Traumatic Bleeding

Purpose: To evaluate the efficacy, safety, and feasibility of transradial approach (TRA) for endovascular management of traumatic bleeding. Materials and Methods: A retrospective review was performed at a single level 1 trauma institution from August 2018 to July 2019. Patients presented to the interventional radiology department who were intended to be treating using TRA for the management of trauma-induced bleeding were selected. Demographics, indication for embolization, embolization site, preprocedural labs, hemodynamic stability, technical success, and complications were recorded. Results: Transradial approach was attempted in 29 (74.4%) of the 39 patients identified by operators who prefer TRA. Four patients received treatment using TRA on 2 separate occasions, for a total of 33 procedures completed with a technical success of 97% (32/33). Transradial approach was safely completed in 9 patients (27.3%) with preprocedural hemodynamically unstable status. For the 10 patients who received treatment via a transfemoral approach (TFA), traumatic disfiguration of the left upper extremity, preexisting arterial lines placed by the trauma team, and external iliac artery injuries requiring covered stent placement were the most common indications for TFA over TRA. There were no procedural or access site–related complications. Conclusion: Transradial approach for the endovascular management of bleeding in a trauma setting is safe and effective with a high technical success rate and no complications.

Purpose: Osteoid osteomas are benign and nonprogressive lesions. The clinical presentation of osteoid osteoma is typical with night pain responsive to nonsteroidal anti-inflammatory agents. The typical radiological appearance is lucent nidus and adjacent reactive sclerosis. The most traditional management of osteoid osteoma is surgical removal which is associated with significant morbidity. This article aims to demonstrate our single-center experience of 55 patients with osteoid osteoma treated with percutaneous radiofrequency ablation (RFA). Methods: Fifty-five symptomatic patients who were seen at our orthopedics outpatient clinics, diagnosed with osteoid osteoma, and referred to interventional radiology department between May 2015 and April 2019 were enrolled. The nidus size, pain numeric rating scale score, and intramedullary edema diameter before and after RFA were compared. Clinical and technical success, intervention-related complications, and need for subsequent ablation were recorded. Results: Of the 55 patients, including 12 pediatric cases, 6 had atypical locations such as metatarsal, vertebra, and scapula, while 1 case had osteoid osteoma with multiple nidus. The mean age was 18.5 ± 9.6 years. Preintervention maximum nidus diameter, pain score, and edema diameter were significantly lower in postintervention measurements ( p < 0.001). Technical success rate was 98.1%, and clinical success was 96.36%. Severe complication occurred in one patient with soft tissue burn and osteomyelitis. Conclusion: This is one of the largest series of osteoid osteoma treated with RFA done in a single center with atypical cases. In conclusion, RFA is safe and effective in both pediatric and adult patients with rare complications even in challenging cases with atypical locations.

Superior Mesenteric Artery Dissection

Objectives The clinical outcomes, safety, and efficacy of endovascular management are explored for symptomatic isolated superior mesenteric artery dissection (ISMAD). Methods In this retrospective study, 51 consecutive patients with symptomatic ISMAD received endovascular management from three institutions between January 2011 and December 2019.These patients were categorized into group A (endovascular treatment was used as the first-line therapy) and group B(endovascular treatment was used as the second-line therapy). The general epidemiological data, clinical manifestations, first-episode symptoms, treatment process, imaging findings, follow-up outcomes were analyzed from the medical records. Results A total of 51 patients with endovascular management were collected in this study. Significant differences were observed between the two groups with respect to the course (150 h vs. 57 h; p < 0.001), intestinal ischemia (26.32% vs. 6,25%; p = 0.04) and dissection length (45.26 ± 13.78 mm vs. 63.37 ± 12.73 mm; p < 0.001). Technical success rate was 90.2% (46/51). There was significant difference in the MOD (42.27 ± 23.41 min vs. 76.63 ± 28.62 min p < 0.001), MPSRT (4.67 ± 2.65 h vs. 7.32 ± 2.49 h, p = 0.02), LOS (9.52 ± 3.72 days vs. 11.86 ± 4.13 days; p = 0.01) between the two groups. The bleeding complication rate was 7.84% (one patient in group A and three patients in group B). A total of 48 (94.12%, 48/51) patients were followed up for a median of 36.51 months (range, 4–87 months). Positive events of the SMA were achieved in 81.25% (39/48), and negative events of the SMA were achieved in 18.75% (8/48) based on the follow-up contrast-enhanced CT scan. Conclusions Endovascular management of symptomatic ISMAD has a high technical success rate and efficient at controlling symptoms. Furthermore, as more positive events occur, endovascular management should be encouraged early when pain persists after conservative management or there are signs of disease progression.

BackgroundThere is little consensus on endovascular treatment for symptomatic intracranial posterior circulation stenosis via the transradial approach (TRA). We report our multicenter experience and technical procedures that directly used a distal access catheter (DAC) via TRA for the treatment of symptomatic intracranial vertebral (VA) and basilar (BA) artery stenosis.MethodsFrom January 2019 to December 2020, 92 consecutive patients with severe symptomatic intracranial VA or BA stenosis were retrospectively collected and divided into two groups (TRA group and transfemoral approach (TFA) group) for neurointerventional treatment. The percentages of catheters reaching the V3/V4 segment of the VA and technical success, postoperative care conditions, preoperative outcomes and complications, long term clinical outcomes, and imaging follow-ups were observed.ResultsThe catheter, CAT 5, reached the V4 segment of the VA in 37 TRA patients (88.1%). The duration of the procedure was significantly shorter in the TRA group than in the TFA group (median 48.0 min vs 55.5 min, p=0.037). More patients in the TRA group could walk within 2 hours after the procedure (85.7% vs 10.0%, p=0.000), and the duration of retaining catheterization in the TRA group was shorter (3.0±1.2 hours vs 11.7±5.6 hours, p=0.000).ConclusionThis study demonstrates the potential feasibility and safety of using a DAC via the TRA without guiding support for the treatment of symptomatic intracranial VA and BA stenosis. The TRA demonstrated some advantages over the standard TFA in terms of patient comfort. Further randomized controlled trials comparing the TRA and TFA for posterior circulation stenosis are needed.

Purpose: To report the emergent endovascular management of an external iliac artery (EIA) rupture after standard guidewire recanalization and balloon angioplasty. Method and Results: A 54-year-old diabetic male presented with an occlusion of the EIA associated with severe stenotic lesions of the femoral bifurcation. Guidewire recanalization of the lumen was followed by balloon angioplasty, but evidence of EIA rupture was detected on the intraoperative arteriogram. Temporary homeostasis was achieved using the angioplasty balloon, and a Cragg EndoPro System 1 stent-graft was inserted transluminally to repair the injury. At 18 months poststenting, routine color Doppler confirmed continued patency of the vessel repair. Conclusions: While rupture of the EIA during angioplasty usually demands open surgical correction, an endovascular procedure can provide a fast, efficient, and less aggressive method of treating this serious complication.

Transradial Access

Purpose: To present a systematic review and meta-analysis comparing the transradial approach for aortoiliac and femoropopliteal interventions to the traditional transfemoral access. Methods: A search of the public domain databases MEDLINE, SCOPUS, Web of Science, and Cochrane Library Databases was performed to identify studies related to the use of the transradial approach for infra-aortic procedures. Meta-analysis was used to compare the transradial to the transfemoral route in terms of procedure success, complications, procedure parameters, and hospital length of stay. Results are presented as the odds ratio (OR) and 95% confidence interval (CI). Results: Nineteen studies containing 638 patients with transradial access for lower limb interventions were selected. Lesions were treated from the aortic bifurcation down to the popliteal artery. The mean technical success rate was 90.9%, conversion to a transfemoral approach was necessary in 9.9%, and complications were reported in 1.9%. The meta-analysis included 4 comparative studies involving 114 transradial and 208 transfemoral procedures. There was no significant advantage of either approach in terms of procedure success (OR 5.0, 95% CI 0.49 to 50.83, p=0.17), but the risk of developing a complication was significantly lower (OR 0.25, 95% CI 0.07 to 0.86, p=0.03) with the transradial approach. Conclusion: Transradial access for lower limb endovascular interventions can be performed with comparable technical success and a lower overall complication profile compared to transfemoral access.

Introduction Critical hand ischemia with advancing gangrene of digits requires urgent intervention to salvage as much tissue as possible. The purpose of this study was to evaluate the efficacy of “palmar arch loop” technique for endovascular management of critical hand ischemia by establishing inline flow to the palmar arch via both radial artery and ulnar artery, in patients with failed antegrade recanalization. To the best of our knowledge, this is the first case series evaluating the efficacy of “palmar arch loop” technique, with retrograde percutaneous transluminal angioplasty of the involved radial artery and/or ulnar artery. Material and methods We retrospectively investigated 10 patients (60% female; mean age 42 ± 18 years; mean time of presentation post-acute event 24 ± 11 days) with critical hand ischemia undergoing endovascular intervention using “palmar arch loop” technique at a single center in northern India between April 2017 and March 2019. All patients were followed up at regular intervals (weekly for a month, fortnightly for 3 months, and then at 6 and 12 months) with clinical assessment and SpO2 measurement. Study end points were technical success rate, hand healing, and primary patency rate at one year. Results Causes for critical hand ischemia were iatrogenic injuries due to inadvertent intra-arterial injection in 50% ( n = 5) and thromboembolic events in 50% patients ( n = 5). Vessels involved were: both radial artery and ulnar artery along with the PA in 50%; radial artery and palmar arch in 30%; ulnar artery and palmar arch in 20%. All of them had total occlusion of the involved vessel (>2/3rd of total length) with occlusion/diffuse disease of palmar arch as well; 70% technical success rate was achieved ensuring inflow to palmar arch via both the arteries with improved flow distally to the common and proper digital arteries. Retrograde percutaneous transluminal angioplasty of radial artery in 50% ( n = 5) and ulnar artery in 20% ( n = 2) was done successfully by looping the guidewire across the palmar arch; 90% showed subjective improvement in pain with healing of the lesions and/or formation of clear line of demarcation with reversal of pregangrenous changes proximally. Out of the eight patients with gangrene of fingers, three underwent minor amputation of the gangrenous digits and five underwent auto-amputation of the gangrenous tissue with complete healing of the stump. Primary patency rate was 85.7% at one year. There was no access site-related complication or mortality in the follow-up period. Conclusions Endovascular management of critical hand ischemia by “palmar arch loop” technique is an efficient technique to deal with occluded forearm vessels, particularly when antegrade recanalization fails. This technique, with good technical success and patency rates, is potentially a unique tool in the endovascular armamentarium for salvaging hand.

Abstract BACKGROUND: Carotid and vertebral artery dissections are a leading cause of stroke in young individuals. OBJECTIVE: To examine the published safety and efficacy of endovascular stenting for extracranial artery dissection. METHODS: We conducted a systematic review of the literature to identify all cases of endovascular management of extracranial carotid and vertebral artery dissections. RESULTS: For carotid dissections, our review yielded 31 published reports including 140 patients (153 vessels). Reported etiologies were traumatic (48%, n = 64), spontaneous (37%, n = 49), and iatrogenic (16%, n = 21). The technical success rate of stenting was 99%, and the procedural complication rate was 1.3%. Mean angiographic follow-up was 12.8 months (range, 2-72 months) and revealed in-stent stenosis or occlusion in 2% of patients. Mean clinical follow-up was 17.7 months (range, 1-72 months), and neurological events were seen in 1.4% of patients. For vertebral artery dissections, our review revealed 8 reports including 10 patients (12 vessels). Etiologies were traumatic (60%, n = 6), spontaneous (20%, n = 2), and iatrogenic (20%, n = 2). There was a 100% technical success rate. The mean angiographic follow-up period was 7.5 months (range, 2-12 months). No new neurological events were reported during a mean clinical follow-up period of 26.4 months (range, 3-55 months). CONCLUSION: Endovascular management of extracranial arterial dissection continues to evolve. Current experience shows that this treatment option is safe and technically feasible. Prospective randomized trials compared with medical management are needed to further elucidate the role of stenting.

Background: This retrospective study investigates the efficacy and safety of the novel Celt ACD® vascular closure device (VCD) following antegrade and retrograde common femoral artery (CFA) punctures for the treatment of peripheral artery disease in a challenging patient collective (e.g. calcifications, obesity, and anticoagulation). Methods: A total of 208 VCDs (i.e. 100 antegrade and 108 retrograde) were deployed between October 2019 and December 2020 in a tertiary referral interventional radiology department. Fifty-two devices were undersized in relation to the introducer sheath (up to 2 Fr). Technical success and VCD related complications were evaluated in the immediate post procedure period and the following 24 h clinically. In 68% of cases, additional duplex ultrasound was performed prior to discharge. Results: The overall technical success rate was 97%. Technical failures following antegrade approach were due to a too acute access angle (⩾60°), rendering it impossible to pass the applicator tip through the sheath lumen. A subgroup analysis of technical success pinpoints severe calcification as another key limiting factor in VCD use ( p = 0.004). Comparing equally sized with undersized device selection ( p = 0.196), direction of approach ( p = 0.265), and body mass index ( p = 0.184) proved to be insignificant. Five (2%, 5/208) major complications occurred: Four antegrade (i.e. one false aneurysm, one vessel laceration with retroperitoneal hemorrhage, two device migrations; 4%, 4/100) and one following retrograde access (i.e. >6 cm hematoma, 1%, 1/108)). Complications were successfully managed with manual compression or interventional procedures. Conclusions: The novel clip-based VCD proved to be effective with a low VCD related complication rate.

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 novel 180° cryoballoon (CbAS180) enables semicircumferential treatment over a length of 3 cm per application. This first-in-human study evaluates its feasibility, efficacy, and safety for the treatment of Barrett’s esophagus (BE) neoplasia. Methods This multicenter study consisted of dose-finding and extension phases. Dose-finding started with the lowest dose possible (1.0 mm/s). For each dose, six patients were treated circumferentially over a 3-cm length. The dose was increased until the median BE regression was ≥ 60 % without serious adverse events (SAEs). In the extension phase, the dose was confirmed in 19 new patients. The outcomes were technical success, BE regression after one treatment, and SAEs. Results 25 patients (median Prague C0M3) were included (6 dose-finding/19 extension). In two patients, the CbAS180 could not be applied because of unstable balloon positioning. The technical success rate was 96 % (22 /23). In the six dose-finding patients, the starting dose resulted in median BE regression of 94 % (95 % confidence interval [CI] 60 %–97 %) without SAEs and was thus considered effective. Overall median BE regression was 80 % (95 %CI 60 %–90 %). Conclusion Single-session CbAS180 seems feasible, safe, and effective, and is a promising technique for the treatment of patients with BE neoplasia.
