ABSTRACT
External iliac artery (EIA) injuries caused by blunt trauma are rare. Here, we describe a blunt EIA injury after a motorbike accident suffered by a 16-year-old male. Despite conservative treatment, intermittent claudication persisted. He was successfully treated by elective endovascular stent-graft implantation on day 59 after the injury. Ankle-brachial index (ABI) improved, as did his symptoms. A contrast-enhanced computed tomography scan on postoperative day 90 showed no residual stenosis and favorable peripheral blood flow. This report suggests that elective endovascular stent-graft implantation might be a viable treatment option for blunt EIA injuries.

PURPOSE: To present long-term results obtained with endovascular abdominal aortic aneurysm (AAA) repair (EVAR) using the Zenith AAA endovascular graft from a single institution. MATERIALS AND METHODS: Between 2007 and 2013, 95 consecutive patients (median age 77 years) underwent EVAR using Zenith. Data were prospectively collected and retrospectively analyzed until 2019. Primary outcomes were overall survival, freedom from AAA rupture, and freedom from AAA-related death. Secondary outcomes were freedom from late (> 30 days) re-intervention and surgical conversion, and freedom from aneurysm sac growth (> 5 mm). RESULTS: The initial technical success rate was 96.8%. There were no deaths or intraoperative conversions. Overall survival at 1, 3, 5, and 10 years was 90.8%, 81.7%. 74.3%, and 57.2%, respectively. AAA rupture occurred in one patient (1.1%). Freedom from AAA-related death was 100% during the follow-up period. Freedom from aneurysm sac growth at 1, 3, 5, and 10 years was 98.8%, 86.4%, 76.9%, 53.0%, respectively. Freedom from late re-intervention and open surgical conversion at 1, 3, 5, and 10 years was 98.9%, 88.9%, 86.7, and 57.9%, respectively. CONCLUSION: EVAR with Zenith endografts represents a safe and durable means of AAA repair, and risk of rupture and aneurysm-related death are low.

PURPOSE: Inferior vena cava filter fracture (FF) may cause life-threatening complications, including cardiac tamponade, although the actual prevalence remains unclear. Therefore, we investigated the incidence of FF. MATERIALS AND METHODS: Data on fracture incidence with filter brands, filter positions [suprarenal (SR) vs. infrarenal (IR)], and follow-up durations were collected from the databases of eight hospitals. RESULTS: Of 532 patients, Günther Tulip (GT), Trap/OptEase (TE/OE), ALN and VenaTech (VT) were implanted in 345, 147, 38 and 2 patients, respectively. Of these, filter retrieval was attempted in 110 (21.7%) patients and was successful in 106 (96.4%). Of the remaining 426 patients, FFs were observed in two (0.7%) of 270 GT filters and 19 (14.1%) of 135 TE/OE filters. Fragment embolization occurred in one patient with a GT filter (50.0%) and three with a TE/OE filter (15.8%) with a total follow-up interval of 718.0 ± 1019.4 days. FF occurred more frequently in TE/OE than in GT filters (p < 0.001). Kaplan-Meier estimates showed significantly higher fracture-free rates for GT than TE/OE (p < 0.001) and IR-TE/OE than SR-TE/OE (p < 0.05). CONCLUSIONS: TE/OE filters are not suitable for permanent implantation due to the relatively early and high fracture rates.

Treatment for venous thromboembolic conditions differs significantly depending on whether the condition is acute or chronic. Endovenous treatment is now available for treating the most severe cases of acute massive pulmonary thromboembolism, and the goal is rapid central clot removal to relieve life-threatening pulmonary circulation. Endovenous catheter interventions include catheter-directed thrombolysis and catheter-assisted thrombus removal. The latter is divided into aspiration thrombectomy, fragmentation, and rheolytic thrombectomy. Data from cohort studies indicate that the clinical outcome and safety after open surgical treatment and endovenous treatment may be comparable. This paper reviews the current approaches to endovenous treatment for acute massive pulmonary thromboembolism, and presents our study of hybrid treatment using a combination of local fibrinolysis, mechanical fragmentation, and clot aspiration.
ABSTRACT
Intra-abdominal hemorrhage caused by omental artery rupture is a rare condition traditionally diagnosed via exploratory laparotomy in hemodynamically unstable patients. We experienced a case in which contrast-enhanced multidetector computed tomography (MDCT) and digital subtraction angiography did not identify the rupture site, whereas CT during left omental arteriography depicted a small 4-mm aneurysm. The lesion was then embolized with microcoils and N-butyl cyanoacrylate lipiodol glue. We consider that performing a CT during selective arteriography could be useful in cases in which the rupture site is unclear with other imaging techniques such as contrast-enhanced MDCT and digital subtraction angiography.
