Two cases treating aneurysms of the distal PICA were reported, and 36 cases with 39 aneurysms in the literatures in Japan were reviewed concerning the distribution of aneurysms and their findings on CT. Case 1; a 68-year-old female suffered from sudden onset of severe headache and nausea. On admission, it was found she was lethargic. However, her consciousness deteriorated down to semicoma with tetraparetic condition soon after. CT revealed subarachnoid hemorrhage in the basal, quadrigeminal and supravermian cisterns and blood clots in the entire ventricle. Cerebral angiography demonstrated an aneurysm located at the distal segment of the left PICA. She was initially treated conservatively because of being in Hunt and Kosnik Grade 5, and then, 3 weeks after onset, suboccipital craniectomy was performed and the aneurysm was clipped successfully. Case 2; a 60-year-old, female, suddenly experienced severe suboccipitalgia and vomiting. CT revealed subarachnoid hemorrhage in the entire subarachnoid space and intraventricular hemorrhages in the 4th, 3rd and lateral ventricles. Subsequently cerebral angiography was performed and left VAG demonstrated an aneurysm at the left A2-A3 junction. She underwent bifrontal craniotomy and the aneurysm was clipped via the interhemispheric approach. Her postoperative course was uneventful. Postoperative left CAG showed successful clipping of the aneurysm. However, left VAG suggested an aneurysm-like shadow in the right PICA. Right BAG carried out one week later demonstrated an aneurysm at the distal segment of the right PICA. This aneurysm was then clipped successfully under suboccipital craniectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

A successful case undergoing the ECA-PCA bypass operation with the use of an interposition saphenous venous graft for vertebrobasilar progressing stroke was reported and details of the operative techniques were described. A 40-year-old man was admitted because of confused mental state following sudden onset of headache, vomiting, vertigo, and ataxic gait. Neurological examinations revealed he was confused and restless, and left-sided Weber's syndrome, bulbar palsy and dysphasia were noticed. CT scan showed multiple small low density areas with no enhancement scattering in both occipital lobes and cerebellar hemispheres. Angiographical studies showed that the left vertebral artery was occluded at the vertebrobasilar junction and the right vertebral artery stenosed up to 90% or more at the branching site of the PICA. There was no visualization of the vertebrobasilar system through the right posterior communicating artery. The left posterior communicating artery was not examined. The patient was treated with Urokinase amounting to 740,000 units for ten days. Thirteen days later, however, he became progressively drowsy and he became unable to speak and swallow. Quadriparesis also appeared. Progressive deterioration of these brain stem ischemic symptoms was assumed to originate from critically lowered perfusion of the vertebrobasilar circulation. Therefore, the ECA-PCA anastomosis by means of a venous graft was carried out on the right side in expectation of the rapid restoration of the blood flow in the affected brain stem. A venous graft was chosen because it would carry larger amount of blood immediately after completing the bypass surgery than small calibered arterial graft such as a superficial temporal artery.(ABSTRACT TRUNCATED AT 250 WORDS)

We report the case of a 34-year-old man, treated by chiropractic manipulation for tension-type headache. The patient complained of a sharp occipital pain during the first session, followed by vomiting and loss of consciousness, and remained comatose for five days. Neurological examination detected persistence of dysarthria, ataxia, with delayed responses. Neuroradiological findings reveal an ischemic lesion in left PICA region, confirmed by angiography. Clinical and radiological findings suggested complete remission about two months later.

This is a case report of a patient with unruptured dissecting aneurysm in the vertebral artery that bled after being treated by proximal clipping. A 53-year-old male was admitted to our hospital due to transient right hemiparesis which occurred 20 days prior to his admission. He had been medicated for hypertension for the previous 33 years. CT scan and MRI showed lacunar infarction in the left corona radiata, and an aneurysm was accompanied with clot in the prepontine cistern. Angiography revealed a dissecting aneurysm in the right intracranial vertebral artery. His right hemiparesis was derived from infarction in the left corona radiata. It was likely that the dissecting aneurysm might rupture in the future. Proximal clip ping was performed to prevent rupture of the aneurysm. After clipping of the right vertebral artery distal to the PICA, the wall of the aneurysm appeared to be drawn toward the clip blades and to be tensed by the blades. Four hours after the operation, he complained of severe headache, and experienced a sudden loss of consciousness and the immediate development of a deep comatose state. CT scan disclosed massive SAH in the right cerebellopontine and basal cistern. Repeat angiography demonstrated that the aneurysm was not visualized and the right vertebral artery distal to the aneurysms was opacified through the left vertebral artery. Ventricular drainage was performed, but the patient died on the 20th day after bleeding. It was suspected that the aneurysmal clip might have produced shear force on the weak adventitia of the dissecting aneurysms and that the intra-aneurysmal pressure might have increased because of blood back-flow via the contralateral vertebral artery after the proximal clipping.

We studied clinical manifestations of sixteen patients with cerebellar infarcts diagnosed by MRI. In fourteen of them, the stroke developed abruptly with vertigo, which continued for several days. At the early stage of illness, ataxia was obscure. But after vertigo and nausea disappeared, nine cases showed truncal ataxia, while limb ataxia was found in only five. Their vertigo was rotatory and aggravated by head movement. Gaze-evoked nystagmus was observed in only 5 cases. Four patients preferred to take unilateral posture since they experienced less vertigo. The side of their lesions was the lower side of their posture. Limb ataxia was more frequent in SCA-involving cases than in SCA-non involving cases (3 out of 6 vs 2 out of 10, respectively). On the other hand, headache was more frequent in PICA-involving cases than in PICA-non-involving cases (6 out of 11 vs 1 out of 5, respectively). Ataxic gait was seen more in medial branch-involving cases than medial branch non-involving cases (5 out of 6 vs 4 out of 10, respectively). One patient died due to obstructive hydrocephalus.

We report a case of an anterior and posterior-inferior cerebellar artery (AICA-PICA) aneurysm. The patient was a 62-year-old woman who suffered from sudden onset of severe headache and nuchalgia. Computed tomography (CT) scan revealed subarachnoid hemorrhage in the ambient cistern and blood clots in the 3rd and 4th ventricles. Vertebral angiography demonstrated an aneurysm located at the distal segment of the left AICA-PICA. Three demensional CT scan was very useful for the decision concerning surgical strategy. The patient underwent bilateral occipital craniectomy and the aneurysm was clipped successfully via the midline suboccipital approach. Her postoperative course was uneventful. Postoperative angiography showed successful clipping of the aneurysm. Distal AICA-PICA aneurysm is a very rare disease and only one case has been reported in the literature. The clinical features, CT findings, and surgical approach of distal AICA-PICA aneurysms are briefly discussed while reviewing the literature.

We present a case of a spontaneous dissecting aneurysm at the vertebrobasilar artery including the right PICA in a 44-year-old man, who suffered from headache, hiccup and ataxic gait. The arteriograms showed an irregular narrowing and dilatation in the right PICA and in the vertebrobasilar artery, and showed fusiform dilatations in the bilateral middle cerebral arteries. We observed intramural hematoma and true lumen at the right PICA dissecting aneurysm on T1-weighted images on magnetic resonance imaging (1.5T, MRI), and the intimal flap was enhanced on T1-weighted image after intravenous injection of Gd-DTPA. The shape of the intramural hematoma showed a unique "two dumplings on a skewer" appearance, and the intensity of its hematoma in the false lumen decreased in gradient from adventitia to intimal flap on T1-weighted image on MRI. The dissecting aneurysm of the PICA was occluded spontaneously 1 month later, and it caused cerebellar infarction. However, the patient has been left only with the symptom of slight trunkal ataxia. Various shapes of intramural hematomas on MRI have been reported by Kitanaka in association with intracranial vertebrobasilar dissections. We suggest that "two dumplings on a skewer" shape which corresponds to the flow void of the true lumen, accompanied by intramural hematoma and enhanced intimal flap, on contrast-enhanced T1-weighted image, should be regarded as a true "diagnostic sign" of a dissecting aneurysm.

A case is reported of the vertebral arterial dissection presenting initially with cerebellar infarction, and which subsequently occurred with subarachnoid hemorrhage 14 days later. A 75-year old male was admitted because of vertigo and ataxia. MR T2-weighted imaging showed a hyperintensity areas on the left cerebellar hemisphere and MR angiography showed multiple stenotic lesions in the left vertebral artery. We diagnosed his illness as dissection of the left vertebral artery and antiplatelet therapy and the blood pressure control were carried out. Fourteen days after the onset, the patient complained of sudden onset of headache and subarachnoid hemorrhage was confirmed on CT scan. Proximal clip occlusion of the left vertebral artery and OA-PICA anastomosis was carried out immediately. The patient was discharged with slight truncal ataxia. We evaluated the features of this vertebral arterial dissection presenting with subarachnoid hemorrhage after ischemic stroke with reference to another reported cases.

Subarachnoid haemorrhage secondary to closed head injury is rarely associated with traumatic aneurysms of the posterior circulation. We report two cases of ruptured vertebral-posterior inferior cerebellar artery (VA-PICA) pseudoaneurysms following closed head injuries. In each case, there was no associated penetrating injury or skull fracture. The first patient was kicked followed by disturbed consciousness. The computerized tomography (CT) scan on admission and cerebral angiography on the 11th day after the trauma revealed a massive subarachnoid haemorrhage (SAH) with pan-ventricular haemorrhage and an aneurysm of the right PICA near its origin. Further ruptures occurred on the 12th, 15th, and 66th day, and he died on the 69th day. The second patient complained of persistent headache and nausea following a fight on the previous day. A CT scan and angiography on the 1st day after the trauma showed posterior fossa SAH with fourth ventricular blood and a tiny protrusion of the left VA-PICA. On the 14th day, repeated angiography revealed a remarkable growth of the aneurysm, followed by the second rupture. The repair of the VA-PICA junction was urgently performed with successful exclusion of the aneurysm. To our knowledge, only eight cases of traumatic aneurysms located at the VA or the PICA near its origin have been reported. When intraventricular blood is found with massive subarachnoid blood or with posterior fossa SAH, this ominous complication should be considered. Traumatic VA-PICA pseudoaneurysms are curable by refined microsurgical techniques, if diagnosed in time.

Anemia is a frequent extraintestinal manifestation of inflammatory bowel disease (IBD) that is commonly overlooked, despite its significant impact on quality of life. Characteristic symptoms include chronic fatigue, headache, and subtle impairment of cognitive function, although some less common symptoms include dyspnea, dizziness, pica, angular stomatitis, shortened attention span, and esophageal webs. Several types of anemia are associated with IBD, but iron deficiency anemia (IDA) accounts for the majority of cases and others include anemia of chronic disease, anemia associated with vitamin deficiency (vitamin B12 and folate), autoimmune anemia, and anemia caused by medication used to treat IBD. The diagnosis of IDA relies on laboratory blood tests. Therefore, these tests should be obtained on a regular basis because characteristic symptoms may be absent or not readily recognized by patients and their clinicians. Complete blood count may suffice; however, iron studies and serum vitamin levels may be necessary to differentiate between specific types of anemia. During the diagnostic process, it is important to consider coexistence of different types of anemia, especially if no response to therapy is noted. The therapy for anemia is directed towards treatment of the underlying inflammatory process and supplemental therapy, depending on the type of deficiency. Iron deficiency anemia is treated with iron preparations, first orally, and if unresponsive or if associated with untoward adverse events leading to decrease in adherence with the therapeutic regimen, with intravenous preparations. Intramuscular therapy has been abandoned due to high rate of complications. Intravenous therapy may be administered as a multiple-dose regimen (intravenous iron sucrose and gluconate) or as a single intravenous dose (iron dextran), which is associated with a higher risk of allergic infusion reactions and requires obligatory test dose administration. Treatment with erythropoietin is reserved for a select subgroup of patients with anemia of chronic disease. With appropriate treatment, the majority of patients with IBD will have significant improvement or resolution of anemia, which can lead to a better quality of life. However, a high index of suspicion should be maintained in order to identify the precise cause of anemia and to prescribe the appropriate therapy.
