Persistent tracheostomy stoma.

Abstract

Prolonged presence of a tracheostomy tube or prolonged tracheostomy stoma can result in a failure of spontaneous closure. The stoma may remain open until surgically closed. Muscle flaps as well as skin flaps can be used to close the persistent tracheostomy stoma. These flaps seal the stoma, provide soft tissue between the trachea and the skin, and allow a satisfactory cosmetic result. The sternohyoid muscle is readily accessible for this purpose. This procedure was used in five patients with a satisfactory result in each.

Congenital intrahepatic portosystemic venous shunt: sonographic and magnetic resonance imaging.

We report an intrahepatic portosystemic venous shunt (IPVS) detected by ultrasound in an asymptomatic newborn. The lesion, which was further documented using color Doppler ultrasound and magnetic resonance imaging (MRI), had almost totally disappeared 6 months later without any treatment. Intrahepatic portosystemic venous shunts (IPVS) are uncommon and their etiology is controversial. Some cases of IPVS have been reported in the literature, most of them in adult patients with portal hypertension and cirrhosis of the liver. However, only scattered reports describe IPVS in the absence of liver pathology. A revision of the proposed etiologies of IPVS is made and the usefulness of gray-scale and color Doppler sonography and MRI in diagnosing IPVS is discussed.

Factors influencing outcome in patients with gastrointestinal fistula.

The analysis of the prognostic factors in patients with gastrointestinal fistula requires an assessment of the quantitative and qualitative characteristics of the study population. General patient characteristics such as age, presence and degree of malnutrition, levels of plasma proteins, diagnosis of cancer or inflammatory bowel disease, or systemic sepsis must be considered, as well as local fistula characteristics. Besides the local anatomic characteristics of the fistulous tract, other factors such as fistula output, organ of origin, cause, and duration of the fistula must be considered in the assessment of a fistula patient. It is recognized, however, that it is very difficult to conclude that the presence of a single prognostic factor increases the risk in patients as complex and heterogeneous as those with digestive fistulas. It remains to be shown whether the combination of several predictive factors may enhance the chances of accurately predicting fistula closure and mortality in digestive fistulas.

Embryological basis of some aspects of cerebral vascular fistulas and malformations.

The literature on the formation of cerebral veins is reviewed to obtain a better understanding of some cerebrovascular anomalies. Clinical observations such as the entry of the superior ophthalmic vein into the cavernous sinus through the inferior rather than the superior orbital fissure, the relative infrequency of middle cerebral vein backflow in the presence of an extensive cavernous fistula, and the relative infrequency of hemorrhage in relation to the inferior petrosal fistula all relate to the persistence of an older venous pathway. The frequent occurrence of hemorrhage in association with the superior petrosal sinus fistula and the frequent failure of the superior petrosal sinus to connect to the cavernous sinus similarly have an embryological explanation. The frequent association of the vein of Galen aneurysm and an absent or deformed straight sinus probably relates to the time at which the paired internal cerebral veins fuse into one channel. It is speculated that the origins of cerebral venous malformations (CVMs) and arteriovenous malformations (AVMs) probably relate to sequential formation and absorption of surface veins, which occur in human embryonic development mainly in the 40- to 80-mm length interval, although persistent AVM growth is possible even after birth. The frequent absence or anomaly of the middle cerebral vein and its failure to communicate with the cavernous sinus in the presence of both CVMs and AVMs are linked to the late development of that vein and to its even later connection to the cavernous sinus.
