Este format\u0103 din confluen\u021ba a dou\u0103 vene mari: venele iliace comune dreapt\u0103 \u0219i st\u00e2ng\u0103, fiecare este format\u0103 in fuziunea venelor iliace interne \u0219i venelor iliace externe. Venele iliace sunt responsabile pentru colectarea s\u00e2ngelui din membrele inferioare, pelvis, organele genitale externe \u0219i peretele abdominal. S\u00e2ngele neoxigenat curge prin venele iliace interne de la organe \u0219i pere\u021bii bazinului, organele genitale, fese, spate \u0219i regiunile superioare ale \u0219oldului. La venele iliace externe, s\u00e2ngele neoxigenat curge prin membrele inferioare \u0219i peretele abdominal corespunz\u0103tor.<\/p>\n<p>Sindromul vena cava inferioar\u0103 (IVCS) este rezultatul obstruc\u021biei venei cave inferioare. Este cauzat\u0103 de invaziune, presiunea dintr-o structur\u0103 \u00eenconjur\u0103toare sau tumor\u0103 sau de tromboza din ven\u0103. Tromboza venei profunde face referire la formarea unui cheag de s\u00e2nge \u00een vena profund\u0103. Poate duce la simptome ca umflare \u0219i durere \u0219i complica\u021bii grave amenin\u021b\u0103toare pentru via\u021b\u0103, cum ar embolie pulmonar. Obstruc\u021bia IVCS poate s\u0103 apar\u0103 pe durata sarcinii \u0219i duce la complica\u021bii, cum ar fi frecven\u021b\u0103 cardiac\u0103 sc\u0103zut\u0103, sc\u0103derea func\u021biei renale \u0219i cre\u0219terea presiunii venoase. Simptomele asociate cu IVCS include edemul extremit\u0103\u021bile inferioare, tahicardie, \u0219i posibil sindrom hipotensiv supin. Pacien\u021bii pot avea simptome asimptomatice dup\u0103 ce au ap\u0103rut complica\u021biile.<\/p>\n<p>Tratamentul obstruc\u021biei IVCS depinde de cauza obstruc\u021biei, seriozitatea simptomelor, starea general\u0103 a pacientului, \u0219i propriile referin\u021be. Clasificarea cauzei poate ajuta doctorul \u00een diagnosticarea corect\u0103. \u00cen cazurile care implic\u0103 tromboza venei profunde, tratamentul medical poate include terapia anticoagulare, agen\u021bii trombolici, sau utilizarea unui filtru IVC, care cuprinde formarea cheagurilor de s\u00e2nge mari \u0219i le \u00eempiedic\u0103 s\u0103 mai c\u0103l\u0103toreasc\u0103 prin vena cava c\u0103tre inim\u0103 \u0219i pl\u0103m\u00e2ni.
