Neuralgia del nervio safeno interno en pacientes operados de várices esenciales en miembros inferiores / Neuralgia of the Internal Saphenous Nerve in Patients Operated on for Essential Varicose Veins of the Lower Limbs

Introducción: La neuralgia del nervio safeno interno, possafenectomía, constituye la expresión natural de una lesión nerviosa de tipo troncular periférico y constituye un síndrome clínico frecuente pero poco estudiado desde todos los puntos de vista. Objetivo: Valorar la neuralgia del safeno interno en los pacientes operados de várices esenciales en miembros inferiores. Método: Se realizó un estudio descriptivo- retrospectivo en 60 pacientes operados (stripping o flebo-extracción) en el servicio de Angiología y Cirugía Vascular del Hospital Docente Clinicoquirúrgico "General Freyre de Andrade" con el diagnóstico de várices esenciales en los miembros inferiores y presencia de neuralgia del nervio safeno interno. El estudio se realizó de enero a diciembre de 2017. Las variables estudiadas fueron: sexo, localización de la safenectomía (izquierda, derecha, bilateral), presencia de neuralgia en el nervio safeno interno. Se trabajó con valores de frecuencias absolutas y relativas. Resultados: 40 por ciento de las safenectomías fueron bilaterales; 31,6 por ciento en miembro inferior derecho y 28,3 por ciento en el miembro inferior izquierdo. El 80 por ciento eran mujeres (25 por ciento lado izquierdo, 25 por ciento lado derecho y 50 por ciento bilateral) y el 20 por ciento hombres (58,3 por ciento lado derecho y 41,7 por ciento lado izquierdo). Pacientes con neuralgia del safeno interno 23,3 por ciento (41,7 por ciento hombres y 18,8 por ciento mujeres). Conclusión: El reconocimiento adecuado de la neuralgia del safeno interno permite excluir otras complicaciones de tipo vascular y establecer medidas profilácticas para evitarla(AU)

Introduction: Post-saphenectomy neuralgia of the internal saphenous nerve is the natural expression of a peripheral truncal nerve injury and constitutes a frequent clinical syndrome; however, it is rarely studied, from all points of view. Objective: To assess neuralgia of the internal saphenous nerve in patients operated on for essential varicose veins of the lower limbs. Method: A descriptive-retrospective study was carried out in 60 surgically intervened patients (stripping or phlebo-extraction) in the angiology and vascular surgery service of Freyre de Andrade Clinical-Surgical Teaching Hospital for a diagnosis of essential varicose veins of the lower limbs and manifestation of neuralgia of the internal saphenous nerve. The study was carried out from January to December 2017. The variables studied were sex, location of the saphenectomy (left, right, or bilateral), and manifestation of neuralgia in the internal saphenous nerve. We worked with absolute and relative frequency values. Results: 40 percent of the saphenectomies were bilateral, 31.6 percent were performed in the lower right limb, and 28.3percent corresponded to the lower left limb. 80 percent were women (left side: 25 percent, right side: 25 percent, and bilateral: 50 percent) and 20 percent were men (right side: 58.3 percent, and left side: 41.7 percent). Patients with neuralgia of the internal saphenous never accounted for 23.3 percent (41.7 percent were men and 18.8 percent were women). Conclusion: The correct identification of neuralgia of the internal saphenous nerve allows to exclude other vascular complications and to establish prophylactic measures to avoid it(AU)

Effectiveness of Low-Intensity Laser Therapy on Tissue Repair Following Saphenectomy in Patients Who Underwent Coronary Artery Bypass Graft: A Randomized, Double-Blind Study.

OBJECTIVE: To verify the effectiveness of low-intensity laser therapy (LLLT) on tissue repair following saphenectomy during postoperative period in patients having undergone coronary artery bypass graft (CABG). MATERIALS AND METHODS: A randomized clinical trial, controlled and double-blind study was conducted with 40 volunteers, divided into 2 groups: a placebo group (PG, n = 20) and a laser group (LG, n = 20). The patients in the LG group were irradiated with laser during saphenectomy (InGaAlP, λ 660 nm, energy density 6 J/cm2) daily from the first to the fourth postoperative day. The surgical incision was clinically evaluated and imaged at the beginning and at the end of the treatment. The areas of hematoma and hyperemia were evaluated using the software ImageJ 1.4©, and border closure was evaluated by three researchers, who were blinded concerning the allocation of the participants. RESULTS: The LG group presented a reduction of the areas of hematoma and hyperemia (p = 0.0003) and better border closure (p = 0.009), when compared with the PG group. CONCLUSIONS: The proposed LLLT protocol improved the tissue repair following saphenectomy in CABG patients.

Low-intensity LED therapy (λ 640 ± 20 nm) on saphenectomy healing in patients who underwent coronary artery bypass graft: a randomized, double-blind study.

Myocardial revascularization surgery (CABG) is the most appropriate treatment for coronary artery disease. Currently, the great challenge is to reduce postoperative complications, such as wound infections, dehiscence, pain, and patients' quality of life. The saphenectomy is the target of complications in 10% of cases, which can cause greater morbidity, time, and cost of hospitalization. Studies show that low-intensity laser or light-emitted diode (LED) therapy promotes positive biomodulation of the tissue repair process, culminating in a lower incidence of dehiscence, pain reduction, and improvement in quality of life. The objective of the present study was to evaluate clinically the saphenous tissue repair after LED therapy. Forty subjects of both genders who underwent CABG with extracorporeal circulation were randomly divided into two groups: the placebo (PG) and experimental (EG). The experimental group underwent low-intensity LED therapy (λ 640 ± 20 nm, 6 J/cm2) on saphenectomy. The tissue repair was analyzed by digital photogrammetry on the first and fifth postoperative day. The border closure was blindly evaluated by three researchers. The hematoma and hyperemia area was quantitatively analyzed using ImageJ© software. The results showed that in the experimental group, there were less bleeding points and no dehiscence in saphenectomy, as compared to the placebo group. There was also a smaller area of hematoma and hyperemia in the experimental group (p < 0.0009). These data lead to the conclusion that the type of phototherapy protocol employed can assist in tissue repair.

Radiofrequency thermal ablation versus conventional saphenectomy / Ablação térmica por radiofrequência versus safenectomia convencional

Varicose veins of the lower limbs have a high prevalence worldwide. New treatment techniques have been developed with the objectives of improving patients' quality of life and reducing recovery times. OBJECTIVE: To evaluate patients with incompetent saphenous veins treated using conventional saphenectomy or radiofrequency ablation (RF), in terms of postoperative status. METHODS: From May 2012 to April 2013 146 varicose veins patients with saphenous insufficiency, 90 of whom were treated with conventional surgery (G1) and 56 with RF ablation (G2), were evaluated prospectively. RESULTS: In G1, 88.61% of patients complained of postoperative pain and needed to take analgesics, compared with 28.85% in G2 (p<0.05). Mean pain rating on an analog scale from 0 to 10 was 3.91±2.13 points for G1 and 1.76±3.01 points for G2 (p<0.05). Recovery periods ranged from 26.63±13.3 days to 18.26±19.37 days, for G1 and G2 respectively. Mean time taken to become totally asymptomatic was 66.78±60.9 days for G1 and 38.38±46.8 days for G2 (p<0.05). CONCLUSIONS: The RF treatment method caused less postoperative pain and resulted in earlier recovery, when compared to conventional saphenectomy...

Textiloma inguinal después de safenectomía simulador de neoplasia / Groin textiloma after saphenectomy: resemblance to neoplasm

Introducción: Los textilomas pueden confundirse con neoplasias malignas y ocurrir en ubicaciones inverosímiles. Caso clínico: Mujer de 73 años de edad, quien acudió por un tumor en la ingle derecha de tres años de evolución, que apareció después de safenectomía bilateral. A la exploración física: ingle derecha con tumor oval de 8 cm, de consistencia renitente, abajo del ligamento inguinal y sobre los vasos femorales. Un ultrasonido y una tomografía computarizada evidenciaron un tumor quístico mixto. A la exploración quirúrgica: tumor de 8 cm adherido a la vena femoral; se llevó a cabo reseccción en bloque. El examen histopatológico indicó textiloma. La evolución posoperatoria fue satisfactoria. Conclusiones: El textiloma es capaz de simular una neoplasia; su ubicación en la ingle es excepcional.

BACKGROUND: Textilomas may mimic a malignant neoplasm and may occur in rare locations. CLINICAL CASE: A 73-year-old female presented a groin tumor of 3 years duration after saphenectomy. Physical exam of the right groin area demonstrated an 8-cm oval tumor below the inguinal ligament and above the femoral vessels. An ultrasound and a CT scan showed a mixed cyst. During surgical exploration of the groin, an 8-cm tumor fixed to the femoral vein was extirpated en bloc. Histopathological results reported a textiloma. The patient had an uneventful postoperative evolution. CONCLUSIONS: Textilomas may mimic a neoplasm, but their occurrence in the groin is exceptional.
