The size of pelvic hematoma can be a predictive factor for angioembolization in hemodynamically unstable pelvic trauma

PURPOSE: Unstable pelvic fracture with bleeding can be fatal, with a mortality rate of up to 40%. Therefore, early detection and treatment are important in unstable pelvic trauma. We investigated the early predictive factors for possible embolization in patients with hemodynamically unstable pelvic trauma.METHODS: From January 2011 to December 2013, 46 patients with shock arrived at a single hospital within 24 hours after injury. Of them, 44 patients underwent CT scan after initial resuscitation, except for 2 who were dead on arrival. Nine patients with other organ injuries were excluded. Seventeen patients underwent embolization. A single radiologist measured the width (longest length in axial view) and length (longest length in coronal view) of pelvic hematoma on CT scans. Demographic, clinical, and radiological data were reviewed retrospectively.RESULTS: Among 35 patients with hemodynamically unstable pelvic fracture, 22 (62.9%) were men. Width (P = 0.002) and length (P = 0.006) of hematoma on CT scans were significantly different between the embolization and nonembolization groups. The predictors of embolization were width of pelvic hematoma (odds ratio [OR], 1.07; P = 0.028) and female sex (OR, 10.83; P = 0.031). The cutoff value was 3.35 cm. More embolization was performed (OR, 12.00; P = 0.003) and higher mortality was observed in patients with hematoma width >3.35 cm (OR, 4.96; P = 0.048).CONCLUSION: Patients with hemodynamically unstable pelvic trauma have a high mortality rate. CT is useful for the initial identification of the need for embolization among these patients. The width of pelvic hematoma can predict possible embolization in patients with unstable pelvic trauma.

Posterior Reversible Encephalopathy Syndrome in a Critically Ill Postoperative Patient / 대한중환자의학회지

Posterior reversible encephalopathy syndrome (PRES) is a transient condition characterized by altered mental status, seizure, headache, and visual disturbance with typical neuro-imaging findings in the bilateral parieto-occipital regions. Clinicians should be aware of this syndrome because delayed diagnosis and treatment result in irreversible neurologic deficits. We present the case of a 77-year-old male diagnosed with PRES in the setting of postoperative critical illness caused by small-bowel strangulation.

Inferior Vena Cava (IVC) Filter Retrieval Rates after Catheter Directed Thrombolysis or Pharmacomechanical Thrombectomy in Deep Vein Thrombosis (DVT) and Its Characteristics

PURPOSE: Inferior vena cava (IVC) filter is commonly practiced to prevent pulmonary embolism during endovascular therapy of deep vein thrombosis (EndoDVT). When the thrombus is trapped inside the filter during intervention, its removal is quite challenging. The purpose of this study is to determine retrieval rates of IVC filter after EndoDVT and its characteristics. METHODS: Patients who underwent EndoDVT in Inha Unversity Hospital from June 2004 to May 2009 were reviewed retrospectively. Retrievable IVC filter was inserted before EndoDVT. EndoDVT was done by catheter directed thrombolysis or pharmacomechanical thrombectomy using urokinase. IVC filter retrieval was decided according to computed tomography after 2 weeks. RESULTS: 126 patients were treated with EndoDVT. Optease (n=101) and Tulip (n=25) IVC filters were inserted. IVC filters were retrieved in 42.9% (54/126). There was no IVC filter related complication during its insertion and removal. IVC filter was not retrieved in 72 patients. Reasons for its failure include residual thrombosis in IVC filter (n=28), high risk for recurrent DVT (n=34), massive pulmonary embolism (n=8), and death (n=2). Residual thrombus inside IVC filter disappeared in 5 patients during 6-month follow up. CONCLUSION: IVC filters retrieval rate after EndoDVT was 42.9%. This can be improved by thorough patient follow up and extended retrievability.

Incidental Findings of Thyroid Detected by PET-CT during Cancer Follow-up / 대한내분비외과학회지

PURPOSE: The incidence of thyroid cancer is increasing in Korea, partially owing to the development of diagnostic tools. Positron emission tomography (PET)-computed tomography (CT), in particular, has generally been used for evaluation of metastasis and follow-up of malignancy. METHODS: We retrospectively investigated 2,833 patients with PET-CT for metastasis work-up or cancer follow-up, which was performed between January 1998 and May 2008 at Inha University Hospital. Of them, abnormal thyroid findings were discovered in 181 patients and we studied the result of further evaluation or follow-up PET-CT. RESULTS: Thyroid cancer was diagnosed in 26 patients, including metastatic cancer in 3 patients, and non-operated primary cancer in 2 patients. Other 21 patients received operation, which in all histopathologically revealed papillary carcinoma. The mean age of the 21 patients was 55.4 years. Nine patients had a history of radiotherapy. The site of malignant nodule was discordant between PET-CT and histopathologic result in 6 patients. The mean size of malignant nodules was 9.45 mm (0.1~23 mm) with microcarcinoma in 10 patients (47.6%). The mean interval between diagnoses was 15.8 months, and in 4 patients operations for two malignancies were performed in a same day. The incidence of thyroid cancer was significantly high in female patients, but the differences of incidence among different cancer groups were not significant for female patients. CONCLUSION: Early diagnosis of synchronous or secondary thyroid cancer by PET-CT in cancer patients can make early treatment and better strategies for multiple malignancies possible.
