Article Synopsis
- - Moyamoya disease (MMD) is a cerebrovascular condition marked by narrowing of the internal carotid artery (ICA), with some patients also experiencing stenosis in the external carotid artery (ECA), though this is uncommon.
- - A 48-year-old woman with no prior health issues presented with serious neurological symptoms and imaging revealed significant stenosis in both the ICA and ECA, leading to her diagnosis of MMD.
- - The treatment involved a combination of percutaneous transluminal angioplasty (PTA) with a kissing balloon technique, followed by direct and indirect revascularization, showing potential effectiveness despite ongoing debates on the best treatment sequence.
Article Synopsis
- A rare case of spontaneous direct vertebral artery-external vertebral venous plexus (VA-EVVP) fistula was diagnosed in an 82-year-old woman without trauma history or neurological deficits, presenting with right hemianopsia.
- Initial MRI suggested an old infarction and a dural arteriovenous fistula, but further imaging revealed a specific AV fistula at the C2 level.
- The patient underwent successful coil embolization, resulting in complete obliteration of the fistula after follow-up, providing new insights into treating VA-EVVP fistulas.
Article Synopsis
- Central giant cell granuloma (CGCG) is a rare, benign bone lesion primarily found in the jawbones, but this case highlights its occurrence in the temporal bone of a 31-year-old female.
- The patient underwent advanced imaging which revealed a mass with significant involvement of nearby structures, leading to preoperative embolization to minimize blood supply before surgical intervention.
- Post-surgery, a histopathological analysis confirmed the diagnosis of CGCG, and the patient had an uncomplicated recovery, highlighting a successful management approach that preserved critical ear structures.
Background: Vertebral artery (VA) stump syndrome (VASS) is an embolic source for cerebral infarction (CI) in the posterior circulation after VA occlusion.
Case Description: A 63-year-old patient with a history of hypertension presented to our emergent department with dizziness, vomiting, and gait disturbance. Head magnetic resonance imaging (MRI) showed acute CIs in the bilateral cerebellar hemispheres and the vermis.
Metastasis of pleomorphic adenoma (PA) is rare and usually presented as a locoregional recurrence developed many years after excision of the primary tumor although the PA is the most common neoplasm in the parotid gland. We described a case of a 48-year-old male with a parotid tumor with multiple enlarged ipsilateral lymph nodes which suggested a malignancy. The tumors had been neither evaluated nor excised and preoperative evaluation revealed benign PA in both lesions.

Since the introduction of video-assisted thoracoscopic surgery, the safety and effectiveness of carbon dioxide insufflation in the thoracic cavity (capnothorax) has been controversial. This study aimed to compare the safety and effectiveness of ventilation methods in bilateral video-assisted thoracoscopic extended thymectomy (BVET) with capnothorax.

Objectives: To compare the surgical outcomes of externally monitored and conventional buried flaps with the goal of determining the usefulness of external monitoring of buried flaps.
Methods: In this case-control study with propensity score matching, 30 patients were evenly divided into externally monitored buried flap and conventional buried flap groups. The total operative time for free flap reconstruction, the flap survival rate, the length of hospital stay, the initial time of a reliable visual assessment, complications, the final diet achieved, and the duration until diet initiation were compared between the groups.
