RESUMO
BACKGROUND: The position of the catheter tip of totally implantable venous access devices (TIVAD) is a risk factor for postoperative complications. The study aim was to assess the early and late complications (EC and LC) associated with the position of the catheter tip in cancer patients. METHODS: We reviewed cancer patients who had a TIVAD placed in 2020. EC (≤ 90 days), LC (> 90 days) and risk factors for TIVAD-associated complications were assessed. The vertical mismatch of the catheter tip was compared to an "ideal position" (> 10 mm below the carina and ≥ 20 mm below the right main bronchus (RMB)) using chest x-ray, post-implantation. RESULTS: 301 patients were included. Median follow-up after TIVAD implantation was 9.4 months. All TIVAD catheters were inserted via the internal jugular vein (IJV). The mean distance between the catheter tip and the carina and the RMB was 21.3 mm and 6.63 mm respectively. In total, 11.3% patients developed EC and 5.6% had LC. An association was found between the position of the catheter tip from the carina (≤ 10 mm vs. > 10 mm) and the occurrence of EC (18.3% vs. 8.6%, p = 0.01) and for the catheter insertion side (left IJV vs. right IJV) (19.1% vs. 9.0% p = 0.02). Multivariate analysis showed that left IJV catheter insertion (OR 2.76), and a catheter tip located ≤ 10 mm below the carina (OR 2.71) are significant independent risk factors of EC. CONCLUSIONS: TIVAD catheter tip located at ≤ 10 mm below the carina, and a left-side inserted catheter, are higher risk of EC.

INTRODUCTION: Cytoreductive surgery (CRS) ± hyperthermic intraperitoneal chemotherapy (HIPEC) is the only potentially curative treatment that can improve the survival prognosis for patients with peritoneal metastasis (PM) of colorectal origin. The main independent prognostic factors are extent of disease, as measured by the Peritoneal Cancer Index (PCI), and completion of CRS (CC-0 or R1). Despite thorough preoperative work-up for selection of surgical candidates, 20%-25 % of CRS procedures are stopped after exploration during laparotomy. These patients undergo "open-and-close" procedures associated with a risk of complications and without any benefit. The aim of this study was to identify preoperative predictors of non-resectability and/or non-completion of CRS in patients with colorectal PMs who were candidates for surgery. MATERIALS AND METHODS: Retrospective, monocentric study including patients admitted for CRS ± HIPEC at the Jules Bordet Institute between January 01, 2010 and December 31, 2021. The preoperative epidemiological, pathological, clinical, radiological, and biological features of patients with unresectable disease were compared with those of patients treated with CRS. RESULTS: One hundred nineteen patients were included, 60 men and 59 women (median age 61 years). Twenty-one CRS procedures (17.65 %) were stopped during exploratory laparotomy. Statistically significant factors associated with non-completion were age (p = 0.0183), PCI (p = 0.0001), presence of sub/occlusive episode(s) prior to CRS (p = 0.0012), and multifocal-diffuse uptakes on PET-scan (p = 0.0017). CONCLUSION: Almost 18 % of patients had an "open-and-close" procedure. PCI was the major determinant of non-completion of CRS. Other predictive factors of unresectability of colorectal PM were age, the presence of sub/occlusive episodes, and PET/CT with multiple peritoneal uptakes.

Objectives: The aim of this retrospective study was to evaluate the added value of pre-procedural computed tomography angiography (CTA) prior to bronchial artery embolization for patients presenting with hemoptysis. Materials and Methods: In this retrospective study, we evaluated patients admitted for hemoptysis from 2010 to 2021 and treated by catheter-directed embolization. After establishing quality criteria for pre-procedural computed tomography (CT), patients were divided into two groups depending on their pre-procedural imaging assessment: Quality CT-angiography (QCTA group) and suboptimal pre-procedural imaging (suboptimal CTA, unenhanced or no CT evaluation; control group). Groups were compared based on radiological success, procedure-related complications, and clinical success, including cessation of hemoptysis, recurrence rates, and overall mortality. Results: We included 31 patients in the QCTA group, and 35 in the control group. Clinical success was n = 24/31 (77.4%) in the QCTA group and n = 27/35 (77.1%) in the control group (p = 0.979). Technical success was n = 37/42 (88.1%) in the QCTA group and n = 39/42 (92.86%) in the control group (p = 0.820). Overall recurrence was 10.6%. Minor complications occurred in 27.3%, and one major complication was reported.The concordance between the affected bleeding lung and the identification of pathological arteries during angiography was better in the QCTA group (p = 0.045).The average number of culprit arteries (bronchial, non-bronchial systemic arteries [NBSA] or pulmonary) in the QCTA group was not significantly higher than that in the control group. Conclusions: Preprocedural QCTA better identifies the affected bleeding lung and bleeding vessels compared to direct angiography. No difference in clinical success, complications, recurrence rates, or mortality was observed.
