We present three cases of heterotopic pancreas in the gallbladder wall. The patients (all female) presented with abdominal pain. Ultrasonography revealed polypoid tumor with coexistence of lithiasis in two cases. All patients underwent cholecystectomy. Microscopy revealed chronic cholecystitis and cholesteatosis and heterotopic pancreatic tissue. Heterotopic pancreas in the gallbladder wall is a rare heterotopia, with 23 cases reported in the international literature.
Arteriovenous fistulas (AVFs) consist of the preferable choice for patients needing hemodialysis. They have lower morbidity, mortality rates, and cost compared with grafts or catheters. Brachial vein transposition BVT-AVF is an alternative native option for creating an AVF. Brachial vein superficialization was first reported by Paul G. Koontz and Thomas S. Helling in 1983.1 The method was conceived for patients with chronic renal failure (CRF) lacking adequate superficial veins for fistulas, mostly for individuals who have already undergone a large number of access operations. Brachial vein transposition AVF can be performed as one-or two-stage procedure; both methods have advantages and disadvantages. We collected and reviewed all published data concerning transposition and superficialization of the brachial vein as an AbstractPurpose The purpose of the study was to investigate the patency rate of the brachial vein transposition-arteriovenous fistula [BVT-AVF] and to review the available literature regarding the comparison of the one-stage with the two-stage procedure. Methods A multiple electronic health database search was performed, aiming to identify studies on brachial vein superficialization. Case reports and series with five or less patients were excluded from the study. End points of the study were the patency rates at 12, 24, and 36 months of follow-up. The patency of the one-or two-stage BVT-AVF procedure was investigated. Results Overall, 380 BVT-AVFs were analyzed. The primary patency rate at 12 months ranged between 24 and 77%. Rate of early fistula malfunction or failure of maturation of the fistula resulting in loss of functionality ranged from 0 to 53%. Forearm edema, hematomas, wound infection, and early thrombosis were among the most common complications. Limited data were available for the comparison of patency rates between the one-and the two-stage procedure because of the absence of sufficient comparative studies. However, series with one-stage procedure presented a lower patency rate at 12 months compared to series with two stages. Conclusion Patency rates after BVT-AVF, although not excellent, has encouraging results taking into account that patients undergoing these procedures do not have an accessible superficial vein network; failure of maturation and the increased rate of early postoperative complications remain a concern. The BVT-AVF is a valuable option for creating an autologous vascular access in patients lacking adequate superficial veins.
Objectives: The non-penetrating Vascular Clip System (VCS) was tested experimentally and compared with the conventional suture method on the venous system. Materials and Methods: In five pigs, 30 transverse venotomies were carried out in the jugular and renal veins, and vena cava. Fifteen venotomies were reconstructed using autosuture clips and 15 using the standard needle and suture method. Eight weeks later, following phlebography, the specimens were examined macro- and microscopically. Results: For both methods, the veins remained patent; however, significant stenosis of 8.9% (95% CI: 0.6–17.1) for the renal vein and 8.5% (95% CI: 1.2–15.7) for the vena cava occurred when the suture technique was used. The intima to media height ratio remained the same. The anastomosis time with the clips was significantly shorter ( p<0.05), while the endothelium remained intact without any hyperplasia or inflammatory changes, which are usual findings of the suture technique. Conclusion: Early and mid-term results show that the VCS clipped anastomotic technique seems to be effective and acceptable for venous reconstructions.
We report the case of a single 46-year-old woman presenting with huge uterine fibroids growing for the last 12 years, resulting in a recent common iliac vein thrombosis. Due to the high risk for pulmonary embolism, an occluding balloon was inserted through the right jugular vein before the abdominal incision and occluded the vena cava just inferior to the renal veins. The tumor was easily mobilized, and the vena cava bifurcation was exposed and controlled until the uterus with the masses was resected. We recommend this method for oncovascular surgeries involving deep vein thrombosis and vein thromboembolism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
