ABSTRACT
OBJECTIVE: To evaluate the early outcomes of retrograde in situ branched stent grafting (RIBS) using the gutter balloon technique for complex aortic arch aneurysms (CAAs). METHODS: The RIBS technique is an in situ needle fenestration procedure during thoracic endovascular aortic repair with the reconstruction of cervical branches. The double RIBS (D-RIBS) for the reconstruction of the left common carotid artery and the brachiocephalic artery using the gutter balloon technique was performed in 30 high-risk patients. We describe the early clinical results of the D-RIBS technique for CAAs. Primary end points were technical success and 30-day mortality. Secondary end points were postoperative complications, rates of endoleaks, overall survival, aneurysm-related death, and reinterventions. RESULTS: The mean age was 77.1 ± 6.6 years, and the mean maximum minor-axis aneurysmal diameter was 65.9 ± 8.9 mm. Twenty-six patients underwent D-RIBS for elective arch aortic aneurysm, and four patients were for reintervention after zone 2 thoracic endovascular aortic repair failure. Stent graft puncture was performed 60 times from the common carotid arteries, and technical success was achieved in all cases (100%). Postoperative complications included cerebral infarction in two patients (6.7%) and recurrent nerve palsy in one patient (3.3%). The 30-day mortality was 0%. During the median follow-up period of 14 months (6-56 months), overall survival at 12 months was 92.3% without any aneurysm-related death. Type 1 b and type 2 endoleaks were observed in one each, and no reintervention was encountered. CONCLUSIONS: Early clinical outcomes of the D-RIBS for high-risk patients with CAAs are acceptable. The gutter balloon method enables safe and reliable fenestration. Further studies and dedicated devices are warranted.

PURPOSE: To evaluate the efficiency of using the Ginza forceps (DVx, Tokyo, Japan), which have a long shaft and strong grip, for superficial phlebectomy with the stab avulsion technique, during simultaneous endovenous laser ablation (EVLA) of the great saphenous vein (GSV). METHODS: The subjects were patients treated with EVLA performed by a single operator at one institution. All patients had a GSV diameter of 4-10 mm and an EVLA length of the GSV of >20 cm. We compared 59 limbs treated only with the Varady hook (Group A) with 46 limbs treated with the Ginza forceps (Group G). RESULTS: The mean operative times for Groups A and G were 55.4 ± 17.1 vs. 48.5 ± 13.5 min, respectively (P = 0.002), and the number of stab incisions was 5.9 ± 2.9 (1-13) vs. 3.5 ± 2.3 (1-11), respectively (P < 0.001). The rates of nerve injury and thrombophlebitis were 1.7 vs. 0 and 3.4 vs. 0%, respectively. CONCLUSIONS: Performing superficial phlebectomy with the Ginza forceps reduced the operation time and the number of stab wounds. These initial results suggest that using the Ginza forceps for the procedure is safe and efficient.

BACKGROUND: To evaluate the optimal treatment for juxtarenal abdominal aortic aneurysm (JAAA), we compared the outcomes of open surgical repair (OSR) with endovascular aortic repair (EVAR) using a variety of fenestrated and snorkel EVARs. METHODS: We evaluated overall survival, aneurysm-related death, reintervention, and renal impairment in 152 JAAAs retrospectively, excluding cases of aortic dissection and rupture. Cox models were used to assess survival and assessed postoperative dialysis rates following surgery. RESULTS: OSR and EVAR were performed in 81 and 71 patients, respectively. The mean age was significantly higher in the EVAR group (overall, 74.5 years; OSR, 71 years; and EVAR; 77 years). High preoperative serum creatinine levels, cerebrovascular disease, and chronic obstructive pulmonary disease were more prevalent in the EVAR group. Mean operative time, hospital stay, and perioperative blood loss were significantly greater in the OSR group (P < 0.001 for all). The overall 30-day mortality was 1.9% with no statistical difference between 2 groups. The reintervention rate was significantly higher in the EVAR group (P = 0.01). Overall survival rates at 1, 3, 5, and 7 years were 97.4%, 91.6%, 86.3%, and 82.9%, respectively, with no significant difference between groups. Mortality in EVAR was associated with over 3.0 mg/dL of postoperative creatinine, and postoperative dialysis following OSR was associated with operative time and volume of bleeding. CONCLUSIONS: Acceptable outcomes were observed with OSR and EVAR. However, reintervention was more frequently required following EVAR. OSR appears to be the most appropriate first-line treatment for JAAA in good-risk patients; however, EVAR may represent an alternative option in high-risk patients.
