The present study evaluated the clinical and histopathological factors predicting AVF nonmaturation. Methodology: This prospective observational study was conducted over 18 months in 100 patients. AVF site venous tissue samples of 55 4/5 chronic kidney disease stages patients were collected. Histopathological analysis was done to detect four immunohistochemistry (IHC) markers, namely cluster of differentiation (CD68), CD31, α-SMA, and Ki67. IIntimal composition, hyperplasia, and calcification were also assessed. Fistulae were followed up at the 2nd, 6th, and 12th weeks and classified into mature and nonmature groups at 12 weeks based on clinical and Doppler examination. A comparison between the two groups was done and an association of radiological, histopathological, and IHC parameters of nonmature AVF was also carried out. Results: Among 55 patients, 35 (63.6%) had mature AVF and 26 (47%) had preexisting NIH. Preexisting NIH had no significant association with maturation (odds ratio: 0.44). Subjects without preexisting NIH had a significantly higher luminal diameter in 2nd week (P ≤ 0.05). There was a significant increase in blood flow both between the 2nd and 6th and between the 6th and 12th week (P < 0.05). Of the four IHC markers, three markers viz., CD68 (ρ = 0.525), CD31 (ρ = 0.420), and α-smooth muscle actin (ρ = 0.718) correlated significantly (P < 0.05) with the NIH. The mean AVF diameter and blood flow in the matured arm were more than that in the nonmatured arm at all the follow-ups (P < 0.09). Conclusion: The presence of CD68, CD31, and α-smooth muscle actin in the venous tissue suggests preexisting NIH which postoperative luminal diameter and blood flow may have long-term consequences in AVF functioning.","PeriodicalId":13375,"journal":{"name":"Indian Journal of Vascular and Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48666112","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}

Preoperative functional status is one of the key predictors of adverse outcomes in the postoperative period. This study investigated the role of 6-min walk test (6MWT) in predicting the outcomes after open surgery in abdominal aortic aneurysm (AAA). Methods: A prospective cohort study was conducted in patients scheduled to undergo open repair of AAA. The preoperative 6-min walk distance (6MWD) was calculated for patients, followed by postoperative monitoring of all patients who underwent surgery. Walking performance was classified with 300 m as a cutoff, and patients were divided into two groups with 6MWD- <300 m and >300 m. The results of 6MWT were analyzed with respect to cardiopulmonary complications, intensive care unit (ICU) stay, ventilatory or inotropic support, length of hospital stay, and mortality. Results: A total of 52 patients were included in the study, and 49 patients were able to complete the 6MWT. The patients with <300 m 6MWD had a longer stay in the ICU and an increased duration of ventilatory and inotropic support (P < 0.001). The <300-m group had an increased incidence of cardiopulmonary complications (47%, P = 0.001). The <300-m group had a higher duration of hospital stay (10.6 vs. 8.4 days; P = 0.01). All the patients who died in the perioperative period had a 6MWD <300 m (n = 3, P = 0.03). The 6MWD was the only strong predictor of adverse outcomes in the cohort. Conclusion: 6MWT can be safely performed in patients with AAA. A low walking distance correlates directly with increased perioperative morbidity and length of hospital stay. A distance of <300 m in patients with aortic aneurysm is predictive of perioperative morbidity and mortality.","PeriodicalId":13375,"journal":{"name":"Indian Journal of Vascular and Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46537961","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 with poor caliber veins distally on initial evaluation or with multiple fistula failures, basilic vein transposition is a good alternative. We present our experience with basilic vein transposition at our center. Methods: This study was a single-center observational study. A retrospective review of prospectively collected data from December 2013 to June 2019 was done. Qualitative variables were expressed as frequencies/percentages and compared between groups using the Chi-square test. Quantitative variables were expressed as mean ± standard deviation and compared between groups using unpaired t-test between groups and paired t-test within groups across follow-ups. Multiple linear regression analysis using a stepwise model selection tool was used to assess factors affecting the first cannulation. The best model was arrived in four steps where explanatory power (R2) increased from 66.6% to 79.3% (P < 0.001). Results: One hundred and eighty-eight patients formed a part of the study. One hundred and sixty-four patients underwent single stage, whereas 24 underwent two-stage transposition. Ninety-four each were male and female. The mean age was 51.38 ± 14.74 years. About 96.27% of fistulas underwent successful cannulation. The overall mean maturation time was 44.46 ± 7.21 days. It was 42.28 ± 3.71 for single and 60.27 ± 6.66 days for two-stage procedures. Primary patency at 6 months and 1 year were 92.82% and 85.67%, whereas primary-assisted patency rates were 94.6% and 91%. The secondary patency rate at 1 year was 60.77%. Salvage procedures included thrombolysis in 2, thrombectomy in 18, and thrombectomy with venoplasty in four cases. There were 28 failures. Fistula thrombosis was the most common cause. Complications included transient arm edema in 36.7%, late thrombosis in 7.7%, wound infection in 4.4%, and lymphorrhea in 6.9% of patients. Conclusion: The smallest basilic vein diameter for successful transposition is 2.5 mm. Factors used to predict successful maturation are initial vein diameter ≥2.5 mm, preoperative Peak systolic velocity (PSV) in brachial artery >70 cm/s, fistula flow rate of >400 ml/min at 6 weeks, and fistula diameter >4.5 mm at 06 weeks.","PeriodicalId":13375,"journal":{"name":"Indian Journal of Vascular and Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48768512","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}

Several variables, including population changes and comorbidities, have impacted patency rates. This study analyzes multiple parameters and estimates the patency rates and complications of brachioaxillary arteriovenous (AV) prosthetic grafts used for dialysis access in a single center. Materials and Methods: This was a prospective single-center study conducted at the Ramaiah Medical College Hospital in Bengaluru. This study comprised 92 patients with chronic renal failure who had brachioaxillary AV prosthetic graft surgery for dialysis access between 2018 and 2022. We monitored cases for up to 2 years for complications, and the primary and secondary graft patency rates were reported. Results: Seventy-five percent of the participants were male, with a mean age of 60. Diseases including hypertension (72.9% prevalence), diabetes (38.2%), and coronary artery disease (20.7% prevalence) were also very common. The present investigation found that thrombosis was the most frequent problem, followed by stenosis. In this study, the primary graft patency rates after 1 year and 2 years were 60.5% and 48%, respectively, whereas the secondary graft patency rates at 1 year and 2 years were 69% and 58%, respectively. Conclusion: The outcomes of this study regarding graft patency and complication rates compare favorably with other published data. Therefore, the authors consider brachioaxillary AV to be the optimal HD route when no acceptable forearm veins are available for creating AV fistulas.","PeriodicalId":13375,"journal":{"name":"Indian Journal of Vascular and Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45021645","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}

Sekar, Jithin Jagan, Rahul Sima, Rajan Archana","doi":"10.4103/ijves.ijves_1_23","DOIUrl":"https://doi.org/10.4103/ijves.ijves_1_23","url":null,"abstract":"Background: Infrapopliteal arterial disease is the most common finding in patients presenting with critical limb-threatening ischemia (CLTI) majority of whom also present with tissue loss. Vein bypass has been the gold standard of treatment in these patients. Nowadays, because of high peri-operative mortality and morbidity in these high-risk patients, endovascular treatment is offered first. Vascular restenosis, caused by intimal hyperplasia due to vessel injury during percutaneous transluminal angioplasty (PTA), remains the main limitation of infrapopliteal PTA and bare metal stent with clinical relapse and reinterventions. Drug-eluting stents (DES) are considered a possible solution to the problem of restenosis by reducing neointimal hyperplasia, after promising results in coronary arteries. Materials and Methods: Coronary DES was used as a bail out in patients undergoing below the knee (BTK) angioplasty. Those who developed dissection or recoil were stented with coronary stents. Multiple stents were used in patients with a long segment recoil of the artery. None of the stents were placed 2 or 3 cm beyond the origin of the tibial artery. The primary patency at 6 and 12 months, defined as absence of restenosis (≥50% stenosis) or occlusion based on clinical assessment and duplex scan, limb salvage and time taken to complete wound healing were assessed. Results: A total of 26 patients underwent drug-eluting stenting of the infra-popliteal vessels for CLTI during a period of 32 months. Technical success was possible in 92.3% patients (n = 24), however two patients had on table thrombosis of the stent. These two patients went on to have surgical bypass and their limbs could be salvaged. Wound healing was seen in 13 of 18 (72.2%) patients at 6 months and 11/12 (91.6%) patients at 1 year. Most patients took an average of 5 months to heal. Limb salvage was 11/12 (91.6%) at 1 year. Two patients underwent below-knee amputation for severe worsening sepsis due to uncontrollable foot infection. In both these patients' stents were patent at the time of amputation. Primary patency was 92.3% at 6 months and at 1 year. None of the patients required re-intervention. Mortality was 15.3% at 1 year. Conclusion: Off-label use of cardiac stents in the infra-popliteal segment seems a viable bailout option in patients undergoing revascularization. DES helps to achieve early technical success, longer patency, better wound healing, and improves limb salvage in these patients.","PeriodicalId":13375,"journal":{"name":"Indian Journal of Vascular and Endovascular Surgery","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41311281","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}
