Group I animals (control) received balloon injuries only. Group II had the site of balloon injury supported by a properly sized, balloon-expandable Palmaz stent placed directly over the injury site. Group III animals received a Palmaz stent covered with PTFE graft. All animals underwent arteriography immediately after intervention and again prior to sacrifice and specimen harvest at 4 weeks. The specimens were examined grossly and histologically at the proximal, middle, and distal segments for NIH development.Results: Uncovered stents developed significantly more NIH (p < 0.0001) and greater luminal narrowing (p < 0.001) than the controls. PTFE-covered stents (group III) exhibited less NIH (p < 0.001) and luminal reduction (p < 0.01) than bare stents (group II) at the middle portion of the stent-graft, but the PTFE cover had no effect on NIH and lumen reduction at the proximal or distal ends of the prosthesis.Conclusions: PTFE-covered stents retarded NIH at 4 weeks, but only at the midportion of the devices; the covering did not prevent neointimal pannus ingrowth at the proximal and distal ends.","PeriodicalId":79443,"journal":{"name":"Journal of endovascular surgery : the official journal of the International Society for Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20774505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were eligible for this procedure if their infrarenal AAAs (with or without iliac artery involvement) were considered appropriate for surgical resection; however, renal or other visceral arterial stenoses, aneurysmal disease requiring surgical treatment, and/or aneurysms of the hypogastric arteries excluded patients from laparoscopic AAA resection.Results: Of 31 candidates for this procedure, 9 were excluded owing to high surgical risk. Twenty-two patients (16 males; age range 62 to 88 years) were deemed appropriate for the laparoscopic procedure. Maximum aneurysm diameter ranged from 4.0 to 8.0 cm. The operation was completed successfully in 20 (91%) patients. Two (9%) deaths in high-risk patients admitted early to the study occurred within 30 days of surgery. The only major complication was an injured ureter, for which a nephrectomy was performed. Comparison to a historical cohort of conventionally treated patients showed that the study group needed less ventilator support, had shorter intensive care and hospital stays, and resumed diet earlier despite relatively prolonged anesthesia and aortic clamping times.Conclusions: The laparoscopic approach to infrarenal AAAs appears feasible, with several potential advantages in low- and moderate-risk patients. Once the technique is optimized, randomized prospective studies will be needed to verify the apparent benefits demonstrated by these initial patients.","PeriodicalId":79443,"journal":{"name":"Journal of endovascular surgery : the official journal of the International Society for Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20775334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After complete deployment of the stent-graft, the intraoperative completion angiogram disclosed unexpected occlusion of the left renal artery. Intra-aortic adjustment of the bifurcated graft was possible with a crossover guidewire, which was pulled caudally. The method worked perfectly to restore blood flow to the left renal artery. The patient is well 16 months postoperatively without any evidence of endoleak or graft migration; the left renal artery remains open.Conclusions: A technique is demonstrated for intra-aortic repositioning of a bifurcated stentgraft to correct insufficient deployment.

An aortoenteric fistula was diagnosed. At operation, the endograft fabric was found to be ruptured in an area of suture disruption between the nitinol stents. Coincidentally, a pre-existing inflammatory process might have caused adhesions between the bowel and the aortic wall, predisposing to fistula formation. The patient recovered after placement of a conventional aortic graft.Conclusions: Suture disruption between the internal support stents is a recognized complication in the first-generation Stentor device.

METHODS The distances from the lower-most renal artery to the aortic bifurcation and from the aortic bifurcation to the common iliac artery (CIA) bifurcation were measured using both CTA and aortography in 108 patients with abdominal aortic aneurysms. RESULTS The level of agreement between CTA and aortography was high, with 69% of aortic and 76% of iliac measurements within 1 cm and > 90% within 2 cm of each other. Mean differences were -0.35 +/- 1.20 cm and 0.25 +/- 1.10 cm, respectively, for aortic and iliac lengths. Aortography overestimated renal artery to aortic bifurcation length in comparison to CTA (p = 0.003), particularly in patients with large aneurysms (> 6.5 cm) and lumen diameters > 4.5 cm (p < 0.0001). Measurements of CIA length were shorter by aortography than CTA (p = 0.02). CONCLUSIONS There is a high level of agreement between CTA and aortography in the measurement of aortoiliac length, but aortography overestimates renal artery to aortic bifurcation length in patients with large-diameter aneurysms and wide aneurysm lumens. CTA is sufficiently accurate in the majority of cases to be used as the sole basis for the construction of endovascular grafts.","PeriodicalId":79443,"journal":{"name":"Journal of endovascular surgery : the official journal of the International Society for Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1998-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67343549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
