Regional anesthesia is an integral component of successful orthopedic surgery. Neuraxial anesthesia is commonly used for surgical anesthesia while peripheral nerve blocks are often used for postoperative analgesia. Patient evaluation for regional anesthesia should include neurological, pulmonary, cardiovascular, and hematological assessments. Neuraxial blocks include spinal, epidural, and combined spinal epidural. Upper extremity peripheral nerve blocks include interscalene, supraclavicular, infraclavicular, and axillary. Lower extremity peripheral nerve blocks include femoral nerve block, saphenous nerve block, sciatic nerve block, iPACK block, ankle block and lumbar plexus block. The choice of regional anesthesia is a unanimous decision made by the surgeon, the anesthesiologist, and the patient based on a risk-benefit assessment. The choice of the regional block depends on patient cooperation, patient positing, operative structures, operative manipulation, tourniquet use and the impact of post-operative motor blockade on initiation of physical therapy. Regional anesthesia is safe but has an inherent risk of failure and a relatively low incidence of complications such as local anesthetic systemic toxicity (LAST), nerve injury, falls, hematoma, infection and allergic reactions. Ultrasound should be used for regional anesthesia procedures to improve the efficacy and minimize complications. LAST treatment guidelines and rescue medications (intralipid) should be readily available during the regional anesthesia administration.

BACKGROUND: The saphenous nerve has great importance on the sensitivity of the lower limb. In its normal course, it enters the adductor canal and travels under the sartorius muscle, on the medial side of the thigh.
METHODS: The anatomical variation was found accidentally during routine cadaveric dissection of the thigh at the Human Anatomy Laboratory of the Department of Morphophysiology of the Faculty of Medical Sciences of Minas Gerais (FCMMG).
RESULTS: A different pattern of path of the saphenous nerve was found, which appears to perforate the sartorius muscle.
CONCLUSIONS: Complaints of pain in the lower limbs are highly prevalent in the adult population. Saphenous neuropathy is a pathological entity that is associated with such a clinic and may have compression or trauma as its etiology. In the context of compression, it can be caused due to the unusual nerve path, as described in the present study. In trauma, knowledge of this variation is important to prevent iatrogenic damage to nervous tissue during surgical procedures.
CONCLUSIONS: The anatomic variation presented may be related to the symptom of pain in the lower limbs and is also relevant in the surgical context, in order to prevent complications.

The aim of this study was to compare viscoelastic test results from samples collected from a jugular vein using a 20 G needle and a medial saphenous vein using a 22 G needle in cats presenting for elective ovariohysterectomy (OHE) or castration.
Forty apparently healthy cats (20 males and 20 females) presenting for elective OHE or castration were included in a prospective study observing viscoelastic test results from central and peripherally collected whole blood. Cats were anesthetized during blood collection with a standardized protocol including buprenorphine, ketamine, dexmedetomidine and isoflurane. Blood samples from jugular and saphenous veins were collected near simultaneously. Viscoelastic evaluations of whole blood were performed using a point-of-care device measuring clot time (CT), clot formation time (CFT), alpha angle (α), maximum clot formation (MCF), and amplitude at 10 and 20 mins (A10 and A20, respectively). Viscoelastometry continued post-clot time to determine a lysis index at 30 and 45 mins (LI30 and LI45, respectively) to assess fibrinolysis.
Studied cats had a median age of 18 months (range 5 months to 5 years) and a median weight of 3.6 kg (range 2.7-5.9 kg). A total of 80 samples were available for analysis. While lysis indices were not different, viscoelastic measures of coagulation differed between sampling sites (CT, P <0.005; CFT, P = 0.01; α, P <0.05; MCF, P <0.0005; A10, P <0.0005; A20, P <0.0005).
Viscoelastic results from jugular venous blood samples appear to be more hypercoagulable than those collected from the medial saphenous vein, suggesting that the same site should be used consistently for serial monitoring or for collecting study data.

Background/purpose: Plantar foot pain of neural origin is a challenging diagnosis to identify and treat. The purpose of this paper is to illustrate the novel way in which cupping was utilized in conjunction with neural glides to better diagnose and manage a patient who presented with symptoms of peripheral neuropathic plantar foot pain. Case description: A 65-year-old male presented to physical therapy with the diagnosis of plantar fasciitis by an orthopedic surgeon. The presentation included a diffuse area of pain toward the medial border of the foot with a peripheral neuropathic pain description. Cupping was used to identify pain in the saphenous nerve distribution and aided in resolving symptoms with the concomitant use of lower quarter neural glides. Outcome: At discharge and 1-year follow-up, the patient had a full resolution of symptoms and a return to prior level of function. Self-report outcomes included the numeric pain rating scale and the lower extremity functional scale. Discussion: This case is the first to describe the use of cupping combined with neural glides in the diagnosis and management of peripheral neuropathic pain from the saphenous nerve that was previously diagnosed as plantar fasciitis. The proposed mechanisms behind this treatment are also reviewed. Conclusion: In patients that present with symptoms of plantar fasciitis, testing neural glides combined with cupping may be warranted to confirm or refute the presence of a peripheral neuropathic pain source. Further studies are necessary to determine the mechanisms and further utility of the combined interventions in well controlled trials. Level of Evidence: Level IV.

BACKGROUND: The treatment of incompetent truncal veins has been innovated by the introduction of minimally invasive non-thermal non-tumescent (NTNT) techniques. One of these consists of the use of cyanoacrylate glue to occlude the vein lumen by means of the VenaSeal device. Areas covered: This expert-review aims to evaluate NTNT ablation of incompetent saphenous trunks using the VenaSeal device. Expert commentary: Cyanoacrylate adhesive embolization of incompetent truncal veins using the VenaSeal device is a safe and efficacious innovative technique. Further studies are needed to evaluate anatomical and clinical outcomes at long term.

OBJECTIVE: The aim of this study is to present our 7-year results of external valvuloplasty for isolated great saphenous vein (GSV) insufficiency.
METHODS: External valvuloplasty was applied in 83 patients with isolated GSV insufficiency. Follow-up consisted of venous color duplex scanning performed on the first postoperative day, the first postoperative month, and then annually. Valvular insufficiency, venous reflux, and venous thrombosis formation in the saphenofemoral junction were the main outcomes.
RESULTS: A complete clinical and radiological healing was observed in 50 patients (60%). In 13 cases (15.6%), a secondary surgical treatment was performed consisting of vena saphena magna high ligation/stripping and varicose vein excisions, mainly due to severe and progressive vena saphena magna valvular insufficiency and clinical persistence of symptoms. Eight patients (9.6%) developed superficial vein thrombosis, and only one patient (1.2%) developed deep vein thrombosis. Contact was lost from 32 patients (38.5%) for different reasons.
CONCLUSIONS: External valvuloplasty is an effective surgical technique for selected cases of isolated GSV insufficiency without extensive varicose dilatations. This alternative method can be safely administered as an alternative to high ligation and conventional GSV stripping.
