Clinical significance of ultrasound-assisted drawings in location of thyroid micronodule / 中华医学超声杂志（电子版）

ABSTRACT

Objective To explore the clinical significance of preoperative ultrasound-assisted drawings in location of thyroid micronodule resection .Methods A total of 88 patients ( 137 nodules ) who underwent thyroid micro-nodule resection were enrolled in the prospective randomized controlled study .All patients were randomly divided into two groups46 patients (68 micronodules) in experimental group and 42 patients (69 micronodules) in control group.Inclusion criteriathe maximum diameter of nodule≤1.0 cm. Preoperative thyroid ultrasound was conducted .Patients in experimental group also underwent ultrasound-assisted location of thyroid micronodule .Results The diagnostic accuracy rate of US was 81.82%(69/88) in all patients .With the help of ultrasound-assisted location , all nodules in experimental group were found quickly and accurately.The resection rate of experimental group was 100%(46/46).Whereas 4 nodules (in 4 patients ) were missed in control group with a resection rate of 90.5% (38/42).The postoperative US examinations after 3 months showed that all nodules were completely removed in experimental group while 4 nodules retained in control group .Conclusions Preoperative ultrasound-assisted drawings in location of thyroid micronodule plays an important role in thyroid nodule resection .It is great value of clinical application .
