Frontal bone defect with frontal sinus mucopyocele

For this patient's treatment, all three consultants advise against the Lynch-type frontoethmoidectomy procedure, with or without mucoperiosteal flap reconstruction of the nasofrontal duct. Treatment plan: Culture and sensitivity of pus; 2-3 weeks of intravenous antibiotics followed by osteoplastic flap fat obliteration of frontal sinus; delayed defect repair with methyl methacrylate (Montgomery). Trephination followed by treatment with local and systemic antibiotics (Donald); removal of infected bone and soft tissue (sinus collapse) and delayed defect repair in 6-12 months (Donald, Calcaterra) with metylmethacrylate (Donald) or in situ cured silicone elastomer (Calcaterra).     

Coronary sinus septal defect. Surgical considerations.

The coronary sinus septal defect is an uncommon anomaly. If it is not suspected, found, and repaired at operation, a residual intracardiac shunt will result. The defect usually is associated with a left superior vena cava (LSVC), which necessitates special consideration in the conduct of cardiopulmonary bypass. Our recent treatment of three cases of coronary sinus septal defect stimulated us to review the embryology, anatomy, diagnosis, and surgical treatment of this malformation.     

Coronary sinus septal defect associated with tricuspid atresia

Coronary sinus septal defects are unusual congenital anomalies that may assume particular clinical importance in patients undergoing a modified Fontan procedure. Two of 10 patients with tricuspid atresia who underwent a modified Fontan procedure between January, 1984, and December, 1984, were noted to have coronary sinus septal defects in the early postoperative period. A pathologic review of 159 specimens of tricuspid atresia revealed coronary sinus septal defects in four. Although infrequent, coronary sinus septal defects may permit significant persistent right-to-left interatrial shunting after a modified Fontan procedure. Ideally, preoperative recognition allows for selective direct closure or closure of the coronary sinus orifice. Alternatively, routine baffling of the coronary sinus into the left atrium obviates this potential source of interatrial communication.     

Coronary sinus atrial septal defect diagnosed by cyanosis after operation of ventricular septal defect

We have experienced a case of coronary sinus atrial septal defect (ASD) with ventricular septal defect (VSD). Cardiac catheterization revealed a step-up of oxygen saturation in right ventricle, L-R shunt 70.3%, R-L shunt 6.9% and pulmonary hypertension (PH). Since diagnosis of coronary sinus ASD was difficult, the operation was performed under diagnosis of VSD. Although the operation was success, cyanosis appeared after the operation. Contrast echocardiography using subcostal 4 chamber view showed coronary sinus ASD with a large Thebesian valve and the right-to-left shunt of the ASD. The Thebesian valve seemed to lead the venous return flow to the left atrium. Coronary sinus ASD was closed using a Xenomedica patch.     

Alternative technique for repair of sinus venosus atrial septal defect

A technique is described for closure of a sinus venosus atrial septal defect using a single patch held in place by sutures placed from outside the right atrium and underneath the superior vena cava. The superior vena cava does not require enlargement and potential damage to the artery to the sinoatrial node is avoided.     

Surgical repair of inferior sinus venosus atrial septal defect.

A 9-year-old girl presented for cardiac evaluation with symptoms of dyspena, fatigue, and cyanosis with exercise. Cardiac catheterization demonstrated an atrial septal defect; an anomalous right superior pulmonary vein was suspected but not confirmed. Operation disclosed anomalous drainage of the right superior and inferior pulmonary veins into the right atrium, an intact fossa ovalis, and an inferior sinus venosus defect. Repair was accomplished by detaching the posterior edge of the atrial septum and suturing it to the right of the pulmonary veins, so that the defect was closed and all the pulmonary venous blood was directed to the left atrium.     

中线位颅骨缺损伴额窦损伤的外科治疗

目的 探讨严重颅面外伤后中线位颅骨缺损伴额窦损伤的外科治疗方法.方法 对11例中线位颅骨缺损伴额窦损伤的患者行额窦刮治术,以游离颞肌筋膜封闭额窦顶部,10例患者同时行钛修复体植入修补颅骨缺损,1例行二期颅骨缺损修补.结果 9例患者植入钛修复体修复颅骨缺损后恢复良好,1例患者二期行颅骨缺损修补,术后恢复良好,1例患者因额窦炎感染取出颅骨缺损修复体,并行额窦鼻腔吻合手术.结论 对于颅骨缺损伴额窦损伤的患者,如无明显感染或轻度感染,可以一期刮除残留额窦黏膜,以游离颞肌筋膜封闭额窦顶部,同时行颅骨缺损修补;对于伴有严重感染的额窦残窦炎,需彻底刮除残留额窦黏膜,以游离颞肌筋膜封闭额窦顶部,二期再行颅骨缺损修补.     

无顶冠状静脉窦综合征合并房室通道的外科治疗

目的总结无顶冠状静脉窦综合征合并房室通道的手术经验，为术中处理此类疾患提供借鉴。方法2001年至2005年治疗8例无顶冠状静脉窦综合征合并房室通道病人，其中完全型房室通道2例，部分型房室通道6例，均合并中至重度肺动脉高压。均为永存左上腔静脉（PLSVC）直接汇入左房（LA），即完全型冠状窦间隔缺损（I型）。手术采用心外管道连结PLSVC至右心耳4例，心内隧道重建冠状窦顶3例，直接结扎PLSVC1例。结果全组无死亡，远期效果满意。结论房室通道合并PLSVC时，要警惕无顶冠状静脉窦综合征的存在。根据PLSVC汇入左房的位置选择不同的手术方法，可获得满意的手术效果。
