Spinal progressive muscular atrophy (SPMA) is a rare lower motor neuron disease in which anesthetic management is often difficult as a result of muscle weakness and hypersensitivity to neuromuscular blocking agents. A 43-year-old female patient with SPMA was scheduled to undergo laparotomy for ovarian teratoma. Her vital capacity was only 530 ml and % volume capacity was 22.2%, indicating a severe restrictive pulmonary disfunction. ⋯ Postoperative pain control was stable using continuous epidural infusion of 0.2% ropivacaine without neurological adverse effects. One day after surgery, the trachea was extubated and respiratory function did not aggravate. Despite the controversy surrounding the use of neuraxial blocks in motor neuron diseases, in this case, epidural anesthesia was useful to keep the respiratory function stable.

Case Reports
[Anesthetic management of a patient with Klippel-Trenaunay syndrome undergoing caesarean section].
Klippel-Trenaunay syndrome (KTS) is characterized by capillary and venous malformation and hypertrophy of bone and soft tissues. A 29-year-old primigravida, who had been diagnosed of KTS by her hemangiomas and varicosities in the right leg, pubic area, rectum, vagina and lower abdominal area, was scheduled to receive caesarean section at 37 weeks gestation because vaginal delivery might cause hemorrhagic complications and extension of the venous lesions. ⋯ There were no complications such as massive hemorrhage, disseminated intravascular coagulation and deep venous thrombosis in the perioperative period. Careful anesthetic considerations for the prevention of hemorrhagic and thrombotic complications are necessary for cesarean section in a patient with KTS.

Here, we report a case of an unexpectedly complicated laryngoscopy caused by massive mandibular tori. A 64-year-old man with mitral regurgitation and aortic regurgitation was scheduled for a double valve replacement. Thyromental distance and the Mallampati score were used as predictive factors of difficult intubation, and both factors were within the normal range. ⋯ Intubation with a 7.5 mm tube was successful at the third attempt. We hope our experience will serve as a reminder to clinicians that mandibular tori, although benign and without subjective symptoms, could have significant effects upon direct laryngoscopy by compromising the line of vision. Preoperative oral evaluation is critical and aggressive treatment should be considered.

Anesthesia for the tracheobronchial stent placement involves the risk of airway narrowing and obstruction. Controlled ventilation with relatively high airway pressure is usually used to maintain oxygenation and ventilation during anesthesia. However, controlled ventilation does not always provide tidal volume and oxygenation due to gas leakage from tracheobronchial fistula. ⋯ Anesthesia was induced with remifentanil and sevoflurane with spontaneous respiration. When inserting the rigid bronchoscope, cough reflex occurred and propofol was added to deepen the anesthesia. The stent placement was performed with general anesthesia under spontaneous respiration without any complications.

Case Reports
[Case of abdominal compartment syndrome (ACS) associated with perforating appendicitis].
A 4-year-old girl with perforating appendicitis developed abdominal compartment syndrome (ACS). Appendicitis in children of preschool age is highly likely to rupture, resulting in serious condition. ⋯ ACS causes progressive multiple organ failure through compromising the respiratory and circulatory systems and injuring multiple organs, leading to generalized inflammatory reactions. We should, therefore, manage ACS patients systemically sharing a notion that they must be treated early with abdominal decompression by laparotomy.
