Therefore, the LIT was removed under endoscopic observation during ileocecal resection surgery and the patient was treated conservatively.

Fenestrated and branched (cuff) grafts facilitate safe and durable repair, and bail-out maneuvers for target vessel cannulation and stenting have been established; however, the available bridging stent grafts have differences. The present article discusses the optimal selection of fenestrated or branched grafts, the cannulation of target vessels that have difficult anatomies, and the advantages and disadvantages of various bridging stents. We review the causes and risk factors of spinal cord injury (SCI), the protocol for prevention of SCI, and the outcomes of target vessel stent grafting, including patency and endoleak. Although conventional open surgery is the gold standard for the repair of thoracoabdominal aortic aneurysm (TAAA), it is highly invasive. To reduce invasiveness, hybrid surgery that combines open surgery and endovascular therapy has been developed [1, 2], and fenestrated and branched endovascular aneurysm repair (F/B-EVAR) is frequently performed at centers in the USA, Europe, and Japan [3-5]. Additionally, a hostile neck may be an independent factor for sac enlargement after EVAR for abdominal aortic aneurysm (AAA) [6], but a previous study reported that 41% of AAA cases presented with neck lengths outside the range prescribed by the traditional instruction for use [7]. Stark et al. showed that extending the graft above the highest renal artery would create an augmented neck length in 90% of patients with AAA [7]. F/B-EVAR is based on this principle. However, there are some technical tips for, and limitations of, fenestrated and/or branched graft. F/B-EVAR for TAAA and complex AAA will be reviewed in the present article.","PeriodicalId":73503,"journal":{"name":"Interventional radiology (Higashimatsuyama-shi (Japan)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47491044","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}

Material and Methods: CT fluoroscopy-guided biopsy was performed for 30 lesions (median long diameter 2.4 cm; range, 1.3-12.4 cm) in 30 patients (11 women and 19 men; median age 64.5 years; age range 37-90 years) using 18- and/or 20-gauge needles. The median length of the biopsy needle tracts was 9.3 cm (range, 5.5-13.0 cm). The median number of biopsy fires was 3 (range, 2-6). The median duration of the procedures was 33 min (range, 14-80 min). The diagnostic yield and adverse events (AEs) were retrospectively evaluated. The AEs were categorized using the Society of Interventional Radiology classification system. Technical success was determined by the acquisition of a sufficient number of specimens for pathological diagnosis. Diagnostic yield was defined as the match between the pathological and final diagnoses. Results: In all 30 procedures, CT fluoroscopy-guided biopsies of the abdominal para-aortic lesions were technically successful. Twenty-six lesions were malignant (9 malignant lymphomas and 17 lymph node [LN] metastases) and four were benign (one schwannoma, one granular cell tumor, and two normal LNs). One case was insufficiently diagnosed as a B-cell lymphoma; thus, the diagnostic yield of the biopsy was 96.7%. AEs occurred in seven procedures (23.3%), including six cases of class A hemorrhage and one case of class B vasovagal reaction. Conclusions: CT fluoroscopy-guided biopsy of abdominal para-aortic lesions is a safe procedure and provides a high diagnostic yield.","PeriodicalId":73503,"journal":{"name":"Interventional radiology (Higashimatsuyama-shi (Japan)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44907531","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}
