ABSTRACT
Purpose: The midline catheter (MC) is a peripheral venous access device with the catheter tip located in the axilla and available for mid-term intravenous (IV) therapy. This study evaluated the efficacy and clinical outcomes associated with the placement of MCs with an integrated wire-accelerated Seldinger technique for IV access. Materials and Methods: A retrospective review was conducted at a single center in South Korea between March 2020 and July 2020. Consecutive patients in whom MC insertions were performed by vascular surgeons were enrolled. The outcomes included catheter indwelling time and incidence of catheter-related adverse events. Results: Ninety-five patients (117 catheters) were included in the study. The total indwelling time was 1,964 days, with a median of 16.7 days (range, 0-76). The complication-free catheter rates at 5 and 28 days were 92.9% and 65.5%, respectively. Overall, 32 (27.4%) catheters were removed due to complications; however, major complications, such as symptomatic deep venous thrombosis and catheter-induced bloodstream infections, were confirmed in only 3 (2.6%) catheters. A common reason for premature catheter removal is inadvertent removal owing to patient inattention. A high body mass index and female sex were identified as risk factors for short indwelling times and complicated premature catheter removal. Conclusion: MC insertion is a simple and operator-friendly procedure with a low rate of major complication. It enables mid-term IV treatment through a single procedure if there are no specific complications, thereby improving quality of life of patients during hospital stay.
ABSTRACT
PURPOSE: This retrospective study aimed to compare the clinical outcomes between hybrid surgical thrombectomy (ST) and AngioJet pharmacomechanical thrombectomy (PMT) for thrombotic occlusion of arteriovenous graft. MATERIALS AND METHODS: This study enrolled patients who underwent either hybrid ST or AngioJet PMT in Presbyterian Medical Center from July 2018 to December 2018. We primarily compared the technical and clinical success rates between the two groups immediately after the procedures. Subsequently, the postprocedure clinical outcomes, including the primary and secondary patency rates and complications, were also compared. RESULTS: The hybrid ST group had a significantly higher bleeding amount than the AngioJet PMT group (P=0.02). The technical and clinical success rates were 96.7% and 93.3% in the AngioJet PMT group and 100% and 100% in the hybrid ST group, respectively. There was no significant difference in complications between the groups. The primary and secondary patencies at 12 months were not statistically different between the groups. CONCLUSION: Comparable clinical outcomes were observed between the AngioJet PMT and hybrid ST groups, highlighting an equivalent efficacy of these two methods. Although the cost is more expensive, AngioJet PMT lowered the bleeding amount. Therefore, it can be considered in selected patients who are at risk of bleeding or reluctant to surgery.
ABSTRACT
INTRODUCTION: Recently, the incidence of ductal carcinoma in situ (DCIS), a noninvasive breast malignancy, has increased. This has resulted in an increase in the incidence of breast-conserving surgery (BCS). Numerous studies have suggested that intraoperative frozen section analysis (IFSA) could reduce the rate of additional excisions required to obtain adequate resection margins. However, DCIS is a known risk factor for positive margin status during BCS. Furthermore, some authors have concluded that IFSA may not be reliable for the detection of DCIS. AIM: The aim of this study was to evaluate the safety and efficacy of IFSA in patients with DCIS. METHODS: The operative and pathological reports of patients with DCIS, who underwent BCS at our institute between 2006 and 2015, were retrospectively reviewed. The results of IFSA and the pathological findings of final reanalyzed frozen tissue specimens were analyzed. RESULTS: In total, 25 patients were included in our analysis. None of the patients required additional operations. The correct diagnosis rate for IFSA was 89.6%, with a sensitivity and specificity of 60.0% and 95.8%, respectively. CONCLUSION: IFSA could be beneficial for determining safety resection margins in patients with DCIS.
ABSTRACT
PURPOSE: This study aimed to compare the efficacy of two different catheters in hybrid surgery for salvage of thrombosed hemodialysis accesses. MATERIALS AND METHODS: The hybrid salvage procedure (surgical thrombectomy followed by endovascular angioplasty) of the thrombosed hemodialysis access, was performed using adherent clot (AC) catheter in 140 cases and Fogarty balloon catheter in 68 cases. Procedure-related outcomes such as the clot removal status, clinical success, complications, and primary patency rates were analyzed retrospectively. RESULTS: The proportion of cases with good clot removal scores in the AC catheter and Fogarty balloon catheter groups was 77.9% and 91.2%, respectively (P=0.018). Clinical success was achieved in 90.7% of the cases in the AC catheter group and in 98.5% of the cases in the balloon catheter group (P=0.035). The mean patency rates of the two groups were 50.7% and 63.2% at 3 months, 40.7% and 47.1% at 6 months, and 17.9% and 19.1% at 12 months. The complication rates (12.1% and 5.9%) and primary patency rates between the two catheters were not statistically different (P=0.328). On the analysis of the patency rate on access type of autologous (P=0.169) and prothetic graft (P=0.423), there was no significant difference between the two catheter groups. CONCLUSION: In terms of clot removal and clinical success, the AC catheter did not demonstrate better outcomes than the Fogarty balloon catheter. However, primary patency was not related to the type of catheter. Adherent clot catheter can be a useful alternative to Fogarty balloon catheter for thrombosed hemodialysis access.
