Complication belong to Stellate ganglion blockade after cervical trauma

Abstract

Aim: Stellate ganglion block (SGB) is one of the most often used sympathetic blockade procedure. Despite performed by experienced physicians some complications may occur.
Case: The right brachial plexus injury was diagnosed in the patient who admitted to orthopedia clinic, with weakness in the right arm, and pain after motor vehicle accident. There was no response to medical treatment of fortyfour-years-old female patient and there was loosing of sensation from dis the right elbow joint to fingers on the radial and median nerve tracing. In the electromyelography; C5-T1 root avulsion, and MRI; Patient was evaluated as CPRS I (Complex regional pain syndrome) phase 1. In spite of medical treatment, SGB was performed. Respiratory arrest occurred 4-5 minutes after injection. Patient was breated with mechanical ventilator during 2 hours, and discharged 24 hours later with normal vital functions. One year later, the patient admitted the algology polyclinic with strong pain in the same area. Stellate ganglion Radyofreguency (RF) was planned. The first RF cannula was placed under fluoroscopy. Cerebrospinal fluid was seen in the second canula, and canula was withdrawn. Third cannula was placed in another region, and conventional RF was performed through two canuls. For anatomical structure defect, we planned cervical MR myelography. In the cervical MR myelography, traumatic pseudomeningocele was observed at the level of C6-T1 on the brachial plexus. Intraspinal block was thought to develop during blockade of stellate ganglion due to this.
