Filter Complications

Background: Patients with an inferior vena cava (IVC) filter that remains in situ encounter a lifelong increased risk of deep vein thrombosis and IVC filter complications including fracture, perforation and IVC filter thrombotic occlusion. Data on the safety of becoming pregnant with an in situ IVC filter are scarce. Objective: To evaluate the risk of complications of in situ IVC filters during pregnancy. Methods: We performed a retrospective cohort study of pregnant patients with an in situ IVC filter from a tertiary center between 2000 and 2020. We collected data on complications of IVC filters and pregnancy outcomes. Additionally, we performed a systematic literature search in MEDLINE, Embase and grey literature. Findings: We identified seven pregnancies in four patients with in situ IVC filters with a mean time since IVC filter insertion of 3 years (range 1-8). No complications of IVC filter occurred during pregnancy. Review of literature yielded five studies including 13 pregnancies in nine patients. In one pregnancy a pre-existent, until then asymptomatic, chronic perforation of the vena cava wall by the IVC filter caused major bleeding and uterine trauma with fetal loss. Overall, the complication rate was 5%. Conclusion: It seems safe to become pregnant with an indwelling IVC filter that is intact and does not show signs of perforation, but due to the low number of cases no firm conclusions about safety of in situ IVC filters during pregnancy can be drawn. We suggest imaging prior to pregnancy to reveal asymptomatic IVC filter complications.

Abstract Background: Inferior vena cava thrombosis (IVCT) is a rare clinical condition. Herein, we report eight cases of IVCT in Taiwanese patients.Methods: Eight Taiwanese patients diagnosed with IVCT between May 2012 and December 2019 were included in this study. The patients’ demographics, presenting characteristics, additional sites of venous thromboembolism, extent of IVCT, prothrombotic risk factors, and IVCT-related adverse events were evaluated.Results: All eight patients with IVCT presented with other coexisting venous thromboembolic manifestations, such as deep venous thrombosis (DVT, 100%) or pulmonary embolism (62.5%). The clinical presentations, including DVT in both lower extremities coexisting with the dilatation of the superficial veins of the abdominal wall (50%), were reported. No congenital anomalies of the inferior vena cava (IVC) were noted. Various thromboembolic risk factors, such as unretrieved IVC filters (25%), pregnancy (37.5%), lupus anticoagulants (37.5%), surgery (25%), antithrombin deficiency (12.5%), hemoglobin H disease (12.5%), and essential thrombocythemia (12.5%), were identified. All patients were administered anticoagulants. One patient (12.5%) developed post-thrombotic syndrome. No mortality was reported in our cohort. Conclusions: This is the first report of IVCT in Taiwanese patients. Typical clinical features of IVC occlusion coexisting with predisposing factors of venous thrombosis, such as lupus anticoagulants, pregnancy, or unretrieved IVC filters, could indicate a diagnosis of IVCT. Moreover, IVCT presenting as a complication resulting from the unretrieved IVC filter was observed, highlighting the potential risks of chronic indwelling filters.

Background: Inferior vena cava (IVC) filters are commonly used in China to prevent pulmonary embolisms in patients with deep vein thrombosis. However, IVC filter removal is complicated when the filter has penetrated the IVC wall and endovascular techniques usually fail. The purpose of this study was to evaluate the effectiveness and safety of retroperitoneal laparoscopic-assisted retrieval of wall-penetrating IVC filters after endovascular techniques have failed. Patients and Methods: We retrospectively evaluated a series of 8 patients who underwent retroperitoneal laparoscopic-assisted retrieval of a wall-penetrating IVC filter between December 2017 and November 2019. All patients had experienced at least 1 failure with endovascular retrieval before the study. The filters were slanted and the proximal retrieval hooks penetrated the posterior lateral IVC wall in all patients on computed tomography. Demographic information, operation parameters, and complications were recorded and analyzed. All patients were followed up for at least 12 months. Results: The procedure was successful in all patients. The median surgery time was 53.6 ± 12.7 min and the average blood loss was 45.0 ± 13.5 ml. No serious complication occurred during the patients’ hospitalization, which was an average of 6.4 days. The median follow-up time was 15.1 months, and no patient had deep vein thrombosis recurrence. Conclusions: Retroperitoneal laparoscopic-assisted retrieval is a feasible and effective technique, particularly when proximal retrieval hooks penetrate the posterior lateral wall of the IVC after endovascular techniques have failed. To some extent, the development of this technique at our institution has increased the success rate of filter removal and improved patient satisfaction.

Filter Insertion

Retrievable inferior vena cava (IVC) filters are increasingly used in patients with venous thromboembolism (VTE) who have contraindications to anticoagulant therapy. However, previous studies have shown that many retrievable filters are left permanently in patients. This study aimed to identify the common indications for IVC filter insertion, the filter retrieval rate, and the predictive factors for filter retrieval attempts. To this end, a retrospective cohort study was performed at a tertiary care center in South Korea between January 2010 and May 2016. Electronic medical charts were reviewed for patients with pulmonary embolism (PE) who underwent IVC filter insertion. A total of 439 cases were reviewed. The most common indication for filter insertion was a preoperative/procedural aim, followed by extensive iliofemoral deep vein thrombosis (DVT). Retrieval of the IVC filter was attempted in 44.9% of patients. The retrieval success rate was 93.9%. History of cerebral hemorrhage, malignancy, and admission to a nonsurgical department were the significant predictive factors of a lower retrieval attempt rate in multivariate analysis. With the increased use of IVC filters, more issues should be addressed before placing a filter and physicians should attempt to improve the filter retrieval rate.

Successful Retrieval

Background: Inferior vena cava (IVC) filters have been proven to be significantly advantageous and clinically efficacious in the prevention of deathly venous thromboembolism, but also carry long-term risks, such as device failure, filter fracture, migration, penetration into adjacent structures, etc. Retrievable filters offer the same degree of protection, and subsequently lower those risk by removing them after they aren’t needed. Unfortunately, increasing use of retrievable filters leads to one alarming trend: there’s massive number of filters that are left for an extended time. Whether the time between deployment and retrieval affects filter’s technical success of retrieval remains questionable. Here is a case of a 45-year old woman who had undergone retrievable IVC filter due to pulmonary embolism risk. The patient only came to clinician for routine follow- up once, one month after deployment. One year later, the patient felt abdominal pain and asked to remove the filter. After one failed attempt, the clinician decided to leave the filter in situ as permanent filter. Method: Literature searching was conducted in several databases (ScienceDirect, EbscoHost, and ClinicalKey) using specified keywords. Six articles that had been passed exclusion and inclusion criteria, were eventually appraised and extracted. Results: Of all six articles that are included in this study, there are no standard time of retrieval. Each study provides data regarding their attempted retrieval, successful retrieval, and dwell time. Only two articles (Uberoi et al and Glocker et al) analyze the relationship between time of retrieval and successful retrieval. Uberoi et al claims filter retrieval statistically more successful if the dwell time is less than 9 weeks, whereas Glocker et al states the procedure is considerably more successful within 3-4 months (117 days) after deployment. The reasons of retrieval failure in these studies are varied, including device angulation, filter incorporation with IVC wall, and penetration to IVC wall and adjacent structures, or significant thrombus inside the filter. Conclusion: There are no standard time of retrieval, but clinicians could follow FDA recommendation by removing the filter when it isn’t necessarily needed. However, a time span of 3-4 months between implantation and retrieval can be respectable choice to make sure the maximum chance at retrieval success.

The number of patients choosing surgical alternatives for weight reduction continues to increase. Despite common thromboembolic preventive methods, which include perioperative subcutaneous heparin injections, early mobilization, and sequential compression devices, postoperative deep vein thrombosis/pulmonary embolism remains a devastating complication after bariatric surgery. The role prophylactic inferior vena cava (IVC) filters may play in bariatric surgery remains controversial, and this article aims to address the risks and benefits of prophylactic IVC filters in high-risk bariatric patients and suggest an evidence-based algorithm for their use.
