A 14-year-old boy was investigated for unexplained tachycardia and multiple pulmonary emboli demonstrated by computed tomography. A right ventricular hydatid cyst was diagnosed by echocardiography and successfully excised under cardiopulmonary bypass.

Benign mature cystic teratoma of the anterior mediastinum leading to heart failure: Report of a case

Ufuk Özergin; Niyazi Gormus; Olgun Kadir Aribas; Kadir Durgut; Tahir Yüksek

A 12-year-old male child was referred to our clinic for the surgical treatment of an anterior mediastinal mass, suspected to be a thymic cyst, which was considered to potentially lead to cardiac failure. The mass was resected completely with a median sternotomy. The postoperative course was uneventful. A pathological examination revealed a mature cystic teratoma of anterior mediastinum which is a very rare cystic tumor at this location. The incidence, diagnostic procedures, complications, and treatment of mediastinal teratomas are discussed along with a review of the literature.

Pericardial hydatid cyst was diagnosed by 2-dimensional echocardiography and magnetic resonance imaging in a 25-year-old female. At operation, an infected myocardial hydatid cyst was found on the lateral wall of the left ventricle.

[Evaluation of post-operative flow and diameter changes in brachial and ulnar arteries in coronary artery bypass surgery patients in which the radial artery is used as graft].

OBJECTIVE The radial artery is widely used in coronary bypass surgery. In these patients, forearm and hand circulation is provided by the ulnar artery. This study aimed to investigate post-operative changes in flow and diameter in brachial and ulnar arteries in patients undergoing coronary bypass surgery in which the radial artery is used as graft. METHODS Between September 2007 and September 2008, 20 patients (16 men, 4 women; mean age 57.8 years; range 44 to 70 years) underwent elective coronary bypass surgery at our clinic. The radial artery was used as graft in all cases. Pre-operatively, adequacy of the ulnar artery for forearm circulation was investigated by Allen test and duplex ultrasonography. Basal flow and diameter values of the brachial and ulnar arteries were measured. Control duplex ultrasound measurements were performed at three months post-operatively. Flow and diameter changes in the brachial and ulnar arteries were recorded. RESULTS Significant increase was shown in ulnar artery flow and diameter values in post-operative measurements. A significant increase was observed in brachial artery diameter, accompanied by a relative decrease in flow value. There were no mortality or ischemic complications in our study. Transient paresthesia as a neurological complication was observed in 4 patients. CONCLUSION Radial artery use for coronary bypass surgery leads to significant changes in ulnar and brachial arteries. All flow and diameter changes can be detected by color Doppler ultrasonography in the early stages. These adaptation mechanisms show that the radial artery can be safely harvested as graft material.

Peripheral arterial injuries: A study of four hundred and seventeen cases

Ufuk Özergin; Niyazi Gormus; Kadir Durgut; Tahir Yüksek; Hasan Solak

In this article 417 patients are examined retrospectively. They are reviewed according to their ages, sex, types of injuries, clinical findings, surgical approaches and complications. Most of them were young males (78%) between 11–30 years of age (65%) and 74% were injured by sharp weapons and gunshots. Femoral artery injuries were seen in 29% of all patients. Amputation was performed in 6.4% of cases, but in the popliteal artery group the amputation ratio was 14%. Thirteen patients died from hypovolemic shock or acute renal failure (3.12%).

A giant right atrial myxoma: Case report

Cevat Özpinar; Sami Ceran; Mehmet Yeniterzi; Tahir Yüksek; Ufuk Özergin; Hasan Solak

Right atrial myxomas have rarely been reported. The authors describe a giant hourglass-shaped atrial myxoma consisting of three lobes; one of them had protruded into the right ventricle. Its size was 18×7×5 cm and weight was 170 g. The authors were not able to find another myxoma as big as this one in the literature, so they are reporting it. They review and discuss the literature involving the subject.

Cevat Özpinar; Sami Ceran; Mehmet Yeniterzi; Tahir Yüksek; Ufuk Özergin; Hasan Solak

An eleven-year-old boy was operated on for a left-sided pulmonary artery aneurysm. The same patient had also been operated three years earlier because of a right sided aneurysm.

Myocardial cystic hydatids causing cardiac tamponade. Report of cases

Hasan Solak; Tahir Yüksek; Mehmet Yeniterzi; Özkan Akkoç; Nazif Anil; Sami Ceran

Four patients with cystic hydatids located in pericardium and myocardium were admitted. Cardiac tamponade was determined in 1 of these cases. Surgical treatment was instituted for all cases. Transpericardial cardiac palpation was emphasized in cases where thoracotomy was necessary due to the lung cystic hydatids.

New World's old disease: cardiac hydatid disease and surgical principles.

Summary Background: Hydatid cyst is a parasitic disease caused by infection with the Echinococcus granulosus tapeworm larva. It is a major public health problem in endemic regions. Cardiac involvement of the disease is rare. Methods: Between 1985 and 2015, 12 patients were admitted to our clinic with a possible diagnosis of cardiac hydatid disease. Of these patients, six (50%) were male and six (50%) were female. Mean age of the patients was 42.6 years. Results: The most common location of cardiac hydatid disease was left sided (six patients, 50%). Five (41.7%) patients had cysts located in the right heart, whereas one (8.3%) had a cyst in the interventricular septum. Eleven (91.7%) of the patients were operated on via median sternotomy and the remaining one was operated on via a left anterolateral thoracotomy. Ten (83.3%) of the patients were operated on using cardiopulmonary bypass under moderate hypothermia, whereas the remaining two (16.7%) had off-pump surgery. There was no surgical mortality in our series. All patients were discharged with medical therapy (mebendazole or albendazole) for the duration of six months. No recurrences were observed in their follow ups. Conclusion: Although cardiac hydatid disease is rare, its prevalence seems to have increased in the last decade. Any patient with suspected cardiac symptoms suggesting mass lesions should be considered for a differential diagnosis of cardiac hydatid disease, especially in developing countries. Definitive treatment is removal of the cyst, combined with medical therapy.

New Technique for Reinforced Sternal Closure

Ufuk Özergin; Kadir Durgut; Cevat Özpinar; Niyazi Gormus; Güven Sadi Sunam; Tahir Yüksek; Hasan Solak

A simplified method of reinforced sternal closure is described. Figure-of-8-shaped sutures of no. 5 stainless steel wire are inserted with 2 Sterna-Bands between them. The advantages of this technique are simplicity, effectiveness, and speed.
