面、颈部、四肢难治性血管瘤声像图

目的　分析面、颈部、四肢血管瘤的声像图特征 ,探讨难治性血管瘤的原因。方法　采用HP及ACUSON彩超仪对 2 1例术后病理诊断为难治性血管瘤的患者进行检查 ,其中 10例曾经多次治疗为复发性。结果　海绵状血管瘤 11例 ,呈中高及大小不等的蜂窝状低 无回声 ,含杂乱条索 ,挤压可变形。蔓状血管瘤 4例 ,表现为搏动性血管增粗 ,彩色缤纷多支迂回盘绕 ,扭曲穿越瘤体窜入各处 ,血量多且血流速度快。蔓状、海绵状混合性血管瘤 5例 ,表现为动脉与静脉的血窦、血池交错混杂。 1例血管瘤伴动静脉瘘。复发性血管瘤瘤区纤维瘢痕呈不规则条索或团块状 ,结扎的血管部分或全部重新开放。动脉血流是导致难治性及复发性血管瘤的主要原因。结论　血管瘤的二维声像图 (B超 )及彩色血流图 (彩超 )的特征明显 ,易确定其性质、大小、深度、血供及疗效 ,并可判断难治性病因

Ultrasonogram of refractory hemangioma over the face, neck and limbs

Objective To analyze the ultrasonographic characteristics of hemangioma over the face, neck and limbs and to appraise the cause of refractory hemangioma. Methods Twenty one patients with post operative pathologically diagnosed hemangioma were examined by HP and ACUSON color Doppler ultrasound, including 10 recurrent cases undergone several times of treatment.Results Moderate echoic zone combined with various sizes of honeycomb like hypoechoic or anechoic zone with bizarre stripes were shown in 11 patients with cavernous hemangioma which could be deformed under compression. Crooked colored flows were shown penetrating throughout the tumor with bulky volume and high speed blood flow. There were widening and pulsatile arteries in 4 with angioma arteriate racemosum, and mixed up of cisternae, sinus of arterioles and venules were shown in 5 with racemose mixed cavernous hemangioma. One case was accompanied by arteriovenous fistula. Irregular stripes or masses were shown as fibrous scars in the region of recurrence. The ligated blood vessels re opened partially or totally. The main cause of refractory and recurrent hemangioma was the presence of arterial blood flow.Conclusion The 2D and color Doppler characteristics of hemangioma are evident, by which the nature, size, depth, blood supply, curative effect and cause of refractory ones can easily be determined
