Aim: To prove the superiority of the electromagnetic (EM) neuronavigation technique to increase the accuracy of intraventicular shunt catheter placement, and to reduce accompanying complications.
Material And Methods: A total of 21 patients with hydrocephalus [age range (years): 53-84] were studied. All of them had undergone thin-slice, navigation-compatible, computed tomography (CT) preoperatively. Shunt surgery was performed under the guidance of EM neuronavigation technology. All patients underwent follow-up CT the next day to evaluate catheter tip placement and were followed up at 1, 3, 6, and 12 months.
Results: All catheter tips were placed properly in front of the foramen of Monro in the desired position, except in one case in which the tip migrated to the perimesencephalic cistern and underwent reoperation in the early postoperative period. No complications due to infection and obstruction were observed in the medium- and long-term follow-ups. The complication rate due to the incorrect catheter positioning was 4.76% of the total cases.
Conclusion: The placement of the ventricular catheter under EM-guided navigation technology reduces the proximal-end failure caused by malpositioning, obstruction, and infection.

Background: Temporary transvenous pacing (TTP) is a common procedure, predominantly performed in the catheterization laboratory (cath lab) because of presumed lower complication rate. This study aims to evaluate the efficacy and safety of TTP placement in the ICU compared to TTP placement in the cath lab.
Methods: This retrospective, real-life study included all patients requiring TTP in a tertiary care ICU between 2019 and 2022.

Hematology patients require central venous catheters for cancer treatment and nutrition, which increases their risk of intravascular device-associated bacteremia. In the absence of recent data, we investigated intravascular device-associated bacteremia in this specific context. A three-month surveillance was conducted annually in 27 hematology wards, using a protocol derived from the HAI-Net ICU ECDC protocol (2020-2024).

Postoperative fever following neuroendoscopic procedures has been well-documented, yet specific differentiation based on the nature and site of the procedure remains lacking. Given the anatomical involvement of the hypothalamus in temperature regulation, we propose that endoscopic third ventriculostomy (ETV) may have a distinct impact on postoperative fever. This study aims to investigate this phenomenon.

The formula-based estimation of the right internal jugular venous (IJV) catheterization depth can be inaccurate when using ultrasound guidance. External landmark-based and radiological landmark-based methods have been proposed as alternatives to estimate the insertion depth. This study aimed to evaluate these methods using transesophageal echocardiography (TEE)-guided insertion depth as the reference.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.
