Anomalous venous collaterals in Apert and Crouzon syndromes and their relationship to ventricle size and increased intracranial pressure.
J Neurosurg Pediatr
November 2024
3Neurosurgery, Erasmus University Medical Center, Rotterdam, The Netherlands.
Objective: The exact association between the frequently present anomalous intracranial venous vasculature, emissary collaterals, ventriculomegaly, and increased intracranial pressure (ICP) in children with Apert and Crouzon syndromes remains an enigma. This study aimed to evaluate the association between the aberrant venous system and ventricle size and increased ICP, and to assess the development of the venous structures over time.
Methods: This retrospective cohort study included all patients with Apert or Crouzon syndrome with available CT venography (CTV) scans of the brain.
Identifying idiopathic intracranial hypertension in a hospital-based chronic headache population: Utility of magnetic resonance imaging, magnetic resonance venography and trans-orbital sonography.

Article Synopsis
- Chronic headaches can often stem from cerebro-spinal fluid issues, with Idiopathic Intracranial Hypertension (IIH) being a key example that presents with headaches and vision problems along with signs like papilledema.
- In a study of 168 headache patients, 141 were evaluated, revealing that 27% had IIH, typically characterized by specific headache types, age, and body mass index.
- Diagnostic methods such as fundus examination and MRI/MR venography prove effective in detecting IIH, even identifying cases lacking typical signs like papilledema.
Lumbar puncture opening pressure (LPOP) exceeding 250mmHO is key in diagnosing idiopathic intracranial hypertension (IIH), per revised Friedman's criteria. Some patients do not meet LPOP criteria (with or without papilledema), despite having IIH-related symptoms and neuroimaging findings. This study aimed to investigate the radiological findings and clinical symptoms in patients suspected of having IIH without meeting the LPOP criteria.

Cardiovasc Intervent Radiol
September 2024
Interventional Radiology, Department of Radiology, University of Wisconsin-Madison, 600 Highland Avenue, Madison, WI, 53792, USA.
Purpose: Left renal vein compression syndrome (LRVCS) remains a challenging diagnosis. This study aimed to correlate imaging and hemodynamic findings with clinical outcomes for patients with LRVCS.
Materials And Methods: A retrospective review of 66 renal venography procedures with or without intravascular ultrasound (IVUS) was performed from 2017 to 2023 at a single institution.
Comparison of the rate of concomitant proximal venous stenosis between the upper and lower extremities in patients with secondary lymphedema undergoing lymphaticovenous anastomosis.

Department of Plastic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea. Electronic address:
Article Synopsis
- The study examines how iatrogenic proximal venous stenosis (narrowing of veins due to medical procedures) affects outcomes in patients with secondary lymphedema undergoing lymphaticovenular anastomosis (LVA).
- It analyzed 211 patients and found a higher incidence of proximal venous stenosis in the upper extremities (32.5%) compared to the lower extremities (7.8%), along with a greater need for endovascular intervention in upper extremities.
- Key risk factors for venous stenosis were identified as older age and having upper extremity lymphedema, emphasizing the importance of preoperative evaluations for these patients before surgery.
