We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired. An agreement was reached to remove the shunt device and observe the patient for any neurological symptoms, and after the shunt was removed and the previous cranial opening filled with fibrin glue by Neurosurgery, we debrided the deteriorated flap and provided coverage with 2 large opposing rotational flaps. During 2 months' outpatient follow-up no neurological symptoms appeared, and the new scalp flap displayed slight depression but remained intact. The patient has declined from any further follow-up since.
我们报告一例游离皮瓣恶化病例,可能是由脑室腹腔分流术(VP分流术)上方颅骨缺损导致的压力梯度引起的。患者为78岁男性,因进行性脑积水接受了VP分流术。术后,VP分流术周围的头皮皮瓣塌陷并出现坏死迹象,部分分流导管外露。在用桡侧前臂游离皮瓣覆盖缺损后,游离皮瓣部位出现逐渐下沉的迹象,而皮瓣的血运未受影响。经协商决定移除分流装置并观察患者有无神经症状,在分流装置移除且神经外科用纤维蛋白胶填充先前的颅骨开口后,我们对恶化的皮瓣进行清创,并用两个大型对向旋转皮瓣覆盖。在2个月的门诊随访中未出现神经症状,新的头皮皮瓣有轻微凹陷但保持完整。此后患者拒绝进一步随访。
