[Suppurative Thrombophlebitis of the Posterior Neck Caused by Streptococcus constellatus: A Case Report and Literature Review].

We report a rare case of suppurative thrombophlebitis of the posterior neck caused by Streptococcus constellatus. A 69-year-old female patient was admitted to the hospital with neck pain and fever, which had persisted for 16 days prior to hospitalization. On day 1 (day of admission), blood cultures (later identifying S. constellatus) were performed, and ceftriaxone (CTRX) IV (2 g SID) was started. On day 3, suppurative thrombophlebitis of the posterior neck was diagnosed by CT scan. The antimicrobials were changed from CTRX to ampicillin/sulbactam IV (12 g QID) to guard against the possibility of complicated infection with Fusobacterium spp. or Prevotella spp. On day 17, a CT scan revealed that the thrombus remained. Therefore, oral edoxaban (30 mg SID) was started. On day 27, the patient was discharged after her medication was changed to oral amoxicillin/clavulanate (1500 mg/375 mg TID). On day 33, the amoxicillin/clavulanate was changed to oral cefaclor (1500 mg TID) and edoxaban was discontinued due to itching. On day 45, the course of cefaclor was completed. The patient went on to follow an uneventful course with no relapses or complications for two years since the conclusion of treatment. These results suggest that when a patient presents with persistent neck pain accompanied by fever, suppurative thrombophlebitis of the posterior neck should be considered. In antimicrobial therapy, the treatment could be switched from intravenous to oral. In addition, direct-acting oral anticoagulants may be an alternative to other forms of anticoagulants.

Utility of multislice computed tomography as a strategic tool for complex percutaneous coronary intervention.

OBJECTIVES: Multislice computed tomography (MSCT) has been currently utilized as a non-invasive diagnostic modality to detect coronary artery disease. We sought to investigate whether preprocedural lesion assessment by MSCT could offer strategic guidance in the setting of elective complex percutaneous coronary intervention (PCI). METHODS AND RESULTS: Twenty-six complex coronary artery lesions in 23 patients were evaluated using 16-row MSCT scanner and an off-line image analysis workstation prior to the PCI. Procedural strategies of PCI were planned based on the morphologic and geometric analysis of the target lesion and vessel. MSCT provided valuable strategic information, which was useful for subsequent PCI procedure. The three-dimensional computed tomography (CT) images allowed us to determine optimal working view angle that best demonstrated the target lesion with least foreshortening. Furthermore, the thin-slab maximum intensity projected CT images of the target lesion served as a preprocedural road map depicting the bends of complex luminal path, vessel geometry and occluded segment of the vessel. As results, procedural success was achieved in all cases with complex lesions including chronic total occlusion. CONCLUSIONS: Our preliminary results showed that preprocedural lesion and vessel assessment by MSCT provided important additive strategic information that led to successful complex PCI procedures.

Optimal fluoroscopic view selection for percutaneous coronary intervention by multislice computed tomography.

We present 2 cases of patients with stenotic and occlusive coronary lesions, which were detected by multislice computed tomography (MSCT) coronary angiography and treated with percutaneous coronary intervention (PCI) using CT-oriented optimal fluoroscopic views. Preprocedural MSCT allowed us to select the optimal fluoroscopic angle to visualize the target lesions, which provided least amount of foreshortening and minimal overlap of side branches during the PCI procedures. Given its three-dimensional nature, MSCT provides additional anatomical information in the evaluation of complex coronary lesions prior to PCI.
