Macroanatomic investigations of the blood supply of thoracic limb of Kangal dogs.

In this study, the arterial supply of the thoracic limb was investigated in Kangal dogs. Twelve adult healthy Kangal dogs of either sex were used. Latex was injected into the common carotid artery, and then the axillary artery was dissected. The axillary artery is a continuation of the subclavian artery and supplies the thoracic limb in Kangal dogs. The axillary artery gave off a deltoid branch and external thoracic, lateral thoracic, and subscapular thoracic arteries in its course along the thoracic wall. The axillary artery continues distally as the brachial artery in the arm. The brachial artery gives rise to the cranial humeral circumflex, deep brachial, bicipital, ulnar collateral, superficial brachial, transverse cubital, and common interosseus arteries. It continues as the median artery after giving off the common interosseus artery. It was observed that the deep antebrachial artery arose from the median artery at the proximal third of the forearm. In the distal third of the forearm, the median artery divided into the palmar carpal and dorsal carpal branches. The deep palmar branch of the radial artery and deep branch of the palmar branch of the caudal interosseus artery form the deep palmar arch. The median artery joined the superficial branch of the palmar branch of the caudal interosseus artery to constitute the superficial palmar arch. The radial artery and cranial interosseus artery contributed to the dorsal carpal rete. The ulnar artery contributed to the formation of the deep and superficial palmar arches.

Causative factors in first trimester abortion failure.

OBJECTIVE: To evaluate the main contributors to failed first trimester abortions. PATIENTS AND DESIGN: Forty-two cases of unintentional continued pregnancy were detected among 23,000 termination procedures performed between 1989 and 1995. The patients were diagnosed either at follow-up visits or at the time of operation due to abnormal pelvic findings or discrepancy between the expected and obtained tissue. RESULTS: The failure rate was found to be 0.18%. Among the patients with failed abortion 8 patients had unsuspected anomalies; two of these patients conceived with an intrauterine device in position; 7 patients had uterine malposition (2 markedly anteverted and 5 markedly retroverted), and 2 patients had leiomyomas. No genital disorder was identified in the remaining 25 women. Among these 25 women, 10 had gestations beyond 8 weeks, for which suction curettage followed by sharp curettage was performed. Among the remaining 15 in whom only suction curettage was used for termination, 13 had less than 6 weeks of gestation at the time of pregnancy termination. CONCLUSION: When a termination fails, when scanty tissue is obtained, or when doubt exists about the termination, an extrauterine pregnancy must be ruled out and other causes of termination failure should be considered such as technical failure, uterine anomaly, or malposition.

Reproductive outcome after metroplasty.

OBJECTIVE: To evaluate the impact of abdominal metroplasty for symmetric uterine anomalies on reproductive performance. METHOD: A retrospective analysis of 24 patients who conceived following metroplasty for symmetric congenital anomalies during a 5-year period. RESULTS: In patients with poor obstetric histories before surgery, the overall fetal survival rate increased from 2.5%, before treatment to 73.3% after treatment and 90.5% of women gave birth to a surviving infant. The remaining three patients suffering from infertility delivered a full-term infant after metroplasty. Antenatal complications occurred in 56.7% of the pregnancies. CONCLUSION: Abdominal metroplasty clearly improves fetal survival particularly in women suffering from a history of poor obstetric outcome associated with symmetric malformations.

Rupture of the uterus.

OBJECTIVES: To investigate the frequency of ruptured uterus, possible etiologic factors and fetomaternal outcomes. METHODS: The birth records of 58262 deliveries at Dr Zekai Tahir Burak Women's Hospital from 1 January 1990 to 31 December 1992 were reviewed and the results compared with those of two previous studies reported from this hospital on the same subject. RESULTS: Forty uterine ruptures occurred between 1990 and 1992, with a frequency of 0.068% (1/1457). All occurred spontaneously but 10 (25%) had no previous surgery, whereas 30 followed previous cesarean section. There was no traumatic uterine rupture during this period. Fetal mortality was 32.5% and no maternal deaths were recorded. CONCLUSION: The rate of ruptured uterus has declined among our hospital population as etiologic factors responsible for the complication have been reduced.

Treatment of Bartholin's cyst and abscess: excision versus silver nitrate insertion.

In a prospective randomized study, intracavitary silver nitrate (AgNO3) stick insertion (n = 25) was compared to the conventional excision technique (n = 25) for Bartholin's cyst or abscess. Two groups were similar with regard to age, previous Bartholin's cyst/abscess and size of the cyst. Operation and healing time was significantly shorter in the AgNO3 group (P < 0.001, P < 0.001, respectively). Chemical burning in the vulva was observed in one patient in the AgNO3 group, whereas hematoma on the operation site occurred in two patients in the excision group. Scar formation was found in two patients in whom excision was performed. Patients were followed for a period of 2 years and recurrence was not found in any of the cases in both groups. We conclude that, AgNO3 insertion treatment for Bartholin's cyst and abscess is as effective as excision and is associated with fewer complications. Because it is simple and inexpensive, it is an attractive alternative treatment modality for this common gynecological disease.

Acceleration of hepatobiliary dynamics in liver transplant donors.

This study compared hepatobiliary scintigraphy findings in livers before and after liver graft donation to examine whether there is a change in hepatobiliary dynamics. Nine donors underwent hepatobiliary scintigraphy with intravenous injection of Tc-99m mebrofenin 1 day before and during the first week after left liver lobectomy. Five donors also underwent additional scintigraphy more than 1 year postsurgery. Images were acquired every second for the first minute, and then every minute for the next 40 minutes. Hepatic arterial perfusion index and portal perfusion index(PPI) were calculated from the images acquired during the first minute. For the function phase the computed parameters included: hepatic extraction efficiency, (HEE), time to appearance of activity in the intrahepatic biliary channels, and in the intestine, time to half maximal activity, and activity retained in the liver parenchyma at 40 minutes. Time to appearance of intrahepatic biliary channels and of intestinal activity was shorter among scintigraphies obtained within 1 week postsurgery compared to the preoperative values. Early after the operation HEE increased and PPI decreased significantly. Visual inspection of the scintigraphy scan obtained in all donors, within the first week postsurgery revealed hypertrophy of the right liver lobe. None of the patients showed progression of right lobe activity to the left side, even among scans obtained more than 1 year after donation. Reduced time to activity in the biliary channels and intestine and increased HEE suggest acceleration of hepatobiliary dynamics.
