Watershed area (medical)

Nokku Watershed, e kelme safaara, ko nokku ɓanndu, keɓoowo ƴiiƴam ɗiɗi ummoraade e caɗeele ɓurɗe woɗɗude e ƴiye ɗiɗi mawɗe. Yeru, ɓuuɓri ɓalndu mawndu ina heɓa ƴiiƴam ummoraade e caɗeele timmuɗe ƴiiƴam mesenterik toowɗam e ƴiiƴam lesɗam.

Helmere ndee ina firta e nate, ko ɓuuɓri ndiyam geologique, walla feccere ndiyam, seerndi ɓuuɓri ndiyam saraaji.

E sahaaji ɓuuɓgol gooto e ƴiye gonɗe e nokku ɗo ndiyam ɗam woni ɗoo, ko wayi no e nder ateroskleroosis, ɗeen diiwanuuji ina keɓa iskemi sabu ɓuuɓgol mum en ɗiɗmol. Kono tan, e sahaaji hipoperfusion systémique, ko wayi no coagulation intravasculaire disseminée walla insuffisance cardiaque, ɗeen nokkuuje ina teskaa e iskemi sabu ko ɗe caɗeele ɓurɗe woɗɗude e ƴiye mum en, ko ɗum waɗi ɗe ɓuri waasde heɓde ƴiiƴam keewɗam.

Nokkuuji ɓuuɓɗi ina tawee e ngaandi, ɗo nokkuuji ɗii ɓuuɓnata ƴiye ɓalndu yeesooje e hakkundeeje, e nder ɓalndu, ɗo nokkuuji ɓuuɓnata ƴiye mesenterik toowɗe e lesɗe (ɗum woni ɓuuɓri ɓalndu). Yanti heen, ƴiiƴam sigmoid e rektum ina mbaɗa nokku ɓuuɓɗo, tawa ina waɗi ƴiiƴam ummoraade e cirkulaasiyoŋ mesenterik les, pudendal e iliak. Hipoperfusion e nokkuuji ndiyam ina waawi addude ɓuuɓri mural e muus so tawii ko ñawu iskemiik ɓalndu. So tawii mboros oo ina waɗa e nder ngaandi, ina addana ɗum maale neurobiyoloji focal keertiiɗe, ballooje safrooɓe e ƴeewndo e nokkuuji. Yeru, nokku ɓuuɓɗo ɓalndu ina tawee e ɓalndu ɓalndu ; so tawii ko bannge nano, ɗum ina waawi addande ɗum afaasi mooftirgel transkortikal.
