Aim: CSF shunt failure is still a frequent problem in children. This prospective study was designed for focusing symptoms and reasons of shunt failure. We also especially focused on the mechanical reasons of shunt failure.
Material And Methods: We focused on the causes of shunt failures, and the symptoms and signs in patients who were operated for shunt malfunction between January 1, 2001 and December 31, 2005 in the neurosurgery department. All examination and operative data were collected prospectively. Evaluation of these data was with the chi-square and Fisher exact tests.
Results: After the evaluation of data on 111 patients and 153 revision procedures, the major symptoms in this group were vomiting (62.16%), somnolence (59.45%) and headache (48.64%). In the majority of the shunt revisions (115 operations, 75.2% of the all 153 procedures), one or more mechanical problems of the shunt systems were identified in surgery.
Conclusion: Shunt failures in children sometimes appear with very unusual symptoms. Also, probable structural problems of the shunt systems seem very important for shunt failure according to patient characteristics and etiology of the hydrocephalus. A systematic approach including CT, shunt series and abdominal ultrasound is needed to rule out shunt malfunction.

Department of Neurosurgery, National Institute of Mental Health and Neurosciences, Bengaluru, India. Electronic address:
Purpose: Arachnoid cysts constitute approximately 1 % of intracranial mass lesions, with quadrigeminal cistern arachnoid cysts being 5-18 % of those. This study presents a series of 31 cases of quadrigeminal cistern arachnoid cysts, constituting the most extensive series reported to date.
Methods: A retrospective analysis was conducted on 31 patients diagnosed with quadrigeminal cistern arachnoid cysts, focusing on clinical presentation, demographics, treatment approaches, and outcomes.
Systematic follow-ups were not associated with reduced acute ventriculoperitoneal shunt dysfunction in infancy.

Department of Women's and Children's Health, Uppsala University, Uppsala, Sweden.
Aim: Hydrocephalus surgery with a ventriculoperitoneal shunt is a life-saving treatment, but it has been associated with a high risk of dysfunction and complications. We investigated whether infants who received a ventriculoperitoneal shunt below 12 months of age had a reduced risk of acute shunt dysfunction if they were included in a structured follow-up programme.
Methods: A population-based, retrospective chart review was performed at Uppsala University Children's Hospital, Sweden.

Background: In cirrhotic patients, portal hypertension increases mortality after surgery. We evaluated the impact of pre-operative transjugular intrahepatic portosystemic shunt (TIPS) on the outcomes of bariatric surgery in cirrhosis.
Methods: Multicentric retrospective cohort.
Persistent trigeminal artery variant as a duplicate anterior inferior cerebellar artery.

Department of Neurosurgery, Nakamura Memorial Hospital, South 1, West 14, Chuo-ku, Sapporo, 060-8570, Hokkaido, Japan.
Purpose: A persistent trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Persistent trigeminal artery variants (PTAVs) terminate in the cerebellar arteries without connecting to the basilar artery; of these, the anterior inferior cerebellar artery (AICA) is the most common. AICA duplication is frequently observed.

Objective: The key to increasing the success rate of limb preservation lies in timely restoration of the blood supply to the severed limb, This study examines the clinical effect of a disposable intravenous infusion device as a temporary vascular shunt device which can quickly restore blood circulation in the replantation of severed limbs.
Methods: A retrospective review of all amputated major limbs in our department from May 2005 to May 2022. Patients treated with intravenous infusion tubes as temporary vascular shunt devices were included in group A(shunt group ) and those who could not use temporary intravascular shunt devices were included in group B (no shunt group).
