ABSTRACT

Patients with end-stage renal disease (ESRD) often will ultimately require dialysis to survive. One type of dialysis is peritoneal dialysis (PD), which utilizes the vessel-rich peritoneum as a semi-permeable membrane to filter blood. In order to perform PD, a tunneled catheter must be placed through the abdominal wall and into the peritoneal space, with ideal positioning of the catheter within the most dependent portion of the pelvis, represented by the rectouterine or rectovesical space in women and men, respectively. There are several approaches to PD catheter insertion, including open surgical, laparoscopic surgical, blind percutaneous, and image-guided with the use of fluoroscopy techniques. Interventional radiology (through the use of image-guided percutaneous techniques) is an infrequently utilized resource to place PD catheters, and offers real-time imaging confirmation of catheter positioning with similar outcomes to more invasive surgical catheter insertion approaches. Although the vast majority of dialysis patients receive hemodialysis instead of peritoneal dialysis in the United States, some countries have moved towards a "Peritoneal Dialysis First" initiative, prioritizing initial PD, as it is less burdensome on healthcare facilities as it can be performed at home. In addition, the outbreak of the COVID-19 pandemic has produced shortages of medical supplies and delays in care delivery worldwide, while simultaneously generating a shift away from in-person medical visits and appointments. This shift may be met with more frequent utilization of imaged-guided PD catheter placement, reserving surgical and laparoscopic placement for complex patients who may require omental periprocedural revisions. This literature review outlines a brief history of PD, the various techniques of PD catheter insertion, patient selection criteria, and new COVID-19 considerations, in anticipation for the increased demand for PD in the United States.

ABSTRACT

BACKGROUND: Kidney biopsy is the most vital tool guiding a nephrologist in diagnosis and treatment of kidney disease. Over the last few years, we have seen an increasing number of kidney biopsies being performed by interventional radiologists. The goal of our study was to compare the adequacy and complication rates between kidney biopsies performed by interventional radiology versus nephrology.  METHODS : We performed a single center retrospective analysis of a total of all kidney biopsies performed at our Institution between 2015 and 2021. All biopsies were performed using real-time ultrasound. Patients were monitored for four hours post biopsy and repeat ultrasound or hemoglobin checks were done if clinically indicated. The entire cohort was divided into two groups (Interventional radiology (IR) vs nephrology) based on who performed the biopsy. Baseline characteristics, comorbidities, blood counts, blood pressure, adequacy of the biopsy specimen and complication rates were recorded. Multivariable logistic regression was used to compare complication rates (microscopic hematuria, gross hematuria and need for blood transfusion combined) between these two groups, controlling for covariates of interest. ANCOVA (analysis of variance, controlling for covariates) was used to compare differences in biopsy adequacy (number of glomeruli per biopsy procedure) between the groups. RESULTS: 446 kidney biopsies were performed in the study period (229 native and 147 transplant kidney biopsies) of which 324 were performed by IR and 122 by nephrologist. There was a significantly greater number of core samples obtained by IR (mean = 3.59, std.dev. = 1.49) compared to nephrology (mean = 2.47, std.dev = 0.79), p < 0.0001. IR used 18-gauge biopsy needles while nephrologist exclusively used 16-gauge needles. IR used moderate sedation (95.99%) or general anesthesia (1.85%) for the procedures more often than nephrology, which used them only in 0.82% and 0.82% of cases respectively (p < 0.0001). Trainees (residents or fellows) participated in the biopsy procedures more often in nephrology compared to IR (97.4% versus 69.04%, p < 0.0001). The most frequent complication identified was microscopic hematuria which occurred in 6.8% of biopsies. For native biopsies only, there was no significant difference in likelihood of complication between groups, after adjustment for covariates of interest (OR = 1.01, C.I. = (0.42, 2.41), p = 0.99). For native biopsies only, there was no significant difference in mean number of glomeruli obtained per biopsy procedure between groups, after adjustment for covariates of interest (F(1,251) = 0.40, p = 0.53). CONCLUSION: Our results suggest that there is no significant difference in the adequacy or complication rates between kidney biopsies performed by IR or nephrology. This conclusion may indicate that kidney biopsies can be performed safely with adequate results either by IR or nephrologists depending on each institution's resources and expertise.

ABSTRACT

Pulmonary artery pseudoaneurysm (PAP) is a rare cause of life-threatening hemoptysis and tends to develop in the setting of infection, neoplasm, or trauma. Successful endovascular coil embolization has demonstrated effectiveness in treating PAPs and is now the treatment of choice for these patients. Vascular supply to PAPs is highly variable and often requires embolization of both the systemic and pulmonary feeding vessels. This is a case report of a successful transcatheter coil embolization of a complex PAP with a thyrocervical trunk-pulmonary arterial fistula in a patient with massive hemoptysis in the setting of advanced cystic fibrosis.

ABSTRACT

Pancreatic pseudocyst formation, arterial pseudoaneurysm, and splanchnic vein thrombosis are complications of chronic pancreatitis that account for significant morbidity and mortality in this patient population. While the short-term utility of timely endovascular intervention for treating the vascular complications of chronic pancreatitis have been relatively well documented, there is a paucity of longitudinal follow-up in this patient population, therefore making it difficult to predict the long-term efficacy of these interventions. This report details a case of a gastroduodenal artery pseudoaneurysm embolization followed by symptomatic superior mesenteric vein chronic thrombosis treated by stent dilatation in a patient with chronic pancreatitis, with 7 years clinical and imaging follow-up.

ABSTRACT

Pelvic fractures and sacroiliac joint (SI) diastasis are debilitating injuries which can drastically decrease an individual's functional capacity, and lead to significant morbidity and mortality. In younger, healthier populations, pelvic fractures are usually the result of sudden traumatic forces, such as a motor vehicle collision. Atraumatic pelvic fractures can also occur, and are most commonly due to age related changes and osteoporosis. Even with prompt surgical management, pelvic fractures often result in a host of challenging complications such as disruption of the SI joint with subsequent limitations in mobility and chronic pain. In this case report, we present a novel treatment of SI diastasis, secondary to corticosteroid induced osteoporosis and pelvic fractures. We performed percutaneous bilateral poly-methyl-methacrylate (PMMA) SI joint fusions under CT-guidance. Here we describe a case of bilateral SI joint CT guided percutaneous arthroplasty for osteoporotic SI joint diastasis and pelvic fractures, resulting in a rapid resolution of SI joint pain and restoration of the ability to ambulate in a previously wheelchair-bound patient. This may be of particular benefit in patients who are poor surgical candidates who experience osteoporotic fractures and would be otherwise unable to receive definitive operative management of their pathologic fractures.

ABSTRACT

Aortic injury is a frequently encountered condition that can present as a life-threatening emergency. When this injury occurs in the retroperitoneal portion of the aorta, it can be difficult to diagnose and treat because of the location. Although surgical repair remains the mainstay of treatment, surgery might not be an option for some patients. We have presented a case of a 54-year-old nonoperative candidate who had experienced iatrogenic retroperitoneal abdominal aortic rupture with pseudoaneurysm formation. The patient was successfully treated with the novel use of a proven technique: direct percutaneous embolization of the pseudoaneurysm sac via a translumbar approach under image guidance.

ABSTRACT

Interventional radiology (IR) is an underutilized resource for the placement and management of tunneled peritoneal dialysis (PD) catheters, as only about 5% of PD catheters are placed by using IR. PD is a cost-effective and physiologically beneficial alternative to hemodialysis (HD) with an increased survival benefit and lower complication rate than HD. As a home dialysis therapy, patients who undergo PD experience many advantages over patients who undergo HD, including a greater sense of well-being and quality of life. The author explains the history, need, rationale, benefits, complications, patient selection, preprocedure patient evaluation and preparation, catheter selection, procedural directives, and management strategies of IR involvement in tunneled PD catheter placement. Surgical and non-image-guided placement techniques and pitfalls are also discussed, and their benefits and limitations are compared with the cost-effective percutaneous image-guided IR technique. Specific attention to image-documented placement of the PD catheter coil into the retrovesical or retrouterine space is emphasized for optimal PD catheter function, as the retrovesical or retrouterine space is the most dependent portion of the peritoneal space and is void of omentum and small bowel. These features increase the functional ability of the PD catheter to effectively exchange the dialysate fluid and avoid complications such as omental wrap. IR, as an image-based specialty, is well positioned to evaluate for other complications of tunneled PD catheters such as migration, catheter kink and obstruction, and catheter leak. The demand for PD is predicted to increase in the future, and IR is strategically situated to become a leader in tunneled PD catheter placement and management. Published under a CC BY 4.0 license.

ABSTRACT

OBJECTIVE. The purpose of this article was to evaluate the feasibility and efficacy of percutaneous fluoroscopic-guided stone retrieval from the cystic duct and antegrade common bile duct (CBD) stone advancement into the duodenum exclusively through a cholecystostomy tube. MATERIALS AND METHODS. Twenty-one patients with acute cholecystitis and choledocholithiasis or an impacted cystic duct stone who underwent percutaneous cholecystostomy tube placement were retrospectively enrolled in this study. The patients had a contra-indication for cholecystectomy (17 patients because of comorbidities and one who declined surgery) or had failed endoscopic retrograde stone removal attempts (three patients). RESULTS. The 21 patients underwent subsequent percutaneous CBD (17 patients) and cystic duct (nine patients) stone removal on follow-up sessions through the percutaneous cholecystostomy track using moderate sedation. A total of 32 stone removal procedures were performed. Seventeen patients underwent balloon dilatation sphincterotomy, after which the CBD stones were pushed forward into the duodenum using a compliant balloon. Seven patients also had stone removal from the cystic duct by a stone retrieval basket. The primary technical success rate for removal of all CBD and cystic duct stones was 76%. The secondary technical success rate was 100%. The clinical success rate was 74%. All patients tolerated the procedures well without major complication. The clinical follow-up interval ranged from 2 to 2310 days (median, 30 days), with no incidence of postprocedural complications. CONCLUSION. Percutaneous transcholecystic common bile and cystic duct stone removal through an existing cholecystostomy access is a safe and effective procedure that is well tolerated.

ABSTRACT

An excluded calyx is a rare, acquired urologic condition where there is discontinuity between a portion of the renal collecting system with the remainder of the collecting system. Re-establishment of reliable long-term communication between the excluded calyx and the remaining collecting system is crucial for preservation of renal function and possible relief of symptoms. In this manuscript, we discuss two such cases where a previously undescribed novel procedure is used for treatment of this uncommon condition, where percutaneous antegrade transcatheter techniques were used to establish long-term urinary drainage. The first case discusses an excluded calyx in a 17-year-old male who suffered left renal injury after a high speed motor vehicle accident, where the kidney was divided by the injury and subsequently required creation of a neoinfundibulum in order to maintain continuity of the collecting system. The second case involves a 39-year-old female who underwent resection of a renal cell carcinoma, later developing an excluded calyx where radiofrequency wire recanalization was performed and the neoinfundibular track underwent serial retrograde balloon dilation, resulting in a continuous collecting system. Both patients have done well for more than 2 years after neoinfundibulum creation, showing that this novel technique should be considered a viable and safe procedure in the treatment of this rare condition.

ABSTRACT

Pulmonary embolism (PE) is a major cause of morbidity and mortality in the United States and usually occurs secondary to venous thromboembolism. Inferior vena cava (IVC) filters are minimally invasive intravascular devices placed in patients who are at increased risk for venous thromboembolism leading to PE, however, has a contraindication to medical anticoagulation therapy. The longest reported case of a retrievable IVC filter has remained in place and successfully removed in a living patient has been 4753 days (13 years). We present a case of an uneventful, successful IVC removal with a dwell time of 6033 days (16 years).

ABSTRACT

OBJECTIVE: The objective of this study was to develop a machine deep learning algorithm for endoleak detection and measurement of aneurysm diameter, area, and volume from computed tomography angiography (CTA). METHODS: Digital Imaging and Communications in Medicine files representing three-phase postoperative CTA images (N = 334) of 191 unique patients undergoing endovascular aneurysm repair for infrarenal abdominal aortic aneurysm (AAA) with a variety of commercial devices were used to train a deep learning pipeline across four tasks. The RetinaNet object-detection convolutional neural network (CNN) architecture was trained to predict bounding boxes around the axial CTA slices that were then stitched together in two dimensions into a smaller region containing the aneurysm. Multiclass endoleak detection and segmentation of the AAA, endograft, and endoleak were performed on this smaller region. Segmentations on a single randomly selected contrast from each scan included 33 full and 68 partial segmentations for endograft and AAA and 99 full segmentations for endoleak. A modified version of ResNet-50 CNN was used to detect endoleak on individual axial slices. A three-dimensional U-Net CNN model was trained on the task of dense three-dimensional segmentation and used to measure diameter and volume with a specially designed loss function. We made use of fivefold cross-validation to evaluate model performance for each step, splitting training and testing data at each fold, such that multiple scans from the same patient were preserved with the same fold. Algorithm predictions for endoleak were compared with the radiology report and with a subset of CTA images independently read by two vascular specialists. RESULTS: The localization portion of the network accurately predicted a region of interest containing the AAA in 99% of cases. The best model of binary endoleak detection obtained an area under the receiver operating characteristic curve of 0.94 ± 0.03 with an optimized accuracy of 0.89 ± 0.03 on a balanced data set. An introduced postprocessing algorithm for determining maximum diameter was used on both the predicted AAA segmentation and ground truth segmentation, predicting on average an absolute diameter error of 2.3 ± 2.0 mm by 1.4 ± 1.7 mm for each measurement, respectively. The algorithm measured AAA and endograft volume accurately (Dice coefficient, 0.95 ± 0.2) with an absolute volume error of 10.1 ± 9.1 mL. The algorithm measured endoleak volume less accurately, with a Dice score of 0.53 ± 0.21 and an average absolute volume error of 1.2 ± 1.9 mL. CONCLUSIONS: This machine learning algorithm shows promise in augmenting a human's ability to interpret postoperative CTA images and may help improve surveillance after endovascular aneurysm repair. External validation on larger data sets and prospective study are required before the algorithm can be clinically applicable.

ABSTRACT

A duplicated collecting system (DCS) is a common anatomical variant of the kidney. As surgeons now perform more donor cadaveric transplants than in the past, the discovery of an occluded DCS may occur in the post-transplant setting. Over a dozen articles have reported on the use of DCS in the renal transplant setting. However, to our knowledge, this case report is the first to describe the creation of a ureterocystostomy with the use of a radiofrequency (RF) guide wire, involving a previously unidentified DCS in a transplanted kidney.

ABSTRACT

PURPOSE: To develop a new adverse event (AE) classification for the interventional radiology (IR) procedures and evaluate its clinical, research, and educational value compared with the existing Society of Interventional Radiology (SIR) classification via an SIR member survey. MATERIALS AND METHODS: A new AE classification was developed by members of the Standards of Practice Committee of the SIR. Subsequently, a survey was created by a group of 18 members from the SIR Standards of Practice Committee and Service Lines. Twelve clinical AE case scenarios were generated that encompassed a broad spectrum of IR procedures and potential AEs. Survey questions were designed to evaluate the following domains: educational and research values, accountability for intraprocedural challenges, consistency of AE reporting, unambiguity, and potential for incorporation into existing quality-assurance framework. For each AE scenario, the survey participants were instructed to answer questions about the proposed and existing SIR classifications. SIR members were invited via online survey links, and 68 members participated among 140 surveyed. Answers on new and existing classifications were evaluated and compared statistically. Overall comparison between the two surveys was performed by generalized linear modeling. RESULTS: The proposed AE classification received superior evaluations in terms of consistency of reporting (P < .05) and potential for incorporation into existing quality-assurance framework (P < .05). Respondents gave a higher overall rating to the educational and research value of the new compared with the existing classification (P < .05). CONCLUSIONS: This study proposed an AE classification system that outperformed the existing SIR classification in the studied domains.

ABSTRACT

PURPOSE: To determine if hepatic venous pressure gradient (HVPG) correlates with advanced hepatic fibrosis, as a complement to transjugular (transvenous) core needle liver biopsy. MATERIALS AND METHODS: After institutional review board approval, a retrospective review was conducted on 340 patients who underwent transjugular (transvenous) core needle liver biopsy with concurrent pressure measurements between 6/1/2007 and 6/1/2013. Spearman correlation and linear regression were performed. A receiver operating characteristic (ROC) curve was created and sensitivity, specificity, predictive values and likelihood ratios were calculated. RESULTS: Indications included hepatitis C, abnormal liver function tests, non-alcoholic steatohepatitis, autoimmune hepatitis, and cirrhosis, among others. Biopsies showed stage 1 or 2 fibrosis in 15.6% each, stage 3 fibrosis in 21.6%, stage 4 fibrosis in 40.7%, and no fibrosis in 6.5%. Mean HVPG was 6.5 mm Hg (SD 5.0) with a range of 0-26 mm Hg. Spearman correlation coefficient for association between HVPG and fibrosis stage was 0.561 (p < 0.001). R2 on linear regression was 0.247 (p < 0.001). ROC curve for the prediction of stage 4 fibrosis had an area under the curve of 0.79 (95% CI 0.73-0.85). HVPG of ≥6 mm Hg had a sensitivity of 71.3%, specificity of 79.6%, positive predictive value of 70.5%, negative predictive value of 80.2%, positive likelihood ratio of 3.49 (95% CI 2.45-4.97) and negative likelihood ratio of 0.36 (95% CI 0.26-0.50) for diagnosis of stage 4 fibrosis. CONCLUSIONS: HVPG correlates with stage 4 (advanced) hepatic fibrosis.

ABSTRACT

Published reports indicate low retrieval rates for retrievable inferior vena cava (IVC) filters. We performed a historic-controlled study of a 5-year intervention (March 2007 to February 2012) to improve IVC filter retrieval rates at a university medical center serving a rural area. All adults with a retrievable filter placed were included, except those with a life expectancy <6 months. The intervention included initial verbal counseling and printed educational materials, correspondence after discharge, and a hematology consultation. The control group included patients with retrievable filters placed in the 15 months preceding study initiation. In the control group, 116 filters were placed and 27 (23%) were removed, compared to 378 filters placed and 169 (45%) removed during the intervention. Adjusting for patient characteristics, the odds ratio of retrieval during the intervention was 3.03 (95% CI 1.85-4.27) compared to the control period. An intervention including patient education and hematology follow-up appeared to significantly improve IVC filter retrieval rates.

ABSTRACT

Adventitial cystic disease (ACD), also known as cystic mucoid or myxomatous degeneration, is a rare vascular disease mainly seen in arteries. Seventeen cases have been reported in the world literature. We report the first known case of ACD successfully treated with percutaneous image-guided ethanol sclerosis. Computed tomography showed a cystic mass adherent to the wall of the common femoral vein. An ultrasound examination revealed a deep venous thrombosis of the leg, secondary to extrinsic compression of the common femoral vein. Three years prior to our procedure, the cyst was aspirated, which partially relieved the patient's symptoms. Over the following 3 years the patient's symptoms worsened and a 10-cm discrepancy in thigh size developed, in addition to the deep venous thrombosis associated with lower-extremity edema. Using ultrasound guidance and fluoroscopic control, the cyst was drained and then sclerosed with absolute ethanol. The patient's symptoms and leg swelling resolved completely within several weeks. Follow-up physical examination and duplex ultrasound 6 months following sclerosis demonstrated resolution of the symptoms and elimination of the extrinsic compression effect of the ACD on the common femoral vein.

ABSTRACT

Standard therapy for frostbite has been unaltered for more than 20 years. Recently there have been reports of improved outcomes with the addition of a vasodilator to intra-arterial thrombolytic therapy. We report the case of severe frostbite of the hands successfully treated with transcatheter intra-arterial tPA after papaverine infusion in a 37-year-old man. Upper extremity and hand angiography within 16 h of the insult showed thrombotic occlusive disease and vasospasm. Intra-arterial catheters were placed in the brachial arteries and a papaverine infusion was initiated, followed by intra-arterial tPA thrombolysis. Follow-up examination at 4 months revealed full hand function and complete resolution of symptoms.

ABSTRACT

Transcatheter embolization of the uterine arteries for symptomatic fibroid disease has become an increasingly important alternative treatment. It is highly effective and well tolerated by most patients. Most notably, uterine artery embolization is associated with a short recovery period and is uterine sparing. To ensure the best chance for a safe and successful procedure, Interventional Radiologists should have familiarity with uterine artery anatomy, state of the art embolization techniques, and optimal patient selection and post procedure management.
