Dentre os fatores que podem desencadear a compressão do canal de Guyon inclui-se o aneurisma da artéria ulnar. Uma das abordagens cirúrgicas é a reconstrução microcirúrgica através da ressecção e arteriorrafia término-terminal ou enxerto venoso de interposição. O objetivo deste trabalho é relatar o caso de paciente que desenvolveu neuropatia do nervo ulnar secundária à presença de aneurisma da artéria ulnar no canal de Guyon. Foi realizada a descompressão cirúrgica através de uma abertura do canal e a ressecção do segmento lesionado. A artéria ulnar foi reconstruída através da anastomose término-terminal microcirúrgica. O resultado foi o alívio completo dos sintomas no pós-operatório com manutenção do fluxo vascular. Descritores: Nervo Ulnar; Neuropatia Radial; Ferimentos e Lesões; Aneurisma. Referências Guyon F.

Canal Syndrome

Guyon's canal syndrome, an ulnar nerve entrapment at the wrist, is a well-recognized entity. The most common causes that involve the ulnar nerve at the wrist are compression from a ganglion, occupational traumatic neuritis, a musculotendinous arch and disease of the ulnar artery. We describe two cases of Guyon's canal syndrome and discuss the anatomy, aetiology, clinical features, anatomical classification, diagnostic criteria and treatment. It is emphasized that the knowledge of both the surgical technique and anatomy is very important for a satisfactory surgical result.

Canal Syndrome

In certain occupations, injuries and microtrauma are commonly encountered by the soft tissues of the hand in the adult population, which may, however, less frequently lead to arterial occlusion. One such example is that of the Hypothenar Hammer Syndrome (HHS). It is a rare traumatic disease of the hand, caused by blunt traumas to the heel of the hand that may damage the ulnar artery at the level of hypothenar eminence. This results in occlusion or aneurysm of the vessel. It is of clinical importance due to the risk of loss of limb function following digital ischemia. The ulnar nerve barely gets compressed in the Guyon’s canal, which may in turn cause Guyon’s canal syndrome. This is a case of a 43-year-old male patient who presented with painful swelling of the right hand, which was diagnosed as a bizarre presentation of a bilobed and partially thrombosed pseudoaneurysm of the ulnar artery producing Guyon’s canal syndrome that had to be surgically excised. The objective of this case is to highlight the clinical presentation of HHS for early diagnosis and treatment.

Anomalous Branch

We present a case of isolated Abductor Digiti Minimi (ADM) palsy caused by an anomalous branch from the ulnar artery. Electrophysiology suggested selective involvement of the motor branch to the ADM in the Guyon's canal. Surgical exploration revealed an anomalous branch of the ulnar artery causing a pincer effect on the nerve to the ADM. Division and ligation of this branch effectively decompressed the nerve and the patient recovered satisfactorily. This report highlights the need to consider vascular aberrations as a differential diagnosis for ulnar neuropathy in Guyon's canal.
