Acute Carpal Tunnel Syndrome due to Persistent Median Artery thrombosis: Case report / Síndrome do túnel do carpo aguda por trombose da artéria mediana: Relato de caso

Abstract Carpal tunnel syndrome is the most common compressive neuropathy of the upper limb, affecting ~ 4% of the general population. The clinical picture is characterized by pain and, mainly, paresthesia in the median nerve territory, of insidious onset and, in the most severe cases, loss of strength and atrophy of the thenar musculature is observed. It is an extremely common pathology in the daily practice of hand surgery, and in most cases, it can be treated with conservative methods. We present here an atypical case of carpal tunnel syndrome, of acute onset, triggered by persistent median artery (PMA) thrombosis, condition associated with distal embolization and hypoper-fusion of the limb.

Resumo A síndrome do túnel do carpo é a neuropatia compressiva mais comum do membro superior, afetando ~ 4% da população geral. O quadro clínico caracteriza-se por dor e, principalmente, parestesia no território do nervo mediano, de início insidioso e, nos casos mais graves, observa-se perda de força e atrofia da musculatura tenar. Trata-se de patologia extremamente comum na prática diária de cirurgia da mão, e na maior parte dos casos pode ser tratada com métodos conservadores. Apresentamos aqui um caso atípico de síndrome do túnel do carpo, de surgimento agudo, desencadeado pela trombose da artéria mediana persistente, quadro associado com embolização distal e hipoperfusão do membro.

WALANT versus intravenous regional anesthesia for carpal tunnel syndrome: a randomized clinical trial

ABSTRACT BACKGROUND: There are several anesthetic techniques for surgical treatment of carpal tunnel syndrome (CTS). Results from this surgery using the "wide awake local anesthesia no tourniquet" (WALANT) technique have been described. However, there is no conclusive evidence regarding the effectiveness of the WALANT technique, compared with the usual techniques. OBJECTIVE: To evaluate the effectiveness of the WALANT technique, compared with intravenous regional anesthesia (IVRA; Bier's block), for surgical treatment of CTS. DESIGN AND SETTING: Randomized clinical trial, conducted at Hospital Alvorada Moema and the Discipline of Hand Surgery, Universidade Federal de São Paulo (UNIFESP), São Paulo (SP), Brazil. METHODS: Seventy-eight patients were included. The primary outcome was measurement of perioperative pain through a visual analogue scale (VAS). The secondary outcomes were the Boston Questionnaire score, Hospital Anxiety and Depression Scale (HADS) score, need for use of analgesics, operating room times, remission of paresthesia, failures and complications. RESULTS: The WALANT technique (n = 40) proved to be superior to IVRA (n = 38), especially for controlling intraoperative pain (0.11 versus 3.7 cm; P < 0.001) and postoperative pain (0.6 versus 3.9 cm; P < 0.001). Patients spent more time in the operating room in the IVRA group (59.5 versus 46 minutes; P < 0.01) and needed to use more analgesics (10.8 versus 5.7 dipyrone tablets; P = 0.02). Five IVRA procedures failed (5 versus 0; P = 0.06). CONCLUSIONS: The WALANT technique is more effective than IVRA for CTS surgery.

Síndrome de arteria mesenterica superior: reporte de un caso y revisión de la literatura / Superior mesenteric artery syndrome: a case report and literature review

El Síndrome de la Arteria Mesentérica Superior, es una patología rara, en la cual la Arteria Mesentérica Superior comprime la tercera porción del duodeno, ocasionando obstrucción mecánica del mismo. Se describe el caso clínico de un paciente femenino de 44 años de edad con el diagnóstico de Síndrome de Arteria Mesentérica Superior (Síndrome de Wilkie) A quien se le realizó duodeno yeyuno anastomosis latero lateral por vía laparoscópica con resultados satisfactorios en el Serviciode Cirugía II del Hospital Universitario de Caracas.

Superior mesenteric artery compressive syndrome, Wilkie´s syndrome, is a rare pathology; in this, the superior mesenteric artery compress the third duodenal portion and cause obstruction. We report a case of a 44 years old woman with the diagnosis of superior mesenteric artery compressive syndrome who underwent laparoscopic latero-lateral duodeno - jejunostomy with satisfactory evolution in Servicio de Cirugía II from Hospital Universitario de Caracas.

Conduta atual nas síndromes compressivas do membro superior / Current approach to upper extremities entrapment neuropathies

As síndromes compressivas estão entre as causas mais comuns de queixas nos ambulatórios dos cirurgiões plásticos e ortopedistas. Os sintomas podem ser evidentes, mas muitas vezes passam despercebidos ao médico generalista. Facilmente são confundidos com sintomas vasculares, da “idade” ou somatização. O entendimento da fisiopatogenia destas lesões auxiliará no diagnóstico precoce e no tratamento mais adequado de cada caso. Neste artigo abordaremos de forma simplificada o manejo clínico, diagnóstico e a conduta nas principais síndromes compressivas do membro superior.

Compressive syndromes are among the most commons causes of complaint in the offices of plastic surgeons and orthopedists. Although the symptoms may be evident, they often go unnoticed to the primary-care physician. They are easily mistaken for vascular symptoms, “aging”, or somatization. An understanding of the physiopathogeny of such lesions will be helpful in the early diagnosis and to select the most appropriate treatment for each case. In this article we briefly address the clinical management, diagnosis, and the approach to the main compressive syndromes of the upper limbs.
