[Traumatic panhypopituitarism: case report].

We describe a case of traumatic panhypopituitarism following head injury. Generally considered, posttraumatic hypopituitarism occurs in patients who have suffered from severe head injury. However there were a few case reports of panhypopituitarism due to mild and moderate head injury. A 51-year-old male presented with a history of blunt head injury caused by a concrete block hitting his head directly during work. On admission, initial Glasgow Coma Scale was 14. Open depressed skull fracture was suspected. Emergency craniectomy and debridement were performed. Ten days after surgery, hypothermia, lethargy and appetite loss were manifested. Endocrinological examination showed panhypopituitarism with diabetes insipidus. MRI revealed ruptured pituitary stalk and pituitary gland hemorrhage. Coronal and sagittal MRI was helpful for the diagnosis of traumatic panhypopituitarism. General condition was recovered by hormone replacement therapy. It is important for medical staff carefully to observe vital signs and clinical symptoms, even if mild brain injury. Pituitary function test should also be undergone, if panhypopituitarism was suspected from clinical condition.

[Endovascular treatment for vertebral artery dissecting aneurysm: effectiveness of internal trapping with proximal flow arrest].

Ruptured vertebral artery (VA) dissecting aneurysms are associated with a higher incidence of rebleeding than saccular aneurysms, so, it is encouraged that diagnosis be followed by early treatment. The standard treatment for VA dissecting aneurysms is internal trapping using an endovascular technique. In this procedure, a proximal flow arrest is sometimes used to ensure safety. In this report, we demonstrated the usefulness of proximal flow arrest. The subjects consisted of seven patients treated with endovascular treatment for ruptured VA dissecting aneurysms from 1997 to 2005. Two of the seven patients were treated without proximal flow arrest and one of the two encountered rerupture of the aneurysm at coil embolization. Five patients were treated with proximal flow arrest. Internal trapping was safely completed in these patients. Overall outcomes measurment by Glasgow Outcome Scale were good recovery in three, moderate disability in one, vegetative state in one and dead in two. Proximal flow arrest is considered to be useful for the following four reasons: 1) for the prevention of distal embolism; 2) for the prevention of distal coil migration; and 3) to block blood flow upon rerupture; 4) for the balloon occlusion test, but the necessity of this technique is now controversial. However it is difficult to prove the necessity, we believe it is an effective optional technique for safety embolization.

Discrepancy between [18F]fluorodeoxyglucose and 11C-methionine positron emission tomography findings in Sturge-Weber syndrome--case report.

Cerebral blood flow and metabolism were evaluated in an adult with symptomatic intractable epilepsy and Sturge-Weber syndrome (SWS) manifesting as angiomas in the left cerebral hemisphere. 99mTc-ethylcysteinate dimer single photon emission computed tomography detected reduced blood flow in the entire left cerebral hemisphere, and [18F]fluorodeoxyglucose positron emission tomography (PET) showed decreased glucose metabolism in the left cerebral hemisphere. These findings indicated hypofunction of the left cerebral hemisphere, which caused the right hemiparesis. 11C-methionine (11C-Met) PET revealed high 11C-Met accumulation in the angiomas in the left cerebral hemisphere. Immunostaining for glial fibrillary acidic protein showed positive reaction in the lesions. Gliosis is a likely mechanism for the 11C-Met accumulation, which is possibly associated with progressive calcification in the angiomas and retarded growth of patients with SWS occurring over many years.

Percutaneous transluminal angioplasty and stent placement for subclavian steal syndrome with concomitant anterograde flow in the left internal mammary artery graft for coronary artery bypass--case report.

A 63-year-old man presented with subclavian steal syndrome associated with left internal mammary artery (IMA) bypass graft to a coronary artery. He was admitted with a history of oppressive sensation in the chest, dizziness, and light headedness on exertion for 2 weeks in March 2002. He had undergone myocardial revascularization consisting of a left IMA-to-left anterior descending coronary artery graft in April 1988. His blood pressure was 140/70 mmHg in the right arm and 80/64 mmHg in the left arm. Aortic arch arteriography revealed complete occlusion of the left subclavian artery proximal to the left IMA takeoff and subclavian steal with anterograde flow of the left IMA. Percutaneous angioplasty and stent placement with protection of the left IMA bypass graft using a balloon catheter was successfully performed without complication by cerebral or myocardial ischemia. Complete recanalization of the occluded left subclavian artery and anterograde flow of the left vertebral artery were achieved. His symptoms disappeared and blood pressure in the left arm recovered. This variant of coronary subclavian steal might require protection of the left IMA during angioplasty and stent placement.
