Tumor Cerebellopontine angle (CPA) merupakan tumor fossa posterior terbanyak dan merupakan 5-10% dari tumor intrakranial. Penatalaksanaan anestesi pada kasus tumor CPA sangat menantang, dan memerlukan perhatian khusus terhadap disfungsi batang otak, posisi pasien, pemantauan neurofisiologi intraoperatif, dan adanya risiko venous air embolism (VAE). Pasien wanita, 16 tahun, 45 kg, suspek CPA tipe schwannoma akustik dengan keluhan sakit kepala selama 2 bulan. Tidak ada riwayat tinitus dan gangguan keseimbangan. CT-scan kepala memperlihatkan massa padat dengan bagian kistik di cerebellopontine angle kanan. Prosedur pembedahan dilakukan dalam posisi prone dan memanjang hingga 13 jam. Rumatan anestesi ditujukan untuk stabilisasi hemodinamik dan pencegahan hipotermia dengan penghangat blower dan infus hangat. Perdarahan selama pembedahan sekitar 1800 ml. Pasien diekstubasi setelah 3 hari di ICU. Prosedur bedah untuk tumor CPA memiliki risiko tinggi dan membutuhkan waktu lama, sehingga meningkatkan mortalitas dan morbiditas akibat risiko hipotermia dan ketidakstabilan hemodinamik yang lebih tinggi. Pada kasus ini dengan keterbatasan alat monitoring, dilakukan observasi ketat untuk kejadian VAE dan pencegahan komplikasi pascabedah dengan menjaga hemodinamik tetap stabil dengan pemberian cairan adekuat dan pencegahan hipotermia dengan penggunaan blower warmer dan infus hangat. Pada kasus ini, lama pembedahan selama 13 jam diantisipasi dengan monitoring yang ketat, pemberian volume adekuat dan pencegahan hipotermi. Prolonged Operation in Patient with Cerebellopontine Angle (CPA) TumorAbstractCerebellopontine angle (CPA) tumor is the most common neoplasms in the posterior fossa, accounting for 5-10% of intracranial tumors. Anesthetic management is very challenging and needs special attention due to brain dysfunction, patient position, neurophysiological monitoring intraoperative, and the risk of venous air embolism (VAE). Female patient, 16 years old, 45 kg, with a suspected CPA acoustic schwannoma presented headache for 2 months. No history of tinnitus and balance disorders. Head CT-scan showed solid mass with cystic sections at right cerebellopontine angle. During procedure patient was in prone position and the operation took 13 hours long. Maintenance anesthesia aims to stabilize hemodynamic with adequate fluid replacement and prevention hypothermia with blower warmer and fluid warmer. Blood loss during the operation about 1800 ml. The patient was extubated after 3 days in the ICU. Surgical procedure in cerebellopontine angle surgery has a high risk and requires a long time. Prolonged duration of surgery will increases mortality and morbidity, because of the higher risk of hypothermia and hemodynamic instability. With limited monitoring equipment, we stabilize hemodynamic and to prevent the risk of VAE by adequate volume replacement. Hypothermia prevention by blower and fluid warmer. In this case, 13 hours long the operation makes us should maintenance hemodynamic by given adequate volume replacement and prevention of hypothermia.

Pneumocephalus due to cerebral venous air embolism is an uncommon phenomenon. It results from retrograde progression of low weight air bubbles into dural venous sinuses during manipulation of a venous catheter, more frequently a central venous catheter through the subclavian and the jugular veins. However, it may also occur in relation with a peripheral intravenous catheter as in our case. We report a 91 year old female patient with congestive heart failure who had been examined in our emergency department two days previously due to dyspnea and received diuretic treatment through a peripheral intravenous line. She presented with vomiting and headache without obvious neurological deficits. Non-contrast cranial CT scan revealed wide spread punctate air bubbles inside and outside the cranial vault (pneumocephalus), within the venous system. The pneumocephalus was considered as iatrogenic due to the previous peripheral venous catheterization that resulted in retrograde migration of air bubbles through various venous connections into dural venous sinuses and extracranial veins. Since cerebral venous air embolism is a potentially serious complication of various medical procedures, it should be considered in differential diagnosis of nontraumatic headache and vomiting especially when there is a recent manipulation of venous lines. Cranial CT scan is helpful for early diagnosis.

The posterior fossa houses essential brainstem nuclei, cranial nerves, cerebral vasculature, and mechanisms for cerebrospinal fluid drainage. Anesthetic considerations for posterior fossa surgery include thorough preoperative evaluation, intraoperative monitoring, and anesthetic planning to allow neurophysiological monitoring. Careful positioning is imperative to optimize surgical conditions and to risk stratify patients for complications, including venous air embolus. Venous air embolus is a common complication of posterior fossa surgery given the plentitude of venous channels in the posterior fossa, and rapid recognition is key to managing this complication.  Posterior fossa surgery also has a number of other known complications including postoperative apnea, prolonged ventilation, and possible brainstem stroke.  This review contains 4 tables, 1 video, and 31 references.

Local anesthesia is a safe and less invasive anesthetic management for the endovascular approach to elective aortic aneurysm. We have successfully extended the indication of local anesthesia to a high-risk patient with leaking aneurysm and stable hemodynamics. Patient and methods: A 86 year old patient with renal insufficiency due to longstanding hypertension, coronary artery and chronic obstructive lung disease was transferred to our hospital with a leaking abdominal aortic aneurysm. Stable hemodynamics allowed to perform a fast CT scan, that confirmed the feasibility of endovascular repair. A bifurcated endograft (24mm x 12mm x 153mm) was implanted under local anesthesia. Results: The procedure was completed within 85 minutes without problems. The complete sealing of the aneurysm was confirmed by CT scan on the third postoperative day. Twenty months later, the patient is doing well and radiological control confirmed complete exclusion of the aneurysm. Discussion: The endoluminal treatment is a minimally invasive technique. It's feasibility can be rapidly assessed by CT scan. The transfemoral implantation can be performed under local anesthesia provided that hemodynamics are stable. This anesthetic management seems to be particularly advantageous for leaking abdominal aortic aneurysm since it doesn't change the hemodynamic situation in contrast to general anesthesia. Hemodynamic instability, abdominal distension or tenderness may indicate intraperitoneal rupture and conversion to open graft repair should be performed without delay.
