutaneous nerve (LACN), the medial antebrachial cutaneous nerve (MACN), and the palmar cutaneous branch of the ulnar nerve (PCUN). VBs reaching the radial and ulnar arteries were observed in all specimens. The branching patterns were classified into six types. The mean distance between the radial styloid process and the point where the VBs reached the radial artery was 34.3 ± 4.8 mm in the SBRN and 38.5 ± 15.8 mm in the LACN. The mean distance between the ulnar styloid process and the point where the VBs reached the ulnar artery was 60.3 ± 25.9 mm in the MACN and 43.8 ± 26.0 mm in the PCUN. This study showed that the VBs of the cutaneous nerves have diverse branching patterns. The VBs of the SBRN had a more limited distribution areas than those of the other nerves. Clin.

Abstract
Raynaud phenomenon (RP) is a transient digital ischemia that occurs after exposure to cold temperature or emotional distress. It presents with a triphasic course: the initial white phase is followed by cyanotic discoloration and, subsequently, erythema. The attacks may be associated with pain, paresthesia, and complicate with nonhealing ulceration often leading to amputation. To date, there are no clear-cut therapeutic guidelines and many medications are used off-label. Encouraging results were reported with the use of botulinum neurotoxin-A (BoNT-A). However, there is still ongoing debate regarding indications, contraindications, best injection technique, and mechanism of action. The aim of this study was to address these issues by providing an up-to-date and detailed overview of the use of BoNT-A in RP.A PubMed database search was conducted. The available studies and techniques were evaluated and compared.The search yielded a total of 29 studies. Ten papers, published between 2004 and 2014, were considered relevant. A total of 128 patients underwent BoNT-A injections. Seventy-five percent to 100 % of the patients reported pain reduction after treatment. Healing of ulcers was reported in 75% to 100% of the affected patients. The most common complication was temporary hand weakness, with an average incidence of 14.1%. Injections targeting the neurovascular bundle at or slightly proximal to the A1 pulley were the most commonly performed.Botulinum neurotoxin-A injection proved to be a valid approach in both primary and secondary RP. The available evidence shows the achievement of both symptomatic and functional improvements in this debilitating condition. However, the patient should be adequately informed about the risk of transient hand weakness.

Abstract
INTRODUCTION Raynaud's phenomenon (RP) can be either primary (idiopathic) or secondary to a number of different diseases/conditions, when vasopasm can be superimposed upon structural vascular abnormality or a hyperviscosity state and may then lead to severe ischaemia with tissue damage. Treatment must be tailored to the individual. Areas covered: This review discusses how increased understanding of the pathogenesis of RP has driven and is driving new approaches to therapy, and how we are now better able to predict which patients presenting with RP are likely to have an underlying disease requiring specific intervention. Medline searches (1946 to August 2016) were conducted for 'Raynaud's' in combination with relevant terms including different drugs. All papers identified were English language, with abstracts. Expert commentary: Randomised controlled trials of RP present particular challenges. The major aim must continue to be development of safe, effective treatments for patients across the spectrum of RP.

Abstract
The International Society of Reconstructive Neurosurgery (ISRN) is an "open" multidisciplinary Society in evolution. Many different members of the Society inspire new trends in many different neurosurgical fields, all dealing with neurosurgical reconstruction.Spine and peripheral nerve reconstructive surgery, central nervous system revascularization (via surgery and interventional radiology), neuromodulation, bioengineering, and transplantation are recent tools used to promote reconstruction, restoration, and rehabilitation.These are the three key words of our creed and all fulfill the aim of the ISRN, dealing with mechanical, morphological, and functional restoration.Spinal, functional, vascular, radiological, and oncologic neurosurgeons are those to whom our proposals are addressed, along with biologists, bioengineers, anatomists, physiologists, and physiotherapists, who are precious and irreplaceable inspirers.

Abstract
PURPOSE Periarterial sympathectomy is a treatment option for patients with systemic sclerosis (SSc) suffering from digital vasculopathy. Despite potential benefits of ulcer healing, pain improvement, and amputation prevention, this operation appears to be infrequently performed. The aims of our study are as follows: (1) to assess national digital sympathectomy rates in patients with SSc and (2) to improve our understanding of referring physicians' perceptions of operative management and access to hand surgeons. Our hypothesis is that rheumatologists' practices largely influence their referral patterns for digital sympathectomy. METHODS To determine the rates and demographics of hospitalized patients with SSc who had undergone digital sympathectomy, we queried the Nationwide Inpatient Sample from 2006 to 2010. Additionally, we mailed a self-administered survey to a national sample of 500 board-certified rheumatologists to elicit their practice patterns and perceptions of digital sympathectomy. Using logistic regression, we analyzed potential predictor variables associated with rheumatologists performing the following: (1) routinely counseling patients about digital sympathectomy and (2) expressing the desire to refer these patients for operative evaluation. RESULTS Of 348,539 hospitalizations associated with a diagnosis of SSc, only 0.2% were for digital sympathectomy. Our questionnaire revealed that only 50% of rheumatologists routinely counseled, whereas 67% expressed the desire to refer. Factors associated with increased rheumatologists' interest in surgical management for patients with SSc included positive perception of the operation's efficacy, comfort with postoperative management, and interdisciplinary relationship with a hand surgeon. DISCUSSION Critical components to increasing appropriate utilization of digital sympathectomy include enhancing rheumatologists' understanding of the operation, comfort with postoperative management, and promoting strong, interdisciplinary relationships with hand surgeons. Increasing education and awareness, as well as establishing a solid referral network of hand surgeons may thereby improve patient access to digital sympathectomy.
