Combined pharmacomechanical thrombectomy with selective catheter-directed thrombolysis in patients with acute proximal deep vein thrombosis.

Background: The aim of this study was to evaluate the characteristics and the outcomes of combined percutaneous pharmacomechanical thrombectomy with selective catheter-directed thrombolysis for acute iliofemoral deep vein thrombosis. Methods: Between March 2018 and February 2020, a total of 37 patients (21 males, 16 females; mean age: 55±13.8 years; range, 21 to 79 years) with symptomatic acute iliofemoral vein thrombosis who underwent combined percutaneous pharmacomechanical thrombectomy and catheter-directed thrombolysis were retrospectively analyzed. All patients received a three-step therapy: (i) insertion of a temporary inferior vena cava filter, (ii) percutaneous pharmacomechanical thrombectomy via rotational mechanical thrombectomy device with an adjuvant 0.15 mg/kg recombinant tissue-type plasminogen activator alteplase, and (iii) catheter-directed thrombolysis with continuous 1 mg/h tissue-type plasminogen activator alteplase. Data including demographic characteristics of the patients, bleeding complications, technical success, and adjuvant angioplasty rates were analyzed. The Kaplan-Meier analysis was used to evaluate freedom from re-thrombosis at 3, 6, and 12 months of follow-up was calculated. Results: The majority of the patients had left-sided (n=22, 59.4%) proximal deep vein thrombosis. Successful insertion of the inferior vena cava filter was achieved in 97.2% (n=36) of patients. The technical success rate was 89.1% (n=33). Adjuvant venous angioplasty was performed in four patients (10.8%) and no venous stents were used. No major bleeding was occurred, while minor bleeding was observed mostly in the form of hematuria (n=12, 32.4%). No mortality was observed. The 3, 6, and 12-month freedom from re-thrombosis rates were 96.3%, 92.6%, and 86.0%, respectively. Conclusion: Combined percutaneous pharmacomechanical thrombectomy and catheter-directed thrombolysis seems to be an effective and safe treatment of the iliofemoral acute deep vein thrombosis with acceptable minor bleeding complications post-interventionally.

Transaortic repair of concomitant mitral insufficiency in patients with critical aortic stenosis undergoing aortic valvular replacement.

BACKGROUND: In this study, we present operation technique and outcomes of transaortic mitral valve repair in high-risk patients undergoing aortic valve replacement due to severe aortic stenosis. METHODS: Between January 2005 and March 2016, a total of 11 patients (7 females, 4 males; mean age 71.2±4.1 years; range, 65 to 77 years) with severe aortic valve stenosis (aortic valve area <1 cm2 or aortic valve area index <0.6 cm2/m2) and concomitant moderate or severe mitral regurgitation (non-ischemic, regurgitant jet origin between A2-P2 portions) secondary to left ventricular dysfunction (EuroSCORE logistic score >5%, left ventricular ejection fraction <30%) who were operated were retrospectively analyzed. Aortic valve replacement and transaortic mitral edge-to-edge repair was applied to all patients. Operations were performed through sternotomy, cardiopulmonary bypass, and bicaval venous return. Transesophageal echocardiography was used to evaluate mitral valve before surgery and valve functions after surgery. Postoperative course of all patients was monitored, and postoperative complications were recorded. RESULTS: The mean preoperative ejection fraction was 24.5±4.1% and the mean transaortic pressure gradient was 35.8±4.8 mmHg. The mean aortic cross-clamp time was 62.09±10.1 (range, 43 to 76) min and the median cardiopulmonary bypass time was 90.1±11.9 (range, 66 to 114) min. No hospital mortality was observed. In the postoperative period, two patients experienced renal insufficiency. Hemofiltration was initiated in these patients and no dialysis was required at two weeks. One patient had postoperative atrial fibrillation and one patient had pericardial effusion leading to cardiac tamponade and this patient underwent reoperation. The patients were followed up for a mean of four years and control echocardiography didn"t detect increase in mitral regurgitation degree. CONCLUSION: Transaortic edge-to-edge mitral valve repair can be used in high-risk patients undergoing aortic valve replacement. This technique is feasible with shorter cross-clamp time and can reduce mortality and morbidity in selected high-risk patients.

Central retinal vein occlusion after coronary artery bypass surgery: A case report.

OBJECTIVE: The aim of this study is to report a case of central retinal vein occlusion (CRVO) after coronary artery bypass graft (CABG) surgery. In this report, we present the third case in the literature with CRVO after cardiopulmonary bypass (CPB), and the first case after CABG. CASE REPORT: A 59-year-old male patient complaining of chest pain was admitted to our hospital. The patient underwent an elective coronary angiography and was diagnosed with three-vessel coronary artery disease. An uneventful coronary artery bypass graft operation was performed using CPB. On the second postoperative day, the patient described blurring and decreased vision in his left eye, whereas the right eye was normal. The anterior-posterior segment was examined by an ophthalmologist who diagnosed central retinal vein occlusion, using a visual acuity test, fundoscopy. After 5 months of treatment, there has been no improvement in the patient's visual acuity. CONCLUSION: As two previous case reports indicated CRVO can be a rare complication after CPB, this study demonstrated that CRVO can also be a complication of CABG. Therefore, CRVO should always be considered as a potential complication after cardiac surgery.

Coronary Arteriovenous Fistulas in Adult Patients: Surgical Management and Outcomes.

Objective: The aim of this study was to describe the demographic, clinical and anatomic characteristics of coronary arteriovenous fistulas in adult patients who underwent open cardiac surgery and to review surgical management and outcomes. Methods: Twenty-one adult patients (12 female, 9 male; mean age: 56.1±7.9 years) who underwent surgical treatment for coronary arteriovenous fistulas were retrospectively included in this study. Coronary angiography, chest X-ray, electrocardiography and transthoracic echocardiography were preoperatively performed in all patients. Demographic and clinical data were also collected. Postoperative courses of all patients were monitored and postoperative complications were noted. Results: A total of 25 coronary arteriovenous fistulas were detected in 21 patients; the fistulas originated mainly from left anterior descending artery (n=9, 42.8%). Four (19.4%) patients had bilateral fistulas originating from both left anterior descending and right coronary artery. The main drainage site of coronary arteriovenous fistulas was the pulmonary artery (n=18, 85.7%). Twelve (57.1%) patients had isolated coronary arteriovenous fistulas and 4 (19.4%), concomitant coronary artery disease. Twenty (95.3%) of all patients were symptomatic. Seventeen patients were operated on with and 4 without cardiopulmonary bypass. There was no mortality. Three patients had postoperative atrial fibrillation. One patient had pericardial effusion causing cardiac tamponade who underwent reoperation. Conclusion: The decision of surgical management should be made on the size and the anatomical location of coronary arteriovenous fistulas and concomitant cardiac comorbidities. Surgical closure with ligation of coronary arteriovenous fistulas can be performed easily with on-pump or off-pump coronary artery bypass grafting, even in asymptomatic patients to prevent fistula related complications with very low risk of mortality and morbidity.

Miller-Fisher syndrome after coronary artery bypass surgery.

Miller-Fisher syndrome (MFS) is an uncommon neurological disorder that is considered a variant of the Guillain-Barre syndrome (GBS). It is clinically defined by a triad of symptoms, namely ataxia, areflexia and ophthalmoplegia. These acute inflammatory polyradiculopathic syndromes can be triggered by viral infections, major surgery, pregnancy or vaccination. While the overall incidence of GBS is 1.2-2.3 per 100 000 per year, MFS is a relatively rare disorder. Only six cases of GBS after cardiac surgery have been reported, and to our knowledge, we describe the first case of MFS after coronary artery bypass surgery. Although cardiac surgery with cardiopulmonary bypass may increase the incidence of MFS and GBS, the pathological mechanism is unclear. Cardiac surgery may be a trigger for the immune-mediated response and may cause devastating complications. It is also important to be alert to de novo autoimmune and unexpected neurological disorders such as MFS after coronary bypass surgery.

Biventricular transient systolic dysfunction after mitral valve replacement: Pericardial decompression syndrome.

BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature. CASE REPORT: A 43-year-old woman who underwent mitral valve replacement three weeks ago admitted to our hospital with dyspnea, tachycardia, and atrial fibrillation. Large quantity of pericardial fluid (35mm in the posterior wall, 25mm in the anterior wall) with partial compression of the right ventricle and 50% left ventricle ejection fraction (LVEF) was determined via transthoracic echocardiography (TTE). After creation of pericardio-pleural window, more than 1000ml of serosanguineous fluid were quickly removed from the pericardial space. During the following hours of the decompression, the patient's condition deteriorated and overt pulmonary edema developed. On the second day, biventricular systolic dysfunction, global diffuse hypokinesia and 15-20% LVEF was observed via TTE. High-dose inotropic support and diuretics was continued. During follow up she was progressively weaned off inotropes, LVEF were raised to 35%. Two weeks later, repeated TTE showed normal biventricular systolic function and LVEF was 50%. CONCLUSION: We recommend gradual removal of pericardial effusion under hemodynamic monitoring, especially in patient with postcardiotomy tamponade.

Management of Traumatic Aortic and Splenic Rupture in a Patient With Ascending Aortic Aneurysm.

Traumatic aortic rupture is rupture of all or part of the aortic wall, mostly resulting from blunt trauma to the chest. The most common site of rupture is the aortic isthmus. Traumatic rupture of the ascending aorta is rare. A 62-year-old man with a family history of ascending aortic aneurysm was referred to our hospital after a motor vehicle accident. He had symptoms of cardiogenic shock. A contrast-enhanced computed tomographic scan revealed rupture of the proximal ascending aorta and an ascending aortic aneurysm with a diameter of 55 mm at the level of the sinuses of Valsalva. Transthoracic echocardiography at the bedside revealed severe aortic valvular insufficiency. We performed a successful Bentall procedure. During postoperative recovery, the patient experienced a cerebrovascular accident. Transesophageal echocardiography did not reveal thrombosis of the mechanical prosthesis. The patient's symptoms resolved in time, and he was discharged from the hospital on postoperative day 47 without any sequelae. He has been symptom free during a 6-month follow-up period. We suggest that individuals who have experienced blunt trauma to the chest and have symptoms of traumatic aortic rupture and a known medical history of ascending aortic aneurysm should be evaluated for a rupture at the ascending aorta and the aortic isthmus.

Heyde's syndrome.

Gastrointestinal bleeding due to colonic angiodysplasia can be associated with calcified aortic stenosis. This association is referred to as Heyde's syndrome. Aortic valve replacement can prevent recurrent gastrointestinal bleeding in these cases. We describe the case of a 46-year-old woman with congestive heart failure related to aortic stenosis, and severe anemia, with multiple angiodysplasias on the ileum and colon. After aortic valve replacement, there were no further episodes of bleeding and her hemoglobin levels normalized.

Solitary secondary malignant melanoma of clavicle two years after enuclation for ocular melanoma.

Solitary metastasis of uveal melanoma to bone is extremely rare and usually associated with other organ involvement. We present a rare case of an ocular melanoma patient presenting with solitary metastasis to the clavicle two years after enucleation, without any other organ involvement. In this report, we tried to present our treatment strategy for the solitary metastasis of bone.

Recurrent cardiac metastasis of primary femoral osteosarcoma: a case report.

A 17-year-old female patient with a history of surgery for primary femoral and metastatic lung osteosarcoma was admitted to our clinic with palpitations. Upon evaluation, a metastatic osteosarcoma in the left ventricle was diagnosed. Based on the collaborative decision of the oncology and cardiovascular surgery clinics, surgery was performed and the patient was discharged without any problems. According to the recommendation of the oncology clinic, chemotherapy was postponed for 6 months after surgery. Five months postoperatively, however, she had a recurrence with 2 tumors. Based on the collaborative decision, chemotherapy was initiated and in 2 months the size of the recurrent tumors had diminished. The patient is still under the care of the oncology and cardiovascular surgery clinics and continuing her chemotherapy regimen. Osteosarcomas have a high mortality. Metastatic tumors of the heart are not common. The location of the metastasis and the characteristics of the primary tumor determine the treatment modality. In some previously published reports, various treatment choices have been described. In the present case report, we present a rare case with metastatic cardiac osteosarcoma.
