Complication of cesarean section: pregnancy on the cicatrix of a previous cesarean section.

OBJECTIVE: To probe into the clinical manifestation, diagnosis, as well as treatment of pregnancy on the cicatrix of a previous cesarean section at the uterine isthmus in the first trimester. METHODS: Analysis of 14 patients with pregnancy on the cicatrix of a previous cesarean section at the uterine isthmus in the first trimester was made after conservative treatment by drugs from January 1996 to December 1999. RESULTS: The 14 patients with a pregnancy on the cicatrix of a previous cesarean section at the uterine isthmus in the first trimester were painless, had slight vaginal bleeding, and concurrently had increased serum beta-subunit human chorionic gonadotropin (beta-HCG). Doppler ultrasonic examination revealed an obvious enlargement of the previous cesarean section cicatrix in the uterine isthmus, and found a gestational sac or mixed mass attached to the cicatrice, with a very thin myometrium between the gestational sac and bladder walls. Among the 14 patients, 12 patients had crystalline trichosanthes injected into the cervix, mifepristone taken orally, or methotrexate in the form of intramuscular injection. Following this procedure, their serum beta-HCG dropped to normal. The other 2 patients had a total hysterectomy. CONCLUSIONS: Pregnancy on the cicatrix of a previous cesarean section at the uterine isthmus in the first trimester is a complication of cesarean section. Early diagnosis and effective conservative treatment by drugs are instrumental in decreasing the potential occurrence of uterine rupture, which is also conducive to preserving the patient's future fertility.

[The ultrasonic assessment of the cicatrix after a past cesarean section].

A supersonic study of the lower uterine segment of pregnant women which have had a Caesarean operation in the past has been made. The aim of this study is the confirmation of the supersonic scanning as a part of the struggle for diminution of the second abdominal deliveries. Twenty-six pregnant women with anamnesis of Caesarean operation were observed. The following conditions have been kept: precise probable term of delivery, gestational period--35-37 g.w., one foetus in head position, unspoiled amniotic fluid and full urinary bladder. It is obligatory a longitudinal and cross scanning in the area of the cicatrix to be made. For the assessment of the cicatrix sufficiency the author has applied supersonic criteria known in the literature. They include: shape, thickness, incessancy, outside lines and echo structure of the lower uterine segment. The results show: the scar is sufficient in 24 women--it has a triangular form in the lower uterine segment, even outside lines, the thickness of the cicatrix is above 3-5 mm it is incessant and with homogeneous echo structure. In 2 of th pregnant women there are data for inadequacy-the form is like a balloon, the cicatrix has got thinner under 3 mm, the incessancy of the lower segment is absent-it is with defects and uneven outside lines, the echo structure is heterogeneous with predominance of increased echogenicity. According to the way of delivery the results are confirmed pathohistologically, by microscope or by manual palpation. The effectiveness of the supersonic assessment of the cicatrix has been shown.

[The morphological characteristics of the cicatrix in repeat cesarean section].

It has been established that the cicatrix formation after a Caesarean operation is conditioned by various factors remaining to a large extent an individual reaction. Cicatrix structure, its vascularization, its relationship with surrounding muscular tissue and the presence or absence of inflammatory changes have their peculiarities. By a number of biopsies from the cicatrix area after a Caesarean operation we have tried to estimate the sufficiency of the cicatrix studying its morphological characteristics. For the investigation 2-3 biopsies on the average were taken from a total of 58 women. The histological and histochemical methods applied enabled us to determine quite precisely the quality of the cicatrix.

[Rupture of the uterine cicatrix in vaginal delivery after a prior cesarean section].

In the present investigation 740 deliveries were followed-up after undergone one or more cesarean sections (29.30%). 420 of deliveries were studied retrospectively and 320-prospectively. 436 women (58.91%) out of 740 women with cesarean section underwent repeated cesarean section, but 304 women (41.09%) delivered vaginally. 340 women delivered vaginally all together and the uterine cicatrix ruptured in 4 women without cases with maternal mortality, but a child died on the second day after delivery. The number of pure ruptures of the cicatrix was 3 as the percentage corresponded to 0.98%. In conclusion the author thinks that the spontaneous and traumatic rupture of the intact uterus is complete and catastrophic frequently. On the contrary the rupture of transverse uterine cicatrix is incomplete most frequently without special consequences for the mother and fetus.

Mitomycin-C in the treatment of tracheal cicatrix after tracheal reconstruction.

OBJECTIVE: To demonstrate the potential use of Mitomycin-C (MMC) in the treatment of difficult and recurrent tracheal stenosis. DESIGN: Case series. SETTING: Tertiary care setting. PATIENTS: A retrospective chart review was performed on five pediatric patients with severe, recurrent tracheal granulation and cicatrix after tracheal reconstruction who were treated with topical MMC as an adjunct to bronchoscopy and laser treatment. MMC was applied intraoperatively on saturated pledgets at a dose of 0.1 mg/ml for 2 min to the area where the cicatrix had been lysed. The five patients were able to be decannulated. DISCUSSION: Mitomycin-C is an anti metabolite known to inhibit fibroblast proliferation in vitro. This agent has been used with a high success rate in glaucoma filtration surgery to promote patency of the trabecula. The results of this preliminary application in the pediatric airway as well as the mechanism of action will be discussed.

Occipitocervical fusion for reduction of traumatic periodontoid hypertrophic cicatrix. Case report.

Periodontoid hypertrophic cicatrix resulting from trauma, as demonstrated by magnetic resonance (MR) imaging, is essentially the same as that seen in rheumatoid arthritis. Recent reports suggest that, in rheumatoid arthritis, occipitocervical fusion without transoral decompression of the pannus is adequate for resolution of this anterior lesion. A case of traumatic periodontoid cicatrix is presented in which posterior fusion resulted in reduction of the anterior mass lesion, clearly demonstrated by MR imaging. The etiology of periodontoid hypertrophic scarring, both traumatic and rheumatoid, is discussed in light of MR findings, and treatment implications are considered.

Transnasal incision of restrictive nasopharyngeal cicatrix in three horses.

Three horses were found to have an extensive nasopharyngeal cicatrix that was responsible for respiratory impairment. The cicatrization was diagnosed by use of endoscopy during evaluations of the horses for inspiratory stridor. All 3 horses were treated by endoscope-guided transnasal incision of the cicatrix and were able to resume their previous activities.

[The morphogenesis of intramedullary cavities and of a glial-connective tissue cicatrix and the enzyme status of the proteolytic system in experimental spinal cord trauma].

Canine and feline experiments were conducted to study the morphology of intramedullary cavities and a glial connective tissue cicatrix, their roles in the spinal regenerative processes as compared with the altered activity of trypsin and proteolytic inhibitors in spinal fluid and serum in different periods after spinal dissection. It was shown that decreased diastasis between the ends of the cut spine, enclosure of a traumatic area from liquor of the subarachnoidal space and central canal reduced the number and area of cavities in the cerebral cicatrix and contributed to improved regeneration of intraspinal fibers. Spinal injury caused a significant increase in trypsin and to changes of the antiprotease activity of inhibitors, spinal fluid, particularly in early postoperative periods.

Management of persistent filtering cicatrix following cataract extraction.

We used a safe and simple surgical technique in the management of persistent filtering cicatrices after cataract extraction. The edematous, friable filtering cicatrix was excised entirely and a healthy fornix-based conjunctival flap was sutured over the fistula. Invariably, the fistula was very small, usually only large enough to admit a 27-gauge needle. Of the 27 eyes treated with this technique, there were two failures, but no other complications.

A technique for open trocar placement in laparoscopic surgery using the umbilical cicatrix tube.

BACKGROUND: Increasingly the open method for placement of the initial or first trocar is replacing the conventional technique with the Veress needle. Indeed, it is preferred because it affords peritoneal access under direct vision. A number of methods have been described in the literature using a variety of approaches and different instruments. METHODS: We describe a method of open trocar placement in the supra- or subumbilical region that follows a stepwise procedure and employs specific instruments sequentially, while utilizing the umbilical cicatrix pillar or tube. RESULTS: This technique has been done in 525 cases with no complications or port site hernias. CONCLUSION: This is a simple technique that is safe and easy to learn. It can be performed rapidly and is a reliable method for the insertion of the first port under vision.

Resolution of traumatic hypertrophic periodontoid cicatrix after posterior cervical fusion: case report.

The case of a 38-year-old man with delayed myelopathy 19 years after a nontreated odontoid type II fracture is reported. Magnetic resonance imaging of the craniocervical region revealed a periodontoid cicatrix. The clinical syndrome improved, and complete resolution of the retro-odontoid mass was achieved 9 months after posterior cervical fixation. The implications of this unique case for the management of myelopathy associated with nonunion of odontoid fractures are discussed.

Desmoplastic melanoma (or is it merely cicatrix?) arising at the site of biopsy within a conventional melanoma: pitfalls in the diagnosis desmoplastic melanoma.

We describe a case in which a "punch biopsy" specimen of a conventional melanoma on the cheek of a 25-year-old man led to a problem in differentiating a desmoplastic malignant melanoma from cicatrix. The circumstances of this case raise the issue of whether desmoplastic melanoma can arise at the site of trauma within a pre-existing melanoma.
