Aim: To determine sac volume based on radiological examinations in patients undergoing surgery for myelomeningocele (MMC) and to investigate the relationship of sac volume with hydrocephalus and Chiari malformation type 2 (CM) with a view to determining the optimum length of follow-up and recommend a treatment plan.
Material And Methods: The present study involved the retrospective review of radiologic examinations and medical files of 81 patients who underwent surgery for myelomeningocele between 2015 and 2022 in the neurosurgery clinic of Ankara Training and Research Hospital. Then, MMC sac volumes were measured and the statistical relationship of these measurements with the Evans Index, progressive enlargement of the ventricles after sac repair and CM was investigated.
Results: Of the 81 patients, 41 (50.6%) were boys and 40 (49.4%) were girls. The median MMC sac volume was 11,005.28 mm³ and the mean Evans index (EI) based on brain tomography performed on postnatal day1was 0.405 ± 0.146. Analysis of the relationship between the EI and MMC sac volume yielded r=0.622, p < 0.001 and showed a strong positive correlation between the two parameters at a statistical significance level of 5%. Evans Indexes based on brain tomography scans performed on postnatal day 1 showed that ventriculomegaly was present in 49 (60.5%) patients and absent in 32 (39.5%) patients. In patients who developed hydrocephalus after sac repair, there was no correlation between the day of intervention and sac volume. Mean sac volume was 28,297.36 mm³ in 28 patients with comorbid CM versus 7,600.32 mm³ in patients without CM. All children with CM required shunting.
Conclusion: Patients with larger myelomeningocele sac volume have higher risk of concomitant hydrocephalus or subsequent development of hydrocephalus after sac repair compared to patients with a smaller sac volume. These patients should definitely be evaluated for same-session intervention. Patients with a larger sac volume and/or comorbid CM should be followed up more frequently and for a longer period of time.

Introduction: HIV-1 exploits dendritic cells (DCs) to spread throughout the body via specific recognition of gangliosides present on the viral envelope by the CD169/Siglec-1 membrane receptor. This interaction triggers the internalization of HIV-1 within a structure known as the sac-like compartment. While the mechanism underlying sac-like compartment formation remains elusive, prior research indicates that the process is clathrin-independent and cell membrane cholesterol-dependent and involves transient disruption of cortical actin.

Objective: As aneurysmal disease is progressive, proximal disease progression and para-anastomotic aneurysms are complications experienced after open infrarenal abdominal aortic aneurysm repair (AAA). As such, fenestrated or branched endovascular repair (F/BEVAR) may be indicated in these patients. Data describing fenestrated endovascular aneurysm repair after prior open repair are limited to institutional databases.

This study presents a patient with a PET-CT detected residual lacrimal sac tumor who was treated with intensity modulated proton therapy (IMPT) and concurrent chemotherapy. The patient a 49-year-old male diagnosed with squamous cell carcinoma of the left lacrimal sac had under-went endoscopic surgery. Postoperative PET-CT implied tumor residual in the left lacrimal sac.

Background: The impact of completely reducing or transecting a hernia sac on seroma formation in laparoscopic surgery for lateral inguinal hernias remains debated. To date, no studies have compared the incidence of seroma in hernia sacs left untouched versus other surgical approaches. Abandoning the hernia sac involves avoiding manipulation of the inguinal canal, unlike the manipulation required for transection or reduction of the hernia sac.
