本文报道了250例手术治疗的脑动静脉畸形（AVM），其中22例病变主要位于丘脑和尾状核。通过胼胝体后部进入侧脑室心房的标准化半球间入路用于手术切除这些AVM。18例患者经血管造影证实完全切除；其中4例为小计切除。这组患者中没有死亡病例。半数患者在术前和术后出现近期记忆障碍，但大多数这些障碍是暂时的。其他并发症包括：术后同义性偏盲6例，短暂性偏瘫3例，半感觉丧失2例，Parinaud综合征1例，术后2年复发性出血1例。所有22名患者都恢复了原来的工作，过上了独立的生活。这一经验的结果表明丘脑尾状核AVM可以通过切除有效地治疗。
A series of 250 surgically treated cerebral arteriovenous malformations (AVM's) is presented, in which 22 lesions were located primarily in the thalamus and caudate nucleus. A standardized interhemispheric approach through the posterior corpus callosum and into the atrium of the lateral ventricle was utilized for the surgical removal of these AVM's. Total removal was confirmed by angiography in 18 patients; removal was subtotal in four cases. There were no deaths in this group of patients. Disturbances of recent memory pre- and postoperatively were seen in half of the patients, but most of these deficits were temporary. Other complications included: postoperative homonymous hemianopsia (six cases), transient hemiparesis (three cases), hemisensory loss (two cases), Parinaud's syndrome (one case), and recurrent hemorrhage 2 years after surgery (one case). All 22 patients returned to their previous occupations and are leading independent lives. The results of this experience indicate that thalamocaudate AVM's can be effectively treated by resection.
