Guidelines for management of actual or suspected inadvertent intra-arterial injection of sclerosants.

BACKGROUND: Inadvertent intra-arterial injection of sclerosants is an uncommon adverse event of both ultrasound-guided and direct vision sclerotherapy. This complication can result in significant tissue or limb loss and significant long-term morbidity. OBJECTIVES: To provide recommendations for diagnosis and immediate management of an unintentional intra-arterial injection of sclerosing agents. METHODS: An international and multidisciplinary expert panel representing the endorsing societies and relevant specialities reviewed the published biomedical, scientific and legal literature and developed the consensus-based recommendations. RESULTS: Actual and suspected cases of an intra-arterial sclerosant injection should be immediately transferred to a facility with a vascular/interventional unit. Digital Subtraction Angiography (DSA) is the key investigation to confirm the diagnosis and help select the appropriate intra-arterial therapy for tissue ischaemia. Emergency endovascular intervention will be required to manage the risk of major limb ischaemia. This includes intra-arterial administration of vasodilators to reduce vasospasm, and anticoagulants and thrombolytic agents to mitigate thrombosis. Mechanical thrombectomy, other endovascular interventions and even open surgery may be required. Lumbar sympathetic block may be considered but has a high risk of bleeding. Systemic anti-inflammatory agents, anticoagulants, and platelet inhibitors and modifiers would complement the intra-arterial endovascular procedures. For risk of minor ischaemia, systemic oral anti-inflammatory agents, anticoagulants, vasodilators and antiplatelet treatments are recommended. CONCLUSION: Inadvertent intra-arterial injection is an adverse event of both ultrasound-guided and direct vision sclerotherapy. Medical practitioners performing sclerotherapy must ensure completion of a course of formal training (specialty or subspecialty training, or equivalent recognition) in the management of venous and lymphatic disorders (phlebology), and be personally proficient in the use of duplex ultrasound in vascular (both arterial and venous) applications, to diagnose and provide image guidance to venous procedure. Expertise in diagnosis and immediate management of an intra-arterial injection is essential for all practitioners performing sclerotherapy.

Skin hyperpigmentation after sclerotherapy with polidocanol: A systematic review.

Skin hyperpigmentation after sclerotherapy with polidocanol-containing sclerosants is a common local side effect. Sclerotherapists should be familiar with factors that trigger hyperpigmentation after sclerotherapy with polidocanol-containing sclerosants. A systematic literature review of works reporting hyperpigmentation after sclerotherapy for telangiectasias, reticular veins, side branches and truncal varices with polidocanol-containing sclerosants was performed. Reported incidence rates, follow-up periods and potentially triggering factors were assessed and analysed. The search yielded 1687 results; of these, 27 reports met the inclusion criteria. The incidence of hyperpigmentation seemed to increase with higher concentrations of polidocanol and was more evident after sclerotherapy for epifascial veins than for intrafascial truncal veins when the polidocanol concentration was more than 0.25%. Regarding sclerotherapy for telangiectasias and reticular veins, the incidence of hyperpigmentation ranged between 2% and 25% for polidocanol 0.25% (liquid and foam), between 12.5% and 67.9% for polidocanol 0.5% (liquid and foam) and between 13% and 73% for polidocanol 1% (liquid and foam). Regarding truncal veins, the incidence ranged from 7% to 45.8% for polidocanol 1% (liquid and foam), from 16% to 17% for polidocanol 2% (foam) and from 7.4% to 32.5% for polidocanol 3% (liquid and foam). Regarding the treatment of side branches, the incidence of hyperpigmentation ranged from 5.6% to 53% for both foam and liquid sclerotherapy. Regarding the duration of hyperpigmentation, there are few data describing reticular veins and telangiectasias. Hyperpigmentation persisting for more than 6 months has been reported to have an incidence of up to 7.5%. Hyperpigmentation persisting for more than 1 year after foam polidocanol 1%-3% treatment for truncal veins has an incidence ranging from 8.1% to 17.5%. Other factors such as higher volumes and compression therapy after treatment seem to have a minor influence. Data regarding hyperpigmentation after polidocanol-related sclerotherapy are poor and should be improved by higher-quality research.

Reliability Assessment and Validation of the Skin Hyperpigmentation Index Compared to the Physician Global Assessment Score.

BACKGROUND: The skin hyperpigmentation index (SHI), a new objective method for measuring skin hyperpigmentation, needs validation. OBJECTIVE: To gain evidence of the reliability and validity of the SHI. METHODS: Fifteen raters were divided into 3 groups (5 dermatologists, 5 nondermatologist physicians, and 5 nonphysician clinicians). Each rated 5 pigmented mole lesions with mild-to-severe hyperpigmentation to determine intra- and interrater reliability. All raters photographed the lesions and rated them using the subjective Physician Global Assessment (PGA) score. The same photographs were then assessed based on automatic computer measurement software using the online SHI tool (https://shi.skinimageanalysis.com). RESULTS: The SHI reliability was excellent for all intra- and interrater assessments, while most PGA assessments showed good intra- and interrater agreement. Between-group reliability was excellent for SHI, while moderate-to-good for PGA evaluations. Concordance between the SHI and PGA assessments was strong across all groups of assessors. CONCLUSION: There is evidence that the SHI is a reliable instrument for measuring skin hyperpigmentation, and can be used by nonexperienced clinicians.

Fifth metatarsal scarf osteotomy without implant fixation.

Fifth metatarsal shaft osteotomy has demonstrated efficacy for bunionette. We adapted screwless 1st metatarsal scarf osteotomy to the 5th ray. The technique consists in short osteotomy, translation and diaphyseal bone-suture. We report the first 25 operated feet, with mean AOFAS score 58.4 preoperatively and 94.9 postoperatively at a mean 25 months' follow-up. These results were comparable to reported data, whatever the deformity.

The skin hyperpigmentation index: An objective method of measuring the intensity of hyperpigmentation after sclerotherapy.

Skin hyperpigmentation in chronic venous insufficiency and as a side effect in vein treatments are of great importance for the affected individuals. There are only a few qualitatively limited methods that allow its quantification. Previous techniques to develop a reliable scientific approach to quantification have failed due to the lack of standardized conditions including differences in lighting, distances and equipment. A newly developed measuring method, the "skin hyperpigmentation index", enables a fully automated and standardized quantification of skin hyperpigmentation with dermatoscopic images. The skin hyperpigmentation index defines the ratio of two scores, namely hyperpigmented skin of the affected area and normal sun protected skin from the same patient. This results in a range from 1 (no pigmentation) to 4 (maximum pigmentation). For a practical evaluation of the score, a free skin hyperpigmentation index calculator can be used online, which is accessible to all practitioners (https://shi.skinimageanalysis.com/). The skin hyperpigmentation index is a fully automated method for the quantitative assessment of skin pigmentation which can easily be applied to any skin type with any type of hyperpigmentation. This allows a simple, fast, and standardized quantification of skin hyperpigmentation and is useful for monitoring the progress and planning of whitening therapy.

Right Atrial Intimal Sarcoma on 18F-FDG PET/CT.

A right atrial mass was discovered with transthoracic cardiac ultrasound in a complaint-free, 81-year-old man at his yearly cardiological checkup. Further investigation of the mass with transesophageal cardiac ultrasound showed a well-defined nodular mass of approximately 3 × 3 cm, in close proximity to the posterior wall of the right atrium. The patient underwent an F-FDG PET/CT, which showed a right atrial mass with very high FDG uptake, suggesting a malignant process. The mass was surgically removed, and anatomopathological assessment revealed an intimal sarcoma, which is a very malignant tumor and an extremely rare occurrence at this location.

Bloodpool SPECT as part of bone SPECT/CT in painful total knee arthroplasty (TKA): validation and potential biomarker of prosthesis biomechanics.

PURPOSE: To compare bloodpool SPECT with planar imaging in bone SPECT/CT of painful total knee arthroplasty (TKA) with respect to inter-rater agreement, confidence, prosthesis outcome, and biomechanical functioning. METHODS: Retrospective study of bloodpool SPECT and planar control images. Four raters used the validated Bruderholz scheme and a 5-point scale to grade uptake. Inter-rater agreement and overall confidence scores were calculated. Variable cluster analysis was performed to identify patterns of uptake, and associations between patterns and prosthesis outcome and biomechanical functioning were examined. RESULTS: In all, 55 knees in 43 patients were analyzed (median follow-up 17 months; revision rate 21.8%). SPECT significantly improved inter-rater agreement in 24% of regions (all P < 0.05) and overall confidence by 20% (P < 0.001). Regional uptake cluster analysis showed improved antero-posterior separation with SPECT, and distinct patterns associated with prosthesis survival in lateral femoral (P = 0.041) and medial tibial (P < 0.001) regions. The prognostic value of SPECT outperformed planar imaging for tibial (P < 0.001), patellar (P = 0.009), and synovial (P = 0.040) assessment. Internal femoral malrotation resulted in increased uptake in posteromedial (P = 0.042) and anterolateral (P = 0.016) femoral, and lateral patellar (P = 0.011) regions. Internal tibial malrotation increased uptake in posterolateral (P = 0.026) and posteromedial tibial (P = 0.005), and medial patellar regions (P = 0.004). Bloodpool SPECT improved the prognostic value of late-phase SPECT/CT for the assessment of the medial tibial region. CONCLUSIONS: Bloodpool SPECT outperforms planar assessment of painful TKAs and the identification of distinct uptake patterns make it a potentially clinically relevant biomarker of prosthesis survival and biomechanical functioning.

The Cerebrospinal Fluid Aß1-42/Aß1-40 Ratio Improves Concordance with Amyloid-PET for Diagnosing Alzheimer's Disease in a Clinical Setting.

BACKGROUND: Evidence suggests that the concordance between amyloid-PET and cerebrospinal fluid (CSF) amyloid-ß (Aß) increases when the CSF Aß1-42/Aß1-40 ratio is used as compared to CSF Aß1-42 levels alone. OBJECTIVE: In order to test this hypothesis, we set up a prospective longitudinal study comparing the concordance between different amyloid biomarkers for Alzheimer's disease (AD) in a clinical setting. METHODS: Seventy-eight subjects (AD dementia (n = 17), mild cognitive impairment (MCI, n = 48), and cognitively healthy controls (n = 13)) underwent a [18F]Florbetapir ([18F]AV45) PET scan, [18F]FDG PET scan, MRI scan, and an extensive neuropsychological examination. In a large subset (n = 67), a lumbar puncture was performed and AD biomarkers were analyzed (Aß1-42, Aß1-40, T-tau, P-tau181). RESULTS: We detected an increased concordance in the visual and quantitative (standardized uptake value ratio (SUVR) and total volume of distribution (VT)) [18F]AV45 PET measures when the CSF Aß1-42/Aß1-40 was applied compared to Aß1-42 alone. CSF biomarkers were stronger associated to [18F]AV45 PET for SUVR values when considering the total brain white matter as reference region instead of cerebellar grey matterConclusions:The concordance between CSF Aß and [18F]AV45 PET increases when the CSF Aß1-42/Aß1-40 ratio is applied. This finding is of most importance for the biomarker-based diagnosis of AD as well as for selection of subjects for clinical trials with potential disease-modifying therapies for AD.

Anomalous intraosseous venous drainage: Bone perforators?

Objectives Anomalous intraosseous venous drainage is a rare and almost unknown entity; only 14 cases have been reported in the literature and 4 mentioned in textbooks. We report the characteristics of 35 further cases observed in 32 patients. Method After the presentation of two cases at the congress of the French Society of Phlebology in Paris (2013), 12 colleagues joined to present a large series of so-called bone perforators observed in their practice, all identified with at least a duplex investigation. Results Thirty-two patients suffering from varicose veins and/or skin changes (C2-C6) associated with a bone perforator of the tibia (with bilateral anomalies in three) are reported: 19 females and 13 males, average age 56.9. The majority of the affected legs were symptomatic (30/35). Bone perforator was an isolated finding in 27/35 legs. In three cases, the investigations revealed that the venous reflux in the bone originated from an incompetent posterior tibial vein. Conclusions We suggest the name of "bone perforators" for an anomalous tibial intraosseous venous drainage, feeding varicose veins, and in more advanced stages lipodermatosclerosis and leg ulcers. Most of them were successfully treated with surgery or sclerotherapy.

Konsensuspapier zur symptomorientierten Therapie der chronischen Venenerkrankungen.

HINTERGRUND: Chronische Venenerkrankungen sind eine Volkskrankheit. Venöse Symptome wie Schwellungs- und Schweregefühl können bereits früh ohne sichtbaren Befund auftreten und werden als belastend erlebt. Ein Fortschreiten im Sinne einer objektivierbaren Varikose bzw. chronischen venösen Insuffizienz schränkt die Lebensqualität erheblich ein. METHODIK: Pubmed-gelistete Publikationen sowie relevante Leitlinien zur Therapie chronischer Venenkrankheiten bilden die Basis der vorliegenden Konsensusempfehlungen. Inkludiert in die Bewertung wurden ausschließlich aussagekräftige randomisierte Studien (RCT) und Übersichtsarbeiten (Reviews/Metaanalysen). ERGEBNISSE: Die symptomorientierte Behandlung chronischer Venenerkrankungen stützt sich auf drei Säulen mit nachgewiesener Wirksamkeit: invasive Therapie, Kompressionstherapie und orale medikamentöse Therapie. Gemäß Empfehlungen aktueller Leitlinien sollte zunächst eine Sanierung des venösen Gefäßbetts erwogen werden, um einen störungsfreien venösen Blutfluss wiederherzustellen und Symptome und pathologische Veränderungen zu beseitigen oder zu bessern. Ist ein invasiver Eingriff nicht möglich bzw. nicht erwünscht oder bestehen nach einem Eingriff noch Restsymptome, gilt es, die symptomatischen Therapieoptionen optimal auszuschöpfen. Kompressionstherapie und medikamentöse Therapie können allein oder in Kombination angewendet werden. Welche Strategie den größten Erfolg verspricht, ist individuell zu entscheiden. SCHLUSSFOLGERUNGEN: Chronische Venenerkrankungen sollten auf der Basis der individuellen pathophysiologischen Störung behandelt werden. Sie symptomorientierte Behandlung chronischer Venenerkrankungen fußt auf der invasiven Therapie, der Kompressionstherapie und der medikamentösen Therapie. Bei der Indikationsstellung sind objektive Symptome ebenso wie subjektive Beschwerden zu berücksichtigen.

Consensus statement on the symptom-based treatment of chronic venous diseases.

BACKGROUND: Chronic venous diseases are very common. Early symptoms such as a sensation of swelling and heaviness may occur without objectifiable findings, but are nevertheless perceived as bothersome. Progressive disease - marked by varicose veins and symptoms of chronic venous insufficiency - is associated with considerable impairment in quality of life. METHODS: The present consensus recommendations are based on publications in Pubmed-listed journals as well as relevant international therapeutic guidelines on chronic venous diseases. Only conclusive randomized controlled trials (RCTs) and review articles/meta-analyses were included. RESULTS: Symptom-based treatment of chronic venous diseases is based on three therapeutic pillars with proven efficacy: invasive therapy, compression therapy, and oral pharmacological treatment. According to current therapeutic guidelines, invasive procedures aimed at restoring unimpaired venous blood flow as well as improving or eliminating pathological changes should be the first-line approach. If an invasive approach is infeasible or undesirable, or if symptoms persist following a therapeutic intervention, optimal use of symptom-based treatment options is recommended. Compression and pharmacological therapy may each be used as sole treatment or in combination. To guarantee maximum therapeutic success, individual treatment decisions should be made on a case-by-case basis. CONCLUSIONS: Chronic venous diseases should be treated on the basis of individual pathophysiological disturbances. Symptom-based treatment of chronic venous disorders encompasses invasive therapy, compression therapy, and oral pharmacological therapy. Considerations in choosing the appropriate treatment option should include both objective signs as well as subjective symptoms.

Three Different Locations of a Sentinel Node Highlight the Importance of Performing a Sentinel Node Biopsy in Breast Cancer Recurrence.

A local breast cancer recurrence or a new breast cancer in the previously treated breast is a staging challenge. Staging is important to tailor the local and the systemic treatment. Earlier treatment(s) can disrupt the primary lymphatic drainage. After the disruption, new lymphatic drainage pathways are often created. The identification of these new pathways together with their sentinel node(s) (SN) is important for retreatment. A fluorodeoxyglucose positron emission tomography-computerized tomography could be useful to identify the involved node(s), but, unfortunately, there is no evidence to support this. Ideally, in the case of a recurrence, an SN biopsy should be performed in order to identify the "new" draining lymph node(s). This new draining SN(s) can be located in unexpected places, and tumor invasion will lead to a change in the management.

Sclerotherapy in tumescent anesthesia of reticular veins and telangiectasias.

BACKGROUND: Some leg telangiectasias may be refractory to treatment, including sclerotherapy and lasers. OBJECTIVE: To describe the innovative Sclerotherapy in Tumescent Anesthesia of Reticular veins and Telangiectasias (START) approach to achieving good results in such patients, which also proves effective in treating reticular veins. METHOD: Because compression enhances the rate of success of sclerotherapy of C1 veins (telangiectasias and reticular), Ringer solution (with or without lidocaine-epinephrine) was injected subcutaneously before, during, or immediately after sclerotherapy of therapy-refractory C1 veins. This tumescence ensures an intratissular compression of the injected vessels for at least 1 hour. RESULTS: In the last 6 years, we have treated more than 300 patients. Telangiectasias that had resisted several previous treatments faded or disappeared in the majority of the cases treated, but the rate of complications (pigmentation, necrosis of small areas, and tiny scars) was higher than with usual sclerotherapy. CONCLUSION: Developed after observing the good results achieved by perioperative sclerotherapy of telangiectasias during ambulatory phlebectomy, the START technique is an effective and economic treatment of therapy-resistant telangiectasias, although because the rate of complications is higher than with usual sclerotherapy of C1 veins, it should be performed only by experienced phlebologists and only on therapy-refractory vessels.

Reticulate eruptions: Part 2. Historical perspectives, morphology, terminology and classification.

Reticulate eruptions of vascular origin may represent an underlying arterial, venous, microvascular or combined pathology. In the presence of arterial pathology, individual rings are centred around ascending arterial vessels that supply the corresponding area of skin within an arterial hexagon that clinically presents with a blanched centre. Confluence of multiple arterial hexagons generates a stellate (star-like) pattern. In the presence of a primary venous pathology, individual rings correspond to the underlying reticular veins forming multiple venous rings. Focal involvement of a limited number of vessels presents with a branched (racemosa) configuration while a generalized involvement forms a reticulate (net-like) pattern. 'Livedo' refers to the colour and not the pattern of the eruption. Primary livedo reticularis (Syn. cutis marmorata) is a physiological response to cold and presents with a diffuse blanchable reticulate eruption due to vasospasm of the feeding arteries and sluggish flow and hyperviscosity in the draining veins. Livedo reticularis may be secondary to underlying conditions associated with hyperviscosity of blood. Livedo racemosa is an irregular, branched eruption that is only partially-blanchable or non-blanchable and always signifies a pathological process. Retiform purpura may be primarily inflammatory with secondary haemorrhage or thrombohaemorrhagic, as seen in disseminated intravascular coagulopathy.

A double-blind, randomized study comparing pure chromated glycerin with chromated glycerin with 1% lidocaine and epinephrine for sclerotherapy of telangiectasias and reticular veins.

BACKGROUND: Chromated glycerin (CG) is an effective, although painful, sclerosing agent for telangiectasias and reticular leg veins treatment. OBJECTIVE: To determine pain level and relative efficacy of pure or one-third lidocaine-epinephrine 1% mixed chromated glycerin in a prospective randomized double-blind trial. METHOD: Patients presenting with telangiectasias and reticular leg veins on the lateral aspect of the thigh (C(1A) or (S) E(P) A(S) P(N1) ) were randomized to receive pure CG or CG mixed with one-third lidocaine-epinephrine 1% (CGX) treatment. Lower limb photographs were taken before and after treatment and analyzed by blinded expert reviewers for efficacy assessment (visual vein disappearance). Patients' pain and satisfaction were assessed using visual analogue scales. RESULTS: Data from 102 of 110 randomized patients could be evaluated. Patient pain scores were significantly higher when pure CG was used than with CGX (p<.001). Patient satisfaction with treatment outcome was similar in the two groups. Objective visual assessment of vessel disappearance revealed no significant difference between the two agents (p=.07). CONCLUSION: Addition of lidocaine-epinephrine 1% to CG, in a ratio of one-third, significantly reduces sclerotherapy pain without affecting efficacy when treating telangiectasias and reticular leg veins.
