Correction to: Impact of Patient and Lesion Characteristics on Drug-Coated Balloon Angioplasty in the Femoropopliteal Artery: A Pooled Analysis of Four Randomized Controlled Multicenter Trials

In their recently published pooled analysis of four drug-coated balloon (DCB) studies, which focused on the impact of patient and lesion characteristics on LLL at 6 months (Albrecht T et al. Cardiovasc Intervent Radiol. 2018 Dec 11. https://doi.org/10.1007/s00270-018-2137-3), the authors reported slightly inaccurate 2-year mortality rates.



Bariatric Arterial Embolization for Overweight Patients: A New Exploration for Ideal Patients?


A Very Unlucky Intraoperative Event During a Chimney Technique for Juxtarenal Aneurysm Exclusion

Abstract

A two-vessel Ch-EVAR procedure was scheduled within the instructions for use of the devices. After deploying, it appeared that the long sheath inserted through an arm access was discovered to be trapped behind the aortic stentgraft barbs. Trying to remove the sheath, the graft was displaced upward and the procedure was converted for a three-vessel Ch-EVAR incorporating the superior mesenteric artery. Simultaneous ballooning of the target vessels and the stentgraft permitted to exert a strong pullback traction on the blocked sheath, allowing its removal. A segment of the sheath distal end was left trapped in the aortic stentgraft. At 12 months follow-up, the patient is free of any complications and there are no occlusions of the abdominal visceral branches or embolic events in peripheral arteries.

Monomelic Ischemic Neuropathy of the Tibial and Peroneal Nerve After Onyx Embolization of Vasa Nervorum Supplying a Surgically Excluded Popliteal Artery Aneurysm

Abstract

Ischemic neuropathy is an exceedingly rare complication after peripheral artery embolization. We report a case of ischemic damage to the tibial and peroneal nerve after embolization of the vasa nervorum that served as feeding collaterals to a surgically excluded popliteal artery aneurysm.



Stenting the Upper/Cervical Oesophagus with a Proximal Deployment Cervical Oesophageal Stent: Technique and Outcomes

Abstract

Introduction

Proximal oesophageal stent deployment continues to provide challenges due to the proximity of the upper oesophageal sphincter and the associated subsequent complications such as globus sensation and stent migration. Patients with cervical oesophageal cancer have previously had limited stenting options available to them with a paucity of the literature describing the radiological technique for successfully placing these high-risk stents. In this paper, we present our experience using the Taewoong Niti-S CERVICAL Oesophageal Stent.

Materials and Methods

We describe our method for stent deployment highlighting the importance of pre-procedural planning in ensuring an adequate proximal landing zone for the short proximal flare of the stent. Furthermore, we outline how we have adapted our placement technique to incorporate a routine pre-dilatation stage which has optimised retrieval of the proximal to distal deployment system.

Results

We have placed eight cervical oesophageal stents within our institution. Contrast swallows in all the patients following stent deployment have demonstrated free flow of contrast to the stomach with all patients reporting symptomatic relief and no foreign body/globus sensation. There has been one episode of stent migration but no incidence of oesophageal perforation or haemorrhage.

Discussion

Evolution of stenting technique and the properties of the stents themselves are improving accuracy of stent placement in relation to the important landmark of the upper oesophageal sphincter.

Conclusion

Stenting of cervical oesophageal malignancy has proved successful in our institution and provided symptom relief for a subset of palliative patients who were previously unable to benefit from oesophageal stenting.



The Truth on Paclitaxel and the Mysterious Ways of Data Interpretation?


Onyx Embolization for Occlusion of the Proximal Internal Iliac Artery During EVAR in Patients with Unsuitable Landing Zones in the Common Iliac Artery

Abstract

Background

Twenty percent of the patients with AAA have an aneurysm involving the common iliac arteries. Large common iliac diameter can be treated with an iliac branched device or extension of the stent graft to the external iliac artery with occlusion of the ipsilateral internal iliac artery (IIA) to prevent type 2 endoleaks. This study describes and evaluates a embolization technique using Onyx in conjunction with EVAR in aneurysms with poor landing zones in the common iliac arteries.

Methods

Patients with Onyx IIA embolization during EVAR, identified from the hospital operating code database, constitute the study population. Onyx embolization was performed by injection at the IIA origin. Peri- and postoperative complications were collected from the medical records. Thin-sliced CT scan was performed 1 month and 1 year after the procedure.

Results

Thirty-six patients with complex iliac anatomy and insufficient landing zones (without sealing possibility for standard stent grafts) were identified out of 243 consecutive EVAR treatments during a 13-year period. In seventeen patients (7%), the IIA was embolized with Onyx. Technical success was obtained in all 17 patients, without adverse event or procedural complication. No complication related to the embolization procedure was noted during follow-up.

Conclusions

During EVAR treatment of patients with aneurysm involving the common iliac artery, Onyx embolization of IIA is a feasible option without need of selective catheterization of the IIA orifice, potentially preserving important branches of the IIA and simplifying emergency procedures.



Transarterial Chemoembolisation of Colorectal Liver Metastases with Irinotecan-Loaded Beads: A Bi-institutional Analysis of 125 Treatments in 53 Patients

Abstract

Purpose

To retrospectively review outcomes in patients treated for colorectal liver metastases with DEBIRI.

Materials and Methods

A retrospective analysis of patients with CRLM treated with DEBIRI was performed between 2008 and 2017 between two tertiary centres. Outcome parameters were overall survival and hepatic progression-free survival, as well as safety. Subgroup analyses were performed to assess the impact on outcomes of hepatic tumour burden at time of treatment, the presence of extrahepatic disease, prior systemic chemotherapy and the prior administration of systemic irinotecan-containing chemotherapy.

Results

Fifty-three patients received 125 treatments with DEBIRI over the study period. Median age of patients was 71 (range 41–88). Patients previously received a median of 1 line of chemotherapy (range 1–5). Median number of DEBIRI treatments was 2 (range 1–6). The median survival from first treatment was 14.5 months (range 1–107). Median hepatic progression-free survival was 5 months (0–86.5 months). The presence of extrahepatic disease (seen in 45% of patients) correlated with lower OS. Prolonged OS was seen in patients who received previous ablation and systemic chemotherapy. Technical success rate was found to be 99%. Post-procedural complication rate was 6%.

Conclusion

Our findings add to the growing body of literature to support the safety profile of DEBIRI in the treatment of CRLM. Further studies will be necessary to help establish the optimum berth of DEBIRI in the treatment algorithm for colorectal liver metastases.
