An unexpected complication of robotic cardiac surgery: Pneumomediastinum

Pneumomediastinum is a rare entity that is defined as free air in the mediastinal space. A 26-year-old male patient was admitted with pneumomediastinum as an unexpected complication of robotic surgery. Diffuse subcutanous emphysema was observed suddenly on Postoperative Day 3 without respiratory distress. Air trapping into the mediastinum was seen on chest X-ray and computed tomography. The patient was followed in the intensive care unit for 7 days and managed conservatively. Subcutaneous emphysema reduced gradually. In conclusion, although it is a rare condition, pneumomediastinum should be kept in mind as a complication of robotic cardiac surgery.

First sign of native valve endocarditis in the COVID-19 pandemic: Acute arterial septic embolism in the lower extremity

he clinical manifestations of infective endocarditis are variable. Late diagnosis of the disease can lead to clinical catastrophe and even death. Although its symptomatology is broad, the initial diagnosis can sometimes be made after complications, particularly during COVID-19 pandemic days. It should be noted that during the pandemic period, patients with mild infective endocarditis symptoms may be confused with covid 19 infection symptoms. In this report, we aim to present that lower extremity ischemia was the first sign of infective endocarditis in a 77-year-old female patient with complaints of sudden onset of pain and coldness in the leg. The patient underwent an embolectomy and embolic material of 1x1.5 cm was removed from the left common femoral artery

Huge Intravascular Tumor Extending to the Heart: Leiomyomatosis

Intravenous leiomyomatosis (IVL) is a rare neoplasm characterized by histologically benign-looking smooth muscle cell tumor mass, which is growing within the intrauterine and extrauterine venous system. In this report we aimed to present an unusual case of IVL, which is originating from iliac vein and extended throughout to right cardiac chambers. A 49-year-old female patient, who was treated with warfarin sodium due to right iliac vein thrombosis, was admitted to our department with intermittent dyspnea, palpitation, and dizziness. Physical examination was almost normal except bilateral pretibial edema. On magnetic resonance venography, there was an intravenous mass, which is originated from right internal iliac vein and extended into the inferior vena cava. Transthoracic echocardiography and transesophageal echocardiography revealed a huge mass extending from the inferior vena cava through the right atrium, with obvious venous occlusion. Thoracic, abdominal, and pelvic MR showed an intravascular mass, which is concordant with leiomyomatosis. Surgery was performed through median sternotomy. A huge mass with 25-cm length and 186-gr weight was excised through right atrial oblique incision, on beating heart with cardiopulmonary bypass. Histopathologic assessment was compatible with IVL. Exact strategy for the surgical treatment of IVL is still controversial. We used one-stage approach, with complete resection of a huge IVL extending from right atrium to right iliac vein. In such cases, high recurrence rate is a significant problem; therefore it should be kept in mind

Preoperative Frontal Qrs-T Angle is An Independent Correlate of Hospital Length Of Stay and Predictor Of Haemodynamic Support Requirement Following Off-Pump Coronary Artery Bypass Graft Surgery

OBJECTIVES: With the adoption of novel operative techniques and aggressive care protocols that facilitate earlier extubation and mobilization of patients, postoperative length of stay (LOS) following coronary artery bypass graft surgery (CABG) has declined. However, there is paucity of information regarding preoperative electrocardiographic predictors of LOS following CABG. In this study, we investigated whether frontal QRS-T angle, which is an abnormal repolarization marker in prediction of various cardiovascular events, was an independent correlate of postoperative hospital LOS for off-pump CABG. Furthermore, we evaluated independent predictors of vasopressor agent/intra-aortic balloon pump (IABP) support requirement following off-pump CABG. METHODS: In this observational study, 78 patients with stable angina, who were scheduled for elective coronary artery bypass surgery following diagnosis of obstructive coronary artery disease by conventional angiography, were enrolled. RESULTS: Left ventricular ejection fraction (LVEF) was significantly lower and vasopressor agent/IABP support requirement and incidence of sustained atrial or ventricular arrhythmias was higher in patients with wide QRS-T angle (P < 0.05). Postoperative hospital LOS was also longer in this group. From the preoperative characteristics, wide frontal QRS-T angle was found to be an independent correlate of postoperative hospital LOS (B +/- SD: 11.97 +/- 0.62, P <= 0.01). Wide frontal QRS-T angle was also found to be an independent predictor of vasopressor agent/IABP support requirement postoperatively (OR: 7.87, P <= 0.01). CONCLUSIONS: Prediction of the hospital LOS and patient outcome following CABG is of great importance. Being easily obtainable via standard 12-lead electrocardiogram and its low cost may make frontal QRS-T angle a beneficial marker for reducing both patient-based morbidity and economic burden.WoSScopu

Oxaliplatin Induced Digital Ischemia and Necrosis

Introduction. Digital ischemia is a rare complication of several chemotherapeutic medications. We aimed to present a patient with digital ischemia, secondary to a new generation chemotherapeutic drug, oxaliplatin. Case Report. 62-year-old woman presented to our department with severe pain, paresthesia, and distal acrocyanosis on her right hand fingertips. Her complaints started five days after the third cycle of a chemotherapy protocol consisting of 5-fluorourasil (5-FU), folinic acid, and oxaliplatin due to advanced colon carcinoma. On physical examination, hemorrhagic and partly ulcerative lesions were detected at her right hand fingertips. Radial and ulnar pulses were absent at affected side. Digital subtraction angiography revealed severe vascular resistance in the affected extremity. Iloprost trometamol treatment was started with the dosage of 1 ng/kg/min. In addition, low-molecule-weight heparin was used for preventing possible microemboli. Symptomatic relief was provided after five days, and patient was discharged on 7th day of treatment. Discussion. The pathogenesis of oxaliplatin induced vascular toxicity remains unclear. Endothelial damage, increased adherence of platelets, deposition of immune complexes as an immunologic effect of oxaliplatin, and hypercoagulable state may be the reason for arterial thrombosis, digital microemboli, possible digital ischemia, and their several consequences
