Spinal correction in patients with Fukuyama congenital muscular dystrophy.

BACKGROUND: Fukuyama congenital muscular dystrophy (FCMD) is one of the most common congenital progressive muscular dystrophies in Japan. Some patients develop a severe spinal deformity that leads to an unstable sitting position or pain. Since 2008, we have treated FCMD using posterior spinal fusion. This study reports the short-term clinical and radiographic results of posterior spinal correction and fusion in FCMD. METHODS: We retrospectively reviewed 11 consecutive FCMD patients, average age 13 years old, treated with posterior spinal instrumentation and fusion between 2008 and 2015. All patients were non-ambulatory and complained about difficulty sitting and/or buttock pain. Posterior spinal correction was performed to halt progression of spinal deformity and improve their sitting balance. Assessment was performed clinically and with radiological measurements at a mean follow up period of 34.5 months. To evaluate functional status of patients after surgery objectively, a Muscular Dystrophy Spine Questionnaire (MDSQ) was obtained at the final follow up. RESULTS: The mean height, weight and body mass index of the patients were 144.1 ± 11.8 cm, 26.5 ± 8.7 kg and 12.5 ± 2.6 kg/m2. The average intensive care unit stay was 1.3 days. Five patients had complications related to surgery. The mean preoperative major Cobb angle and pelvic obliquity (PO) were 65.5 ± 41.7° and 31.4 ± 28.9°, respectively, were corrected to 34.4 ± 29.7° and 20.0 ± 18.7° just after the surgery, and were maintained at 35.1 ± 29.9° and 20.5 ± 21.1° at the final follow up. The average MDSQ score was 35.8 ± 13.2 at the final follow up. CONCLUSION: Posterior spinal correction and fusion in FCMD achieved good radiographic results and clinical improvement with acceptable perioperative complications. FCMD patients are mentally impaired and physically small, so post-operative observation and close attention to perioperative complications are critical.

Spinal fusion in a patient with Fukuyama congenital muscular dystrophy.

Many studies have evaluated surgical treatments for spinal deformities in patients with neuromuscular disease. However, few reports have described patients with Fukuyama congenital muscular dystrophy (FCMD). A 13-year-old boy with FCMD was unable to sit for long periods or sleep in the supine position because of progressive scoliosis. His Cobb angle worsened from 27° to 41° in 5months. He underwent standard posterior spinal fusion and pedicle-screw-alone fixation from T5 to S1. Postoperatively, his Cobb angle improved from 41° to 25° without exacerbation for 2years. After the surgery, he was able to sit for longer periods without pain, and he and his family were satisfied with the efficacy of the spinal fusion. Some patients with mild FCMD can sit at the age of puberty, but progression to scoliosis is possible. Therefore, spinal fusion for progressive scoliosis in patients with FCMD should be considered.

[Total intravenous anesthesia for a patient with Fukuyama congenital muscular dystrophy undergoing scoliosis surgery].

We described the anesthetic management of a 17-year-old male patient with Fukuyama congenital muscle dystrophy (FCMD) who underwent surgical repair for scoliosis under total intravenous anesthesia. The patient had severe constructive lung disease (%VC 18.6%). Left ventricular wall motion was reduced (left ventricular ejection fraction 40%). Propofol and remifentanil were continuously infused to maintain anesthesia, but we did not use any muscle relaxant throughout the course. We used arterial pressure-based cardiac output and stroke volume variation as a guide for circulatory management. We could not find any congestion on chest X-ray after the surgery. The emergence and recovery from the anesthesia was rapid and muscle strength was enough, and we could extubate the patient just after the end of the surgery. No respiratory and cardiac complications occurred during the postoperative period. Even though he was in the young age in FCMD, respiratory and cardiac complications were severely impaired. For successful anesthetic management in FCMD patient, we should take care of rapid emergence from anesthesia and also we should not impair muscle strength for good postoperative respiratory function. Appropriate hemodynamic monitoring to avoid postoperative cardiac congestion is also required.

Anesthesia for a child with Walker-Warburg syndrome.

BACKGROUND AND OBJECTIVES: Walker-Warburg Syndrome is a rare, autosomal recessive congenital muscular dystrophy manifested by central nervous system, eye malformations and possible multisystem involvement. The diagnosis is established by the presence of four criteria: congenital muscular dystrophy, type II lissencephaly, cerebellar malformation, and retinal malformation. Most of the syndromic children die in the first three years of life because of respiratory failure, pneumonia, seizures, hyperthermia and ventricular fibrillation. CASE REPORT: The anesthetic management of a two-months-old male child listed for elective ventriculo-peritoneal shunt operation was discussed. CONCLUSIONS: A careful anesthetic management is necessary due to the multisystem involvement. We reported anesthetic management of a two-months-old male child with Walker-Warburg Syndrome who was listed for elective ventriculo-peritoneal shunt operation.

Justificativa e objetivos: A síndrome de Walker-Warburg é uma distrofia muscular autossômica recessiva congênita rara, manifestada pelo sistema nervoso central com malformações oculares e possível envolvimento de vários sistemas. O diagnóstico é estabelecido pela presença de quatro critérios: distrofia muscular congênita, lisencefalia tipo II, malformação cerebelar e malformação da retina. A maioria das crianças com a síndrome morre nos primeiros três anos de vida por causa de insuficiência respiratória, pneumonia, convulsões, hipertermia e fibrilação ventricular. Relato de caso: É discutida a conduta anestésica em uma criança do sexo masculino, de dois meses, programada para cirurgia eletiva de derivação ventrículo-peritoneal. Conclusões: Uma abordagem anestésica cuidadosa é necessária por causa do envolvimento de vários sistemas. Relatamos a conduta anestésica em uma criança do sexo masculino de dois meses com síndrome de Walker-Warburg, que foi programada para cirurgia eletiva de derivação ventrículo-peritoneal. .

Left ventriculoplasty for dilated cardiomyopathy in Fukuyama-type muscular dystrophy.

A 29-year-old man was hospitalized because of heart failure causing dilated cardiomyopathy (DCM). On admission, he had elevated creatinine kinase levels (hyper CKemia) (4283IUl⁻) and false enlargement of bilateral calves. By a muscular biopsy, he was diagnosed as Fukuyama-type muscular dystrophy. Although neuromuscular diseases are often related to cardiomyopathy, reports showing a relation between cardiomyopathy and Fukuyama-type muscular dystrophy have been rare. Our group performed the partial left venticulectomy of the posterior wall and approximation of the papillary muscle, mitral valve annuloplasty, and tricuspid valve annuloplasty for DCM in the patient with Fukuyama-type muscular dystrophy, after obtaining informed consent from the patient and his family. At the 1-year follow-up examination, the neuromuscular symptoms had not progressed, and the left ventricular function was improved (left ventricular end-diastolic dimension (LVDd) 77-66 mm, left ventricular end-systolic dimension (LVDs) 73-59 mm, and ejection fraction (EF) 26-30%). This is the first case report of a left ventriculoplasty in a patient with Fukuyama-type muscular dystrophy.
