<b><i>Introduction:</i></b> The aim of this study was to investigate the technical success rate of obtaining 3D-safety margin in superselective conventional transarterial chemoembolization (cTACE) using 3D images for small hepatocellular carcinoma (HCC). <b><i>Methods:</i></b> Consecutive 48 HCC nodules (diameter, 1–3 cm) in 44 patients were intentionally treated by superselective cTACE in an attempt to achieve 3D-safety margin. Superselective CT during hepatic arteriography (CTHA) was obtained before cTACE. When negative 3D-safety margin was found, branches supplied into the margin area were detected by using a 3D workstation. The technical success rate to obtain 3D-safety margin was investigated by intend-to-treat analysis. Local tumor recurrence rate and adverse events were also evaluated. <b><i>Result:</i></b> Nine of 48 tumors (18.8%) had 3D-safety margin in the initial superselective CTHA. After pulling back of the catheter and/or selection of another branch based on 3D images, 3D-safety margin was finally achieved in 45 (93.8%). There were 8 of 46 tumors (17.4%) with local recurrence after 5-year follow-up. Grade 3–4 of aspartate aminotransferase, alanine aminotransferase, and total bilirubin were found in 38.6, 36.4, and 2.3%, respectively. One portal vein thrombus and 3 biliary dilation or biloma were developed. <b><i>Conclusion:</i></b> Superselective cTACE obtaining 3D-safety margin in small HCC was feasible with a high success rate by using 3D images, which could be tolerable and prevent local tumor recurrence.

Clinical Awareness

Spinal metastases are the most common of spinal neoplasms and occur predominantly in an extradural location. Their appearance in an intradural location is uncommon and is associated with a poor prognosis. Cerebrospinal fluid dissemination accounts for a significant number of intradural spinal metastases mostly manifesting as leptomeningeal carcinomatoses or drop metastases from intracranial tumors. The occurrence of local tumor dissemination intradurally following surgery for an extradural spinal metastasis has not been reported previously. The authors describe 2 cases in which local intradural and intramedullary tumor recurrences occurred following resection of extradural metastases that were complicated by unintended durotomy. To heighten clinical awareness of this unusual form of local tumor recurrence, the authors discuss the possible etiology and clinical consequences of this entity.

Abstract Background The purpose of this study was to assess the safety and efficacy of percutaneous transcatheter embolization (TCE) for the treatment of pulmonary arteriovenous malformations (PAVMs). Methods Forty-three consecutive patients (n = 17 males; n = 26 females) with 72 untreated PAVMs underwent coil and/or plug embolization between January 2010 and February 2018. The mean patient age was 42 ± 14 years (range 19–71 years). The median size of the feeding artery was 7.9 ± 2.9 mm (range 3.5–14.0 mm). The arterial blood gas level and cardiac function of all patients were analysed. The technical success rate, recanalization rate, and complications were evaluated. Computed tomography angiography (CTA) examinations were scheduled for 12 months after treatment and every 2–4 years thereafter. Results Twenty-five PAVMs were treated with coils alone, twenty-one were treated with plugs alone, and twenty-six were treated with both coils and plugs. The technical success rate was 100%. There were no complications during operation. However, one patient (2.3%) had pulmonary thrombosis and embolism post-operation. The patients’ pre-operative and post-operative PaO2 and SaO2 levels were significantly different (p < 0.01). A comparison of the New York Heart Association (NYHA) grade before and after embolization in all patients showed a significant decrease in the post-operative grade (p < 0.01). The 72 PAVMs were divided into three groups (coils only group [n = 25], plugs only group [n = 21], and coils/plugs combined group [n = 26]). After 12 months of follow-up, there were seven reperfusion PAVMs in the coil group, seven reperfusion PAVMs in the plug group, and 1 reperfusion PAVM in the combined group. There were significant differences between the two groups and the combined group. Conclusion Percutaneous TCE is safe and effective for the treatment of PAVMs. A combination of coils and vascular plugs may be useful for preventing recanalization after the embolization of PAVMs.

Abstract Background The aim of this study is to evaluate the efficacy and safety of a modified percutaneous radiologic gastrostomy (MPRG) technique under ultrasound and fluoroscopic guidance without endoscopic or nasogastric access. Results The study included 24 patients: 10 males and 14 females whose ages ranged from 44 to 80 years old. Ten patients had esophageal cancer and 14 patients had neck cancer. Technical success was achieved in 23 out of the 25 procedures (92%). Two procedures failed (8%) and were converted to the conventional technique by using the nasogastric tube. No major complications were reported. Minor complications were observed in 5 patients (20%): intraperitoneal air and contrast leakage in 4 patients and focal mucosal dissection by the contrast in 1 patient. Conclusion The MPRG has high technical success rate, is safe with no major complications, and is most feasible when endoscopic or nasogastric access cannot be performed.

Lower Morbidity

The endovascular treatment of renal artery aneurysms (RAAs) has lower morbidity and shorter stay lengths compared to surgical repair. Here, we describe coil packing with or without remodeling and assess outcomes and complications. We retrospectively identified the 19 consecutive preventive endovascular RAA coil embolizations done in 18 patients at our center in 2010–2020. Patient and aneurysm characteristics, technical success rate, complications, and recurrences were recorded. Mean patient age was 63 ± 13 years. The RAA was >1.5 cm in 11 cases, and in four cases, the aneurysm-to-parent artery size ratio was >2. Simple coiling was performed for 11 (57.9%) aneurysms, stent-assisted coiling for seven (36.8%) aneurysms, and balloon-assisted coiling for one (5.3%) aneurysm. Technical success rate was 100%. Complete definitive RAA exclusion was achieved with a single procedure for 17 (89.5%) aneurysms, whereas two (10.5%) aneurysms required a repeat procedure. Four minor complications occurred but resolved with no long-term consequences. No major complications occurred during the mean follow-up of 41.1 ± 29.7 months. Coil embolization by sac packing or remodeling proved very safe and effective. Together with the known lower morbidity and shorter stay length compared to open surgery, these data indicate that this endovascular procedure should become the preventive treatment of choice for RAAs.

Abstract Background Strictures are a common complication for patients with inflammatory bowel disease. Endoscopic stricturotomy (ESt) is a novel procedure for treatment of these strictures. Methods A chart review was performed for patients with strictures who underwent ESt. Results Eleven patients were included in the study and the total number of strictures treated was 12. The mean length of the strictures was 10.25 ± 4.36 mm. Technical success was achieved in 92% (n = 11) of the procedures. Postprocedural bleeding occurred in 9% (n = 1) of patients, and none of the patients had complications of infection or perforation. Conclusions ESt is a safe technique with high technical success rate.

Transhepatic Drainage

Background Historically, surgical bilioenteric bypass was the only treatment option for extrahepatic bile duct obstruction, but with technological advancements, percutaneous transhepatic drainage (PTD) and endoscopic solutions were introduced as a less invasive alternative. Endoscopic methods may lead to a decreasing indication of PTD in the future, but today it is still the standard treatment method, especially in hilar obstructions. Methods In our retrospective data analysis, we assessed technical success rate, reintervention rate, morbidity, mortality, and the learning curve of patients treated with PTD over 12 years in a tertiary referral center. Results 599 patients were treated with 615 percutaneous interventions. 94.5% (566/599) technical success rate; 2.7% (16/599) reintervention rate were achieved. 111 minor and 22 major complications occurred including 1 case of death. In perihilar obstruction, cholangitis were significantly more frequent in cases where endoscopic retrograde cholangiopancreatography had also been performed prior to PTD compared to PTD alone, with 39 (18.2%) and 15 (10.5%) occurrences, respectively. Discussion The results and especially the excellent success rates demonstrate that PTD is safe and effective, and it is appropriate for first choice in the treatment algorithm of perihilar stenosis. Ultimately, we concluded that PTD should be performed in experienced centers to achieve low mortality, morbidity, and high success rates.

Abstract OBJECTIVE To evaluate findings for patients with carotid cavernous fistulae or dural arteriovenous fistulae (AVFs) who underwent transvenous embolization via different transvenous approaches. METHODS Retrospective analysis of data for 31 patients (age range, 17–81 yr; mean age, 59.3 yr) with carotid cavernous fistulae (n = 6) or dural AVFs (cavernous sinus [CS], n = 11; transverse/sigmoid sinus, n = 14) was performed. The AVFs were treated with coils via different transvenous approaches, in 56 procedures. Doppler ultrasonography and time-resolved, two-dimensional, magnetic resonance projection angiography were performed to confirm the treatment. The mean clinical follow-up period was 32.5 months. RESULTS A total of 34 transvenous procedures were performed for 17 AVFs of the CS. Eleven patients with AVFs of the CS (63%) were cured with respect to clinical symptoms, and six patients experienced improvement (37%). The approach via the internal jugular vein and inferior petrosal sinus (n = 15) was possible in 60% of cases, with complete occlusion of the fistula in 78% of cases. With the approach via the facial vein (n = 8), there was a 50% success rate. The superior ophthalmic vein approach (n = 5) was associated with a high rate of technical success (100%), with a rate of complete fistula occlusion of 80%. We encountered complications, with transient morbidity, in four cases (23.5%). For 14 dural AVFs of the transverse/sigmoid sinus, 22 transvenous procedures were performed; 12 patients were cured (85.7%) and 2 experienced improvement (14.3%). The technical success rate was 86%, with complete occlusion in 42% of cases. Minor complications occurred in six cases (42.9%) but did not lead to permanent morbidity. CONCLUSION Transvenous treatment of CS and transverse/sigmoid sinus AVFs can be effective if all transvenous approaches, including combined surgical/endovascular approaches, are considered.
