Abstract: BackgroundVenous obstructions are common in patients with transvenous cardiac implantable electronic devices, but they rarely cause immediate clinical problems. The main consequence of these lesions is the difficulty in obtaining venous access for additional leads implantation.ObjectivesWe aimed to assess the prevalence and predictor factors of venous lesions in patients referred to lead reoperations, and to define the role of preoperative venography in the planning of these procedures.MethodsFrom April 2013 t… Show more

“…Venous obstruction is a well-known complication after implantation of a permanent transvenous pacemaker. The incidence of venous obstruction reaches 30–45% with complete occlusion rates of 12% on average and 1–3% for symptomatic occlusion [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. In the current study, severe venous obstruction was identified in 19.94% (40.77% if moderate occlusion was included) whereas complete occlusion in 22.34% of patients.…”

“…There are numerous reports on the estimation of the real risk of the TLE [ 26 , 27 , 28 , 29 ] but none of them considered LRVSO as a predictor of procedure difficulties. Among twenty reports on LRVSO [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ], only three papers analyzed the occurrence of LRVSO before TLE [ 2 , 6 , 14 ], and only two considered the influence of LRVSO on procedure complexity providing at the same time conflicting results. Among 20 reports on LRVSO only two studies were carried out in populations over 200 patients [ 1 , 2 ], 10 in 100–150 participants [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ] and the remaining eight studies in populations consisting of 30–89 patients [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”

“…As mentioned above, in non-dialysis patients, the insertion of transvenous lead(s) might result in central vein stenosis [8,9]. Central vein stenosis (CVS) is asymptomatic in most patients, but this is not the case in the HD population.…”

“…Transvenous CIED lead presence is associated with central vein stenosis. The frequency of severe stenosis or ipsilateral occlusion varies from 11 to 36% [8][9][10]. Therefore, when creating permanent vascular access, a clinical scenario may be complicated by CIED presence on one side and the lack of suitable vessels for arteriovenous fistula on the contralateral arm.…”

“…A remoção de cabos-eletrodos de dispositivos cardíacos eletrônicos implantáveis (DCEI) é procedimento pouco frequente e sua realização exige longo treinamento profissional e infraestrutura adequada. [1][2][3][4][5] Embora as indicações estejam bem estabelecidas em diretrizes médicas, sua utilização varia de acordo com a expertise de cada centro, sendo usada quase que exclusivamente para o tratamento de processos infecciosos relacionados aos DCEIs nos serviços menos especializados e em maior escala em serviços com maior experiência. [2][3][4][5][6][7][8][9] Como a maioria dos dispositivos implantados utiliza o acesso venoso para o implante dos cabos-eletrodos, as técnicas transvenosas são as mais utilizadas.…”
