Anatomie şi tehnici chirurgicale <strong>Jurnalul</strong> <strong>de</strong> <strong>Chirurgie</strong>, Iaşi, 2011, Vol. 7, Nr. 3 [ISSN 1584 – 9341]<br />

Imposibilitatea i<strong>de</strong>ntificării nervului din partea dreaptă folosind criteriile<br />

menţionate mai sus atrage atenţia asupra unui eventual nerv nerecurent. Disecţia în<br />

imediata vecinătate a capsulei tiroidiene şi aplicarea ligaturilor numai pe elementele<br />

vasculare care intră în parenchimul tiroidian (inclusiv în cazul vaselor din pediculul<br />

tiroidian superior) previn lezarea nervului. Nervul nerecurent poate avea un traiect<br />

<strong>de</strong>scen<strong>de</strong>nt, în vecinătatea pediculului tiroidian superior, un traiect transversal sau chiar<br />

un traiect ascen<strong>de</strong>nt, în vecinătatea arterei tiroidiene inferioare.<br />

Toniato relatează un caz în care nervul laringeu inferior nerecurent era asociat cu<br />

o modificare a poziţiei vagului. Nervul vag (situat în mod obişnuit între artera carotidă<br />

internă şi vena jugulară internă) era la un pacient cu nerv laringeu inferior nerecurent cel<br />

mai medial element al mănunchiului vasculo-nervos cervical[5]. Nervul vag situat<br />

medial <strong>de</strong> artera carotidă internă ar putea <strong>de</strong>ci sugera existenţa unui nerv cu traiect<br />

nerecurent. Din păcate observaţia este singulară.<br />

Pentru o chirurgie sigură a glan<strong>de</strong>i tiroi<strong>de</strong> chirurgul trebuie să ţină seama <strong>de</strong><br />

reperele anatomice consacrate şi <strong>de</strong> existenţa variantelor anatomice.<br />
