Elevation of Sunken Flap Due to Ventriculo-Peritoneal Shunt

In relation to the article “Surgical Practice in Resource-Limited Settings: Perspectives of Medical Students and Early Career Doctors: A Narrative Review” [1], we would like to mention how resource constraints affect surgical practice directly by modification of: (1) presurgical lesion localization technique (e.g., skin marking is used before breast surgery, instead of parenchymal marking with hook wire, partially due to resource constraint [2]); (2) storage and retrieval of investigation reports (handwritten-papers in case file/notebook with patient, electronic medical records); (3) surgical technique, as in the following case.

A patient had normal contour of surgical flap after resection of intracranial tumor and ventriculo-peritoneal (VP) shunt placement (Figure 1). When she came for follow-up MRI after 7 months, we noticed that the surgical flap was depressed/sunken (Figure 2). Since she had new neurological deficits; bone flap elevation was done. After the flap elevation surgery, most of her new symptoms resolved and MRI showed an elevated flap (Figure 3).

Sinking/depression of the surgical flap is a known issue after placement of VP shunts for decreasing hydrocephalus.

Since programmable shunts cost around one lakh INR and nonprogrammable shunts cost around 6000 INR, usually nonprogrammable shunts are used in resource-constrained setting.

Asymptomatic patients, unconcerned about the cosmetic impact, do not require any intervention.
