Direct superior sagittal sinus puncture via a surgical burr hole for curative embolization of the complex transverse-sigmoid sinus dural arteriovenous fistula: How I do it.

BACKGROUND: Transvenous embolization of high-grade dural arteriovenous fistulas (dAVFs) is challenging particularly when the direct sinus access is favorable due to the complex venous anatomy which prohibits endovascular access via the transfemoral approach. METHOD: The procedure was conducted in the hybrid operating suite, where a burr hole was performed, followed by direct catheterization of the superior sagittal sinus. Coil embolization was then executed to achieve complete obliteration of the fistula. CONCLUSION: The direct puncture of the superior sagittal sinus is a safe and effective method for treating complex dAVFs. This approach grants access to the fistula channel which facilitates curative embolization.

Bilateral Low-Flow Type-D Dural Carotid-Cavernous Fistula: Diagnosis and Treatment with 3D Time-of-Flight Magnetic Resonance Angiography.

BACKGROUND Carotid-cavernous fistula (CCF) is a rare, atypical vascular shunt between the carotid arterial system and the venous channels of the cavernous sinus, classified according to the shunt's anatomy, by etiology (resulting from trauma or occurring spontaneously), or by hemodynamic characteristics (such as low- or high-flow fistulas). CASE REPORT A 62-year-old female patient with poorly controlled arterial hypertension presented with bilateral periorbital edema, conjunctival chemosis, ophthalmoplegia, diplopia, and diminished visual acuity. On magnetic resonance angiography (MRA), abnormal arterial flow along the cavernous sinuses was noted, suggestive of bilateral CCF. The diagnosis of indirect dural low-flow CCF (Barrow Type D) was later confirmed by digital subtraction angiography, with feeding arteries from intracavernous internal carotid artery branches, and meningeal branches of the external carotid artery, draining bilaterally to ophthalmic veins, the intracavernous sinus, and the inferior petrosal sinus. The patient was successfully treated with endovascular embolization. At 7-month follow-up, no residual arteriovenous shunting was detected. This case highlights the importance of non-invasive radiological methods for CCF, and presents rarely published radiological findings of bilateral Type-D dural CCFs on 3-dimensional time-of-flight MRA with post-treatment MRA follow-up. CONCLUSIONS Regardless of the patient's history of possible trauma, a patient presenting with bilateral periorbital edema, conjunctival chemosis, ophthalmoplegia, diplopia, and diminished visual acuity should have a spontaneous bilateral CCF investigated to prevent delayed treatment. Experienced neuroradiologists are needed to accurately detect indirect CCF, since this condition often does not demonstrate classic symptoms.

Post-traumatic canalicular fistula: description and review of literature - SALDO update study (SUP) - paper II.

PURPOSE: To discuss the clinical spectrum and management strategies in patients with post-traumatic canalicular fistula (PTCF). METHODS: Retrospective, interventional case series of consecutive patients diagnosed with PTCF over a 6-year study period between June 2016 and June 2022. The demographics, mode of injury, location, and communication of the canalicular fistula were noted. The outcomes of several management modalities including dacryocystorhinostomy, lacrimal gland therapies, and conservative approaches were assessed. RESULTS: Eleven cases with PTCF over the study period were included. The mean age at presentation was 23.5 years (range: 6-71 years), with male: female ratio of 8:3. The median time interval between trauma to presentation at the Dacryology clinic was 3 years (range: 1 week to 12 years). Seven had iatrogenic trauma and four had the canalicular fistula following primary trauma. Management modalities pursued include conservative approach for minimal symptoms, and dacryocystorhinostomy, dacryocystectomy, and lacrimal gland botulinum toxin injection. The mean follow-up period was 30 months (range: 3-months-6 years). CONCLUSION: PTCF is a complex lacrimal condition and the management of the PTCF needs a tailored approach guided by its nature and location and patient symptomatology.

An Intraosseous Pterygopalatine Fossa Dural Arteriovenous Fistula.

Intraosseous dural arteriovenous fistulas (DAVFs) are distinct in that the fistula is located within the bone rather than the dura through which the dural vessels pass. It has been stated that only fistulas within marrow should be considered as intraosseous DAVFs rather than DAVFs with traditional angioarchitecture that erode into bone or are located within a bony foramen. The ambiguity in the definition may have contributed to the oversight and scarcity of relevant cases reported in the literature. Three- or four-dimensional digital subtraction angiography is useful for determining the location of the fistula and developing treatment plans. We present an intraosseous DAVF around the pterygopalatine fossa using a transvenous approach.

Efficacy and Safety of Hyperbaric Oxygen Therapy in Fistulizing Crohn's Disease: A Systematic Review and Meta-analysis.

BACKGROUND: Hyperbaric oxygen therapy (HBOT) delivers 100% oxygen in a pressurized chamber, increasing tissue oxygen levels and regulating inflammatory pathways. Mounting evidence suggests that HBOT may be effective for inflammatory bowel disease. Our systematic review and meta-analysis aimed to quantify the efficacy and safety of HBOT in fistulizing Crohn's disease (CD). METHODS: A systematic review was conducted using the EMBASE, Web of Science, Pubmed, and Cochrane Library databases according to the "Preferred Reporting Items for Systematic Reviews and Meta-analyses" criteria. Study bias was assessed using the Cochrane Handbook guidelines. RESULTS: Sixteen studies with 164 patients were included in the analysis. For all fistula subtypes, the pooled overall clinical response was 87% (95% CI: 0.70-0.95, I2 = 0) and the pooled clinical remission was 59% (95% CI: 0.35-0.80, I2 = 0). The overall clinical response was 89%, 84%, and 29% for perianal, enterocutaneous, and rectovaginal fistulas, respectively. On meta-regression, hours in the chamber and the number of HBOT sessions were not found to correlate with clinical response. The pooled number of adverse events was low at 51.7 per 10,000 HBOT sessions for all fistula types (95% CI: 16.8-159.3, I2 = 0). The risk of bias was observed across all studies. CONCLUSION: HBOT is a safe and potentially effective treatment option for fistulizing CD. Randomized control trials are needed to substantiate the benefit of HBOT in fistulizing CD.

Late-Onset Chronic Corneal Fistula Following Phototherapeutic Keratectomy: A Case Report and Importance of Early Detection.

BACKGROUND We report a case of late-onset chronic fistula in a decompensated cornea after multiple ocular surgeries and a recent phototherapeutic keratectomy (PTK). CASE REPORT A 73-year-old woman presented to our service with a past ocular history of bilateral chronic angle closure glaucoma and pseudophakic bullous keratopathy in the left eye. Given a history of long-term uncontrolled glaucoma with advanced disc cupping and poor visual potential, the patient underwent multiple palliative procedures, including, most recently, a PTK. Few years later she presented with a spontaneous late onset of slowly appearing corneal leak on fluorescein staining upon routine clinical examination. Corrected distance visual acuity was hand motion and intraocular pressure (IOP) was 40 mmHg in the affected eye. Serial anterior segment optical coherence tomography (AS-OCT) sections were obtained, which aided in understanding the current presentation and revealed distinctive multilayer corneal changes during the healing process. The patient was successfully managed with cyanoacrylate corneal gluing and ocular hypotensive medications, which halted the corneal leak. CONCLUSIONS We report a case of a rare finding of corneal fistula in an eye with multiple previous ocular surgeries, and provide an explanation of the possible etiopathogenesis. We also highlight the pivotal role of AS-OCT for evaluating such cases and stress the importance of early detection of similar subtle leaks in the setting of a formed anterior chamber, which can often be missed, carrying a risk of infection.

Intermediate-term oncological and functional outcomes of salvage cryotherapy for the management of prostate cancer recurrence after primary brachytherapy versus primary cryotherapy: A propensity score-matched analysis.

BACKGROUND: Salvage cryotherapy (SCT) is widely used to treat prostate cancer (PCa) recurrence after radiotherapy (RT). We studied the intermediate oncological and functional outcomes of patients who underwent SCT following cryotherapy (CRYO-SCT) recurrence and compare it to recurrence after brachytherapy (BT-SCT). METHODS: An IRB-approved retrospective cohort study utilizing patient data from the Cryo On-Line Data Registry and the Duke PCa database between 1992 and 2016. Biochemical recurrence (BCR) using Phoenix criteria was the primary endpoint assessed at 2- and 5-years post-SCT. Secondary endpoints assessed functional outcomes including urinary continence, erectile function, and recto-urethral fistula. Association between treatment and biochemical progression-free survival was assessed using inverse probability weighted (IPTW) Cox proportional hazards regression. The differences in the secondary functional outcomes were assessed by Pearson's χ2 test or Fisher's exact test, corrected for IPTW. RESULTS: A total of 194 patients met inclusion criteria. The BCR rate for BT-SCT and CRYO-SCT was 23 (20.4%) and 17 (21%) at 2 years and 30 (26.5%) and 22 (27.2%) at 5 years according to Phoenix criteria. There was no statistical difference in 2 years (hazard ratio [HR] 0.9; 95% confidence interval [CI], 0.5-1.7, p = 0.7) or 5-year BCR (HR: 0.86; 95% CI, 0.5-1.5, p = 0.6) between the groups. The functional outcomes like urinary continence (p = 0.4), erectile function (p = 0.1), and recto-urethral fistula (p = 0.3) were not statistically different. CONCLUSION: CRYO-SCT appears to be well tolerated, with comparable oncological and functional outcomes to patients failing primary BT. The findings also demonstrated that SCT can render a significant number of patients biochemically free of disease after initial CRYO with minimal morbidity. SCT is a viable treatment option to salvage local PCa recurrence following either BT or cryoablation failure.

Bithalamic infarction in a tentorial dural artero-venous fistula and thalamic dementia: a case report and systematic review.

PURPOSE: To report a case of bilateral thalamic infarction (BTI) presenting as progressive thalamic dementia due to a midline tentorial dAVF (TdAVF) and to provide a systematic review of the literature. METHODS: We performed a systematic literature review of previously reported cases of bi-thalamic signal changes due to dAVF considering population characteristics, clinical presentation, imaging findings, treatments, and outcomes. RESULTS: We found 29 papers from 1985 until 2021 describing 35 cases of BTI dAVF-related. We analysed 36 cases comprehensive of our case report. The mean age was 58.7 years (range 38-79), 91.6% were males (n=33). Most cases presented with a subacute syndrome. In 86.1% (n=31) of cases a TdAVF was found; 58.3% (n=21) were type 2 Borden-Shucart fistulas, the remaining were mostly type 3. In 80.5% (n=29), a thrombosed sinus was identified. 33.3% of cases (n=12) had bi-thalamic haemorrhages. Endovascular treatment was performed in 83.3% of cases (n=30). A total of 75% (n=27) of cases had a good recovery. CONCLUSIONS: BTIs due to dAVFs may present with subacute symptoms overlapping with several differential diagnoses. Prompt identification at MRI, before venous drainage failure and bleeding, is crucial for a good prognosis.

Fistuloclisis: una herramienta útil en pacientes con falla intestinal / Fistuloclysis — A useful tool in patients with intestinal failure

Introducción: la fistuloclisis es una técnica descrita por Teubner y cols. donde se utiliza una fístula como vía de administración nutricional. Este procedimiento es una alternativa al manejo de los pacientes con fallo intestinal que reciben soporte nutricional por vía parenteral. Casos clínicos: presentamos dos casos clínicos de pacientes con antecedentes médicos distintos pero que coincidían en cuanto a cuadro de desnutrición, sepsis abdominal con fistulas y espera de reconexión intestinal. En ambos casos se administró apoyo nutricional con nutrición parenteral y nutrición enteral a través de fistuloclisis. Discusión: la nutrición enteral a través de fistuloclisis mejora la función de la barrera intestinal, reduce la tasa de infección intrahospitalaria en los pacientes críticos, mejora la función inmunológica, evita la atrofia de la mucosa intestinal y es por ello que tan pronto podamos localizar un acceso enteral deberemos aprovechar esta vía para que nuestros pacientes puedan experimentar los beneficios de la fistuloclisis, independientemente del aporte calórico administrado. (AU)

Introduction: fistuloclysis is a technique described by Teubner et al. whereby a fistula is used as a route of nutritional administration. This procedure is an alternative to the management of patients with intestinal failure receiving parenteral nutritional support. Case reports: we present two clinical cases of patients with different medical histories but who coincided in malnutrition, abdominal sepsis with fistulas, and their awaiting intestinal reconnection. In both cases nutritional support was administered with parenteral nutrition and enteral nutrition through fistuloclysis. Discussion: enteral nutrition through fistuloclysis improves function of the intestinal barrier, reduces the rate of intrahospital infection in critically ill patients, improves immune function, prevents atrophy of the intestinal mucosa, and that is why as soon as an enteral access is located we must take advantage of this route so that our patients may experience the benefits of fistuloclysis regardless of caloric intake.

Transvenous embolization of cerebrospinal fluid-venous fistulas: Independent validation and feasibility of upper-extremity approach and using dual-microcatheter and balloon pressure cooker technique.

BACKGROUND: Transvenous embolization is emerging as a promising treatment for cerebrospinal fluid-venous fistulas (CVF) associated with spontaneous intracranial hypotension (SIH). OBJECTIVE: To perform an independent validation of the efficacy and safety of the procedure and describe the procedural techniques used at our institution. METHODS: A retrospective review was performed including consecutive patients with SIH who had undergone CVF embolization with 3-month clinical and imaging follow-up. Clinical evaluation included the Patient Global Impression of Change (PGIC) Scale and six-item Headache Impact Test (HIT-6). Bern SIH score was used for imaging evaluation on brain MRI. Post-treatment changes in scores were assessed by Wilcoxon signed rank test. Procedural technical details, including use of upper-extremity access and dual-microcatheter pressure cooker technique, were recorded. RESULTS: 18 patients (13 female, median age 60 years) were included. 17 (94%) procedures were performed with upper-extremity access and 12 (67%) using dual-microcatheter pressure cooker technique. After embolization, 16 (89%) patients reported much or very much improved at follow-up PGIC; median (IQR) HIT-6 score improved from 68 (62-72) to 36 (36-38) and Bern SIH score improved from 8 (6-8) to 3 (1.5-3.5), p values <0.001. Side effects were transient embolization site back pain in 15 (83%) and rebound intracranial hypertension requiring medical management in 9 (50%) patients. HIT-6 and Bern SIH score changes were similar between conventional and pressure cooker techniques (p values >0.05). CONCLUSION: Transvenous embolization is independently validated as a highly effective and safe treatment for CVF and is feasible using upper-extremity venous access. Dual-microcatheter and balloon/coil pressure cooker techniques may be used to optimize distribution of embolic material and potentially, treatment efficacy.

Complex Gynecologic Fistulas Presenting 10 Years After Uterine Artery Embolization.

BACKGROUND: Uterine artery embolization (UAE) is a minimally invasive procedure for treatment of symptomatic uterine leiomyomas, but long-term complications are under-reported. CASE: This is the case of a healthy 51-year-old woman who had previously undergone UAE for symptomatic uterine leiomyomas. The patient presented with gross hematuria and pelvic pain 10 years later. She was found to have both a vesicouterine and a uteroduodenal fistula. The patient was successfully treated with hysterectomy, excision of the vesicouterine fistula, partial cystectomy, excision of the duodenal fistula, and primary duodenal repair. CONCLUSION: Complex gynecologic fistulas may occur as a long-term complication in symptomatic women with a history of UAE.

[Perilymphatic fistula in inner ear treated with blood patch].

Perilymphatic fistula (PLF) is a rare condition with a pathological communication between the inner ear and usually the middle ear, causing both cochlear and vestibular symptoms. PLF is typically treated with either a conservative approach or surgically with grafting. But a new treatment has been proposed: intratympanic injection of autologous blood, blood patch. This is a case report of a 21-year-old woman who presented herself with PLF and was successfully treated with blood patch.

Carotid-cavernous fistula masquerading as thyroid associated orbitopathy: a diagnostic challenge.

Purpose: To report a case of indirect carotid-cavernous fistula (CCF) in a patient who presented as a case of thyroid-associated orbitopathy (TAO). Case presentation: A 60-year-old female, known case of hypothyroidism, presented with left-sided headache associated with pain, protrusion and redness of left eye, the examination revealing vision of 20/ 80, proptosis, chemosis and severe ophthalmoplegia. All routine investigations were normal, including thyroid hormone levels. MRI brain & orbits showed increase in bulk of all extraocular muscles with tendon sparing. In view of suspicion of TAO, she was initially misdiagnosed and treated with parenteral and oral steroids, which resulted in further worsening of vision. Optical coherence tomography macula of the left eye revealed acute central serous chorioretinopathy that compelled the stoppage of steroids. While reviewing the patient again, dilated cork-screw tortuous episcleral vessels were found in the left eye. Thus, advised Digital subtraction angiography, confirmed as a case of low-flow left Indirect CCF, managed with endovascular embolization therapy improved her ocular symptoms completely in three days. Conclusion: CCF may mimic TAO due to overlapping features. In-view of different treatment protocols for both, it is critically important to look for atypical features in thyroid eye disease and keep CCF as one of the differential diagnoses for accurate management. Abbreviations: CCF = carotid-cavernous fistula, ICA = internal carotid artery, ECA = external carotid artery, TAO = thyroid-associated ophthalmopathy, BCVA = best corrected visual acuity, MRI = magnetic resonance imaging, IVMP = intravenous methylprednisolone, OCT = Optical coherence tomography, CSCR = central serous chorioretinopathy, DSA = digital subtraction angiography, IOP = intraocular pressure, CT = computed tomography.

Solución de St Marks como alternativa al manejo de la hiponatremia en la fístula ileal / St Marks solution as an alternative to the management of hyponatremia in ileal fistula

Las fístulas, especialmente las de alto débito, frecuentemente precisan hidratación y reposición electrolítica agresiva, destacando las pérdidas de sodio como principal complicación hidroelectrolítica.Varón de 53 años intervenido en julio de 2017 y que en noviembre 2018 ingresó para reconstrucción del tránsito intestinal. Tras varias intervenciones quirúrgicas apareció una fístula pioestercoracea de alto débito a nivel de íleo. El manejo de la fístula fue conservador con nutrición parenteral total individualizada lográndose balance hidroelectrolítico óptimo. Posteriormente el paciente perdió tanto el acceso venoso central como los periféricos, siendo imposible la canalización de una vía periférica en varios días. Durante este periodo el paciente desarrolló una hiponatremia severa que desde el servicio de Farmacia fue abordada por la vía oral con una solución de hidratación específica, como la solución de St Marks, que se caracteriza por su alto contenido en sodio y bajo en potasio para evitar hiperpotasemias que pueden dar lugar en estos pacientes. Con el tratamiento instaurado se logró recuperar las cifras de natremia evitando complicaciones neurológicas hasta que finalmente se canalizó una vía periférica. En nuestro paciente esta solución resultó ser efectiva logrando remontar drásticamente las cifras de natremia cercana a valores normales. Así pues, la solución de St Marks puede ser una alternativa a la vía intravenosa cuando no esté disponible o ser incluso complementaria a ésta. (AU)

Fistulas, especially those with high output, frequently require hydration and aggressive electrolyte replacement, highlighting sodium losses as the main hydroelectrolytic complication.53-year-old man who underwent surgery in July 2017 and who was admitted in November 2018 for intestinal transit reconstruction. After several surgical interventions, a high-output piostercoraceous fistula appeared at the ileus level. Management of the fistula was conservative with individualized total parenteral nutrition, achieving optimal fluid and electrolyte balance. Subsequently, the patient lost both the central and peripheral venous access, being several days without vascular access. During this period, the patient developed severe hyponatremia that the Pharmacy service treated orally with a specific hydration solution, St Marks’s solution, which is characterized by its high sodium and low potassium content to avoid hyperkalemias that can give rise in these patients. With the established treatment, it was possible to recover the levels of natraemia avoiding neurological complications until finally peripheral venous catheterization was placed. In our patient, this solution turned out to be effective, managing to drastically raise the levels of natraemia close to normal values. Thus, the St Marks solution can be an alternative to the intravenous access when it is not available or even be complementary to it. (AU)

Integrating Client Tracker Tool Into Fistula Management: Experience From the Fistula Care Plus Project in the Democratic Republic of Congo, 2017 to 2019.

This study aimed to document the experience of integration and the contribution of the Client Tracker (CT) to female genital fistula (FGF) management and data quality in sites supported by the Fistula Care+ Project in the Democratic Republic of Congo (DRC), from 2017 to 2019. It was a parallel mixed methods study using routine quantitative data and qualitative data from in-depth interviews with the project staff. Quantitative findings indicated that CT forms were present in the medical records of 63% of patients; of these, 38% were completely filled out, and 29% were correctly filled out. Qualitative findings suggested that the level of use of CT in the management of FGF was associated with staff familiarity with the CT, staff understanding of concepts in the CT forms, and the CT-related additional workload. The CT has mainly contributed to improving data quality and reporting, quality of care, follow-up of fistula patients, and self-supervision of management activities. A possible simplification of the CT and/or harmonization of its content with existing routine forms, coupled with adequate continuous training of staff on record-keeping, would further contribute to maximizing CT effectiveness and sustainability.

Coronary artery-bronchial artery fistula imaging characteristics and its correlation with pulmonary disease severity.

Hemoptysis is a common clinical emergency, bronchial arterial embolization is considered to be an effective treatment. The presence of coronary artery-bronchial artery fistula (CBF) may lead to recurrence of hemoptysis after treatment. It is necessary to investigate the imaging characteristics of a CBF and its correlation with the severity of pulmonary disease. With the development of multi-detector computed tomography, our study used the 320-slice CT bronchial artery angiography technology to observe and visualize blood vessels. The image and clinical data of 2015 hemoptysis patients with 320-slice CT bronchial artery angiography were retrospectively reviewed from January 2015 to December 2019. The axial and three-dimensional CT images were analyzed. The incidence, anatomical characteristics of CBF and pulmonary disease severity score were evaluated. A total of 12 CBF vessels were detected in 11 patients. We found that the incidence of CBF in this group was 0.55% (11/2015). Mean CBF diameter was 1.9 mm (1.2-2.5 mm). The course of CBF usually was relatively fixed. The proportions of CBF originated from the left circumflex artery, right coronary artery, and left anterior descending artery were 75%, 16.7% and 8.3%, respectively. Preliminarily analysis of the correlation between the trend of CBF and the pulmonary diseases severity score showed that CBF was more likely to communicate with a bronchial artery on the side with a higher severity score. CBF may occur in patients with chronic pulmonary disease and hemoptysis, and its origin, course and trend are characteristic. Detailed and comprehensive computed tomography angiography image analysis is helpful to improve the clinical treatment of hemoptysis with CBF.

High-flow priapism: Highly selective embolization of a traumatic arterio-cavernosal fistula.

We report the case of a 14-year-old man who arrived at the emergency department affected by a high-flow priapism due to a traumatic left arterial-sinusoidal fistula. After clinical examination, a colour Doppler ultrasound of the penis was performed which showed a left arterial-sinusoidal fistula measuring 7×16×30mm, with high-speed and turbulent flow. The fistula was successfully treated by three highly selective endovascular embolizations and at the 20days follow-up, clinical examination resulted normal.

Treatment efficacy and safety of drug-eluting beads transarterial chemoembolization versus conventional transarterial chemoembolization in hepatocellular carcinoma patients with arterioportal fistula.

This study aimed to compare the treatment efficacy and tolerance between drug-eluting beads transarterial chemoembolization (DEB-TACE) and conventional transarterial chemoembolization (cTACE) in hepatocellular carcinoma (HCC) patients with arterioportal fistula (APF). A total of 44 HCC patients with APF scheduled for DEB-TACE (N = 24, as DEB-TACE group) or cTACE (N = 20, as cTACE group) were recruited. Treatment response, hepatic function, and adverse events were assessed or recorded. Besides, progression-free survival (PFS) and overall survival (OS) were calculated. Total treatment response was better in the DEB-TACE group compared with the cTACE group (P = .012). Meanwhile, the objective response rate (87.5% versus 60.0%) was higher (P = .013), while the disease control rate (95.8% versus 85.0%) was similar in the DEB-TACE group compared to the cTACE group (P = .213). Besides, PFS (mean value: 12.2 (95%CI: 9.9-14.6) months versus 7.8 (95%CI: 5.6-10.0) months) (P = .037), but not OS (mean value: 20.0 (95%CI: 18.1-21.9) months versus. 18.6 (95%CI: 15.4-21.8) months) (P = .341) was prolonged in DEB-TACE group compared with cTACE group. Regarding the safety, Child-Pugh stage, albumin level, and bilirubin level after treatment were all similar between the DEB-TACE group and cTACE group (all P > .05); moreover, no difference was found in the occurrence of adverse events during or after treatment between the two groups (all P > .05). Moreover, subsequent analyses found that embolic materials for APF (microspheres) in the DEB-TACE group did not affect the treatment efficacy (all P > .05). DEB-TACE promotes treatment response and PFS compared with cTACE and shows good safety in HCC patients with APF.
