A Rare Case of Cardiac Metastasis from Colon Cancer.

It is very rare for colorectal neoplasms to metastasize to the heart in the worldwide medical literature; only a single case of well-documented colorectal cancer metastasis to the left atrium was found. The case of a 66-year-old man is explained in this paper, who was suffering from metastatic adenocarcinoma of the colon that included the left atrium. In transthoracic and transesophageal echocardiography, a large multilobulated mass was present in the left atrium. An accidental pulmonary mass was also seen in a lung spiral CT scan. The cardiac mass was taken out, and a biopsy was obtained from the pulmonary mass. Adenocarcinoma was seen in histological assessment. Immunohistochemical staining was carried out to examine the expression of cytokeratin 7, cytokeratin 20, and caudal-related homeobox transcription factor 2 (CDX2) to determine the origin of the adenocarcinoma. In addition, the expression of these proteins was linked to the attributes of the patient and tumor. Post-surgical transesophageal echocardiography showed normal left ventricle and right ventricle function with no evidence of left atrium mass. Therefore, we suggest that asymptomatic cancer patients with a history of colorectal cancer and who have developed cardiac symptoms should be immediately examined for potential cardiac metastasis.

Chronic vertebro-jugular arteriovenous Fistula secondary to hemodialysis catheterization: A case report.

Vertebral artery's iatrogenic arteriovenous fistula due to central venous catheterization is an uncommon vascular complication. This report depicts a case of 21-year-old male patient who underwent central venous catheterization for hemodialysis over 10 years ago and was detected with a vertebrojugular arteriovenous fistula. This report depicts a case of 21-year-old male patient who detected with a vertebrojugular arteriovenous fistula after 10 years of hemodialysis through central venous catheterization. The surgical treatment was successfully performed.

Evaluation of liver function tests after coronary artery bypass surgery (CABG).

BACKGROUND: Coronary artery bypass graft surgery (CABG) may have systemic effects on the body organs as liver. The purpose of present study was to evaluate changes in liver function tests(LFT) after on-pump CABG surgery and risk factors associated with LFT changes.Also, the incidence of acute liver injury after on-pump CABG is determined. METHODS: 385 patients who underwent on-pump CABG surgery were randomly selected.Preoperative and intraoperative risk factors were obtained from their medical records .Postoperative liver function tests at 24, 48 and 72 hours following surgery and discharge time were compared with the preoperative ones. A univariate linear regression analysis was used to assess the possible relationships between these changes and the preoperative and intraoperative risk factors. RESULTS: Statisitcal analysis revealed direct and significant relationship between LFT changes and pump time, aortic cross-clamp clamp time and use of intra-aortic balloon pump(IABP). Also a medical history of previous myocardia infarction was significantly related to the changes in direct bilirubin in the first 48 hours following surgery.level of preoperative left ventricle ejection fraction,smoking and using opium had significant correlation with postoperative AST changes in different days.In 12.9% of patients, the aminotransferases levels increased to more than three folds over normal upper limit but the probability for incidence of acute ischemic liver injury (transient increase in aminotransferases to over 500IU/L) was 0.77%. CONCLUSION: Using techniques to reduce clamp and pump time when possible is important during CABG. Probable liver injuries post inserting IABP should be expected for appropriate monitoring and treatment.
